| RR 785 REVISED (10H) (DE444 6-10-26) BM. COMPLETED 20.1.27 STANDARDISATION of CHASSIS PARTS. Date 10.1.27 Description of Parts. ALTERATION TO THE SPRINGS IN CROSS STEERING TUBE. X No. 7425 8425 Drawing No. Part List Origin. Found necessary in France to obtain sufficient friction in the steering. Experimental Test Report. This is the minimum amount of friction in the steering to produce stability and to eliminate low speed wobbles. It amounts to 6 lbs. at the wheel rim, front wheels jacked up. Road Test Report. Cross steering tube with these springs in has run 10,000 miles on 12-EX, 7,500 miles of which was in France. Measureable wear on ball .001". Pads in good condition. A Scrap and replace at all costs, including Chassis already delivered to Customers. B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Weight of Old Part. Cost of Old Part. £ Weight of New Part. Cost of New Part. £ Difference per Car. £ Difference per Car. £ Negligible.
