| -2- Flywheel and Clutch. - The automatic clutch spigot lubrication caused trouble as it was found to be erratic in behaviour. We have temporarily reverted to the original scheme whilst we find out how we can control the automatic arrangement. The slipping of the clutch which was reported on 19-GIV was largely due to oil getting on the fabric. CHASSIS. Radiator. No unusual deposit was found in the radiator which was free from leaks apart from the slight one reported at the tank joint at 6,000 miles. Front Axle. - On the whole the front axle showed signs of being rather under lubricated, more particularly in the section of the axle beyond the felt filters which protect the pivot pins. The only bearings which were actually dry were those of the brake camshaft. We have tried taking out the felt filters on the car now running in France but the result of this was to flood the pivots with oil. Hancock reports that 19-GIV front axle was not short of oil during the 10,000 mile test and we therefore deduce that the Bijur pump may not have been operating consistently after the car left France. The front axle beyond the filter pads very quickly dries up if the Bijur pump is not operating consistently. The cross steering tube balls were sufficiently lubricated to be free from score marks, except in one case where the ball had picked up slightly on the neck of the pad. The front brake actuating shafts were lubricated at the points where the Bijur supply oil, but the central section of these shafts were rusted due to the water getting in. This has been eliminated by packing the centre of these shafts with grease. Front Road Springs. - Lubrication good except for the off side spring rear half which was rather dry. Rear Road Springs. - Lubrication good except for the off side spring rear half which was rather poor. | ||
