Thank you, Thank you. I have a Crosman 130 pump pistol that I got about 65 years ago. It would not pump up so I got a O ring kit. I installed the kit the best that could but no joy! To ship it off and have it repaired would probably cost about the same as a new gun, so me being a cheap skate it has set in a closet for many years. I came across this video and thought "why not"......well it is back to plinking tin cans!!!! It sure gave me a lot fun times as a young teen....now it will give me more fun as an old guy! THANKS AGAIN Ray

Someone gave my dad a Benjamin Sheridan 397 P that wasn't pumping up. I watched your video and that night I took it apart and reason for that was to check other parts and clean. But I just poured alcohol in small hole and behind cup and let it sit overnight and lo n behold this worked. Appreciate your time making the video.

Blimey! I'm amazed, I bought a 2200 on an online auction, blind, it didn't pump. I was looking at diagrams and seal kits to repair it. I was a bit underwhelmed with the gun when I picked it up as it felt like a toy gun I had 50 years ago firing caps at my little brother. I used a few squirts of 99% hand sanitizer from our COVID stash. I'm pretty sure this little plinker has more power than my Air arms S410 classic. Very impressed with this video that has revitalised an old American plinker (maybe not restricted for UK market)

Made my day. I haven't picked up my 397P in years. After the alcohol flush I'm back in business....THANK YOU!!!!

I tried this on my "one pumper" Sheridan and it worked. Be patient, keep trying and you may be rewarded. Thanks for such a well-made, instructive video.

I bought a Benjamin model 342 air rifle in the 1970s. I haven't used it for over 30 years. Tried to pump it up but it did not hold any pressure whatsoever. I read about your 'Alcohol Flush' and decided to give it a shot(pun intended) last night. I pumped it up this morning and it fired like a champ. Great advice with greater results. Thanks a million!

Amazing!!! I have a Crosman Powermaster 760 I bought in 1980 (I was 23), pulled it out of storage ... no pressure at all. I was looking at rebuild kits/instructions and found your vid. I did this flush twice and let it sit for 3 days ... Bought some new Pell Oil, put 3 drops on the oil ring and TAH DAH !!! It's working perfectly. This was my varmint gun on every camping trip I ever went on (remote tent camping was my main recreation until 8 yrs ago). Thank you for helping me bring her back to life! Now, I'll watch for those pesky pocket gophers when they poke their little heads up.

I watched your video and decided to try fixing my dad's 40 year old Benjamin Franklin model 342. Unbelievable, it came to life after 2 nights of soaking. Can't wait to find some pellets and test it out. Thank you so much for sharing your knowledge.

I did this to my old 2100, Powermaster66 & 392. All were still pumping but they perform WAY better now.! Much Increased power with less pumps. Very glad I found your video!

Thank you for the great tip. I have an old Crosman Powermaster 66 that stopped working recently. I did the alcohol flush as you suggested and left it overnight. I tried it a little while ago and it's working great! Thank you again for the great tip. It's greatly appreciated! All the very best..... John C.

While doing some maintenance on my Benjamin Sheridan C9A .50 Cal. rifle, I ended up having some gun oil creep into the air pump chamber. I had zero pumping power. I found this video and gave it a try, and IT WORKED! I added the rubbing alcohol into the chamber and pump cup, let it sit over night, and the next morning all was good again. Got my beloved air rifle back in working order. Actually has more pressure then it originally had. Thank you for this video!

I have a 55+ year old model 310, which I used as a kid, that quit pumping. I tried the alcohol flush and it didn't work immediately. I left it overnight and it's not only pumping up but holding air. Thank you for this great video.

I did just what you did, and my 397 is pumping, pumping, pumping.....and holding pressure!!!! Thank you!

Man I'm ecstatic! My wife's dad had a 317 he had as a kid and stowed away in a hidden cabinet, when I discovered it, it didn't pump up! So I tried your flush! 3 times and man does it shoot great! Like a new gun, no leaks, no problems!!! I really didn't want to take it apart to repair it! Thank you so much for this video! It's a cool classic gun I wanted as a kid! Thank you so much, again!

John, I saw your video on the alcohol flush and was quite skeptical at first, but decided to give it a try with 70% alcohol on my Benjamin 317 and it didn't work so I decided to follow directions and use 91% alcohol. I did it like you, above and below the pump cup, then set it in the corner, upright and pumped it several times in the morning and lo and behold I got pressure again! Thanks a lot for sharing!

Just tried this on my 1975 Benjamin 342 and on my 1995 Benjamin 397PA. They're both working much better now. Thanks.

Took your advice and my Benjamin 397pa immediately started pumping up. I lack patience so as soon as I seen the difference I did like you said and it works like new. Thanks

THANK YOU! JUST TRIED THIS YESTERDAY ON MY DAISY 856 AND TODAY IT PUMPED UP AND FIRED. SO I PUT MORE IN AND WILL TRY IT AGAIN TOMORROW!

The inlet check valve is still not sealing as you pointed out. I've been alcohol flushing pump pneumatics for years. If it's going to work it works pretty quick. My method is to squirt, pump 2X, fire, repeat until all the seals hold air and there's no more dirt coming out of the muzzle. No need to soak overnight. Alcohol hardens and dries out the rubber seals so get some oil in the valve as soon as possible after you flush it out with alcohol. If flushing doesn't work then it needs a reseal job which is no big deal. Routine oil lubrication over the life of the gun flushes the valve out with every shot.

I am so happy I found this video last night. Earlier this week I took my Crosman 140 off of my gun rack to dust the Rifles on the Gun Rack. For the heck of it I tried to pump it up and it would not hold air. Took a extra Syringe I had around that I had left over from filling printer ink cartridges for my printer unused and poured some Rubbing Alcohol in a extra pill bottle I had around like you did and inserted it where you told us on the video to do. Did it a few times. It didn't do anything for me last night as it seemed to be leaking air from around the piston area. I thought there was no hope for it and that maybe I needed to rebuild the piston. Add more Alcohol, stood it up and walked away. Well this early afternoon I went and checked the 140 Rifle again and I could tell a big difference on the first pump. Pumped it just 2 times and tried it and it shot some air out of the barrel into a rag. Just ordered some Pelgun oil for it last night I should have on Monday. Can you suggest to me or do you have another video you can send me a link to on how to oil this 140 Rifle properly? I forgot to mention earlier that I purchased a seal kit of just O-Rings for this 140 Crosman Rifle maybe 5-6 years ago and resealed this Rifle back then and only shot it maybe 10 times to test it out afterwards. Got tired of pumping it up each time I wanted to shoot it. Didn't mind as a kid back in or around 1960 when my grandfather purchased this Rifle for me but at the time in my mid 60's then I just didn't feel like it anymore and put it back on my gun rack where it collected dust until the other day. I am 71 years old now. All and all this Rifle is in great shape. No rust. Blueing on the metal still in pretty nice shape. Wood Stock is nice also but with a few small chips. Thanks for making this video is all I want to tell you. You helped me revive my old 140 Crosman at least for the time being. I just want to Oil it with the Crosman Peloil when I receive it. Don't remember if I got any Crosman oil with the Rifle when I purchased it new. I believe back then I was using 3 and 1 oil on a rag just to wipe my Rifles down with and really nothing else maybe some WD40 also at times on a rag to wipe them down with.

Wow, that worked like a charm, only took a few hours to soak with 91% ISO... Saved me the hassle and time of a valve job.

Well,my dad's Benjamin is now fixed AND in under 10 minutes. I injected the alcohol and then just a touch of synthetic oil,gave er a few pumps and instant pressure building again. Running good and it's sat in the same spot for many years. Firing good. Thanks for this tip!!

Thanks for this great tip. Got my old Sheridan Blue Streak shooting again. Since trapping didn't work, now I can get the rabbit destroying my garden. Some say it won't last, but I just need a couple days.

Your help saved my Crosman 140, shoots like almost new thanks so much

Thanks for posting this tip and very good teaching style. I was given a crosmen 66 from the late 80’s by the serial # that didn’t pump. DOES NOW & holds air. Put some silicone oil in after several dry shots to remove the alcohol. Shoots great.

Thanks for the tip. I have a old crosman riffle about 23 years old I found in the storage attic dusty. I was gonna throw it away and came across this video, tried the flush and wow, it worked and shooting hard like it did before.

THANKS FOR SHARING YOUR KNOWLEDGE. I DID THE FLUSH ONE TIME AND NOW IT WORKS PERFECTLY...

Thankyou very much for this Excellent advice!!! I just did the alcohol flush over 3 days and saw little bits of string come out the barrel when dry firing and adding more 99% isopropyl alcohol into the air intake each day , and this morning my Benjamin 317(no serial #- made 1940-56) held air, and I chronographed it shooting 5.4 grain Crosman lead free "fast flight" pellets at nearly 700 fps, so I'd say that the alcohol flush was a success :)

Make sure you put some 3-in-1 oil or brake fluid in the same hole to lubricate the seals. Alcohol alone will dry the seals out causing them to dry out and turn brittle.

I put a drop in the oil hole and one on the push ring and one in the open chamber. I started with 1 pump then fired it with no pellet then 2 pumps and fired it then three and fired it ( air only ) and let it sit for 30 minutes then 5 pumps with a pellet then 8 ( that is max ) with a pellet and sweet I got my gun back - shot 5 pellets at 8 pumps and worked like it did when I first bought it , man sweet I almost sent it to its grave. - thanks for making this and the reviews help save my gun,

I didn’t believe it, but tried it and it worked! Just need to let it soak for a couple of days! Thanks!

I was cleaning out an old closet and ran across my father-in-law's old Benjamin 310 air rifle. There's no serial numbers or even a caliber marked on it anywhere, so I'm guessing pre 60's model. It hadn't been shot in decades and wasn't pumping up any air. I had been considering sending it out somewhere to get it repaired but ran across your channel and wanted to try your idea first. It took three nights of soaking but it's working again. A BIG thank you for sharing your knowledge with us. Will be checking out your other videos here.

The flush works. I flush on a regular basis now. Only a few drops is needed. Put a drop of oil on the cup at the same time. I get max pressure, max fps, and the gun holds full charge for days. Evidently manufacturers do not want you to know how to keep your air gun working for many years. $$$$.

My Sheridan has a leather seal on the pump, alcohol won’t hurt it. I have never done this because I always store it it with one pump of pressure. Mine is over 50 years old. I sent it in for rebuild about 1975. Still shoots great to this day. My Benjamin has leather seals on the pump also. I have had the pump seal get hard on it. I’m going to pull it out of storage and try alcohol.

My air gun I've shot and lubricated for years stopped working out of no where. It wouldn't pump any air at all, I put denatured alcohol into the system and pumped it to spread it around. After sitting for about 30 minutes it was back to life! It could probably use another soak and sit for a little longer. But im very thankful for this tip, I can't believe it worked.

I did just like you directed and it brought my Benjamin 392 back from the dead❗❗ Bought it at a pawn shop for $40 13 years ago when I was stationed in Fort Sam Houston, San Antonio, Texas! I let mine sit for a week. The previous owner or owners never did any maintenance on it other than oil the living daylights out of it. It didn't help either that I didn't know how to do any good maintenance on it myself. Ever since collecting 1377's, 1322's, crosman '130'.22, 2100's, 2200(needs seals or o-rings/a little bit worried about taking it apart/ looks like someone tried before), a daisy 880(needs seals or o-rings),312(when the trigger is pulled, a little bit of air shoots back at your face or eyes 👀), and a 392, I've been trying to learn from KZread videos and teaching myself how to take apart these airguns. Thanks for your video, I'd never would've figured it out since I haven't seen another video out there with this information. Again thank you ❗ Flushed out a lot of gunky oil, and bits of grit. Put a drop of peli-gun oil where needed and it's doing great ❗❗Now all I need is to find a video on the 2200,😁❗❗❗

Interesting technique! Looking at the video and comments it seems like it is working well

"Pumper that will not hold air" A drop of two of Pellgunoil on the pump cup will also do the trick, sometimes.

...When the alcohol evaporates it will dry the seals, so after the flush it's best to put Pellgun oil (or something similar) on the pump cup and into the compression tube as in regular maintenance....This will bring new life to the seals if they are not damaged in any way just by age.....Lubed up before any long time storage will also be a big benefit.........

You sure did teach me something about that alcohol thank you 👍🙏👌

I bought an old Blue Streak that had been sitting in a shed for years, through frigid MN winters and humid summers. It would not pump up when I got it. I did the alcohol flush and the gun pumped up fine and held air for days. I sold the gun to a buddy 7 years ago and it’s still pumping and holding air fine.

The 312 likely has a leather piston seal and a nylon check valve. Neats foot oil is the proper piston lubricant. Mac1 secret Sauce available from Mac1 airguns in California is the proper lube for all rubber sealed guns.

@NorthWestAirgun

Жыл бұрын

Agree on neetsfoot oil, or silicone oil, is best for leather seals. And maybe the earliest 312’s have a leather seal for the pump cup, but the vast majority are synthetic. So in that case, yes, secret sauce from Mac-1 is best.

Having worked as a mechanic for 20 years, when there were times a car had a slightly leaky fuel injector(or fuel rail) we would fill the car up with the worst/cheapest gasoline at whatever year it happened to be (used to always be ARCO gas but not sure anymore). And fill it with the highest octane rating (92 here in California) because it has such a high alcohol/ethanol percentage to achieve the octane rating on the shitty gas. This often fixed these smaller leaks because alcohol causes rubber to *swell* not because it was "cleaning out debris" so I'm a bit confused on your reasoning as to why the alcohol flush works. I do believe it works, and I plan on trying it myself on my benjamin 312. Perhaps both of our reasons are correct.

I never thought of that i tried transmission oil that didn't work, ill try it and let you it works

I did this with a 1322 that wouldn't pump up. . I poured in about a teaspoon of 91% alcohol and i shook it up and let the gun soak overnight. The next day i shook out all of the alcohol i could. Then i put some silicone oil in the pumping mechanism and a little in the Chamber . I pumped it a few times and it started holding air. I put more silicone in the mechanism every few days and it got better and better. Then i tried it in an old Crossman 140 thst wouldn't pump up. This gun pumps up but it's very weak. I think this one is going to get new seals So i am 1 for 2. That's not so bad for guns other people had given up on. Thanks for the video.

Just bought a crossman 1377 that's not pumping, gonna try this.

My Sheridan Silver Streak air rifle that that I've had since about 1970 was on the floor in our house when it flooded in 2017. I wiped it down and put it in the gun case and forgot about it. I tried to pump it up the other day, and nothing. I was watching the NorthWestAirgun video on rebuilding my gun when I saw a comment directing me to this video of their's on Alcohol Flush. Day one, no change at all. Second try I injected more alcohol and the following day the gun pumped up perfectly with no leak-off. Two more days later and it is still working the same. Thank you guys!!!

This worked on my crosman

Hi there, I have a Daisy 990 that used pump up just fine, until I took the part in front of the cylinder pump apart. I didn't sounds the same and seems a little weak in power on the pump side. The CO2 works great after new seals. My thoughts is that I put the check valve in wrong.

Very detailed video, thanks for doing that. I have a Benjamin 317 Air Rifle that belonged to my dad and it won't hold pressure anymore. I will try the alcohol flush this weekend. Would denatured alcohol work? Also if this doesn't work, can you reccomend a good relable source to buy repair parts? I found the original parts manual and don't think it will be of use since it was printed in the 60"s . Thanks for any advice, would like to restore this rifle. Mike

It's pretty hard to argue with the success you and others have had with the alcohol, but I'd be concerned because of the water that makes up any alcohol that is less than 100%, and that is virtually every type sold. If I remember correctly alcohol has a great affinity for water, and if it's not already there, any strong product probably absorbs alcohol from the air unless there's none to be had. If I tried it, I'd make sure the barrel isn't closed at the receiver end and work it hard the next day to remove as much of the alcohol as I could to avoid rust. On the positive side, most guns have lots of oil residue in them. FWIW, I recently bought a Crosman that absolutely had no indication that the there was a pump seal in it. I oiled it liberally (I only use synthetic motor oil), and the pump cup did respond and would pump up. With frequent use, it remains usable, but in time, it shrinks back to the point it will not hold the pump lever closed. Time for a replacement. Doug

Well, the Benjamins and Sheridans are brass, so rust is less of an issue, although some other rifles are not. But your point is a good one. Others have commented that they follow the alcohol with some kind of oil, like your non-detergent synthetic oil. Seems like a good idea to me. Wish I had included it in the video. Thanks for bringing this to peoples attention.

there are product s for a car engine to stop leaking ,by making the rubber seals soft again ,maybe it wil work in a sheridan to . by the way >>>bij putting alcohol under pressure with oxygen ,and at some point there is a change that you get the diesel effect inside the chamber .i would not pump more then once . and shoot it empty then .

Very nice informative video! I was recently given a sheridan silverstreak which has the hold down thumb safety. And after pumping it didn't seem to have much of a pop when firing it. I tried the 3 day alcohol trick and it seemed to make a difference. I put alcohol into the pump chamber on the second day and pumped it and the next day it still had pressure. Do you thunk maybe u should just replace the piston cup?

@NorthWestAirgun

Sure, the pump cup is cheap and is the best fix short of a valve rebuild. You can get them on ebay; www.ebay.com/itm/113531879648?hash=item1a6f0700e0:g:A5gAAOSwScdZxIDp and others offer them too. Get the tube as clean as you can before installing a new cup.

This process worked for mine about 2 years ago. Flushed out a ton of old gummy oil over a few days then keeping one or two pumps in the gun at all times kept it holding pressure and good to go for the two years. One day it was back to no pressure... Put in a couple ccs of alcohol and immediately went back to pumping fine so maybe it was some old goop that broke loose again and got caught up somewhere. Note: I never had and still don't have the issue with the pump rising from a back leak in the piston seal. Highly recommend this process to fix or even maintain a classic ridiculously accurate gun.

Haha, I know absolutely nothing about pellet/bb guns- I know nothing about any guns as I live in Canada and my parents wouldn’t allow; nor did we live in the right setting for anything more than a cap gun! ANYWAYS.. I now live on some acreage and my 10 year old asked for a pellet gun for his birthday. I bought an airmaster 77 off of my coworker. When I got home and tested it out, it wouldn’t pump even a whisper of air into the damn thing. I watched your video and decided I better try this alcohol flush before buying something new- but seeing that I don’t have any alcohol of that kind on hand; I simply blew into the pellet loading chamber (I’m probably butchering the terminology) and holy cow sh¡t it works!

I’ve heard of laying on hands as a cure, but never blowing into pellet loading chamber thingy. I’ll try that first next time. Cool you got it working.

Thank you for the information! I want to ask you if for the pumpers is OK to dry fire

Dry firing won't hurt anything.

Yes alcohol will clean the inside of the bore but Alcohol swells and destroys the rubber o-rings. You get compression because the o-rings are swelling but in short time dry out and become brittle and break apart. The correct fluid to use is brake fluid. Brake fluid cleans and preserves the rubber o-rings which make up your piston pump.

Automatic Transmission Sealant (Stop Leak) works well too and will not destroy the O-rings.

Brake Fluid is going to strip paint and maybe melt plastic. Use with caution. It can damage more then just the gun. I have no experience with the trans-stop leak, but it should be safer.

The seals will be fine if you also oil the cup. Over time oil and dirt fouls the check valve, gun leaks air. Flushing cleans out the compression chamber and allows fresh clean oil back in. Seals stay good. Use only air gun oil.

Thank you so much, you just saved me the look up, I’m a auto tech and I was thinking of trans fluid but brake fluid is definitely the correct answer.

Brake fluid is highly caustic. Rubbing alcohol is an extremely mild solvent. As long as you're not leaving the alcohol in and letting it evaporate before reapplying lubricant it should be harmless

Thank you!!!! It worked !!! (alcohol)

Gona give it a try, although, min stoped pumping becouse I was dry shooting I believe. Supposed to top off at 7 pumps. Ill check in later and let you all know. I also hear MarvellMysteri oil helps with O rings..may ad that later.

What do you think of pure Teflon as an Air Gun lubricant.Cheers fr Monterey, cal...

I hope you're still here. I have a 1377 that I purchased during the early 90s. I never maintained it. It recently stopped pumping so I dripped some silicone oil where I could and it's now pumping again. At 14:19 into your video: Mine, regardless of how many pumps, the pump handle will sag all the way back down. It will even sag down if I apply VERY little pumping pressure. Do I have more than a cup issue? Thanks you.

My dad has a benjamin model 317. It did not pump air or build pressure on his at all. It sat in the shed for years since it broke. Sunday I fixed it using baker air gun's seal kit and their tool for $60. Works fine now. So if this doesn't work, check that company out. Good luck👍 Edit* the video I used to help me was from this channel kzread.info/dash/bejne/iWWTpqmHkcSno5M.html

Jon, My 1969 Sheridan Blue Streak stopped pumping air so I did the alcohol flush like you suggested. It now holds air but it takes 8 pumps to get the same response as 5 pumps used to provide. I believe that the pump cup is old and deteriorated. It has the non-adjustable piston head, so I want to change to the Steroid Stainless Steel Piston Head, Jam Nut and Pump cup available from Mac1. Should I change the original aluminum front plug with the Steroid Blued Steel Front Plug from Mac1 while I am ordering parts from Tim and have the front end apart? Mark.

You can re-use the original front plug, up to a point. If a person drives the roll pins out and in repeatedly, the holes can become slightly enlarged and the pins can start to spin while pumping, eventually making the holes in the plug and even the tube get wallowed out. Try a fresh set of roll pins, then note where the split in the pins is, i.e., 12:00 or 6:00 or wherever. That way you’ll know if the pins start rotating and can swap out the front plug. It won’t hurt anything to replace it, just some people like to keep the gun as original as possible.

This is interesting. My friend has a mid 1960's Blue Streak that fires the pellet every other time. The in between times it bloops out the barrel. Do you think the alcohol flush will help?

Les, yes try it. Won't hurt anything, but might help. If it doesn't work, you are no worse off.

Merci beaucoup 👍

I tried it on my Crosman 20 cal c9a and the air still come out the barrel . thanks great video.

Mantap bang

I used silicone spray without knowing about the video and had similar results. It only stays strong for several months. I still want to change the rings.

The alcohol swells the rings so they seal the air better. This, I would imagine, is a temporary fix. Looks like it's time to replace the o-rings?

Do you have a video on how to replace the link spring on a 347 benjamin? It's the spring that holds the pump clised.

Hmm, I'll see what I can do. If you have one that needs fixing, send it in. nwa@northwestairguns.com

I have an old Crossman 140 .22 that I found in my house in a dark corner in the basement. I have no idea how long it had been down there. It is in very good condition had some slight rusting on the barrel and chamber slide. I sprayed some PB Blaster on a rag and wiped all the metal down. It worked well in taking off the rust. The stock is 99% original condition no dents or scratches. It would not pump up. So I did your alcohol recommendation. (I took a shot myself for good measure.(Not Isopropyl). It worked like a charm. I did inject a very small amount of hair clipper oil down the tube to keep the seals soft. I figured machine oil was a safer bet than motor oil. I am not familiar with air rifles. I am experienced with firearms. Can anyone give me the age and approximate value of this rifle?

Use silicone oil on air gun not petroleum based.

It worked on all 8 of my dads old BB guns
