Hi you all!! Since it is almost Halloween I have a great mystery.
Checking parts No. for differential bearings on 1939-1953 MPB, the number is 187434 (3B didn't found the cross reference) I found a Timken cross reference book and guess what, the number doesn't appear there either. On the 1947-1954 MPB the same number appears and also the 7450438. This number doesn't appear in the Timken cross reference. But on both parts books appears a reference to K 11445Z (SKF numbering). On the 1955-1960 MPB the number that appears is the 7450385, with no reference to any bearing and it doesn't appear as well in the Timken Cross Reference. Which shall be the approriate bearings for the differential? Thanks
