My 93 4.0 chimp suffered clutch fork failure on the way to chatsworth and a friendly garage in grimsby replaced the clutch/fork and bearing using standard parts for a modest fee and all was well - until yesterday when the pedal when straight to the floor and then jammed solid half way down, exactly the same symptoms as before.I am reluctant to have the fork replaced again if there is some underlying cause that will make it happen again - anyone had similar a experience? or got any helpful thoughts?

Have you got a tired (heavy) clutch thats causing the clutch fork to fail?

This post may help,

but you could have a problem with your clutch, is it standard ?
it may be sticking on the shaft and requiring more force than the fork can take to release it.

Cheap pattern arm/defective maybe?

Was the clutch any heavier after the job was done the first time, any odd noises?

I think it is very unlikley you would have had a "faulty" fork. Maybe they used the wrong bearing with too much throw on it?

If anything the new clutch had a much lighter feel to it, it bit smoothly with no judder and got me off the line at Curborough sprint with out any dramas at all and just failed during a low speed gear change in a 30 limit. I guess I will just have to throw myself and wallet at the nearest dealer.

Perhaps weld some reinforcement in to the next one?

Your're not the first this has happened to

No harm in making it stronger, but if this new(?) fork has only lasted 6 weeks there must be more to this than just the fork being weak.
Especially since the OP said if anything the clutch was even lighter than before the repair.

Strangley enough - just finished reinforcing my lever arm this evening - it looks like the one below .. but I've just added a bit of paint ..

Reinforcement in 3mm mild steel


I think you have a good point about the cause - the only culprit possible is the diaphram on the clutch .. they have been known to seize / get much stiffer.
