Classic clutch failure

Dalvikingur · Oct 17, 2018

My clutch was stuck and no surprise the pivot was pushed through release lever.
I have bought a clutch fork kit with nylon bush from britrest (http://britrest.com/my-heavy-duty-clutch-fork).
Since the pivot went all the way through I do not have any means of centering the drill for the bush. Could anyone please supply this? There must be a clutch fork lying around in a garage somewhere.

I was thinking as shown on the attached picture but anything goes as long as I get a pretty accurate point for the center of the pivotball bulge (or whatever it's called).

I actually bought a new pivot but realized it was 40mm long and my old one is 58mm. It seems the only pivot for sale I can find is 40mm (FTC4173)!? Any ideas?

I have to agree with this, this is what I have used although I made mine myslef by welding a heavy gauge steel to the back of a normal release fork. Although the nylon bush idea sounds good in principle I would still expect this to wear and eventually fail in the same way (any one who has used polybush suspension parts will tell you that).
I would also fully agree with @jamesmartin regardin the pivot. If you are fitting a nylon bush I would definitely replace it. Mine was badly scored from where the old fork had failed and this would have quickly chewed up a soft bushing.

I guess anything will wear out eventually, I'm gonna try the nylon bush and see. It baffles me that I can buy a short pivot but not the long but have to buy the complete release guide (FTC5218)!?

what engine and box

tottot · Oct 17, 2018

We still need to know what engine box you have?
I have had my 90 twenty five years now, I had the clutch fork go through many years ago[ late 90's] and found that the original pivot post had worn to a point! And there was no sign it ever had any lubrication from new. A new standard fork and new post went back in with a good dollop of grease at the pivot point.
Last August I felt the clutch getting a bit heavy so given the milage I decided to have a look. Took the motor out [ best way for me as I have a tractor loader ] and wanted to do engine seals as well.
Found the fault was a broken pin and missing paddle on one of the fork arms, however the fork and pivot point were fine even after many years use.
All new clutch parts went back in, this time with a fork as in James's post. Plus a dollop of grease.
