I have started taking apart the TR4 tranny that the PO purchased because it is syncromesh and I have the overdrive for it.
I was doing just fine until I came to the center mainshaft bearing. Part # 58391 StanPart Book page 27 item L3. I am following the dis-assembly steps in Nelson Riedel's article. He shows a tool that he made up to do the job. I was wondering if anyone out there has done this and how did you get that bearing out.
As I see it there are several ways to do it.
1. Might be able to use a split bearing puller
2. Could use a big hammer and bang the shaft in(really don't like that one)
3. Use a jig of the type he made and push the shaft through the bearing until it gets to a smaller diameter on the shaft.

#3 has the most appeal to me because you are using slowly applied force and not flaying away with a 3 lb sledge.

So what ideas are out there? Better yet does anyone have a jig I might borrow or buy?

Thanks, Tinkerman
 
I removed the outer keeper ring, then used the hammer technique with a piece of aluminum between the shaft and hammer head to drive the bearing and shaft out of the box, then I cut off the bearing. So place the case on the floor, whack away.

Oh, if you carefully cut off the inner race, it comes in handy to set gaps and select the proper thickness of the shims etc.
 
Stick with the manual, and just drift it out. I've just used a piece of hickory for years. It is a bit easier if you can clamp the bell housing down to the workbench (carefully) and better still if you have someone help by gently pulling straight back on the shaft, while your tapping from the front. They usually don't require much persuasion.

PS. Forgot to add, if you're changing out that same rear bearing, I think it would be worth to take it to a shop and have it pressed off. You can safely put a new one on with a suitably sized piece of cast iron pipe, just large enough to slip over the shaft but only contacts the inner race. Just tap the bearing on with the other end against a wood block.
