Struggling with clutch adjustment

(1/3) > >>

andy120t:
I'm in the garage trying to adjust the clutch. As a starting point, can anyone tell me .. should all the 4 bolts that hold the clutch / basket be fully screwed in?   I've been searching round for inspiration and I think they should be, but when they are I can't disengage the engine/ drive chain.

It seems unlikely that the push rod is too short, and I'm out of adjustment on the lever / cable so I assume my setup is wrong somewhere. Only options i rethink of are that the bolts have pushed the whole lot in too far, or maybe I have the wrong cable with too much freeplay/cable.

Any thoughts appreciated!

I'm pretty sure the clutch basket springs should be torqued up. Not sure what your model has in terms of the mechanical system that converts the cable pull into depressing the clutch the 400 has this triple balled plate system. Then if course there might be the thrust movement between the basket & the gearbox shaft. Others here will advise I'm sure.

Bryanj:
Cant tell you how to adjust it till you tell us what bike, and model, it is

High Andy.

Assuming you have a 550, as that’s the forum section this appears in, all four screws should be tightened down to the specified torque. Are you sure the clutch housing lever is on the correct side of the lever mechanism. If the bike has been stripped down it’s easy to over extend the lever and have it flop to the wrong side of the operating mechanism in the housing. That’s only one possible cause of course.

Thanks for the thoughts....model is a 550F2. 

The mechanism inside has been set up so it doesn't flop about - and the cam stays behind the actuating arm and is pushed back into place when the clutch lever is released, so I'm sure

I'll dig out the torque settings and check those.

Cable is new and I can't find a receipt but I'm sure it's right but if not and it's too long, potentially could that mean it doesn't disengage enough.

Plus it's an old clutch so could the plates be too thin..but then it would slip rather than grip...

I'll check the torque first and report back.
