I did the same. Its an ATB identical to a Quaife rather than a torsen, stronger in theory. Bought a diff for it to go in and still ended up cheaper than a used 20 yr old torsen!

Oh I havent fitted it yet so theres nothing on my thread. I just figured 200whp would overcome my 1.6 diff in short order so I better get all the 1.8 bits for the exchange. :D

I just wanted a bit more predictability and traction.

So here are the casing parts and flange all cleaned and painted ready for rebuilding.



I cleaned off the calcification on the aluminium case by immersing it in 18 litres of Tesco "cheapo diabetes rot you teeth coke" (4.95) and used a fish tank water heater in the hope of aiding the process along.



I could of had it bead blasted but I was interested to see if this worked. :D Took the best part of a week but didn't have to scrub at it at all.

I cleaned up the cast iron with electrolysis which as always worked brilliantly. Just a jet wash and blow dry and it was ready for paint.



I bought a external 7-8" micrometer off ebay and I have calibrated it with a 12" digital micrometer today. I'm following this guide for setup of the new diff side bearings.

Domestic Science for me this afternoon.

Take one diff and place in freezer. Unwrap new bearings and rewrap in tinfoil. Place bearings on top shelf of a preheated oven and heat for 1 hour at 250˚C. Remove diff from freezer and drop bearings on to each end using liberal amounts WD40.

You won't notice the bad weather. You will be paying too much attention to every noise squeak and rattle in case something is going to fall off.

Remember to take loads of cable ties etc and electricians tape for the test
Good luck.
