| R.R. 75S (10M) (SL 72 18-7-23) MP 274954s. COMPLETED 2.11.23. STANDARDISATION of CHASSIS PARTS. Date 4.10.23. Description of Parts: FRICTION WASHER FOR PIVOTS. Origin: To increase amount of friction. [Box with X mark] No. 4207 Drawing No. Part List Experimental Test Report: At present 40/50 cars have one fibre friction washer in one pivot. It is proposed to fit friction washers to both pivots and change the material from fibre to lead-bronze. Road Test Report: Adopted by Springfield. We have proved that 40/50 chassis when they have been on the road for a time, are improved by slightly more friction in the steering. It has the disadvantage that the customers first impression of a new car is that the steering is heavy.
