This is also true when replacing the bearings as they are so precisely made that the pinion depth will be the same as originally set. But those companies don't want to support something out of the box for their $100 tool which I understand.īut in the case of replacing just a carrier, their should be no need to adjust the pinion depth. Once you know that, you can measure from the mating surface to the pinion head to figure what dimensions you are working with. The universal gauge uses the measurement from the cap mating surface to the bottom of the bearing bore minus the radius of the bearing race to establish where the centerline of the axle is in relation to the cap mating surface. You might have to use different pointers or extensions on the dial indicator to get where you need to go. (Ha Ha!) but they lack any documentation on what specs/dimensions would be for an R200. The universal pinion depth gauges will work universally. I know we have been discussing this on PM, but figured I would post some here. Feels like i am down to those two options Edited Novemby perzn hopefully i can get MikeC's input on which tool he used or maybe a good shim size to start off with and then i can play the guessing game with multiple times of assembling and disassembling to get the right gear pattern. proform cant be used on our diffs according to proform, im curious on what MikeC used, i also found a universal tool from powerhouse around $190 and central tools universal tool which can range from $540 to $740. Thanks jon, well, i purchased the r200 used and slapped on the obx, i just cant figure out the pinion depth with out some kind of tool. Really though the way that works is you start with a diff that has the pinion depth set correctly, then you pull the pinion and put a new one in and set the depth back to what you had before.įor your situation I'd just fix it with the pattern. I know MikeC has used a pinion depth gauge on an R200, and I think probably any of the tools will work if you get (or make) the right adapter. Even when swapping from one gear ratio to another, the pinion depth shim usually doesn't change much.
Generally speaking the pinion depth doesn't change unless you pull it out and change the shims. Check the FSM to make sure, but I think I'm right. Your help is greatly appreciated, thanks Edited Novemby perzn Heres a link for a proform tool setup seems legit but would like someones input I know the kentmore tools would cost me over a grand, but what options do i have to set pinion depth? can i use proforms pinion depth tool? has anyone had experience with this tool on the r200? or suggest a different tool? a Z shop quoted $550 which i think is pretty high.
I bought all of the seals and bearings including the pinion pilot bearing special ordered from nissan. I checked the gear pattern with gear compound and According to the pattern my pinion depth is far from the ring gear and backlash is correct. The diff was making noises from +45 mph and up on coast and drive. I installed an obx quaife(i already swapped the internal helical gears in the obx), i installed the side bearing caps and shims in the correct places. I bought a r200 from a 280z, 3.545 gear ratio. Hey guys, i have been doing alot of research and i have a few questions.
