Clutch won't engage after putting in new springs (cb77)

Hey all, I have a quick question, if I have a five plate clutch assy, and I put new clutch springs in that are the short sprigs meant for a different year assy, would this explain why my clutch won't engage at all ?

Either something is keeping the plates apart, or the springs aren't pushing them together. Could be the springs are too short, but I would think it would still engage and slip a lot. Make sure you adjust the actuator on the right side cover so there's some play.

Hey thanks for the reply!

I pulled apart the clutch and I guess the plates closest to the engine, behind the springs had seized, I got them out and lapped them, put back in the original springs and it seems to be working pretty good but it will only engage when adjust so it's pretty hard to pull. Wish I could fix that, not sure how.

I'm unclear how any adjustment could make the pull easier or harder. No matter how the cable or thread is adjusted, you are just pulling against the force of the springs, right?

It makes a big difference in the lever pull how the clutch is adjusted. Pull the right side cover off some time, with the clutch cable still attached, and pull the clutch lever while watching the lower end of the cable. If the cable forms a 90° angle with the arm on the clutch lifter, you will have the easiest pull(ideal mechanica advantage). If the cable is adjusted out until the arm and the end of the cable are nearly a straight line the clutch will be really hard to pull. In other words, when you adjust the clutch you always back off both cable adjusters then adjust the clutch lifter screw (tight, then backed off a little for running clearance)first and adjust the cable slack last.

And don't assume because you have 5 plates when you open it, thats the RIGHT number.

Mine had the wrong number that the PO stuck in there, and I couldn't figure it out until I got on the phone with LM and worked it out.

I would have never realized someone put the wrong number in there.
