Draining and Inspecting Gear Lubricant
WARNING

from spark plugs before working near the propeller.

remove vent plug and fill/drain plug (with gaskets).

Vent Plug/Washer

Drain Plug/Washer
2.
Inspect gear lubricant for metal particles (lubricant will have a “metal flake”appearance).
Presence of fine metal particles (resembling powder) on the drain plug magnet indicates
normal wear. Metal chips on the magnet indicate the need for gear housing disassembly
and component inspection.
3.
Note color of gear lubricant. White or cream color indicates presence of water.
4.
Presence of water indicates the need for disassembly and inspection of oil seals, O-
rings, gaskets and components for damage. Pressure check prior to disassembly to
determine leak area.
