dirtymac Posted July 1 Share Posted July 1 I don't know if you have a divorced or married transfer case. With unit cases there's a 'collar' that bolts to the 4x4 transmission and another flange at the other end that bolts to the input of the transfer case. I got side tracked on the additional pictures but I'll get them soon enough :) In the mean time, would you happen to know if the Borg-Warner 1345 and the NP208 would use the same rear transmission support bushings?

I honestly don't know Will. I don't see any documentation in the Transfer case section but it may be in the chassis section. At the very least you have the BW service manual and some pretty nice exploded illustrations. Link to comment Share on other sites More sharing options...
Gary Lewis Posted July 1 Share Posted July 1 I honestly don't know Will. I don't see any documentation in the Transfer case section but it may be in the chassis section. At the very least you have the BW service manual and some pretty nice exploded illustrations. I think they are supposed to be in Documentation/Suspension & Steering/Crossmembers. But I remember looking recently and finding that the mounts, 6E039, aren't shown. And I remember posting that all 4x4 transmissions took the same upper and lower, but I can't find that right now. I'm installing spark plugs, but when I get done I can see if I can find it if y'all haven't. Link to comment Share on other sites More sharing options...

I found an illustration of the rear transmission mounts but it was in the manual transmission section. I think I posted that image already. The info doesn't state which transmissions it is for. This has been one of the more difficult things to figure out so far :) Link to comment Share on other sites More sharing options...

This has been one of the more difficult things to figure out so far :) I think it is fair to say that all 4wd Bullnose trucks used the same upper and lower "insulators", aka "bushings". (I realize that these are all E1's and the 1980 trucks had to have had E0 insulators, but apparently they were replaced by the E1's show to fit the 1980 trucks.) So, in order for people to search and find this post, all Bullnose 4wd trucks take E1TZ 6E039-A upper insulators, bushing, or mounts, and E1TZ 6E039-B lowers. Now I need to put this on the webpage...

Ok, I'm confused. Someone help me understand how these two illustrations fit with the above info. How can all 4wd vehicles use the same upper and lower insulators and yet 1985/86 4wd vehicles use the 2nd one - and I know that's the one Big Blue has.

Those two options are very different from each other. Link to comment Share on other sites More sharing options...

My '87 doesn't even have the bottom bracket (for a skid plate, I assume) Link to comment Share on other sites More sharing options...
dirtymac Posted July 4 Share Posted July 4 There's a sleeve with a flange on each end. It's plenty strong enough to support the transmission from the output flange at the driveshaft. I finally got some pictures. I found more holes in the floorboard than we were aware of. On a brighter side, I think I found the bushings for sale. I'll post that info higher up the thread. The first two are just the basic setup under the truck and the skid plate below the transfer case and transmission junction. In the first image, you can see how the two bushings don't look aligned vertically. These are close-up images of the bracket and the bushings. The first one is from the transfer case side of the junction. Someone has put grease in the space where the upper bushings go. The upper bushings are basically gone. There are some pieces still sandwiched in there but they're no longer a solid piece. One lower bushing is intact but they other is splitting apart. Both spin freely. Oh, and the part numbers on one of the lower don't exactly match up with what the book says or at least I don't think they do. I may clean it more later to see if I can read more of the number. The rest of these are pictures of the junction. So is this considered a divorced transfer case? I think the answer is no but I have no idea.

I was over at BroncoGraveYard looking at brake lines and some how ran across a set of "Transmission/Transfer Case Mounts, Round Mounts 80-86". They looked pretty similar to the pictures I've seen of the parts I think we need. The dimensions listed sound like they would work. Their description mentions the 4WD vehicles but they only have the part listed for the NP208 transfer case. I emailed them to find out what they might know. Turns out, they said these should fit any of the 4WD models so I ordered a set. If they work out, I'll post more info and suggest they list them with the other transfer cases. https://shop.broncograveyard.com/Transmission_Transfer-Case-Mounts-Round-Mounts-80-86/productinfo/31606B/ Link to comment Share on other sites More sharing options...
