| -10- Rm{William Robotham - Chief Engineer}/IDH.4/AP.3.9.37 General Notes on Chassis continued The brakes were powerful, and light and progressive in operation, and generally acceptable under all conditions. Under extreme conditions the near side front brake did more than its intended share of the work and eventually the liner cracked at two of the four locating keys. The liner was originally made for eight keys, which are now to be fitted, and might have prevented the failure. Apart from this defect the brakes were exceptionally good. ELECTRICAL EQUIPMENT. Instrument Board LOP.DW.191. RR.Sch.1007 Dimmer Switch. Modified Lucas petrol pump switch. The range of the dimmer switch was not satisfactory and generally inferior to that fitted to 39-IX. in France. No trouble was experienced with the pump switch. Dynamo. Bearing Brackets LOP.D.54768 Failure of the roller bearing at the commutator end was experienced apparently due to lack of lubrication or provision for same. This was not the final scheme. Horns, Lamps & Fittings LOP.DW.184 Lucas W.T.13 Horns, Standard Production Lucas R.K.type headlamps. The horns were unusually good for the type. The new type lamps gave a good driving light for straight roads but lacked intensity at the sides of the road. The casings were not sufficiently dust proof. The ornamental points on the front require modification to facilitate the cleaning of the glass. These faults have been taken up with Lucas by the electrical section. Klaxon Windscreen Wipers. Oil leaks along the spindle of the O.S. operating knob were experienced. This gets on the driver's hands or gloves and is most objectionable. continued | ||
