| RR 755 (10M) (DB{Donald Bastow - Suspensions}120 12-9-24) MS 301225 COMPLETED 20.10.26 STANDARDISATION of CHASSIS PARTS. Date 22.9.26 X No. 7205, 8305 Drawing No. Part List Description of Parts: OIL RELIEF VALVE. Origin: To improve reliability. Experimental Test Report: The new design of valve avoids the risk of stick-ing. It is also fitted in a more accessible position. Road Test Report: Run 10,000 miles on 12-EX. No failures during test of oil pressure. This is the first 10,000 miles which has been completed without relief valve having to be dismantled.
