I'm finally ready to buy my gears and lockers for the crawler but have one problem before ordering.
I bought a used d60 5:13 r&p that I can't figure out what it is so I can't order the right carrier for what axle?
It is a Precision Gear and the ring gear is stamped 60D 513 R. The pinion is stamped 60D 513 P. My first assumtion was that R meant RING and P meant Pinion - but that would be too easy and it does not. I have contacted Precision 3 times and finally got someone today who actually cared and tried to help.
Here's my problem... the R means REVERSE which would work for my front HP 60, but every tech article I read says that the gears should rotate counter clockwise for a reverse ring gear (and vice versa for a standard cut)- mine are clockwise (like a standard cut) cratchhe: Precision swears that the R is REVERSE and that it doesn't matter which way the spiral is.
When I got home I pulled my front diff cover and sure enough the stock ring gear is counter clockwise making me believe that the R does not mean Reverse. They say that the P on the pinion means "Pro series" which is for drag racing applications. In the front that would be good, but not so sure for the rear cratchhe:
I'm tempted to buy both r&p's now and scratch this one I have, but then again it's an expensive set that I'd love to take advantage of and not have to buy another. IF it will work in the rear, I wonder what carrier size to get. Precision says a 4.10 and down, but I can't rely on their info much now.
Here are a few pics of the ring gear and the stock one in the front diff now.
