David,
I'm sure it's me that's being imprecise and throwing around the wrong term.
I was referring to the bearing that TRF refers to as "press-fit needle
bearings", or that I've usually called "closed-cage" bearings. To be specific,
Roadster Factory part#126862 is a bearing that runs on its own bearing surface,
whereas #150339 is what I would call "open-cage", which run on the layshaft. I
thought one was early type and one late-TR6, but I guess I'm not so sure.
I'm not familiar with the needle type in TR's, is this a TR4 or earlier
application?
Cheers, Tom

Subject: Re: [6pack] [TR] TR6 counter shaft
Hmmm, maybe I am wrong here. In the history of the TR tranny three types of
countershaft bearings were used. Needle, Shell, and Caged. I believe that the
needle is the earliest and that is the loose bearing that needs to be held in
place with grease while the tranny is assembled. Next is shell bearings in
which the bearing rides on the shaft and the outer surface of the bearing is
completely enclosed. The later is caged bearings which, look like a cage, in
which the bearing in exposed in the inner and outer surface. The names are
very descriptive.
I am under the impression that all ride directly on the countershaft. My
experience has been with early trannys; therefore needle and shell but am
familiar with caged bearings.
If this is wrong help me out here.
Thanks
