TR4/4A TR4A Clutch Release bearing

[karls59tr]

What is the best way to remove the bearing from it's sleeve? Do I need a press to install the new bearing on the sleeve? also I have new release bearing that's been on the shelf for years and the grease is hard. What's the best way to get the old grease out and should I use " wheel" bearing grease when I repack it? :confuse

TRF makes a tool to press it back in place, it rotates the bearing while pressing it, which may be better than just pressing it in.

I would soak the bearing in kerosene to loosen the old grease, and to a final flush with brake cleaner.

Wheel bearing grease is what I would use.

I wouldn't try to regrease the TOB; the original grease was a special formula that turns freely but resists throwing out. Unlike the TR2-4, the 4A-6 clutch has the TOB turn all the time, under the very light force supplied by the spring inside the slave cylinder. If the bearing (or grease) is too stiff, then the bearing rubs against the clutch fingers and tears them up. In some cases, it shows up as a hideous squealing noise.

This photo, from the Buckeye Triumphs excellent tech article on the subject, shows what can happen if the bearing is too stiff (which it seems many of the "heavy duty" bearings are)

I made a tool at home to install the bearing, pretty easy, a bolt, a nut, and some big washers, I don't have a pic handy, but shouldn't take too much imagination to figure it out, you need big washers to fit over both sides of the bearing and sleave, which may merit a trip to the hardware store if you don't have such lying about. You can even rotate it as you press it on with this method if it makes you feel better about the process.

the Buckeye's Article has a good picture of such a tool:

That's it!, I didn't get fancy and weld the nut on, but that would ensure that you turned the bearing as you tightened it down.

I'm with Randall, if the grease is old, don't use. Too much work to have to pull the trans again. I've always used a vise to install the bearing on the housing. Haven't ever had a problem.
