| RR 755 REVISED (10H) (D.C. 777 - 29 - 2 - 28) MS C. LTD 42430 COMPLETED 10. 5. 28 STANDARDISATION of CHASSIS PARTS. Date 24. 3. 28 Description of Parts. 9.5" PENDULUM LEVER WITH OTHERWISE STANDARD STEERING. X No. 7430 8430 Drawing No. Part List Origin. To reduce road shocks and make parking easier. Experimental Test Report. This is exactly the same length of lever that was fitted to 'V' series cars. It gives an overall steering ratio of 15/1 instead of the std. 13/1. Car at Le CanadelHenry Royce's French residence has a ratio of 16 1/4 / 1 Road Test Report. Run 2000 miles on 8-KX heavy closed car. 4000 miles on 15-EX in France. Gives a rather better steering all round for the troubles we mostly encounter. A Scrap and replace at all costs including Chassis already delivered to Customers. (selected) B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. (selected) D Use existing stock Alteration effective on future Chassis.

Eric Platford - Chief Quality Engineer} E.{Mr Elliott - Chief Engineer} 28. 3. 28 Agreed. E.{Mr Elliott - Chief Engineer} Apparently the cure for steering trouble is a low enough ratio and retaining a sufficient measure for self-centering. PN.{Mr Northey} CWB. 4. 4. 28 Agreed. CWB. It is understood that with 15/1 ration 2 1/4 turns of steering wheel are required from lock to lock. HS.{Lord Ernest Hives - Chair} 24. 3. 28 Agreed. Hs.{Lord Ernest Hives - Chair} | ||
