Just about to order new bearings for the 500 gearbox and discovered a code I do not understand in the parts book. On the mainshaft there is a bearing (part no 59) That is listed as a 63-32-45/c3 bearing. (No its not a 6332 its the wrong size!) I have tried to google this bearing code with no success and looked for similar in justbearings website with no success.
Is this some sort of special bearing? All the others inthe book have a standard code and are easily available. Any ideas? Failing that I will measure up accurately and order something to match. Quick rough measurements are internal 17mm and external diameter 40. Forgotten the depth and don't want to go back in the garage mid sentence.
Thanks in advance

It's a four point angular contact bearing.

Assuming Morini didn't specify a custom thrust angle, then match it by size to a standard FPAC of the same clearance class. Get a bronze cage if you can.
