Clutch push rod

[Shay HTFC]

I'm just wondering about my clutch.
The clutch arm (you know where the cable attaches to on the outside and passes the force inside the crank case) just feels dead.

I took off the cover and I can see the push rod going into the centre of the thrust plate and clutch springs. Now this seems extremely difficult to push in and having replaced the cover making sure that the push rod gets seated with the clutch arm 'pusher in bit', it still seems to be not budging.

How do I know if the pushrod is in its 'in' or 'out' position? How can I tell if its already pushed as far in as its supposed to go? Should that push rod simply be able to push in to disengage the clutch?

P.S. Its a 1989 CG125 engine

Sorry for the double post, but I thought I'd bump this with a photo of the clutch as it is.

Is it possible to tell from that photo if the clutch is sticking or whatnot? I am assuming that the push rod should be pushed 'into' the clutch to disengage it?
Is it possible that the thrust plate is not out as far as it should be and the clutch plates are locked together and sticking?

Yes, when you pull the lever it moves the worm gear, which moves apart as it twists. Which in turn pushes the rod, which compresses the clutch springs and separates the plates.

I would suspect your springs are knackered. They do compress over time. Did this happen suddenly or over a while?

I was given it and its not been ridden yet (by me anyway)
I had it in the frame running, but the bike would just stall when changing gear.

Should the thrust plate be further out if it was normal? I put a screwdriver between the plates to try and separate them (as I read on Dansmc.com) and the thrust plate had what looked like a tendency to go into the basket as if being pushed by the push rod if you get what I mean?

I'm wondering if the plates are sticking? (or maybe the springs are just worn out, but I'd have thought with worn out springs the clutch would just feel loose rather than immovable, right?)

Is there a way to test if the plates are sticking without having to put it in the bike and try and bump start it, then pull in the clutch etc and force them apart that way?

No, when the springs wear out they get shorter. It's unusual though, I'd suspect a knackered worm drive, although sticking together plates is definitely possible.

Get em out, separate em, chuck em back in. Job done.

Oil em before you chuck em back in.

aye tis best to let em soak up some nice clean oil. and get some new springs for that new feeling, it makes alot of difference from my experience.

Here's a daft question. Those 4 bolts around the pushrod. They are torqued down hard, aren't they?

as said before its probably sticking plates, to get them out you need a peg spanner on the oil pump (that lump next to the clutch basket) then you can take the plate off and get the springs and plates out.

id recomend giving it an oil change and pump the clutch with the engine running to free if off if you dont want to get into the basket. same situation happened to me on a z250 and a cb250rs and the way i solved it over time was just to keep trying to use it and eventually it will wake up.

Cheers
