Its an easy trans to rebuild. You have to be careful of not getting the needle bearings in place during assembly. The only special tool is a puller for the rear bearing. It pulls the bearing and speedo gear off. Should take about 4 hrs if you don't need parts.

Will a regular gear puller work?

Re: 3-speed rr

Step one is to get your hands on a factory service manual that shows diagrams and photos and gives detailed step by step instructions on how to rebuild one. The aftermarket books assume too much or don't cover it.

It's usually easiest and less messy to drain the gear oil out of the trans before you pull it.

Then I would suggest cleaning up the outside of the case and getting all the grease and dirt off it before opening it up. But that goes on any part you work on.

I haven't hunted for parts for one for years so I am at a loss on finding trans parts and gaskets out side of looking first at the regular vendors for truck parts and checking Napa and other local sources.
Nothing on Napa online but you might check with the store you go to.

There are some on ebay. search muncie 318 bearing kit . they cost about $90. You should be able to get a shop manual there as well.
