P. - 20. | 34. | Depot Sheet No. Hm.{Capt. W. Hallam - Head Repairs}105 has been issued showing the drilled valve in connection with the 20 HP. Chassis. This is also applicable to the 40/50 HP. Chassis. | | Piston knocks and Seizure. | W. 5. N. 6. P. 2. 13. | 9. | This is caused by insufficient oil for starting purposes, and leaving the starter carburetter working too long. An extra oil supply which operates when the engine is started up has been designed. It is advisable to get out a similar scheme for Phantom I from F2B series onwards. No progress has been made. | | Springing Complaints. | W. 40. N. 26. P. 10. 76. | 66. | We now fit oil holes and grooves to the spring plates, which in the case of the front springs are lubricated at the same time as the spring shackle. The front end of the rear spring is lubricated also from the spring pin lubricator. A special lubricator is fitted to the stop at the end of the main leaf. The general setting for shock absorbers is 100 lbs. up and down for front shock absorbers, and 80 lbs. up and 100 lbs. down for the rear shock absorbers. After this setting is obtained two .031" holes are drilled in each of the high pressure valve heads. | | ||
