[Fot] TR6 transmission rebuild - counter shaft gears

[van.mulders.marcel at telenet.be]

These shell needle bearings are easily damaged : when the shell is warped a bit, it will fail. When the bearing is in place, one should check if the needles can be spinned freely. 
A nylaton bush of the TR4a -TR6 inner wishbone bearing is great for pushing these shell bearings in place. These bearings are not secured by a circlip, contrary to the open cage needle bearings. 
But the needles of the open cage bearings are running directly against the ev. worn or damaged inner surface of the laygear.

It probably has the later type shell bearings and 1 or both have worked loose in the laygear housing bore and "milled" into the thrust washer (s).

Subject: [Fot] TR6 transmission rebuild - counter shaft gears 

I am rebuilding a TR6 transmission and ran into a strange snag. When I removed the countershaft the counter shaft gears did not drop to the bottom of the case. I had to tap on the counter shaft gear set with a brass punch to get them to move far enough to allow the input shaft and gear to be removed. Now that I have the main shaft out of the case, I can't get the counter shaft gears out of the case. I've been able to move them a little bit by tapping on the gears with a brass punch through the drain hole but I can't get them out. Has anyone run into this before? Any ideas to get them out? 

Thanks.
