Changing Crown Wheel and Pinion

Is this 3.54 Crown wheel and Pinion:

Essentially a straight swap in a standard +2 3.777 diff or are there other parts that would needed to be changed to accommodate it?

Yes, but it's not straight forward to get the mesh correct - you will need a new crush tube as well to get the pre-load right and IMHO you would be daft not to replace the seals at the same time and, perhaps, the bearing. I seem to recall I replaced the nut as well - ?15 for one nut

I was lucky and obtained a 3:54 CW&P from one of the Escort boys for ?30 - works a treat.

3:77 is quite sort after by the Escort crowd and stock racers so you might be able to do a swap?

Somone on here recently posted about a firm in Chesterfield who provided a good diff service.

Ok, Thanks Jon!

I'm guessing that a 3.54 from an Escort is the same as the burton CW&P and would still need the other relevant changes made (Crush tube, Pre-Load etc.)?

Yes, the CW&P is a Ford item as used in the Ford English axle - completely interchangeable.

The 3.77 CW&P was used in the Escort Mexico and, unless I'm mistaken, Escort TC and RS1600 so it's actually quite rare and desirable.

The 3.54 was used in the RS2000
