EFC ORIGINAL RECEIVED. X3743 RE. STANDARDISATION OF PARTS WHICH HAVE RUN 10,000 MILES ON 2.EX CAR. X.3644 There are several new parts which have been run 10,000 miles successfully on the above car and we should like the Works opinion on them before recommending for standardisation. X.3654 1. Oil Retaining Ring solid with Clutch Ring. With the oil retaining ring solid with the clutch ring, it is impracticable to finally turn the clutch cone with the two halves of the flywheel bolted together. We found that the only way we could make it was to grind the conical face on the clutch ring true with the spigot. We do not feel happy in recommending any change in the method of producing our clutches because our experience has always shown that to get a satisfactory clutch is necessary to finally turn the cone on the clutch ring with the flywheel bolted to the crankshaft. The advantages in having the oil retaining ring solid with the clutch ring are that there is no risk of oil leakage like there is at present from the joint, it also gives more clearance for the pedals. X.3530 X.3699 2. Magneto Drive. The Magneto Drive which has been running on 2.EX is one made up with hardy Fabric joints. This has run quite successfully but our impression is that the other new Magneto Drive which we are testing (serrated type) is the better job and more easily produced. It is intended that with the Contd. | ||
