GRADE OF PETROL: Esso Ethyl. GEARBOX LUBRICANT: Motorine C. STARTER TEST DATE AND TIME: 8.7.35. 10.35 a.m GRADE OF OIL: Castrol XL TEMPERATURE °C.: OIL: - AIR: -1.4 BATTERY: -1.4 CLUTCH: IN STARTER: AMPS.: 212-200 VOLTS.: 7.4-7.2 BATTERY: VOLTS.: 8.8-8.6 SP.{Mr Spinney} GR.{George Ratcliffe}: 1.280 R.P.M.: STARTER: 1190 ENGINE: 70 *TORQUE: STARTER: 5.75 lbs. ft. ENGINE: 97.8 lbs. ft. CLUTCH: ---- Repeat test CLUTCH: IN STARTER: AMPS.: 208-192 VOLTS.: 7.35-7.15 BATTERY: VOLTS.: 8.7-8.65 SP.{Mr Spinney} GR.{George Ratcliffe}: 1.280 R.P.M.: STARTER: 1190 ENGINE: 70 REMARKS: The torque is correct by current and speed curve but is low when deduced from volt curve. There is rather an excessive volt drop in cable. *TORQUE DEDUCED FROM CALIBRATION CURVE No. | ||
