Gary Lewis Posted July 27, 2023 Share Posted July 27, 2023 Well, well, well… I just picked up the replacement TC (BW 13-45) rear shaft seal at the nearest NAPA. Really not sure they sold me the good part. This is the new I got: And here are some pictures grabbed on : They are absolutely not looking the same. Can someone tell me if I have the correct replacement part on hand? That's not the right one. Your screenshots from Youtube are correct. I'm not saying the one you have won't work, but it is the wrong one. I may have the part number in Big Blue's Transformation thread since I had to replace the first one because I didn't get the nut tight enough.

Not a lot popping on the web, maybe my search criteria aren’t correct… Found one seal looking right, 27$: But Bronco Graveyard sells a kit that seems to contain the right seal, for 18$. I suppose the rear shaft seal is included, but not 100% sure: Link to comment Share on other sites More sharing options...

That's where I got my parts. Link to comment Share on other sites More sharing options...

That's where I got my parts. Could this possibly be the difference between a slip yoke and a fixed yoke output? I know my slip yoke 1356 has the conical type seal.

Yes, that’s exactly what the difference is. You have a slip yoke and we have fixed yokes. Link to comment Share on other sites More sharing options...

BigBrother-84 Posted August 11, 2023 Author Share Posted August 11, 2023 As for the t-case, it looks like Big Blue's twin so you have a BW1345. Look closely in the wedge-shaped recess next to the rear output opening and you'll find it says Borg Warner 13-45. If the green arrow points to the fill plug and the red one to the drain plug, seems that there’s not a lot of oil in a BW-1345 TC. I’m a bit surprised. Any advice about the oil type and/or quality?

No, it doesn't take a lot. There's an oil pump that moves the lube around. I'm running Amsoil Multi-Vehicle Synthetic ATF in mine. Link to comment Share on other sites More sharing options...

Wanna know what happened to Big Brother’s Speedo Drive Gear? The plastic gear sled on the steel shaft… Ever seen something like this? Link to comment Share on other sites More sharing options...
