More clutch questions
My clutch lever on the 78 shovel is super tough to pull. Did a clutch tune today and could never get it to disengage unless there is absolutely no freeplay and even then it still drags a little. I really had to fiddle with it to get it to where i could find N, still need to be rolling to get it out of gear. New friction plates, the steels are straight and I think the releasing disc is in need of being replaced, it has grooves in it and is probably warped. Anyway i can live with it the way it is but I would like it to pull easier. Any ideas? Thanks!
You say you have a '78. That should be a ratchet top. The cowpatty top is simular. Sounds like you need to start from the top and work down. At the handlebar, do you have those nylon bushings where the pin slips in? Is it lubricated properly? Have you taken the cable off and lubed it? Is it stretched. You may just want to replace it to make sure. Buy a good American made cable. The cheap chinese cables streatch alot and make your clutch unpredictable.
Get your FACTORY shop manual out. Open up the kicker cover and see if the throwout bearing is shot. Replace if needed. Replace the bushing on the verticle shaft going into the kicker cover. Check the setting on the clutch lever arm VS the starter motor, I think it is 13/16" clearance. Pull your plates out and give them a good cleaning ( I always liked to hit them lightly with a sand blaster to ruff them up). Are the slots in the steel plates mushroomed? Are the holes in the fibers OK? Slip each one over the hub to see if it moves freely. Look at the hub. Are the studs clean and not grooved. If they are, replace the hub. Clean the inside of the clutch basket also. Look at your pushrod to see if the end of it is mushroomed, replace it if it is. Is the ballbearing in the adjustment screw?
Put it all back together and adjust according to the manual. The hardest part is adjusting the springs. It takes a little time and patience. Don't take it out and haze the plates, or you will have to take it apart and reclean them.
Others may chime in with more info, but it just comes down to good maintenence. You may want to consider a Tamer. They do what they advertise, and stabilize the whole clutch system.
