GermanMonte Posted December 17, 2017 Share Posted December 17, 2017 Hello from Germany, I'm opening this topic because I'm looking for some advice from the more experienced guys when it comes to ring and pinion gears. Just lately I got a new ring and pinion gear set from US Gear for my 1971 Monte. It's a 4.11 ratio for 3 series carriers, sotting behind a 200-4R transmission. US Gear calls for a pinion depth of 2.853" and backlash between 0.008-0.012". With my pinion depth gauge I managed to dial it in at 2.852" with a total shim thickness of 0.036" behind the pinion. Backlash is set at 0.010. This is how the pattern looks like: I know it's a bit toe heavy on the drive side, but with the 427 sbc up front it sure doesn't hurt to have it set up like this. What do y'all think about the pattern? Improvements required? Thanks! Robert Quote Link to comment Share on other sites More sharing options...
lastss Posted December 25, 2017 Share Posted December 25, 2017 We’re did you buy the tool set up for measuring the pinion depth? Quote Link to comment Share on other sites More sharing options...
GermanMonte Posted December 26, 2017 Author Share Posted December 26, 2017 I built the tool at work, since I wasn't willing to spend a [censored]load of money on something I only need once in a decade. It works very well, but you have to calibrate the dial with gauge blocks to a known length / depth before you can use it. Got the gear set dialed in in the meantime. Now waiting for spring to arrive to go on the first test drive. 1 Quote Link to comment Share on other sites More sharing options...
