Huckerby}26.11.37. 1204 DISTRIBUTOR TESTS ON 26.G.VI. We fitted 26.G.VI with a Delco distributor cover positioned 3.500" above the exhaust manifold, to Rm{William Robotham - Chief Engineer}/Swdl{Len H. Swindell}'s instructions. The object being to ascertain under running conditions the difference in temperature of the cover in the above mentioned position, from that of the cover in the present Wraith position. Thermometers were attached and during a fast run temperatures taken. The one fitted over the exhaust reached a maximum reading of 70°C with the other at 60°C. Examination of the distributor cover after the test showed no damage from the heat. We would suggest, the test having been done on a cold day, the figures given should not be looked upon as approaching a maximum temperature under running conditions. We have taken the speedometer reading and will note any higher recording and also the condition of the cover during mileage. Sketch attached. Rm{William Robotham - Chief Engineer}/Brazier. | ||
