I am rebuilding the rear end of the old ford (9.75LS 3.55 gears)pickup. The head/inner pinion bearing let loose, no gear oil, where did it go? Short story, I need a way to calculate the pinion depth.
I am installing a replacement OEM 3.55 Gear set without any checking distance markings.
The original shims were destroyed when the inner pinion bearing failed. The bearing itself was unrecognizable except for the outer race. Normally I would simply hone the inner pinion bearing's inner race until the bearing could be slip fit on the pinion shaft and go from there. See Pics.
I fear that if I have to install and remove the inner pinion bearing several times to accommodate shim addition/deletion that it would be ruined
Normally will hone the inside race of the Pinion head bearing to a slip fit only for setup of the new Pinion's depth. It would then be replaced by the new bearing and race along with the tail bearing, carrier bearings, wheel bearings, and seals.
However not this time. Pinion depth gauges are rather expensive and complicated even for most pros.
Ratech make a very accurate and affordable Pinion Setting Tool at around $30.00 but not for the 9.75.
Randy's ring and pinion Sells Set up bearings that are prehoned, nonreturnable and also a bit pricey.
My math and machinist skills are not what they used to be. Just cant seem to work out the specs/measurements into something useable. My hard drive is too dependent on the one in the laptop. L O L
