| - 3 - Controls. The accelerator countershaft also requires attention. Considerable loss of motion has occured through these bearings having worn. Inlet pipe. We have had no trouble with inlet pipe, it has remained in good condition. Exhaust manifold pipe & fittings. The exhaust manifold is still in good condition. We have had towards the close of the test an exhaust blow developp from the center joint, and it became necessary to replace the copper asbestos washer. The exhaust pipe remained O.K. since fitting the stiffer flange to pipe as reported. Engine suspension. The engine suspension has remained firm after our attention to the brackets. The rear suspension has given no trouble, bolts have remained tight; brackets are O.K. Carburettor & fittings. Examination of filters at end of run, very little dirt was found. Carburettor has not given us any trouble on the road throughout the test, but flooding has always occured after stopping running. Very little wear has taken place in the carburettor units. Fan bracket & fan belt. The fan bracket has remained O.K. There has been no trouble with fan. It has been necessary to take two links out of fan belt. Magneto & drive. X3551 X5790 Magneto and drive have remained in good condition throughout the test. Dynamo. X4610 X5660 The dynamo has functioned satisfactory throughout the test. The commutator and brush gear has been cleaned once after a slight sing had developped. Examination at finish of the test; they were in good condition. Oil pump. We have had no further trouble with the oil pressure after fitting up pump with two holes in each gear for lubricating it's bearings. We still get a drop in pressure after braking, but it immediately builds up upon acceleration. | ||
