| -5- PHANTOM III. (1) Swdl.{Len H. Swindell}) Will investigate silent tappets sticking when starting up from cold. Wym.{G. Harold Whyman - Experimental Manager} ) Extra oil to tappets due to filter alterations causing top overoiling. (2) Dodd. Why does 33-EX detonate worse than 32-EX. Check over. (3) Std. How soon can we get a quiet thermometer for 33-EX. (4) F.J.H. 33-EX steering bad and clanks over a bad road (column noise). Experiment with side steering tubes. 36-EX also bad. Have we lower steering ratio on all cars. 33-EX & 36-EX have latest s.s. tube springs. Report. (5) Dodd. Ph.III relief valves noisy starting up? Swdl.{Len H. Swindell} Cure required. (6) Les.{Ivan A. Leslie} Front suspension on 32-EX & 33-EX clanks over bad roads at slow speeds (King's Drive). This should be investigated. Keep On. (7) Dodd. Co-operate with Mx.{John H Maddocks - Chief Proving Officer} to determine how to overcome SpectreCodename for Phantom III overoiling. (8) Swdl.{Len H. Swindell} Let me have power curves comparing unit in 33-EX with a standard Ph.III hydraulic tappet job. (9) Std. Carry out water spilling tests on 33-EX, if necessary completing tests by forcing more water to go round the back of the heads. | ||
