CAMSHAFT BALANCING CAM - BENSPORT(Codename for 3 1/2-litre Bentley) J.1. The timing of the above cam, as given on LeC.3563, is incorrect. For the timing to agree with the calculated position, the cam requires to be advanced 35° in the direction of its rotation, so that the keyway in the cam should be retarded by 35°. Will you please have the drawings altered so that future experimental cams are timed to agree with the calculated position. Hs {Lord Ernest Hives - Chair} /F.J.Hardy. | ||
