| R.R. 493A (50m) (D.B. 175 25-9-24) J.H.D. EXPERIMENTAL REPORT. -2- Expl. No. REF: GWH{George W. Hancock - Head Chateauroux}1/Crm10. 6. 25. up. Engine guards - as reported, these do not keep the engine clean on either side. On the exhaust side most of the dirt appears to come through the hole allowed for exhaust pipe. We believe that if the flange at this point was made deeper at the front it would tend to throw the dirt clear of the hole. On the O.S. we found that the engine guard did not come within 1/2" of engine case. This allowed a lot of dirt to come through. Also the end louvre should be carried close up to undershield of gearbox. We have got a square end on this undershield, and the dirt hits this and is forced upwards through the louvre. We would suggest that this louvre be carried close to undershield. We also think that it would be better to round the front end of undershield, instead of at present, a square end. This would allow the dirt to get away more rapidly than as at present being piled up in the top corner. The gearbox protects the gearbox O.K. RADIATOR TO L.O.P. F.53320: This is O.K. Radiator shutter and controls to L.O.P. F.53390 - these have worked satisfactorily. DASHBOARD AND BRACKETS. D.{John DeLooze - Company Secretary} type dashboard F.52857, otherwise to L.O.P. F.53341 all supporting bolts to brackets worked loose, also bolts loose holding scuttle. We have tightened all these up. STEERING COLUMN & BOX. New stiffness support tube to Drgs. F.53250/1/2/3/4, otherwise to L.O.P. F.5941. Steering column support bracket on dash - all bolts worked loose. These have been tightened up. Steering box support on frame - both bolts worked loose. These have been thoroughly tightened up. Steering at slow speeds light wobbles on uneven surface of road. At high speeds on good road, steering feels slightly unstayable. On rough roads at high speeds, shocks are felt on steering wheel, but are not to be compared with the shocks received from the MAC.{Mr Macintosh} steering wheel. FRONT AXLE TO L.O.P. G.51820. Friction of pivots modified to M.sch.1996. Leam of pivots O.K. back. Pivots and bearings seem quite O.K. Brake operating shafts G.5162 - fair amount of slack in bearings. Brake drums and shoes in good condition. Slight slack in cross steering tube ball end joints. These have been tightened up. Front O.S. brake bearing hard on toe of lapping shoe. This will have caused steering to pull to O.S. that we reported. We have eased the shoe slightly. N.S.F: hub centre serrations jammed owing to the plating peeling. We have made this O.K. Shafts and bearings in axle operating brakes in good condition. contd :- | ||
