| RR 733 REVISED (10H) (D67) ORIGINAL COMPLETED 18.9.30 STANDARDISATION of CHASSIS PARTS. Description of Parts. GOODRICH ENDLESS CANVAS RUBBER FAN BELT. Origin. To improve the efficiency of the cooling system. Experimental Test Report. We have proved that this gives a better drive when spring loaded and stretches less. We recommend that it is run choc-o-bloc. Road Test Report. Run 10,000 miles on 25-LX. Brooklands tests shew improvement to cooling system. [Table section] P.II. / 20/25 HP. Weight of Old Part.
