This seal has to come out. Every time you pack the bearings you have to destroy a seal
and put a new one in, its just the way works. There are actually two different ways of doing
it, I know that there is a special tool for it, I dont have it, most people dont. What
I like to do is take a punch and push this in a little bit, or actually make a hole in
it, so it pulls the seal away from the edge where you can stick a screwdriver in there,
tap it in a few times and pop it out. It is a little bit less stressful on the bearing.
The other way of doing it, if you dont have that, is to take a wooden stake or something
like the handle of this and go in though there and beat it out that way. It puts a lot of
wear and tear on the bearing, but its another way of doing it. I dont know if you can see
there or not how I punched it in and it brought the seal away from the edge. And that is where
we will try to work in our screwdriver. There we go.
We will go ahead and get the bearing out and wipe it down real fast. Makes it a little
bit easier to see, rotate the bearing cage, look for anything that bounces up and down
too much. This is almost a continuous line so I think the cage is pretty good on this
one. So we will just keep cleaning it up until it spins freely. Im looking for little nicks
or stuff like that. Sometimes you can see a little bit of wear, it is like a dark band
here, light band here, dark band here. For the most part that is kind of acceptable,
it is not perfect, but in this case I think it will be fine. If its really dark you definitely
want to change it out because that part of the bearing, this actual roller got overheated,
but this one looks pretty darn good. Then you have to clean out this hub here. Here
is something you might want to take a look at. See these marks on the race. Usually you
see that when there is too much weigh that has been sitting on the bearings, and it sat
there for a while. So it made an imprint and you get these dark bands in there. With something
like that, you probably want to go ahead and replace the race at this point, and since
you replace the race you usually get new bearings with it. So we will go ahead and take out
the races here, and just rebuild the hub at this point. Weve got to take out the races.
So what weve got to do is catch the back edge of this and force it out. Couple of different
ways of doing it, most people just use a nice wide screwdriver and catch the edge of it
and wail away. You go alternating sides, just work it out both sides. Another way of doing
it is if youve got a piece of pipe like this, where it catches most of, or bigger chunk
of the circle and then we have more force going down on it to push down on one side
or the other. I like to start it off with a screwdriver and then finish up with that.
Couple more times. And theres the old race. Dont throw this away because well need this
to push the new one back in. We will set that to the side and we will drive the inner race
out through the back side.
