| RR 78B (10H) (30408, 21-4-32) BM. 3/8382 4. COMPLETED 14.2.33. STANDARDISATION of CHASSIS PARTS. Date: 6.9.32. X No. 7300 Drawing No. Part List Description of Parts: CLUTCH SPRINGS Hs.{Lord Ernest Hives - Chair}652, CLUTCH PEDAL F.84379 CLUTCH FINGERS Hs.{Lord Ernest Hives - Chair}666, CLUTCH OPERATING LEVER Hs.{Lord Ernest Hives - Chair}667. Origin: To enable 15% stronger clutch springs to be used, thereby reducing wear of the fabrics, without increasing the clutch pedal pressure. Experimental Test Report: Springs were fitted to 19-EX. 10,000 miles trial and eliminated the wear that was occurring with the standard springs. Road Test Report: Complete scheme fitted to 58-GN.
