| RR 755 (10M) (DB{Donald Bastow - Suspensions}130 12-9-24) MS 301225 X/7370 COMPLETED 20.10.26 STANDARDISATION of CHASSIS PARTS. Date 22.9.26 Description of Parts SERVO BALANCE LINKS. X No. 7370 Drawing N sch. No. 2194 Part List G.74852 Origin. To increase area of friction for damping the links. Experimental Test Report. Friction remains more constant with the increased area - load can be definitely set by the castellated nut. Road Test Report. 10,000 miles in France on 12-EX car. Friction of links remained constant with the increased area of load of 50 lbs. at end of lever G.72513 and was found to give the best results i.e. prevent thumping of front brakes.
