Rolls-Royce Phantom II - Torque Reaction Damper
A super detailing note is available if you want to add the Torque Reaction Damper and Diamond Engine Mount assembly that was installed on all Phantom II engines beginning in Jan 1932. The purpose of the assembly was to reduce excessive twisting of the engine under load. However, it was never included in the RR Pocher kits.

The assembly is complex and, in order to fit it in, you will have to reduce the thickness of the Pocher radiator, which is oversize. How to reduce the thickness is described in Vol. 2 - Chassis of the original RR Build Notes. Click on the button for a copy.
As with the other notes, page space is limited and full screen 'pop-ups' aren't possible, so on this page are some additional photographs. Click on each thumbnail to 'pop-up' a full size window.
This photo shows the location of the end flange for the torque reaction damper cross-member. The flange is squeezed in between the radiator mount (to the right) and the vertical-type shock absorber (if you fit that).
The post to the immediate left of the flange is a connection point for the chassis lube line.
