Two Speed Transfer Box

[Phil Waterman]

Hi Ken

First step is to really identify which transfer case and which PTO. Depending on how many rebuilds, repairs, different mechanics who have worked on them CMPs that I have seen can end up being a real mix and match as to what parts it started life with and what may have now 70 years later. Chevy trucks with Ford Engine Transmissions groups were supposedly common in North African rebuilds.

If I remember the service bulletins correctly Chevy used at least 7 different two speed transfer cases. There is also a note in the Chevy service bulletins that I read as saying not all two-speed transfer cases even have the parts internally to accept a PTO. Simple logic why do machining on a transfer case that may never be needed.

Looking at the Ford parts books I have I don't see any mention of interchange with Chevy.

For our Ford guys what are the indication that it is a Ford Transfer Case?

Cheers Phil
