how to change a crown wheel and pinion

[bmcecosse]

Section HH of the Workshop manual! Most just swap the complete final drive assembly - plenty available second hand if you don't mind the 'common' ratios of 4.55 and 4.22. The less common 3.9 and the (now) rare 3.7!

iv had a 3.7 ratio diff for 2 years and no one wants it.its been to 2 auto jumbles,and classic car mags..i got it from a austin a35 van.1 owner from new covering 59k miles..i now use it as a door stoper..

[bmcecosse]

Certainly wasn't a 'standard fit' in an A35 van! Are you SURE it's 3.7 ?? Post up the ratio numbers on the gears.
If so - plenty on here will have it from you! In fact - stand back so you don't get crushed in the rush.

the speedo was also out i used a sat-nav for the speedo..now with the 4.22 its fine no more sat-nav..but the car was doing nearly 70 mph and wanted more on the hills it was like a slug....i had the engine rebuilt tho..cool..as the engine that was 848cc was taken out in the 70s...

Well - 11/41 is indeed a 3.7 final drive. Amazed you haven't been inundated with offers........
