b31 crankshaft bearings

[EDDIE SIMPSON]

 the original b31 crankshaft bearings are now superseeded by SKF , NGK,  and others. but i m unsure as to whether i need c3 or cn tolerances with any of the three bearings. i ve also seen MRJA bearings the same sizes [ 1 1/8 and 7/8 ] but which suffix is correct? any recommendations?

get in touch with Darren Wrudd. He runs a bearing company and has been very helpful in supplying quality bearings to me and many others.

And a 'Wrudd'y good firm they are too... local to me. Have dealt with them many times for various projects at home and at work and they've always been very helpful indeed.
