Unidentified ball bearing

azopelnut · 07-02-2007

This past Sunday I was removing the engine on my 73 Ascona and thought it would be easier if I removed the 4 speed tranny first. To avoid a big mess I decided to drop the tranny pan to dump all the fluid. When I did a ball bearing a bit smaller than an average pea dropped out with the tranny oil....
WHAT IS THAT???
ANY IDEAS??

There should be a spring and a ball bearing. The ball bearing goes first, followed by the spring, then the pan holds it in position. It is a selector shaft 'detent'. Gotta have it!

The spring is .297" OD (about 7.5 mm), and roughly 1.4" free-length. I don't have the ball bearing diameter offhand.

The ball bearing is 5/16" (.3125")

And there ought to be a little round shoe that fits under the spring as well, the last bit to go in, but I don't know if you can't get along without it. The bearing, spring and shoe all fit in that order into the hole on the passenger side of the casting, not the selector release side. If you try to install it there, the bearing should roll out the top as it did for me once but you don't want to lose it in the box.

I like the nifty magnet in the base to catch shavings, but I'd just as soon they put a drain plug in the thing.

If you don't put it back in then you wind up having to hold it in gear and it's hard on the synchros.

5/16" = .3125 = 7,9375 = 7,94 mm
8 mm = .3149
diff = .0024 = 0.06096 = 0,06 mm
