Title: How many teeth...?
Post by: kev131 on July 01, 2013, 04:56:34 PM
How many teeth in the crown/pinion set for a Fiat differential fitted to a 131 Sport?

I have a chance to buy a secondhand one and the seller describes it as 10/41.

Can anyone confirm please?

Cheers

Kev

I thought it was a 39  for a sport and a super is a 41.

It shows 3.9 on that data sheet I put on here as well.  I was wondering if the pinion failures were due to fatigue, that being the case, a CWP from a small engine may be better,  Like the 3.9 from the 1600 sohc or 1600 ohv engines.
