-2- we have had no further trouble with the pistons. GOVERNOR CONTROL. It was requested at the beginning of the test, to cut out the action of the governor. This was done by disconnecting the lever inside the governor case. A stop was fitted to the throttle for slow running and starting purposes. We have not found anything detrimental in running the engine, or control of the engine, by deletion of the governor. CLUTCH TRANSMISSION. HARDY COUPLING. The Hardy Coupling shows definite signs of fatigue at the finish of 3000 miles. The fabric has become fractured at the edges of the plate where attached to the spiders. There is not the usual bulging effect. There is no record of the coupling having been changed whilst the car was at the Works, therefore its total mileage is 17,000. GEARBOX. We have had the cover s off the gearbox and can see no defects. The change speed selectors, synchromesh mechanism, and gears, look to be in a perfect condition. TECALEMIT FILTER. The Tecalemit fitted for experimental purposes only, is very effective in collecting the carbon sludge. The felt component fitted is the 12 star type. It was thought that it might cause too large a back pressure when the oil was cold, we therefore fitted two oil gauges to give pressure readings of oil entering and outlet. The pressures have never varied more than 3 lbs with the oil cool. We have not cleaned the filter so that its condition may be examined by E.{Mr Elliott - Chief Engineer} who is interested in the experiment. The oil relay filter was perfectly clear at the finish of the mileage. MAGNETO. NEW WATFORD MAGNETO NO.130565. This was fitted to replace the old type magneto taken off. The contact points were in a very good condition, but had lost .006" of the gap setting. This apparently had been caused by the wear of the pad. The rocker arm and bearing were in good condition. | ||
