The gears have a 12 helix that not only gives rise to quiet running, but also increases in strength. At the higher power levels an oil cooler will have to be used, which can be plumbed into the existing oil system. The lubrication system delivers oil to all bearings as well as the pressure faces of the gears, each outlet is orificed to provide the correct flow to each position. The flywheel drive mechanism is of the damped variety to provide sufficient drive but eliminates as much of the harmonics of the propeller and gearbox passing to the engine as possible. The propeller mounting flange is a standard SAE No. 2 with the main shaft being hollow to allow for the passage of oil for altering the propeller pitch.
All bearings are standard sizes but carry compliance from the manufacturers for aircraft use.
The seals are also standard sizes but these carry no use by conditions. The lubricating oil is a Castrol automatic transmission Dexron 3 which is available world wide. The main case carries two side mounting flanges drilled and tapped to suit various applications. The idler shafts are also tapped and doweled to accommodate any oil pump of C.S.U. drive that needs to be utilized. Overall the gearbox is of a robust design that has a calculated life in excess of 26,000 hours of operation.
