Maybe it is a non issue if the clutch disc holds it in place during normal operation, but if it goes crooked it may not slide back to the retracted position again.

the springs should give it enough pressure to move back.

if not, you'll know!

Andy -

I bent the fork just like you said and it worked. I have plenty of throw now and I only had to use 3 washers under the pivot - plenty of thread left. The fork was a bitch to bend. I heated it up thoroughly with a Mapp torch and that made the work a little easier, but I still had to bash it with a brass hammer as hard as I could. That fork is one tough piece of metal!

How much did you have to bend it? Do you have a photo of the bent fork installed?

Well, I would have a picture, but someone STOLE my digital camera. (IMG:style_emoticons/default/headbang.gif)

I bent it about 1/2" towards the engine, measured at the tip of the cable end. It was totally by eye and thinking hmm this might work, maybe I should stop thrashing it now. (IMG:style_emoticons/default/biggrin.gif)

With the bend plus 3 washers under the pivot I had very close to the 20mm clearance from the fork to the transmission casing.

Andy - maybe. I dont want to break anything else just yet. Very paranoid these days.

Time to bump an old thread!

I am about ready to stick my rebuilt and regeared 901 onto the LT1. I have a Renegade adapter and a KEP flywheel, PP, clutch disk and release bearing.

My understanding is that bending the clutch fork or adding spacers on the pivot ball is required due to flywheel resurfacing. Well this flywheel is brand new, and I only have about 10mm of space instead of the required 20mm. It looks like I would need about 1/4" of spacers.. too much. So do I just bend the fork and git-r-done, or do I have the wrong release bearing? I measured the adapter thickness before I ordered all the other stuff from KEP, so it _should_ be right.

I am having a simular problem. My clutch is worn (flywheel too probably) and the fork starts its swing at about half the distance it coule go. It hits the tranny right at dis engagement. I think I may need a new flywheel as well as clutch and associated stuff. Is that what you are seeing? Is the fork not starting close to the engine? Is it starting about half way through its possible swing? Is so be sure to get it right before you drive. When it hits the tranny you will break the cable and / or the connection at the pedal. Crevix or priviot or some damn named thing. About 15 bucks total out the door from the bird (ask how I know) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) and about 2 hours to install. At least that is how long it will take you if you drop the new bushing into the tunnel like me...
Good luck. Let us know how it turns out. Mabey we both have the same to bearing and its the wrong one! I hoipe I hope I hope!!! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

I know that (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) will work but I also know that the factory was able to make it work without doing that. (god I hope) so there must be a way to do it Quote Right.

I actually have it worse, it's more like 2/3 towards the back of the opening. I need it to start out closer to the engine.. I'm pretty sure it wouldn't disengage at all the way it is now.

I'm having a similar "issue" as well...
Installed the tranny today on my new longblock/ with sachs clutch pack.
Only to find that when I move the clutch fork, the t/o bearing will not engage the clutch (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)
Guess I'll pull it back off, look to see how many shims are
installed, & use the torch if I have too. Thanx -
A couple picz -

The lever is completely free in it's travel & when I pull the lever to the rear, the t/o bearing does not travel enough to touch the clutch disk.

No - I didn't bolt it together. Just did a "test" fit.
After I posted I went back & attached 2 bolts.
I now have a 'lil contact with the pressure plate with the
fork when the fork is near full release travel.
----
This engine has a lightened flywheel. I just didn't
anticipate how much difference it made in relation to clutch
release travel (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)
The pivot has one (1) washer/shim. What's the "max" stack-up
of shims for the pivot??? It would seem that I need to add shims
to move the fork pivot point forward. Anybody ever have to clearance the tranny case to obtain more travel??? (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)
Thanks
