? about setting up gears in dana60?

i am getting ready to set up my new detroity locker and 4.56 gears in my dana60 frontend. i saved the shims from the old stuff for a starting point but i have a few questions. what is the specs as far as pinion depth and backlash? i have never done this before but i plan on learning. any help or ideas would be appreciated. thanks

Re: ? about setting up gears in dana60?

Email me! IM doing the same thing on a dana 44, maybe we can learn together? ive got some questions too

the pinion depth should be scribed on the end of the pinion, along with the lap/match number that should correspond with the # on teh ring gear.

the backlash is 6-10 thou.
8-10 in/lb pinion bearing preload
110lb/ft ring gear bolt torque
80 lb/ft on the bearing caps

Re: ? about setting up gears in dana60?

how do i correctly measure pinion depth? the 4.10's that came out had +1 etched on the pinion and the 4.56 pinion has +2. what does this mean? i really want to do this my self so i can learn the process. any help is appreciated.

Re: ? about setting up gears in dana60?

a machined flat tool across the bearing caps flat surface, measure from that to the end of the pinion. ( basically measuring from teh centerline of ring gear)
this is pretty simple, but hard to get accurate, you must have the bearings installed, and torque the pinion nut to proper torque to get a true reading.

are you sure your gears say 1 and 2? mine says like 2.562?
I got the instructions from Randys and they help alot, but there are some specifics im still unsure about.

you need to get a book or service manual or maybe a buddy close by to help you a little.

settingthe pinion depth is just the first step, then the backlash must fall within 6-10 thou, then the pinion bearing preload, then the carrier bearing preload, these things must all exist together, or a best compromise between some might have to be made, along with a good pattern.
