Origin. Better accessibility of the brushes. X No. 4626 Drawing No. Part 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 Experimental Test Report. With the present standard dynamo position it is impossible to inspect the control brush without removing the dynamo. The proposed modification is to rotate the dynamo 28º in its fixing. See attached EFC5.2.25. Road Test Report. Run on 7-G-11 4096 miles No trouble. Brushes can now all be inspected. Weight of Old Part. Weight of New Part. Difference per Car.
