INSPECTION & SERVICING
11 LUBRICATION
11.1 INTRODUCTION
Periodic lubrication of moving parts insures proper operation and ex-
tends parts’ life considerably.
Lubrication type, points and intervals are indicated below.
Avoid excessive lubrication as this may cause external surfaces of
hinges and bearing to collect dirt and dust.
If part is not lubricated using a grease gun, grease part by hand re-
moving excess.
To grease main gear wheel bearings, first remove thrust bearings
from wheel hubs, then clean surface using solvent, apply grease and re-
assemble.
NOTE - Use grease type MIL-G-3278 or equivalent (e.g. ESSO
BEACON 325).
