FLEXIBLE FLYWHEEL, WRAITH OR BENTLEY. Please prepare another flexible flywheel to the following drawings herewith. Rm. {William Robotham - Chief Engineer} 233 Arrg. Rm. {William Robotham - Chief Engineer} 334 Flywheel 1 off D {John DeLooze - Company Secretary} /W not heat treat. Rm. {William Robotham - Chief Engineer} 335 Inertia ring 1 off C/W not heat treat.

Rm. {William Robotham - Chief Engineer} 229 Bolt 8 " " Rm. {William Robotham - Chief Engineer} 229 8 " " Rm. {William Robotham - Chief Engineer} 503HousingIsd. Spigot bearing 1 " D {John DeLooze - Company Secretary} /W not heat treat. EX.30668 Bolt, coupling 12 off D {John DeLooze - Company Secretary} /W heat treat. (suggest make 3 sets of these bolts) This wheel is generally similar to the previous one Rm. {William Robotham - Chief Engineer} 498 but with the following modifications. (1) Disc is thinner to provide increased flexibility. (2) The inertia ring is reduced so that the crankshaft can be removed without removing flywheel. (3) It is drilled for either 10" or 11" B. & B. clutch. These parts enable us to try wheels of four different inertias. Rm {William Robotham - Chief Engineer} /WRC, | ||
