BENTLEY PROPELLOR SHAFT DAMPER. Our experience on a number of "D" Series Chassis fitted with the above is that the loading should be reduced 50%. Confirming my telephone conversation with you, will you please arrange to obtain some springs which will give this result. In the meantime, we are obtaining the required loading by leaving out 6 of the 12 springs. The above remarks apply to the Bentley Chassis and not to the 20/25HP. | ||
