pinion angle?
put on a set of Cal-Tracs. need to know what is the best pinion angle?
Specs. 56 Nomad, leaf springs [6 'cause its a wagon] spring pads are 6" long. 9/16" U-bolts. approx. 1725lbs on rear. motor mounted solid, so the trans angle is NOT adjustable.
right now the 4speed to 'shaft is 2degrees. the pinion is about 1/2degrees up from level and there is 2 degrees difference.
I have degrees shims. if I put the pinion down -2degrees, that would make 4 degrees total at the rear. setting the front would change very little. at launch, the front angle should increase approx 2 degrees [front/body rise].
in high gear the front drops down. in theory then, the front angle would be 2+ degrees difference and the rear would be 2 1/2 degrees the opposite direction. sound right or no?
with the long spring pads, I cant see the pinion turning up very much. 6degrees down would be a lot, I think!
thoughts?
thanks Rod in AZ
