I'm rebuilding a BW 1356 transfer case for Project Brutus; figured I'd post pics and details here in case anyone was interested.
I picked up the TC several months ago from a guy in PA who parts out a lot of trucks. He had no idea on the internal condition. Anyway, now that the 7.3 IDI and ZF-5 are rebuilt and installed in Brutus, I need the TC done so I can finish the drivetrain and figure out what I need for a rear driveshaft.
As far as history, the 1356 seems to have been installed in Ford Broncos and trucks from 1987-1997 in both manual and electric shift versions. The F350 versions (and also some F250's, I think) can run a PTO. The one that I have has PTO capability as well as the speedo gear setup, which will work for my 1987 F350. Later versions of the 1356 weren't set up for a speedo gear.
Disassembly was quite simple; took me maybe 1.5 hours, and that's only because this is the first one that I've disassembled. Next one should be apart in an hour or less. Only specialty tools needed was a torx bit (T50), snap ring pliers, and a seal remover to pry the old seals out.
When I got it cracked open, I was quite pleased to see that it was very clean inside. The case halves are in good shape, there's no appreciable wear on the main shaft, there's very little evidence of pump rub on the case, and the pump looks like it's new or close to it. Chain looks nice, too. I'm going to get everything cleaned up, but I think it's going to go back together with only new seals and bearings.
