It should not be bent like that. You need a new fork.

This explains your problems. Hard to know how you bent it.

OK, so I guess, as I didn't place the fork correctly at first (out of the throw out bearing clutch slot), the two arms of the fork just took the form of my gearbox case as I was trying to adjust the clutch cable i was pulling it many time where it shouldn't be : on the gearbox case wall.

easy fix anyway (once the transmission is out). Put a small amount of moly grease (Redline CV 2 is good) on the fork tips / bearing groove as well.

Thanks for all the tips. Let's see the result in 2 days the time to receive the new part.

I am experiencing a similar problem. Did replacing the fork fix your problem?

Hi Bill,

The bent fork had to be replaced.

Basically the fork was not "engeaged" into the diaphragm slot. Therefore when you pushed the clutch pedal, it would bend the fork.

I used an endoscope to check with a new clutch if it was engaged or not. Placed it on the bell housing hole.

Old bent fork would'nt fit anymore.

With endoscope, you can make sure that the fork fits the slot as the picture below. The first time you do it, you shouldn't have "the feel for it". I'm sure if I would do it a second time now, I could do it without the endoscope



Hope that helps solve your problem.

Hi Nicolas, Thanks for your response. I ordered an endoscope from Amazon. Waiting for it's arrival. I want to see what's happening with the TO bearing/fork before I drop the engine/trans. When I mated the engine/trans I watched carefully to ensure that the top arm of the fork slid into the slot atop the TO bearing. However I could not see what was happening at the bottom. Definitely something is not quite right.

Tolerances are quite thin.
I had to play with the clutch cable arm (to rotate the fork), while pushing the engine in, while watching what's happening inside through the endoscope.
Once everything lines up, that's good to go.
Not that straight forward.

@theiceman > the picture you see above was taken with the endoscope from amazon. But it shows the top part of the fork. If the fork is bent, I would say, it could'nt slide into the slot at all in any cases,

yeah i see that and i agree, if your fork is straight and you can see the top, bottom is fine.
