I purchased a "non-running" Generac XP8000E with only 13 hours from new. James, thanks to this video I went directly to the cause. Got it on the heel of the cam and used a soft hammer and a long screwdriver and BINGO! Changed it onto 5/30 Synthetic oil and it runs like a charm. You are truly appreciated Sir! Thank you!

Jim, Your videos have inspired me. Yesterday I picked up a Honeywell 5500 generator (very similar to the Generac line). It was advertised as non-running, needing a new carburetor, and making a ticking noise. I picked it up for $70 and just happened to have a correct donor carburetor for parts. Following your lead I was able to get it running well and producing power. Thank you for sharing your significant knowledge and experience. Cheers.

You’re quite there surgeon! I’ve never watched an entire surgery on a generator, although I’ve participated in many surgeries. I wish I had you nearby, as I’ve got a Generac that developed an undiagnosed problem, plus now it’s seized. One thing in humans, you can deliver meds to counteract the problem....not so in a generator (except carburetor cleaner). I’m in a County where it’s actually not safe to trust anyone claiming they are a mechanic it have fixed the problem before. Often you end up on the losing end of the stick...First is usually the theft of your parts, second they couldn’t find the problem but you owe them for time and labor, or there is no such business ...and they said they pick up and deliver. If there is a criminal venture, it’s going on in Northern California small counties!

Great Video. I Have an old Generac 12 Kw stand by generator. Motor will turn over but won't start. Turns out number 2 cylinder has a broken intake push rod. Took the head off and it too has a stuck tappet. In the up position. Just touched it with a hammer, dropped right in. I'll let it soak in some upper combustion cleaner. It's an old unit but came from an estate with regular maintenance. Oil is perfect. I saw your video a while ago and had to go back and watch again. You are more ambitious than I. Don't really want to take this whole thing apart. It's almost 20 years old. Just get it running.

Wow! I learned something new. Based on what you went through for the rotor/stator tear-down, when I run across a stuck tappet, I am going to soak it in penetrating oil and see if it frees up before ripping everything apart. Hindsight is 2020 but foresight is 2022!

You are a heck of a good troubleshooter

18:06 Been binge watching your videos and this is the second I've seen where you have a 3/8 thread and don't wanna mess up the threads (use water/oil to compress). I've encountered similar and while I don't know if it'll work for this, this is how I solved the problem..... cut the head off the longest bolt (3/8 here), cut a slot in the bolt where the head used to be. This will allow you to use a long screwdriver to thread it into the output shaft. Once that bottomed out, use another rod and bolt to push against that. Since it's fully threaded into the shaft, its "threads safe". Used this method on lawn equipment years ago as a golf course mechanic where flipping a 3 ton mower on it's nose or cart on it's side wasn't an option. Like your approach, but figured I'd mention an alternative that's got less clean up.....

The water method works great for a snowmobile clutch with no puller as well. Same problem, it’s difficult to get the clutch in the proper orientation for the water method to work.

There is no valve stem cap on the intake valve for hondas and honda clones. It's only needed for the exhaust valve, presumably due to thermal expansion. You can tell by the fact that there isn't any space for it on the intake valve spring retainer.

Hi there! Excellent video. Hard and good work. I think that something else must have happened to your generator. I don't think it's was just due to a bad oil. Let me explain why I believe it. I have a new Generac GP5500 generator. It only has 8 hours of use with the same oil that came from factory. After these 8 hours (first use), it did not start again. The spark, in the spark plug, was perfect. I perfectly cleaned the carburetor but it still didn't start. Then I disassembled the valve cover and found the problem. The pushrod of the intake valve was laying free on the bottom. It was released because the valve was sticky and did not return at the same time/speed as the pushrod. It did not maintain a constant pressure or contact between the components (valve, rocker arm and pushrod). This caused that, even if the valve clearance was eliminated or fully tightened (adjusted to .00 mm or with no gap for testing), the pushrod it would fall off when the engine was turned. I solved this problem with a few drops of lubricant, which did it immediately. Now the engine start at the first pull, as it was. But I'm afraid it will happen again. It makes no sense that this has happened to such a new generator. I do not think it is a coincidence that this has happened in the mechanism of the intake valve as it happened with your generator. It will surely happen again and the same work will have to be done; also in your generator that, in your case, require much more work. I fear that it is due to a condition of poor lubrication (bad irrigation and/or oil pressure), or/and a poor desing and/or poor finish of these intake valve components, including the cylinder head, in some models of this brand. Maybe the gasoline is affecting it? Friction? Temperature? Materials? Parts? Other? Any other idea of what really caused this problem? Suggestions? I need to be able to trust this generator as reliable. I really appreciate it. Thank you!

Carl Luciani judging by some of the comments this seems to be a fairly common problem with these engines. In my case the tacky oil was enough to to cause things to bind up. Before turning the camera on I tried soaking the area in WD40 and later carburetor cleaner. Neither made any difference. Was expecting to see something broken inside. Would guess that the tolerance of the lifter hole is too tight or the lifter diameter a little too wide. Would think putting some hours on it will help. Otherwise maybe running it with a lighter weight oil like 5w-30 might help. The only way to solve the issue for sure is to bring the lifters to a machine shop and have them remove a little material so the fit is not so tight.

I'm repairing an ETQ TG52T42 generator. The thing only has 50 hours on it and I take good care of it but when I was starting it up for the winter, it ran for about 20 seconds, and then all hell broke loose. I diagnosed the issue. Turns out the intake valve seems to have become detached from the valve spring retainer, causing the piston to slam right into it, bending it as well as damaging the head. After replacing the head, valve, and retainer I ALSO noticed that not only did the intake have no valve rotator cap (as you're seeing with your Generac) but only the exhaust has a valve down spring retainer. Now I'm trying to get an answer to why that is seeing that other engines, like Briggs and Stratton, do have these for both valves. Also, this is the last time I buy a Chinese engine. It isn't easy getting parts for these things.

@@jcondon1 Yep. I have no problems fixing these things but I need to source parts somewhat locally. All of the parts I had to order were only available from Great Britain, adding shipping cost and time. While putting it back together I noticed I needed a gasket and pushrod. I ended up making the gasket. The pushrod was only $10 but $30 after shipping so since it was just a smidge bent, I carefully straightened it back out. These are parts I would normally just buy but that sticker shock makes you get creative.

I’m wondering if the oil had some form of sugar in it from the nut residue? That would / could result in the sticky cam follower.

If you look at the two tappets, the one that was stuck it's definitely a darker color. I'm wondering if that chunks of acorn somehow got crushed up into a powder was spread around by the oiling system, and created a bit of friction on that tappet. I definitely think I would spend some time decreasing the entire insides making sure it's completely clean and then re-lube it before reassembling it. What a very odd odd failure. I agree with you also not really being able to think how a piece of acorn could possibly get in the engine in the first place. Perhaps at some point somebody left the oil fill cap off and the critter dropped or even went down inside there. Considering you found acorns in the oil that's really the only explanation I can come up with. also I wonder with such short amount of run time, maybe the contamination occurred even at the factory when it was assembled. Maybe the engine blocks sat unattended for a while before being put together and someone didn't notice the junk in the bottom of the engine block before putting it together. It certainly would take a while for that acorn to get crushed up once the engine was running. One other thing I wonder is why the owner didn't have it repaired under warranty. With such short hours. unless of course he owned it for several years and just didn't use it much.

James, When adjusting valves, do you use the TDC with the intake open, then when exhaust open or technique when at the compression stroke both valves are free then adjust?

I adjust at TDC on the compression stroke (both valves closed). But it does not really matter. When one valve is all the way open, you can adjust the other. The problem with TDC is that it is there twice, once when ending the compression stroke and again at the ending of the exhaust stroke. A lot of people do not realize that and adjust the valves wrong.

Do I understand you that the rotator cap is stuck in the spring? It is possible to remove the valve spring without taking the engine apart, but care must be taken so the valve does not fall into the cylinder otherwise you will need to remove the head. Remove the spark plug and rotate the engine to top dead center of the compression stroke. The piston at the top of the cylinder should keep the valve from dropping all the way into the cylinder. You can now remove the valve spring. NOTE: the valve will drop down some making reinstalling the spring and spring retainer difficult. To minimize the valve drop you can add a little rope to the cylinder before rotating the engine to TDC. Then when at TDC the rope should fill the rest of the space and the valve will drop very little when the spring is removed.

I like to watch the” water boarding” rotor extraction technique. Pop that rotor. The rotor shoot off because of trapped air in hydraulic. On top of that I also saw you replace water with blank rod, and the pry bar plus few blows of a rubber mallet at the side of rotor. Let me add few more for options. 1) Nail gun firing blank into the hollow shaft, pneumatic, no need of - PTFE tape or sealing. Best result - pretension the rotor outward and engine rear wards. 2) prepare a spare stock retaining bolt, be headed by (0.5~1 inch), add a slot at the blank side, drive it into the engine shaft through rotor shaft, full threads. Add compression behind the modified stock bolt by a second bolt. To see that rotor pop off. 3) keep the same bolt in the rotor shaft, but unwind it 1 to 2 turns. Pretension the rotor outwards and engine backwards. Use iron mallet to drive the rotor shaft bolt at bolt head. Suspend the crank case on a piece of plank first.

THOMAS DRELICH Fuel and spark are the most common problems. If you have not already, try some starter fluid. If nothing, then double check spark. Verify you see spark on the plug. Also note, if the coil is mounted backwards it might produce a weak spark, but no spark when under compression. If you are sure you have spark and fuel, then you are left with compression and timing. The flywheel has a key that could be sheared. That would throw the timing off, but that would be unusually for a generator. A sheared key is much more common on a lawn mower after hitting a rock. Compression can be hard to test because most generators have a compression release built in, so even with a healthy engine, you probably will not get above 60 psi on the compression gauge. Generally, a healthy engine should be 100+ psi without a compression release. Did you check the valve clearance? Potentiality a value is not closing all the way either due to a clearance issue or not seating correctly on the head. Could also be a blown head gasket. That happens most from over-heating caused by the cooling fins being clogged with a debris. If not the values or head gasket, then you are looking at a piston or cylinder issue. Or the internal timing may have jumped between the crank and cam shaft (rare). Before taking the head off, you should get a cheap compression tester and check the numbers.

better than eden off-grid homestead I removed the spark plug and turned the engine until the piston was at the bottom of its stroke. Then got a rope and feed it down the spark plug hole. Once enough rope is in there try again. If you put enough rope in, the piston cannot reach the top and you will be able to turn the bolt out. Rope works well, but need good clean rope that you know will not break off in the cylinder. Also you can order something called a piston stop. You screw it into the spark plug hole and it will contact the piston holding the engine still when rotated.

I recommend a trickle charger the one that comes with it does not stop charging when the battery is full so you could end up ruining your battery. Just make sure the polarity is correct.

When removing the rotor, what about using the rod by turning the end down smaller than the threads so the end would not impact the threads?

That would also work, but have bent a couple larger rods. A smaller might not be enough.

I have a question, what is the valve lash setting?

I have this same one and today (we had a hurricane last night) it was running fine and died. I checked oil and it was a little low so instead of just adding some I changed it. Started right up and then within a minute a big BANG backfire and puff of smoke out the exhaust and now no start. Now it will backfire out or the carb but not start. 80psi compression and I adjusted the valves and checked timing on the magnet with TDC. Pulled the cylinder head and the valves are closing fine. Seems the timing is off, but the key in the flywheel is fine. Ideas?

Eric Earhart it’s acting like the exhaust valve is not opening. Did you pull the head or just the valve cover? For timing when the piston is at the top of the compression stroke, both valves should be closed and the magnet just clearing the coil.

@@jcondon1 I pulled the head and cleaned the top of the piston and the combustion chamber. I agree with the exhaust valve diagnosis. While slowly turning the flywheel and watching the valves the exhaust valve doesn't close till exactly TDC, the engine is firing several degrees BTDC. Conversely the intake valve is fully closed as the magnet begins to meet the coil. I thought I was observing the compression release effect?

Great job, thank you. But somewhere in video a little bit shorter. Alternator end connection you don't show. You fast pass this part and also torques of bolts. You can explain in the video armatur bolts, engine crank case bolts etc. How many torques needs this bolts. İf you do this in the video with writing subtitle, it will be more benefit to us. Because we can't find these torque values and these values are very important for engine repairing. Again thank you so much. Sory for my poor English. Waiting for new generator videos with excitedly. Have nice days :))

Özgür Demirtaş I could not find the exact torque values which is why I did not cover them in the video. Before removing the bolts I used a torque wrench to find the torque where the bolt started to move and used that value when reinstalling. I think the main center bolt was around 35 ft lbs. the stator bolts I do not remember, but think it was around 20 ft lbs. I recommend calling Generac for the exact values.

The statue bolts are a lot smaller. 20 ft lbs might be too high.

If the exhaust is not moving much that either expedite valve clearance or more likely a worn camshaft. These are know to have camshaft issues.

That was bizarre. Not knowing the cause for certain would drive me up the wall. You said 'service manual'. Are there manuals for trained mechanics that are far more detailed than 'operator's manuals', like with cars? Would love to know how to find them. Keep up the great work!

Your video was great, thank you, my problem is a little different and I was wondering if you have any ideas of what you might think my problem is. I have a Wen Power Pro 9000 and it was running great. Here is what happened I have two generators and I usually crank them up about once a month and let them run for about 15 minutes, well about a month ago I did just that, well while the 9000 was running I was jacking with the govener (sp) and the engine would speed up then it would slow down, all of a sudden while I was doing that the engine stopped and ever since then it won't start, I have check the spark it's good, the gas flow good, the oil level good, I've even disconnected the oil switch and nothing, when I put my hand over the carb I get backfire through the carb, it pops and snorts and farts but it will not run I pulled off the cover for the rockers and they and the pushrods seem to be working fine....any suggestions?

I would remove the airbox cover and filter. Look through the carburetor and make sure the throttle plate is full open (when engine is off). Potentially the governor spring broke or came disconnected like what happened in this video kzread.info/dash/bejne/qqCntqycetu6odo.html Otherwise would consider timing or compression, but would find that unlikely based on your description.

How do valves get lubrication in these engines ?

Thanks ..take my advice and idle down your Generac genarator before shutting it off at full throttle..all that popping and back fire bent generacs cheap push rod out of the rocker arm ball socket...replace with hardened push rods if you can find a set ..otherwise a flat surface and lighty tap the bent push rod with a hammer no problem..but expect it to happen again

Hi James been watching your videos and because of your thorough explanation of every step I was not to worried about purchasing a generac GP7500E. This would of been a great one for you that someone had already attempted to repair. It to has a stuck tappet on the exhaust side but down not up unfortunately Im thing the cam lobe will be toast when I get her open. Is there a repair manual that you aware of with torque specs for this machine? And do you know the thread on the end of the Armature?

Glad to hear. Also found the service manual that I used for the GP series. Oddly enough I do not think it includes the GP7500e, but would think the torque specs are probably the same on the GP6500. drive.google.com/file/d/1HRNFPDSgwufAEjqyFJrgbFnEkbUOSr_8/view?usp=sharing

what could be the possible issue when the valves are moving but the cylinder head gets pushed all up, and never gets down? still can be rotated...

What I do for everything I own, . even my truck and car is add the required amount of MARVEL MYSTERY OIL to my gasoline. Lots of people laugh and say why waste your money? My money and my peace of mind. Years ago, the EPA ordered all lead to be removed from gasoline. What the lead did was help lube the upper cylinder of the motor. This stuff helps with lubing

I have a Powerhorse 9000 generator in my shop. It won’t run. When you turn it over, after a few tries, it backfires out of the carb. Is it possible for the cam and crank gears to jump a tooth and get out of time? Here’s what I’ve done so far. Cylinder leak down test, it passed. Checked spark, spark will jump 1/4 inch. Rocker arms adjusted to spec and operating properly. Removed valve springs and made sure valves aren’t sticking. Removed muffler and made sure it’s not clogged. Pulled flywheel and checked key, it’s good. Checked ignition coil gap. Carb is spotless and working. Clean gas tank and fresh gas. The only thing left would be the timing between the cam and crank.

You can check the valve timing by rotating to top dead center on the exhaust stroke. In that position rock the engine back and forth. You should see valve overlap. Exhaust closing and intake opening. At tdc of the exhaust stroke both valves should be open a little if valve timing is good. If good then would look at replacing the plug or maybe the coil. These engines spark twice. Once on tdc of the compression stroke and again on tdc of the exhaust stroke when both valves are open. Potentially you are only getting ignition on the waste spark during valve overlap?

@@jcondon1 Just tried what you said. At TDC of the exhaust stroke both valves are just slightly open. I used a cylinder leak down test to confirm. So I’m going to order a new ignition coil. After all the time I’ve spent working on this thing, if it turns out to just be a bad coil, I’m gonna throw myself into a volcano. Lol. I’ll let you know how it goes.
