    BW 1339 rebuild

    im rebuilding my transfer case and i want to replace my bearings... especially my output shaft bearing, its shot... doesnt move freely at all, but i cant find an exact replacement anywhere locally... can i replace with a bearing that isnt shielded? will it affect anything if i do this?

      Be careful of Chinese reproductions. Been a while since I bought one and pretty sure you can find a match at NAPA. When you say shielded... You mean the "cap" on the bearing casing so you can't see the ball bearings? It does help debris from getting inside but don't think it is a requirement to have it. I am open to other opinions.

        I did a quick search on Rockauto.com and found a National bearing part number 206S for the front output shaft bearing and a 306 for the rear. A little over 20 bucks plus shipping. Tonight when I get home I will grab some of my extra ones and take them to Napa to try and get a replacement number. I agree with Flint, stay away from any Chinese replacements. Should be able to find a US made one... I will reply tomorrow when I have the bearings.

          I got home this evening and pulled out some spare bearings I have. It looks like Rockauto has the correct bearings. The stock bearings are made by Federal with a front part number of 1(or I)206FC and a rear part number of 1(orI)306. Measurements provided by Rockauto are correct too. Hope this helps.

            well i found a bearing at advance it's a national 206 which is what came out of my rear output for some reason? but the bearing from advance isnt shielded like the old one, wasnt sure what impact that may have if any?

              bearings

              try king bearing or a bearing house , they should be able to match it up, search bearing locally in yellow pages , these places provide good value for seals as well

                  You are assuming that a case that is 25 yo or more has never been repaired and that the PO put the right one?

                      Help with QuadraTrac full rebuild

                      Sorry for resurrecting such an old thread yet,

                      Ok im the middle of a full rebuild. Everything is done from cones, chain, needle bearings, washers, ect everything yet output shaft bearings.
                      Ok so here is one that has me really stumped.
                      Local bearing supply actually had the books for the QuadraTrac output shaft bearings, they listed them as Timken 6206-Z.
                      Saw on another forum the Timken 6206-Z were the right ones. Pulled the original Federals out.
                      Well tried to put them in couple days ago and they don't fit!
                      The outer diameter is to small, they are 2.44 od, and the original Federals outs are 2.49! What the heck is going on here! It's out by 50 thou? And I have a spare donar case that's 5 years older and the Federals in it are 2.49 as well.
                      The bearing supply place is trying to find a 2.49.
                      Anyone have any input?
