AA timken diff
Hi guys, started work on the next project. I'm starting on the diff of a 29 Canadian AA with a timken rear end. A couple questions, does anyone know if there's a ring and pinion assembly available for this application? I've got two sets but one has broke teeth and the other (tho usable) is getting enough wear on the drive side. The ring gear measure 11 1/2" across, 8" centres on the bolts and has a ratio of 34-5 tooth count, (I think that's 5:32) and has a stamping number "H1061A" also "Republic"
The ratio isn't as big a concern as finding one that fits. Also the Hyatt bearing used on the rear side of the diff to steady the pinion is part number 7203 with an external race "OR406". I doubt that will change up or be a serviceable bearing outside of NOS, just wondering about using a high speed ball bearing instead and thoughts? Sent from my iPhone using Tapatalk |

That's a 6.8 : 1 gear set . The gear is part # AAC 100164 and the pinion is AAC 100166.

Thanks for the part numbers, I might be able to find something with those rather than a replacement republic gear number. Wow, my math needs work, that wasn't just a screw up...it was almost biblical. Note to self, next time find a pen/paper, calculator, or just someone who knows what they're doing!

Re: AA timken diff
I am also doing a little work on this same rear end. Is there a parts list available? I’d also like to see an exploded diagram of the front assembly.
