| -3- Rm{William Robotham - Chief Engineer}/CWH.26/M.6.4.38 Cont'd.{John DeLooze - Company Secretary} Steering. (1) Low speed wobbles, due to front wheels being out of balance, and drop of frictional load on cross steering tube. 6. (2) Joggles - Side steering tube frictional load dropped. 4. (3) Knocks from side steering tube rear end. 4. (4) Knocks and slackness in needle bearings of bottom yoke ( lack of lubrication). 2. (5) Steering not directional due to side play in roller of rocker shaft and needle bearings chipped and inner race damaged. 2. Total 18. Clutch. (1) Shuddering, changed for Long Plate with Thermoid linings. 9. (2) Long Plate Thermoid lining grabs after short mileage. 4. (3) Long plate shuddering due to worn stud of stay on gearbox. 1. (4) Slight binding of clutch splines ( slow stopping). 1. (5) Clutch thrust race noisy due to lack of lubrication. 3. Total. 18. Recurrent failure of Long Plate Clutch with Thermoid lining has been dealt with, and cures will be obtained by reducing the strength of clutch springs ( memo reference Hm.{Capt. W. Hallam - Head Repairs}11/M.23.3.38. Clutch thrust race has been dealt with by Mod. S.CD.496. Continued.... | ||
