model R transmission bearings

Darren from UK · Oct 26, 2012

Hi guys. we have a R with worn out trans bearings. these are hyatt bearings, can they be replaced with normal timken bearings? we have tried bearing folks here in the UK but they can't seem to be bothered! we need differential carrier, primary & secondary counter shaft bearings. Has anyone got any timken part numbers? Thanks in advance.

final drive 47685 47620 need 4 of each
differential 4595 4535 623 612
main-shaft 33821 33890 45221 45290
counter-shaft 39520 39590 45221 45285
these are timken number from the interchange chart in the July-august edition of two-cylinder magazine 2007
i have a R that is being rebuilt from one end to the other. if you can i highly suggest getting a copy of that issue.
