Gearboxes
1. Gearboxes
Replace oil in gearboxes after the first 50 hours of operation then yearly.
Check gearbox oil level frequently. Steady loss of oil will indicate damaged seals, which should be
replaced immediately to prevent ruining the gearbox.
Procedure for refilling of gearboxes:
-A dip stick is provided on the vent plug. Fill until oil shows on the dipstick. Do not screw
dipstick in when checking oil level.
-Use of an oil/grease pump to suck oil out of the gearbox is recommended to minimize
spilled oil and to provide for more complete removal of old oil.
2. Gear case oil should meet the following specifications:
-API Service Classifications GL-5
-Military Specification MIL-L-2105C
