OK next questions, I am getting ready to setup the gear sets and need to know about carrier bearing preload.
I understand there is a spreader that helps get the carrier in with the correct amount of shims. What does this look like and how do you determin how much you need for extra shims to get the proper preload?
a case spreader looks like a tennis raquet string tensioner on sterroids. 2 large paralell bars with pins in the center that fit in those 2 machined hole on either side of the case. a clamp to hold the pins in the holes, ubolts work well. connecting the 2 bars on one end is an adjustable bar hinged on each end, then the other side is a threaded rod used to apply spreading force to the case.
Honestly I made on a few years ago and don't use it any more. I get the shims as tight as I can drive in with a soft lead mallet and call it good. Factory spec for spreading the case is only .005 before deformation and I can more than .0025 preload on each side easily with a mallet. A couple pry bars on teh ring gear bolts will pull the carrier too. There are lots of my gear set ups running around with no problems using this method but use your judgment.
Hope that helps
Wayne
