    Slash 5 Flywheel removal

    The bike: 1972 R75/5 about 55,000 miles, parked for many many years, getting a once over before moving to the category of "rider". I'm pulling the flywheel to inspect and replace the rear main seal as well as the oil pump O ring. Removed the 5 bolts in flywheel and she is stuck! I don't want to use a puller as that might push the crank forward, it is blocked but does not seem worth the risk. I thought of using a dead blow hammer attached to a bolt screwed into the wheel. So, I am looking for suggestions on the safe removal of the flywheel.
    Thanks!

    heat with a torch is a pretty standard method and then it pretty much pulls right off......The same thing for re-install........God bless......Dennis

    Flywheel removal

    I use a piece of 1/4 in. bar stock that's long enough to cross the bell housing. Drill a couple holes opposite holes that hold on the clutch assembly, and use two of the clutch removal bolts to pull it off. Don't need heat, just patience.

    Sucess!

    Used the combo of your statements to release the flywheel (with no damage to any surrounding parts or humans). Finally was able to use my 18mm Craftsman combination wrench, it has hung up for years and never got any action, living between the highly used 17mm and sometimes used 19mm, it was a forgotten wrench. Used the clutch removal bolts to hold the 18mm across the flywheel, then a bit of heat, not too much, and a dead blow hammer attached to the 18mm wrench, a couple of hard hits on the dead blow shaft and the flywheel pulled loose. Not much oil leakage. After 40 years I would expect the seal to be nearing the end of it's job of keeping oil on the inside! Any bike that has low miles typically has sat for extended periods and that allows the seal to dry out, that spells leak. The seal is not cheap, about $26 bucks, but why risk a mess on your clutch plate? I see these really nice looking bikes with low miles go for fairly high sums and note in the descriptions all the seller did was freshen up the fluids and gosh, it runs great! Just wait. While the job is a bit labor intensive, it is rewarding. Plus you have the chance to clean stuff up like the swingarm bearings.
    Next step is a lightened flywheel!

    Lightened Flywheel

    I have a slash flywheel already machined and ready to install, I am also doing a 1974 R90/6 so I had the machine shop do the same on that wheel. They look pretty cool.

    Cleaned her up a bit

    I was lucky that the grease was fairly light, a scotch brite pad and cleaning solution made fairly quite work of it. Seal came out and now I will sit and look for the Postman to come down the street with my new rear main seal, oil pump O ring, flywheel bolts and clutch cover allens. I order stuff from Hucky's and he is really quick about getting stuff out. So while I am waiting I will pull the seals from the swingarm and clean and re-grease the swingarm bearings then install new grease seals. Fun stuff!
