Subject: Re: V12 Wheel Bearings
The "Motor Trader" Service Data for the V12, dated September 1939, states that (front) "Wheel bearings are roller outer, ball inner, no adjustment.".
So Pete, yours could have been modified to taper roller at some time in its life.
I have a spare copy of the V12 Service Data, original so the photos are clearer than the club copy. As near as one can get to a condensed workshop manual, £10 +p&p (shameless plug!).
