Transmission Rear Housing

Post by DogRocker »

Any tips on getting the Rear Housing cover off? Mine seems to be stuck. I've tried rigging a puller. Sliding various objects between the Main case and Rear Housing. Pried, pulled, and will only move about 1/8". I removed two bolts and four nuts. I also removed the Shift Engaging Lever Assy. It feels like something is still attached, but it's not obvious to me what.

After a 3+ hour fight, I finally got it off. The Countershaft Bearing was glued to the Housing Cover with what looks like Locktite. Also, looks like some water might have gotten into the rear section.

That may have been put in to resolve a spun bearing egging out the housing. When bearings fit loose an anaerobic bearing compound may be used to save the cost of having the case welded so it can be re-bored or machined to take a sleeve.

After reading around the internet I'm starting to think it's an anaerobic gel. I think you're right about it being used to cure a housing issue, because I noticed some scoring within the "cup" on the housing where that bearing was seated. Apparently, anaerobic gel dries hard in the absence of air. As a result, it made that housing nearly impossible to remove. (I had to used a puller attached to the output shaft until I heard a "snap" where the glue finally broke off the bearing.)

So, I'm thinking I'll need to buy a new bearing and see how it fits. If it's not tight...take it to a machine shop or weld shop? RTV?
