I am replacing Wheel/Axle bearings on my 773G. I was trying to get my bearings ahead of time. I have spent hours looking on this site and others for the Timken #s.. There are aftermarket sets you can buy, but the phone support says they don't know the brand of the bearings.. And I prefer Timken..I need them for this weekend. I can get fast shipping from some retailers but need a Timken number.. I am amazed that these numbers are not on this site.. Or maybe it is operator error on my part.. Thanks for any help..
