Chicago Aux. Trans.

[Craig Leach]

Hi Guys,
A freind just picked up a Chicago Aux. trans is the pocket (center of main shaft beraing ) like a Warford made out of unobtainium or is it a standard type bearing that is available? Thanks.

Craig, I was up to my elbows in them a couple years ago here. ( thanks mike !). There are at least two different types, one appears to be pretty common bearings and the other was a real wild style, something prehistoric looking. They WERE NOT interchangeable, and I had enough of the good modern looking ones to complete my mission. I forget now if the cases were interchangeable. Hope this helps a little.

Tim,
The way my luck goes this will be a jarasic park one. I forgot to ask what the length is on them are they the same as a warford? This may turn out to be one of those I should have said gee I cant even spell model T things.

I have 2 Chicago transmissions and the cases are different. The input shaft bearing bore is larger on one. Both use the same bearing in the center. Bearings were still available last fall, and I think that bearing is the same as the cluster gear bearings. Dan

If I remember right the case's with patent pending on them had the oddball bearings.

Side request - does anyone happen to have a spare input shaft for a Chicago? I really like the transmission but the square part of the shaft the goes into the 4th main is beat up giving excess lash in the driveline.

Thanks Guys,
Looks like it will be on the bench soon.
