I recently bought a pair of bearings from England to freshen up the diff centre. However these bearings are somewhat smaller those already in the diff.
My question: is there a small size diff centre that takes smaller bearings.
the 2L LSD diffs have different bearings than the non LSD diffs, is yours an LSD type?
The 1750 and earlier diffs are smaller than the 2l diffs - are there threaded retainers on the axles for the wheel bearings?
Yes I have threaded retainers on the axles. It appears I have a 2L diff in my series 2 1750.
Threaded retainers is the early small diff - I don't believe early axles fit the 2l diff - so it's probably the correct unit for your 1750.
2l cars had shrink on retainers.
What's the Internal Diameter of your bearings? 38mm is the 1300/1600/1750 inner bearings, 41.2mm ID is 2l LSD.
Thanks for the info "La Strega". I appreciate your help.
Journals on the diff centre are 38 mm. However my bearings (SKF BR30207) which I bought as diff bearings measure 35mm. I think I have been diddled by seller. See link.

No worries I will order new ones
Thanks again
This is why i try to deal with Alfa people (Avanti/Classic Alfa etc) rather than random ebay sellers - if it does wind up being the wrong part, they'll sort it out...
