DIY Transmission Re-Build Tips
I'm currently starting to assembly my evo 8 5 speed trans, is there any tips or tricks to pull the races back out of the cases? Mine is a slight press fit so it obviously doesn't come right out. Any kind of homemade tools anybody made to pull the races out? I'm assuming it would have a 90 degree bend and fit in the two little slots to wedge it out. Any tips or tricks to get the races out?
They are not pressed in except the bell-housing diff one, did you read the rebuild manual?, they use a special tool MD999566 to get them out but they are still just slide in. But its just a claw tool. you can make one on a bench grinder and then attach it to your slide hammer.
The mainshaft bell housing side is usually the hardest one to pop out. If you get them stuck, just tap them back down again until they are even and pry them out one side at a time or if your hands are small you can probably pry both sides at the same time but you'll probably cut your hands on the sharp casing edges. Also I'm assuming you've probably created some burr's on the casing, so you will have to knock the cup in and then de-burr the mushroomed edge so the next time the cup won't get stuck on it.
Take a small propane torch and heat the edges if needed but I've opened 6 transmission and only needed heat for the diff bell housing side because that is a press in.
By the way the one upgrade I didn't read is to change the tcase bolts from 8mm to 10mm.

Are the Outer Races that sit In the Transmission Housing suppose to Spin Freely?? My thought is that the Races are suppose to sit firmly in place while the Input/Output Shaft Bearings spin on on the Races themselves. Upon disassembling the tranny, the races spun freely with the turn of my fingers.
