D20 Rear Output bearings

[Rocko1012]

Need help on putting roller bearings back in output shaft. How far do they go in. do they ride on first part of shaft or second. See pictures.
Advice needed. should i have install adapter to transfer before installing to transmission?

This picture is a little blurry but you can still see the shinier section where they were riding so I'll say all the way in.

Bearings

That's a good picture of shaft. It has multiple ridges (lips)inside. I tried all the way in shaft installing all bearings, but the last one would not seat all the way in. I put bearings in freezer to shrink metal, and will try when garage warms up. Thursday? I know its not rocket science to get install. but its a pain in butt.

Thanks for your reply, Will let you know how it works out.

You just have to slide the last in from the end. It won't fit from the side.

The three holes in the back of the pocket for the 13 bearings are the oil supply holes for the rear output bearings. Use petroleum jelly to hold the 13 bearings in place. If you use high temp grease or wheel bearing grease it will take awhile for the rear output bearings to get a good supply of oil.

Looks like your shaft is a bit different than the one in my 72. The oil holes look to be larger and have a chamfer. I think someone had a better idea to get more oil to the output bearings.

That's out of my 74'. They may have done some better engineering.

Viperwolf has some good advice sticking it in from the end, they are that close in tolerance.

Transfer info

I finally got the bearing to drop in from top. As posted earlier. Question I put new shims on Idler shaft and cannot turn by hand. Is that normal or believe i have problem. Every thing shifts great. See pics of problem bearing. and complete assembly. Tough for one man.

Thanks for all the input and suggestions

If you can't turn it by hand it's too tight. I know some new thrust washers are made too thick. You might need to replace one with an old washer.

Mine is a 67 T-shirt Dana 20, yours looks like the J shift. Mine had no shims on the idler shaft and just had to thrust washers on one on each side of the case, but there were three washers one in between the roller bearings and one on either end. It is a good idea to check everything As you put it in to see if it rotates. So if one thing doesn’t spin you know it’s related to that last step you just performed. If I can do it you can do it.
