Your transmission, is overfilled. There are no seals, in then
Crosley/B-W T-92 transmission. There is a plug, on the side of the
case, the gear oil needs to be NO higher than the bottom of that
As far as oil, if you can find a lube, without sulfur in it
(possibly the 600 oil), it would be better, as sulfur deteriorates
brass/bronze and the transmission has brass/bronze bushings in it.
I PERSONALLY don't recommend using straight STP in it. The viscosity
is WAY too high, using up precious horsepower, of which the Crosley
is NOT, over-endowed with.
As a lot of folks on her know, I've rebuild a LOT of Crosley
transmissions, just take it for what it's worth.

I recently took the top of (1948) transmission that has sat
idle for 50 years. Goal was to drain fliuds, clean and inspect
and put back together. The good news was the gear oil was still
intact, and all the internal gears look great! I dumped old
oil, and cleaned thoroughly with break cleaner to remove any
particulates and dirt. The top and bottom seem to have little
wear and all teeth are there and in serviceable shape.
I put top back on with new gasket, and refilled with 85W140
gear oil... Now, while sitting on cement floor, I have fresh
gear oil weeping out both the front and rear spindles.
It didn't leak like this beforehand.
What did I miss? A seal? Is it just a bit overfilled?
If there isn't a seal of some type, doesn't gear oil always
leak out even if the level drops below the shaft height?
And a separate question: On the top, there is a 1/4 hole where
I can look in and see the top "fork slider" shafts. Should this
be capped in some way?
Thanks fellas... New to all this.
