Excellent Dan, I was going to say use a heat gun to help with removing the cylinder, it has worked for me in the past on some cylinders and cylinder heads.

Those phillips heads are not Phillips usually. They are JIS, with a proper JIS bit or driver they all come out with ease and JIS drivers works better on regular Phillips heads to.

Hi Dan I just pulled my 1996 Honda CB750 F2 top end apart and had the same problem with the cylinders stuck fast, My solution was to put a long flat plate with holes drilled out for the cylinder bolts to slide through across the centre where the cam chain runs. The I had a smaller plate the sat on top of the four centre studs with nuts on top to protect the threads this plate bolted to the long plate below and then installed the four 6mm bolts on the outer cam chain housing. Now I could tighten those 6mm bolts and pull the cylinder off the crankcase with a little help taping the lower corners of the cylinder to crankcase spots. No fin tapping

@@CafeRacerGarage Thanks mate it worked really good but don't put too much pressure on those 6mm bolts As you were saying the fins on the head and cylinders are very delicate

Great video Dan, I’m rebuilding an earlier DOHC CB750 over on my channel. I definitely recommend the plastic packers route. It really made light work of it, no need for an overhead “seesaw” or anything like that.

Fantastic video Dan. Looks like we were on point with the rattle issue:) Always love your work.

Thank you for the videos Dan.

My best tip is oil in the cylinder walls and rotating the engine. Then lift the cylinders and dead blow mallet tapping the block, sideways on the cylinder fins as you did, and the cylinder head studs (with nuts on top just to be sure) - worked well, quick and easy with every engine i have broken down so far 🙂

Thanks for the clear video!. The stuck barrels are a frequent issue with stripping down bike engines. The front of the engine gets sort of welded together because its exposed to rain dirt and moisture while riding. The piston ring friction does not help either. generally wide levers gently hammered in around the joint to gradually work the barrels off are what one usually has to resort to!

I split the engine apart on my 82 CB750 a couple years ago, but I may have a winter project as my new job may force me to go into the office a couple times a week and gas would be much cheaper for the bike than my SUV. So far the total cost of the bike might be $600 CAD, and I need to buy crank and connecting rod bearings. So in total, the bike might stand me $1000, because tires will need to be replaced too. It will be a fun ride back and forth.

Cheers Dan thats gonna give me a few pointers to look at as n when i pull mine apart . Brekkie was good worth the wait for your video. Thanks Dan

Thanx Gary. It’s still a long way to go to get it back together

I had the same Problems to bring off the head and Zylinder. Long time work for days

Good to see a teardown with cautions about breaking things. Also important to loosen the small bolts holding the head to cylinder block before loosening the main head nuts. The cylinder base gaskets on these engines are often baked onto the case and cylinder block. Your friends solution seems to have helped break that seal. There are alignment dowels at both joints, head to cylinders & cylinders to case, so it's important to pull these parts off without tipping. The alternator chain tensioner is probably automatic. The service manual should tell you more. Check the Technical Features section. Good Luck with the rest of your project!

Hello Dan you are doing a great job with you¨re videos and i really appreciate your hard work . I just want to tell you that the problem of the alternator chain tensioner is that little spring ( 9:47 ) ... look a it very well and you will see that is out of his place. i am doing the reconstrucion of the engine of a 1993 model and i have dissassembled the engine for that spring failure. I have modified the tensioner and now i am sure is lifetime warranty. Regards and congratulations for youre hard work and good quality videos. CHEERS...

Yeah him pushing down on the tensioner runner should be causing the tensioner unit to ratchet ahead and it is not doing that , its def seized up !

10:05 "i've got a couple options" ... I was thinking it would have been possible to to have left the head on , flipped the motor , pulled the lower case , pulled the crank , replaced the chains and lower tensioner and put the whole thing back together , just saying on a low budget scenario this might be a possibility eh ??

A trick to removing the cylinder is to rotate the crankshaft by hand and put the penetrating oil in the cylinder. Then bring all the pistons to the same halfway point, then try tapping the cylinder off

any idea what pitch and length the alt chain is?

Cylinderhead Stays r generally a pain in the a** at older naked Honda Multicylinder bikes... they tend to gunk with sand and dirt at the front side. Well, mayb it just sticks out at Hondas since they are the pretty much only ones running inline fours/six after like 40 years. 😉

Hi, I live Australia and I think you do also? My question is how many kilometres had the bike done before you pulled the engine apart?, also were the piston bores within specification? I am just about to watch part two

@@CafeRacerGarage Ok, thanks, I'm actually watching part 2 as you sent your reply

Camchain, camchain tensioner, camchain slipper, alternator chain, alternator chain tensioner....the usual Honda issues😎

If you can source some cams from a CBX 750 F you can get more performance out of it, the engines are practically the same bar some minor improvements on the later engine. Currently have to pull my CBX 750 engine apart as I have some major vibrations coming through from the engine at about 3500-4000 rpm so this is quite handy to know how to take it apart. Also those chain tensioners were a common fail point in the CBX's so not to surprised they failed on the CB750, seems the automatic chain tensioner seized a bit and won't ratchet forward. A good source of info as well is fj1200.info the owner of the site has some good writeups on the CBX 750 and those chain tensioners.

I thought he was working on a CBX 750 variant to start with ? His is the sprocket main drive output version of that engine, so his crank drives the tranny with a gear where the earlier CB's drove the tranny with a chain , or i have i got this mixed up ?

Well done, seems like you found the reason for the rattle 😊 I can see you are doing one thing wrong: you are using a hammer on your ratchet to loosen bolts 😮 You should use a breaker bar first, most kits include one. I do the same all the time, and I have destroyed a couple of ratchets because of the misuse 🥴 I have a lot of unused breaker bars though, If you need one 😁

Yes

those screws are JIS and chances are about 100% someone tried to undo them with a Philips driver, and then ruin them. you can safely replace them by allen screws but not stainless, that will oxidize itself stuck into the aluminium

So at this point here 8:00 with the oil pan off , is there any access to the alternator chain slack adjuster ? Can it be inspected here like if the engine was still in the bike ? On my motor i removed the alternator cover and grabbed the alternator fan and was able to rotate the shaft back and forth and assess whether there was very much backlash, i found there to there to be very little backlash and no shaft radial or axial movement . So now i'm thinking my noise source may be the timing chain ? Anybody else here been there done that ?

At first i though i was watching Guga food based on the background music.

It’s the cylinder block not the cylinder head....
