Round #2

Now that the studs are removed (by whatever method you had available to you), it is time to salvage the front output shaft bearing from the housing.

Seal puller used on the front output shaft seal

Of course, Alan wanders over to the tool chest and comes out with a seal puller.  Now I new there was such a tool, but I had never seen one.  Today was my lucky day, as Alan proudly presented me with the puller and told me to have a good time with it.  All it does it hook the underside of the seal and you leverage it out of the housing.  The picture above has Alan pretending he is going to pull the seal, but once again, he was just posing for me to take the picture.  Oh well.....

Removing the front output shaft seal

The picture above shows the seal just coming out of the housing.  I was quite impressed at how nicely the seal remained in one piece.  I think I could actually reuse it if I had to.  Luckily, Tera includes a replacement seal with the 4:1 kit so you can pretty much mangle this one to pieces, if you need to.  Just be careful not to bang up the snap ring or the bearing which are both located below the seal.


Here is a great picture of the snap ring that must be removed before the bearing can be removed.  You need to be careful with both of these parts since they will be used in the new rear case.  We tried a pair of snap ring pliers.....a Snap-On pair at that.  But, they weren't the right kind to engage this kind of snap ring and they just couldn't get a bite on the snap ring.  

Removing the front output shaft snap ring

So we resorted to a couple of screwdrivers and surprisingly, it worked really great!  Take one of the screwdrivers and pry the snap ring away from the wall.  This is pretty easy to do since the ends of the snap ring are cut at an angle that allows you do to this pretty easy.  Once you have it away from the wall (which also means it is partially out of the groove), you can slip another screwdriver under the ring and begin to gently nudge it up the side of the housing wall, as seen in the photo above.  Continue working the snap ring up the wall in kind of a spiral pattern.  You don't want to leave one end still engaged in the groove while the other end is pushing out of the top, as this might cause the ring to crack in half.

Once the ring was out, we used a ball peen hammer and a drift punch and gently tapped on the "outer" race of the bearing assembly (from the opposite side of the bearing as shown in the above photo).  I just walked the punch all the way around the edge of the bearing,  tapping as I went.  In a minute or two, the bearing was out of the housing, good as new.

At this point, we were half way done!  Time to stop and have some lunch, which is just what we did (and you should too!).
