Fabco TC-140 transfer case parts
The TC-140 was built in three styles. The parts that differ are in the lower shaft.
The Fabco TC-140 or TC140 is a two-speed transfer case, and its manual covers three styles: a declutch case, a case with a 26/74 differential and a case with a 50/50 differential. The differential cases also carry a lockout. Knowing the style is the first question we ask, because the lower shaft, the bearing kit and the seal kit all change with it.
The book also covers a PTO or a direct pump drive, the lubrication plumbing and a page of overhaul kits, including a pinion kit and the differential case set for the 50/50 case.
