[Fot] Subject: Quaife and 4.1 Installation Issues TR3

[Catpusher at aol.com]

The only problem that I had with 2 Quaifes that I did for other  people was 
that the factory Hand Press collets could not get behind the  side brgs. to 
remove them.
Is the pinion Depth correct?
Who made the 4.1 R & P ?
Quaife problem as mentioned by others?

Amici - I have purchased a new Quaife directly  from Quaife UK, a new 4.11
gear set and a complete set of new bearings for  installation in a Southwick
conversion TR3 differential housing. In what  should have been a relatively
simple installation process has proved to be  one royal PITA. Simply put 
with
the pinion installed with the correct  preload, even with all the shims 
moved
to one side of the carrier there is  no way to get any backlash. 

This has been driving my installer crazy  as they have checked, several
times, all the dimensions, bearing and cage  heights. It appears that the
Quaife cage is 1.2 mm taller than the stock  cage. I have phoned the Quaife
tech line twice and sent a number of e-mails  requesting assistance and
received the following response: "I think that  our diff only fits with the
3.75 ratio directly, the only option will be to  Machine the crown wheel
face."
