Rum/FD.{Frank Dodd - Bodies} Handwritten: GCD1481 14/4 Handwritten: 400 Rm.{William Robotham - Chief Engineer}20/ML.19.4.40. 15 PRODUCTION B.V's Handwritten: A.K. 15 B.V's are being fitted with bodies and sold to customers. The first car is now completed and will be run by Lp.{Mr Lappin} Since the specification for these cars was circulated a number of faults have shown up and cures for these are now known. We should therefore compile a summary of the modifications necessary to these chassis before they are handed over to customers, to prevent a recurrence of the troubles encountered experimentally. Items which I can remember are : Handwritten: MWH 1. Increased clearance to the rear brake linkage. Handwritten: FJH{Fred J. Hardy - Chief Dev. Engineer} 2. Modified oil feed to the clutch thrust race. Handwritten: TAS{T. Allan Swinden} 3. Starter carburettor modified to prevent freezing. Handwritten: Clm{D. D. Clapham} 4. Procedure to prevent front shock absorbers becoming ineffective. also remove end clearance. Handwritten: RC{R. Childs} 5. Treatment required to ensure that speedometer and rev. counter drives are not noisy. Handwritten: FJH{Fred J. Hardy - Chief Dev. Engineer} 6. Propellor shaft rubber centre bearing. There are probably quite a lot of other points. Will you please compile a complete list and let me have it to hand to Reid. Rm.{William Robotham - Chief Engineer} P.T.O. | ||
