3.48 Crown Wheel & Pinion

[spider]

Hi fellow Auto-ers,

I'm looking for a Crown Wheel and Pinion from an early Morris (and Austin?) 1100 Auto gearbox. The ratio is 3.48:1 and I think the tooth count is 73 / 21.

Is anybody able to assist or suggest somewhere who may have them?

Thanks kindly in advance.

Hi taunopalo,

A sincere thanks for reading my wanted post however what I am after is rather rare it would seem.

I think it fair to say that 99% of the auto gearboxes made had the 3.27 diff, that you've kindly offered and I do already have one of these.

What I was looking for would fall in that 1%!!

The ratio fitted to the early Morris 1100 (and Austin?) was 3.48:1 and as best as I can work out, the tooth count was 73 / 21. I have been given some part numbers but they maybe incorrect, so once I confirm, I'll post those up.

It was only about the first 10 000 Morris 1100 Auto's produced that had these diffs.

Cheers
