Banjo carrier preload problem

Thanks guys, I did run a flat file across the center and both axle halve flanges and did turn up a hi spot or two from some previous to me chisel work.

It did take quite a bit of force removing and pressing the bearings so I think I am good there.
 
HI Tom,

The torque wrench goes to 20 inch lbs then once the carrier is turning drops down to 14-16 inch lbs, does this sounds right?

Thanks for all your feedback
Tom

My experience has been that paper gaskets do not equate with metal shims. The paper will crush down, the metal won't. taking a total of .040 off the carrier hubs does not seem right to me. It seems excessive. I have never had to take a cut on a carrier. I only suggested it as a means to reduce the number of gaskets you were concerned about.

I also wonder about the torque wrench you are using. I use a dial indicator torque wrench and the reading I am looking for is after I overcome the inertia and have the bearings turning.

Nothing wrong with the torque wrench you are using for preload testing. 20 inch pounds is your reading to overcome the stiction to get it moving. Your 14-16 inch pounds is your actual preload drag.

a model A diff can be done by feel if you have experience in these things

I agree Mitch. Trouble is, most of us don't know what the correct feel is. I just redid the differential on my Phaeton early this summer. I purchased a used inch-pound wrench to verify what I thought might be okay. I was in the range and the wrench gave me the good feeling of knowing for sure.
Now 80# to 85# for the mains...I can hit that every time with my breaker bar because of the number of engines I do. Experience...goes a long way!
Good Day!
