D44 Overhaul

 

With the bearing retainer out of the way, the next step was the bearing itself.  Both of the bearings (on each axle) already had the outer race loose, so I just slipped it off.  Had it not been so, I would have cut this off with the Dremel disc as well.

I started on the bearing, cutting through each "layer" of it and peeling off a piece at a time.  In the above pic, I have just finished cutting this part and found that a screwdriver was just what the doctor ordered to pry it off. 

Next was the cage part of the bearing...the part that holds the rollers all in the right spots.  That was quite easy to cut through.  It took about a 1 minute with the disc, maybe less.  

The screwdriver once again proved to be the right tool to remove the cage.  Watch out for those razor sharp edges that the cutting disc will leave behind.  You'll slice your finger if you get it in there and try to peal the metal out of the way by hand.

The last piece to be removed was that part of the bearing assembly that fits directly on the shaft.  The pic above shows how I did this one.  First, push the seal down and out of the way and then make your cut in line with the shaft, just like you did on the bearing retainer.  Be careful not to cut into the axle shaft.  Take your time and slow cut through the metal.  Stop fairly often and see how close you are getting to the shaft.  

As you can see in the pic above, a nice clean cut can be made without nicking the shaft.  Take your time and yours will come out this nicely too.

This one came apart on the first whack with the hammer and chisel.  Here is the chisel, still in position.  You can see that the gap has widened significantly and this is more than enough to allow you to slip it off the shaft.  Don't pull the chisel out until you have it off the shaft.  If you remove it right now, the collar will snap back together and you'll need to pry it apart again with the chisel.
