Ring and Pinion Adjustment - 930
 

I am replacing the ring and pinion in my 930 transaxle. The replacement is low mileage and includes a Limited Slip Differential. The factory workshop manuals describe an adjustment process that requires specialized tools and “know how”. What are my options for adjusting the ring and pinion? Do I take it to a specialist? Is there a way to do this myself?

take it (the advice) from the man whose threads I was pointing you to (Noah).

Is it feasible to make the adjustments based on marking compound patterns?

please see the links in my first post on this thread, do they answer your question?

Hi Andy,

Yes, the links to Noah's postings helped immensely. He explained much of the process needed to ensure correct ring and pinion adjustment. However, I would like to complete my project and a trip to a transmission specialist will only delay things further. This time around I may just reassemble the transaxle with the original ring and pinion along with new synchro components. Next time it is apart I can tackle the limited slip upgrade and that will give me time to approach it better. Thanks for helping.

sure; did you ask the question about marking compound patterns before or after reading Noah's links? maybe I misunderstood the question.

I assume that you are saying you can reassemble with the original parts for now and avoid this adjustment process. If you are on a timeline I do think that would be a good option.

I asked the question about the marking compound after reading Noah' s links. It looks like he used the process detailed in the workshop manuals and then made sure it was correct with the marking compound. My question was if I would be able to achieve the same results by using marking compound only. It would take several iterations to get the correct number of shims on the bearing flange for the pinion adjustment. But now that I am writing this I think I would be omitting the centering adjustment of the ring gear which is the starting point for the process. Does this make sense?

Thus in an effort to get the car back on the road, I am now thinking about reassembling the transaxle with the original ring, pinion, and differential. These parts were working fine. The sliders and dog teeth were quite worn and I will be replacing those. I also have a limited slip differential with ring and pinion that has low miles that I was hoping to get installed. I am now considering doing this later.

I apologize for my prior response, it appears I am unqualified to answer your specific question, and misunderstood it. you might send a PM to Noah to bring his attention to your question. I don't think he's in this forum all that often.
