| -7- Cont'd. {John DeLooze - Company Secretary} 106 The coil started to cause mis-fires after a milage of approximately 8,000 and after a further 700 miles it would not fire the mixture. Test taken on an open circuit the spark was very poor. A spare coil fitted was OK. The coil was sent back to Derby for investigation. Remarks: Will Mr Davis discuss this matter with EFC. {E. Fowler Clarke - Electrical Engineer} and see if it is a standard coil, if not, where it differs, and where it failed. (19) PRESS BUTTON SWITCH LOP D.72088 LEC.2641. The press button switch required considerable more pressure to operate than previous push switches. We much prefer the lighter touch. Remarks: We have instructed an earlier form for production. (20) ENOTS FILTER. The one feature which we take exception to with the Enots filter is the use of fibre washers behind the unions. These joints have on and off leaked. Remarks: We should use soft aluminium washers in place of fibre washers if feasible. Will Mr Booth please let me see actual piece. (21) BIJUR SYSTEM CASTROL 'R' OIL USED THROUGHOUT THE TEST. NEW PUMP SENT OUT AND FITTED. We had several Bijurs fail to pass sufficient oil during the first part of the test. These were removed. A new complete set of Bijurs were fitted during the test. The following Bijurs were fitted to increase the oil supply Rear dampers supplying the connecting links SO taken out SI fitted. Servo feeding cams SO taken out SI fitted Starter motor S.O.C. taken out S.O. fitted. Bijurs supplying cross steering tube ball ends restriction taken out. The oil pump leaks all down the dashboard on the inside when filled to full capacity. We find that this does not occur if the pump is filled to within one inch of the top. | ||
