| -5- FAN TO LOP E 77672 The fan bearings have been slack and noisy throughout the test. The fan blades have fouled the radiator controls when the radiator was fully opened. The fan requires dropping to prevent this as the belt stretches. OIL LEVEL INDICATOR LOP E 77669 MODIFIED TO LEC 2672 The indicator has funtioned correctly throughout the test. IGNITION GOVERNOR LOP E 77659 GOVERNOR HOUSING E 77684 MODIFIED FOR OIL DRAIN GROOVES TO V 405 The governor has operated smoothly and evenly. We have not observed any faults. The filter has been examined twice and in each case it was perfectly clean. GEAR BOX & ACTUATING GEAR TO LOP 76764 NS{Norman Scott} 2629-70C SERVO DRIVE TO LOP G 76740 SOLID ENGINE COUPLING TO NS{Norman Scott} 2812 We have had on many occasions had difficulty in changing gear from 2nd to 3rd. It jams when trying to get through the neutral position. On one occasion it was some minutes before the lever could be released. When in third gear there is a knock on acceleration and on retard,this knock is more pronounced than with previous third gears. The oil leaks are slight, very much improved with the drilling of the air vent. The servo gears are noisy, have a very bad retard period and are not passable in their present state for production. The solid engine coupling has given no trouble,it appears to be sound mechanically. Previous trouble with the Reverse is now non-existant. The gears are very good for tone. FLYWHEEL AND CLUTCH TO LOP G 76591 The clutch is smooth in action,no jaggers have developed throughout the test. The clutch is very prone to slip after oiling the clutch universal joint situated in the flywheel. It would appear that the oil retaining groove is not capable of dealing with any excess of oil.This was pointed out in the early stages. The amount of oil put in the shaft has not exceeded 15cc per 2000 miles. We have previously had trouble with the universal joint not having sufficent oil. PROPELLOR SHAFT AND UNIVERSAL JOINTS NS{Norman Scott} 2547 STRENGTHENED TYPE 6" MECHANICS JOINTS USING EXISTING COUPLING FLANGE G 76829 PROPELLOR SHAFT G 76850 WITH OVERSIZE TAPER PINS.TRUNION BEARINGS DRILLED AND GROOVED TO EX 2818 OTHERWISE TO LOP G 76851 The joints have not lost more than approximatly 1% of oil after making the joint faces oil tight. This was accomplished by fitting paper washers and the use of a sealing liquid called Hermetique. | ||
