6.5 Lubrication
6.5.1 General Remarks
Lubricants:
For friction bearings steel-on-steel and roller bearings use lubricants and oils based on MoS
2
. For bearings
containing brass, bronze or copper components, only MoS
2
-free lubricants and oils shall be used.
Engine:
For lubrication of the engine, the instructions according to the "Maintenance Manual (Line Maintenance) for
ROTAX Engine Type 914 Series”, section 12
-00, (Annex E) have to be observed.
Bearings of Control System and Control Surfaces:
The control system bearings in the fuselage and in the wings are provided with permanent greasing and do
not require any service for a long period.
The control surface bearings (except rudder bearings) are coated and normally greasing is not required.
However, greasing may be necessary in aggressive environmental conditions when bolts show first signs of
corrosion. In this case use MoS
2
-free grease.
The rudder hinges must be greased depending on the degree of exposure to contamination (specially the
lower hinge).
Connection of the Propeller Extension Shaft to the Clutch on the Engine side (splined joint):
Shafts without hard film coating
(Glaencer Spicer, MAN in some cases):
(MoS
2
-free) lubrication during special inspection.
Shafts with hard film coating:
Commercially available Teflon spray or non-acid
grease can be used for lubrication if there is only
minor damage to the hard film coating.
Caution:
Typical identification for drive shafts without hard film coating is the blank metall surface on
the splined joint.
Canopy Locking:
Always keep well-greased. Use MoS
2
-free lubricant, since the rod bearing within the canopy frame is made of
brass.
