A 904 Rebuild Project I took on.
This shaft has to be removed to get the governor off.
Pump finally separated from the case.
Removing the band so I can pull the rest of the guts out.
One way clutch rollers and springs.
I used a big C clamp to slightly compress the servo so I could take the snap ring out.
The rear clutch pask inside of here was welded solid!!!! It was a task to get these separated. I ended up clamping the smooth part of the input shaft in a vice and using a big punch and hammer to tap it, rotating after every tap intil it started sliding out. All of the friction clutches were worn completely out. The steel clutches, and both pressure plates had too much heat damage to re-use. I was able to get two new pressure plates from a local transmission shop.
After separation!!
Valve body. Cleaning all of these parts up really good and getting them back together took the longest out of the rebuild. I completely put the valve body and transmission back together. After that, I then followed the instructions that came with the shift kit to install it.
