The Dreaded Ring And Pinion Depth Measurements and Why You Should Care

[@georgebourdeison1750]

Great video . It would be very interesting to make a video how to install the shafts on the upgraded one piece bearing retainer. Thanks for the work you make

[@GarageTimeAutoResto]

Will do on the next one. It will be a bit harder pushing the bearings on. Did you see the pic of my new parts? I'm excited

[@GarageTimeAutoResto]

Also the 356 trans has a one piece retainer oddly enough.

[@georgebourdeison1750]

Of course i saw them . New parts 5 more years to owr lifes. Keep on the good work.

[@yueibm]

That's impressive! I read up a lot of info from Grady Clay on the early 911/912 and Pelican forums.

[@GarageTimeAutoResto]

Great info on Pelican always. Also the Zimmerman tutorial is well done. We are living in the information overload age!

[@johnvaluk1401]

Thank you Tom. To bad about that bearing spinning. Ugh. Enjoy your videos very much. Have good Easter if you celebrate.

[@GarageTimeAutoResto]

I know bummer right. That differential doesn't look good. I plan to buy a limited slip differential for my other Transaxle so I can rob the differential from that transmission in the blue box that I bought disassembled. The ends on that one are nice. Happy easter!

[@isallaboutthebicycle1126]

Very informative.

[@jeffharrison5265]

Great work as always! Always enjoy.

[@GarageTimeAutoResto]

Thanks Jeff!

[@walterkucharski4790]

Great tutorial Tom as always.

[@GarageTimeAutoResto]

Ha ha, don't tell anyone I've never built a 915 before. 😃

[@carl545marchbanks4]

Love the garage diy build!

[@GarageTimeAutoResto]

Thanks! Anyone can do this

[@Wanix11]

Explained very well.

[@FriendM2010]

Fascinating! Nice MacGyver on the diy depth gauge do-la-bob to measure pinion depth, lash, etc. It may pay for me to someday learn the gearbox rebuild for my 911. I saw a place in AZ will go through the whole gearbox for 1k. I thought that’s fair. Then I keep hearing peeps come out of the place with a 10k+ final invoice 🥴. I have all factory manuals, it would be the tools, presses and gear pullers to buy. Nice work! Must of been real exciting doing your first gearbox. 🤓😂.

[@GarageTimeAutoResto]

$1k to take apart and then invoice for a bunch of new parts is a good business strategy, ha ha.

[@GregsGarage]

Again, awesome stuff!

[@georgebourdeison1750]

Hi i was wondering about the diff housing. a good machinist could bring down a few millimeters the damage surface and then put a hardened ring ideally from a bearing case with the cold hot and glue method . And after machining the new ring to the bearing spec installing the new bearing. I hope you understand what i want to say. What do you thing about this method?

[@k708388]

hey tom why dont you put the race on dry ice too?

[@GarageTimeAutoResto]

That works. Just lazy I guess plus I knew the press fit wasn't that tight already.

[@davidmaldonado4849]

Tom do you do 993 transmission video???

[@GarageTimeAutoResto]

No, only 741 and 915

[@jwright650]

Hope you have several diffs to set up to make all of the time spent making that tool to measure the pinion depth worth it. I know that took some effort to make that tool and to get it set up.

[@GarageTimeAutoResto]

Is three enough?

[@jwright650]

With tools like many of yours, the more you are able to use them, the more they pay for themselves.

[@GarageTimeAutoResto]

Agree! I have toolbox of stuff just waiting

[@911engineguy]

How do you set/zero the dial indicator?

[@GarageTimeAutoResto]

Guage blocks to the flat surface milled into the carrier.

[@Vintageguy73]

What do you calibrate or “zero” your indicator to?

[@GarageTimeAutoResto]

I have a guage block that touches the milled flat surface of the diff carrier and the plunger. Actually it's two pin guages and a mill parallel laid on top. That is how I calibrate the mitutoyo digital dial indicator.
