Wavetrac Install: Bearing Q's

[shoon]

Any suggestions on how to remove the race (cup) portion of the diff bearing from the housing?

I searched the forums and came up with heat (less than 300 degrees) OR pay a few hundred dollars for the special tool. Not sure what the tool looks like or where I can get it, and don't want to heat the housing unless I have too. I was thinking of trying to drive it out with a punch, but if i miss its gonna score the snot out of the bore for the axle seals.

As far as preloading the new bearings I was going to use the solder method; place solder behind the race (cup), torque case halves together, disassemble, then measure solder with micrometer and add 1 thou' of an inch to the measurement to determine a nominal shim size.
Has anyone done this before, and can you confirm if it works or not?

Furthermore; I do not want to seat the new bearing and have to remove it again if I do not have to; so I was thinking of shaving a little off the sides of the old bearing race and using the old race to get my measurements. The only thing is that I am not sure if the bearings will be 100% identical in size / shape, so im not sure about the accuracy of measuring this way. The old bearings are NGK and the new ones are Timkin's.

Is it possible to reuse the old race (cup) for measurement or is it best to stick with getting my measurement off the new bearing race (cup)?


Thanks in advance!

Shaun,

SHOnut has a good video that shows exactly how to install a differntial. I highly recommend it, as it is worth every penny. http://www.shonutperfomance.com

I would also recommend using the special tool to select the diff shim. I don't think the solder idea is going to work, since the bearing races are pressed in, and you will not get an accurate crush measurement.

If all else fail, I am not that far away in Vancouver, WA. I have all the tools and shims and I could install the Wavetrac if you wanted to bring it down.
