hi, having a bit of a nightmare...

'89 998 BRG, Non-verto

 

Gear changing started to get very crunchy recently, got to the point that it woudnt engage.

So I took off the housing, and found this..

So changed it, did the slave cylinder/piston/release lever while I was there, as it was leaking.

Thought that would have sorted it,

But it still wont engage.

Clutch release lever operating ok, throw out stop, adjusted ok.

 

One symptom...The engine revs lower when depreesing the clutch...why would that happen?

Does this mean there are more fundamental problems?

Do I need to change the flywheel?(dont fancy that job)

 

Apprecite any advice

I've a feeling your primary gear bushes are worn. Did you check it whilst the clutch was out?

no I didnt, just took the housing off

Is that a difficult job?

Depends if your crank is badly scored first. I'll wait until nick or spider moke have had a say first, as I could be wrong.

Does sound like either the thrust washers are worn, or the primary gear catching the crank nose

thanks, thought it might be serious....Thats too big a job for me, so its off to Thomas Classics in Cwmbran

I really do hope it isn't what I've posted above, but it's highly likely

It does sound like the Clutch maybe over-throwing.

 

How many revs drop when the clutch is depressed?

 

As Steve mentioned, it maybe a Primary Gear issue, you'd take the Flywheel & Clutch out to check.

it was idling at about 1200, dropped to about 800 when clutch engaged

 

I dont have the facilities to take the engine out, so have asked a local mini expert to help get her better
