transmission rebuild question

[bmp]

Well I started my transmission rebuild today.  I have 2 questions?

1.  How do you get out the old output shaft bushing?

2.  (I got my bearing kit from roadless gear) the factory original large bearing that is on the input shaft is a closed bearing and the one that came from roadless is open, is that right?

I had mine rebuilt by a mechanic.    I didnt replace the bushing.     Have a look at it and see if there is little tiny spark welds.   The guy told me he sees that a lot and its a sign of a bad ground wire.   The shaft and bushing are arcing.


My front bearing in the kit was open.   The stock was sealed.

I use a shop press and a big socket. Be sure to use red loctite on the outside of the new bushing, and make sure the oil holes line up.

The OEM bearing should have been open.

My replacement bearing doesn't look like the one on top in this pic

ok  I have gotten to the main shaft and know I can't figure the best way to remove the last bearing?  In this picture you can see what I'm talking about.  It looks to be a sleeve in front of the bearing and I can't get it to move.  I think that it has 2 little balls under it.

yeah that is a great writeup and I have printed it out and been following it, but they kinda glaze over the details of pulling that part of the shaft.

Workin on it.

That is a roller bearing journal. Just put your bearing puller behind the ball bearing in front of it and it will come off as the ball bearing comes off. Ya,  there are two balls in there to keep it from rotating. Shouls be a ble to move it with a brass drift to get the ball out with a magnet.
You will need to reuse the original ball bearing snap rings IIRC. If there is a snapring on the rear countershaft bearing be sure and remove it. Original bearing doesn't  even have a groove.

I think the "sealed" bearings are probably better quality. keeps lube in and particles out, but the kits have unsealed bearings.

To change the extension housing bushing, I heated the bearing area on a camp stove and drove the bushing out with a socket and suitable pipe. Did the same to install the new one after it spent some time in the freezer. Very easy. Mark the oil hole line up with a marker.

Well guys thanks for all your help!!!!!  I have gotten all the bearing changed and now on to replacing the bushing..

Again thanks for the help guys..... I got it all together this afternoon.  Just to update what I did.  I hate it when folks have questions and they never come back with what they did to fix it. 

The key to getting that journel off is getting the little balls out first.  You can't pull the bearing and the journel off at the same time because the ball stops the bearing.  So I got the journel and the washer behind it with the puller jaws, Enough so that I could get the little ball out.  Then I pressed the hole thing off.

Next the bushing..... I couldn't get a socket to press it out, so I took a screwdriver and split it into.  I pressed the new bushing in with a socket.

Bumping this up, how'd your rebuild turn out?

I'm thinking about doing this myself. I have enough skill and support people here to do it.. still a little nervous.

the rebuild went real well.  I prolly spent as much time taking it out and putting it back as I did rebuilding it.  I found one of the bearings was making a thumping sound when I turned the tranny by my hand.  So that made me fell better, Knowing that I was actually fixing the problem that I was having.  I had to take the tcase and exhaust off to get the tranny out.

This link is good for helping   with pics

If you have a bearing press and a good bearing puller you will be fine,  I had to borrow a real long bearing puller to get off one bearing.

Also the factory service manual is good    but i used the izook info more

Yeah, we have a press and I assume there's a bearing puller around here between all the guys that work here. (We rebuild turbos)
