| To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} x3806 10.8.34. Chassis Lubrication Meter Valves and Junction Bodies. Mr. Pitt of Luvax Ltd. called re the above yesterday. At present, when the valve is screwed into the junction body, the bottom thread is stripped off when attempting to make a seating on the cone shaped bottom of the junction body. Mr. Pitt is having twelve valves sent to us, these will be slightly chamfered to prevent the threads from stripping and we have agreed to try this scheme out before changing to an entirely different method that would incur more expense. It would be interesting to remove the junction bodies and valves from a car which has been running for some time to see whether any of the valves are blocked and if so whether the blockage is caused by stripped threads or scale from the pipes. Petrol Reserve Warning Light on 1-B-IV. We have tried this scheme out but with no satisfactory results. The car was run until reserve level was reached (this was checked by tap). After coming on to reserve the warning light came on but not permanently and it was not until there was only one gallon in the tank that the light became permanent. The method of making contact is by no means definite enough. The contacts are mounted on copper strips which do not spring back to their original positions when the tank is filled, hence we get a variation of warning to the extent of perhaps as much as one gallon.
