Hi guys,
I would like some advice on setting up the diff carrier taper rollers end float/pre load. When i got my car to restore I pulled the gearbox apart ( I didn't check it)and when I went to reasemble it with new output and diff carrier bearings useing the same shims on the same side the diff locked up solid I had to put 20 thou shim under the main side cover to get the diff to turn. ( pinion backlash is ok) . I removed all of the bearings and removed the seals,these where 8mm wide and i thought the may have been stopping the output bearings from seating properly. I have machined the outside diameter of the old bearings to act as dummys and reassemble it with the same problem, I have removed 3 shims (about 20odd thou) to get it to turn. Reading the Hewland info I have( which I find very vague) it says "Now turn the pinion by hand to test the pe-load,adjust by means of shims untill satisfactory" The big question is what is the "satisfactory" preload. should I remove shims untill I get ,say 10 thou end float and then add 10thou shims plus a certain amount to give a set preload. Can anybody help me please . I hate guessing ,I would much rather have a mesurement to work to instead of "Satisfactory"
