Need help in identifying this Chevy manual transmission.

Recommended Posts

It's not an antique car but the tranny is a Chevy manual and I am not having any luck in the identification. I was hoping this may be a good site to help me. It is currently installed in a 1950 mini crawler. The crawler came with a Crosley manual and at some point this has been switched out for this Chevy. Any help is appreciated.

Stamped numbers are:

3 speed, should have mentioned that.

This would be a 1928 3 speed unit. It should have a casting date on it in the form of F 13 28, which would be 13th of the 6th month (A=Jan, B=Feb) 1928.

A 1928 huh? Interesting. I haven't found any other numbers stamped on it but there are a couple spots still with some grease and dirt. So the numbers I did identify don't mean anything?

Any idea how durable they are, it's in a dozer so needs to be sturdy.

Are parts available?

May I ask how you knew it was a '28? Is there an ID source available?

Are there other years that can be used as a replacement?

Sorry for all of the questions. It must be similar to the original Crosley I am guessing.

Just under the casting number in the first picture is the date C 30 8. The gearbox was cast on the 30th March 1928.

The engine produced about 35 HP so the gearbox is designed for that. Spares are available.

Casting numbers for early Chevy's are:

I heard the Crosley trans were originally made for lathes or some other equipment so the Chevy trans should be much tougher.
