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. 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.
