Help Identifying a Spicer 4x4?

[chevylookin]

Hello forum. I got this odd looking Spicer gear box from a friend who says another friend and his dad took it off an old Chevy truck long ago. The only identifying marks are the serial tag which reads: XC714 and then molded on the case which reads: CPI36-I or CP136-1. I have done a huge web search to find out what this is and how old it is and have returned nothing. Maybe farm equipment? The unit weigh about 50-60 lbs but its not that big and the driveshaft is rather long for a truck and is about an inch thick. I does look like it would attach to the old SM420 to the PTO cover. Is this an aftermarket old school 4 wheel drive for Jeeps and Chevy trucks?

it is a pto. if you can trace those nbrs back, you can find the application; for which trans that it fits. they all pretty well have the same mounting. it is the gearing which has to match up with whatever application and that is what the nbrs reference. they were used in trucks for things like winches, snow plows or hydraulic lifts and dump boes or beds

Thanks Ron, so its def. not for a 4 wheel drive then...

not essential in the operation of a 4 x 4 unless used to power a pto driven winch or blade.
