360 clutch slip high rpm
« on: Aug 30, 2011, 15:13:52 »
So I finally rode my cj360 other day and the clutch seems to slip at high rpm. Clutch grabs and seems strong at low rpm. I have adjusted it per service manual. I had about 1/4" of cable play and it didn't want to engage all the way so I tightened it a little more at lever seems fine just not at high rpm. Is it time for a new clutch?

ha! i was just dealing with this on my cj...but the cable seemed to have fixed the problem.  if you have to replace the plates and springs...its pretty cheap.  Good luck--sorry for no further insight, lol. 
so a dolphin is driving and his car breaks down...he takes it to a mechanic...the mechanic says its going to be a few hours if he wants to wander around the town...upon his return, the mechanic says "looks like you blew a seal" to which the dolphin replies: "no sir, it was a walrus"

I have exactly the same problem with my 378 motors, this is cheapest fix
Get a set of heavy duty clutch springs from Bore-Tech
They are about $15.00

make sure the clutch lifter is adjusted properly.  You can try bead blasting the plates too.  I've had great results doing this and without resorting heavy springs.  I bought a Kawasaki H2 with heavy springs and the heavy pull got old quick...

Double-check your adjustment.  Play (measured at the end of the clutch lever) should be about 1/2" before getting tight.

I re adjusted it today if I have a 1/2" of play at cable it barely pulls lever. I'm thinking that this lever isn't pulling enough cause when I have it adjusted with 1/2" play and I put it in gear it drops idle down then stalls. I have tried adjusting it numerous times. My clutch lever is just a universal lever. Any ideas?

So i think i have two problems.
1. the clutch lever dosn't have enough throw to fully disengage clutch.
2. clutch slips when i really get on throttle.

anyone have any recommendations for clutch lever? also i have clubman bars, and a promotion cable, and universal cable.

I don't know anything about 360s apart from a motor hiding in my shop somewhere. The big issue I read about is trying to adjust the cable end when the problem lies in the left side cover.  That lifter arrangement has to have sufficient free play but not too much.

The technique is to loosen the cable adjusters right off and then adjust the lift adjuster screw and then take up surplus slack in the cable.
