I just installed a new clutch linkage kit and I was wondering what the "safe" distance between the bellcrank and the frame should be? I currently have about 1/4" distance and I'm thinking if there is any movement the bellcrank may hit the frame. I bought the kit because the pivot bracket broke (after 20 years). I don't know what the clearance was before it broke. Also I adjusted the clutch to have about 1 1/2" play and the clutch now starts to engage after the pedal is at about the 1/2 way point, before it used to engage closer to the floor. Not sure what the correct point should be. Thanks

Is your bell crank touching the frame ..... If not you are good. A clutch that engages near the floor is a clutch linkage that needs to be adjusted. You want a clutch that fully disengages at the bottom without clutch plate drag and allows for complete clutch engagement at the top. All allowing for heat expansion when everything is hot.

Have you checked the condition of your engine and tranny mounts?
It should not be that close.
Can you post a picture?
This is pretty much what you want here.

Here is a picture. The Jeep is lifted and there is an extension for the pivot. I just don't seem to recall it being that close before I changed the parts. (I could be wrong). Thanks

The engine and trans mounts are ok.

Crank not touching frame, you can see the picture I previously posted. Clutch seems to be OK. It just may not have been adjusted properly before. You just don't seem to notice little details until things change.

A good gauge of a bad motor mount is when the clutch bellcrank is not perpendicular to the frame. This can put excessive load on the pivot point and break it. Other indicators would be the rear of the valve cover getting close to the firewall and the gear shifter getting close to hitting the shifter cover. With the bellcrank that close to the frame, I would suggest replacing them along with the tranny mount. Then at least you will have a history of replacement. Those poly mounts would be a good choice.

That bell-crank is WAY to close.
You can't leave a driveway without it hit'n the frame.
Please post pictures of the tranny mount.
How did you check the mounts out?
Also-how close is the bottom of the fan blade to the radiator(6 o'clock position) compared to the top(12 o'clock position? This can be an indicator of engine position/alignment issues.

Fanblade edge is 1 3/4" from radiator top and bottom.
Trans has poly mount in good condition.
Engine mounts look conventional. Tested with crowbar and seems tight.
I can try to shorten the extension for the pivot and reinstall. What should a safe distance from the frame be?

I would say at least 1 inch of clearence.
I have almost 2", with a 1" body lift and poly body bushings.
Were's all that oil coming from, in the pictures?
