Bellcrank install and torque
« on: December 08, 2013, 06:25:30 PM »
I installed a bellcrank repair kit and am having a tough time getting the bellcrank back on my M38. The inner bearing sleeve hits a same diameter piece coming out of the bottom of the frame mount. When I fully install and torque the nut on the shaft the bellcrank binds and is impossible to move. If I were to drive the bellcrank inner bearing sleeve down it would no longer be flush at the bottom and cause a problem there too. I am cross-eyed from scouring the web for a detailed bell crank install procedure and exact fitment of components. Can someone point me in the right direction or tell what's wrong from the pics? The rubber dust cap has intentionally been left off here.

Hi Ryan,

My bell crank frame bracket does not have that flange hanging down.� Could it be the old� sleeve still stuck in there?

Unless there was a design change on the bell crank bracket for the M38???�

I could go disassemble mine real quick and take a couple photos.� Let me know.

Good question and I figured it was coming. I don't think that's an old sleeve. I drove the old one out of the bell crank and have it sitting here now. It's identical to the new one in the rebuild kit. It is nice to hear yours does not have that - something is amiss.

Ryan I agree...there is an extra part there..a bushing or a sleeve...and it's hanging down and binding...I too have been looking on the internet, but no luck so far...Can you look down from the top of the frame fixture, with a mirror, or maybe feel if there is a ridge in there?

Also, will the cinch bolt come out or is it stuck too? Maybe there is a sleeve that has moved....

There wasn't a big old flat washer or spacer there, was there?

Also, it seems to me that with the old pin out of the frame fixture, you could see into the gap ....of course with the engine and radiator in there it might be a problem....

If it is an extra sleeve the diameter is right because the bolt slide right through as it should. If I remove it I would be left with too wide of a hole in the mounting bracket. And I'm not sure it would come out anyways.

It's tough to see in this pic but the whole thing is slit from the top to roughly halfway down. This is presumably to it will flex when the pinch bolt is tightened. I can run a razor blade right down that slit from the outside.

That is odd...It seems to me that the pin has a groove in it to allow for the pinch bolt, but it does not look as though the pinch bolt would even touch the pin....

Did you measure the old pin and order based on that, or did you order an M-38 rebuild kit? Can you show a pic of the new and the old pins?

Now I see that the kit Walcks offers covers all the 2a-3a-m38  etc....

Weird....

OK...Now I'm going way out there...

Is it an M-38 frame?  Does it have a machine gun plate?

I reinstalled everything with the old bolt as it is slightly different from the new bolt. The bell crank no longer binds but it still seems weird that the bellcrank bearing sleeve mounts face-to-face with like "sleeve" hanging out of the frame mounted bracket.

It leaves quite a gap (more than before I took it all apart for the first time this morning) but the rubber dust cover thing that was there is about the same width as the gap. I have this posted on willysmjeeps with the hope that someone there will provide a pic of their M38 bracket.

I'm pretty certain the frame is M38. No machine gun plate on those, right?

I thought all the military frames had the plate...but I'm probably wrong, as I can't find a picture of one with the plate...

There is a poor picture here of a bellcrank, maybe there is a rubber spacer/seal in there..

Are the front frame horns boxed in? Of course i may be wrong there too....

Tim - you are too accommodating! So it looks like your bracket has a sleeve in it too. It's upside down from mine. Since it is flush with the bottom of the bracket does it stick out on top or is it flush there too?

Ryan,
Mine is flush at the top and flush on the bottom.

Randy - That pic of the M38 Bellcrank appears to have a spacer in it. I really need to find someone with an M38 for a close-up of that bracket. And yes, my frame horns are boxed it. Shock-mount studs are threaded, and battery tray is different and  clutch/brake shaft pivot mount is bolted to the frame

..and Tim, I almost feel guilty that even after your glorious "first piece" press conference, within a week you felt compelled to remove it to help me out ..... ;D ;D ;D

No worries, it is still easy to get to.  You may have to see an M38 frame, but I'm almost thinking you could flush that up and be in good shape...as long as you have enough thread on the shaft.
