Date 22.9.26 No. 7370 Drawing No. Sch. 2194 Part No. G.74852 List 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. Description of Parts: SERVO BALANCE LINKS. 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 a 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.
