I should have listened to Mavaholic and ordered my rearend from Curry. This is turning out to be very frustrating, but with help here I am learning. I think I want 2-3 degrees of negative pinion angle. Using a simple protractor is not working for me. What I have done is run a string from the tailshaft of the trans, kinda like a driveshaft. Then using a level at the pinion I am trying to get a degree. Have any of you used a digital protractor? and is this the direction I should go? Thanks Dan
here is the easiest way: put a protractor/angle finder across the face of the harmonic balancer on the front of the motor. This is the flattest place to measure from. then with the driveshaft removed, turn the yoke so you can put the angle finder vertical across the face of the yoke. Read the angle and subtract the difference. A digital angle finder is much easier because when you put it across teh face of the balancer, you can reset it to 0, then climb under the car and read the actual angle. Good luck!
That would work on the front yoke but I dont think on the back . The angle on the balancer wouldnt be the same as the angle on the back of drive shaft UNLESS the the drive shaft was running perfectly true with the centerline of the driveshaft/transmission . Maybe I am missing something though .
The method I use is very similar to Mavman's, only I lay the angle gage (liquid filled with a pointer, bought at Sears for about $10) on the rear face of the trans. It's a machined surface that's supposed to be perpendicular to the output shaft.
