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
 
In the past, I've used the hammer approach, but always with a socket or piece of pipe over the end of the shaft to protect it and bear against a shoulder. I don't believe my relatively small hammer (~2 lb) is enough to injure the bearing, but I'm usually replacing it anyway. There isn't room inside the case to just drive the shaft forward, so I first drive the bearing back out of the case, then stick something between the bearing and case (used lathe bits last time, I think) and drive the shaft forward until the bearing is loose.

But here's an article showing how to use a bearing separator : Greasy Hands Gearbox disassembly

Thanks for the article link. I figured that I could use the split bearing seperator. The pictures make it all clear. I am going to replace the bearings, though I think I may take one to NAPA and see if they can match it up with one of their stock bearings. Moss is mighty proud of those rascals. I have a set of NOS syncro rings that I plan on using. Fortunatly all of the gears look to be in superb shape.
I really appreciate your consistant help to all of us on the Forum. If there is ever anything I might be able to ever do for you feel free to email me!

Regards, Tinkerman
