Another dumb R&P question(s)...

[jimf909]

You may recall that last week I asked a n00b R&P question (how much of the tranny needs to be disassembled to R&R an R&P...answer: all of it). I've got a 4spd manual.

My question this week is: does the Ring get installed into the differential?

Reading from this post about the Country Homes Camper 3.27 R&P...

In 2020 we will install this same 3.27 R&P into our differential and after another 60,000 miles we’ll pull it out again to check the durability.

Does the R&P actually get installed into the differential or is it more of a case of the ring being installed on the differential with the pinion engaging the ring ON the diff?

Is the 3.27 for an Auto trans (3.27 sounds really tall for a manual trans which typically have ratios in the 4.5 to 5.8 range) and therefore different from a manual?

Likewise, if a Peloquin is installed, is the ring gear basically removed from the old diff and installed on the Peloquin?

Words may be more helpful than this picture...

No luck yet searching for actual photos.

Thanks.

Okay... here's the pinion, the round gear at the end of the shaft in the BOTTOM LEFT. Is that correct?

The country homes ring and pinion is for an automatic. I’m 90% sure. So that’s of no help to you. What exactly are you asking for? A manual transaxle is built around the pinion shaft pretty much. The only real task you can do with minimal effort and tools is to swap the stock open differential for another type.

Bam! Now I can see it. Thank you.

This post from Gears also shows me the way (the entire thread is remarkably helpful)...

Until next time, those are my R&P questions.

The R&P are a matched set. You can remove the ring without removing the pinion or taking the transmission section apart, but you can't swap another ring in without a matching pinion. The pinion is an integral part of the gear cluster in the transmission section. So, any R&P swap in a manual requires a complete transaxle tear down.

The automatics have entirely separate differential and transmission sections that can be...well, separated. This allows the automatics to have the R&Ps swapped out without having to break into the transmission section. Very different units.

^^^ Thanks. That's helpful in learning about these things.

old_mans thread along with the one from gears was also helpful.
