Inspection of a 904 torqueflite

I was able to get the sun gear bushings in no problem this time. They rotate smoothly. The sun gear seems like it’s rotating funny.

When I pressed the bushing in. I did see it flex a little. I didn’t have anything supporting the gear on the bottom side. Next time I will or I will remove the sun gear and press the bushings in. I’m hoping I didn’t warp it. I don’t think so. I can check run out.

On the other end.
I have pressed in 3 reaction shaft bushings into that housing. All went in smoothly. All 3 of them for the 999 compressed and put a high spot in the middle. The 904 didn’t do that and went in fine.

When I pressed the reaction shaft bushing out. I tried to put it on the race by itself. Even by itself it wouldn’t go on. It hit that ring and stopped.

I checked it before pressing it. It was loose and fine. What’s with this. Third one and the just get high spots in the middle.

This time even. It compressed so much it didn’t even want to clear the input shaft splines. I used the splines teeth to cut the bushing down until it at least cleared the splines.

Then I used them some more to see if I could at least cut that high spot. It never would cut it to the point it went in.

So I thought I’d try something. Pressing the bushing in further.
What it did. It made the high spot larger and compressed it even more.

It never bottomed out. It never had a huge amount of resistance going in.

These things are getting expensive because the shipping is like $7 for every purchase.

I even cut the driver down to make sure it went in smooth and cleared the housing.

I did put them in dry. But I put them all in dry. Lubing the outside of a bushing asking for it to spin the bushing.

I’m pretty stuck on this. I can go ahead and get ten more and keep trying. But I’m not really sure what’s up.
