3.4.2 LUBRICATING OPERATIONS
(See Fig. 3.4/1)
The rotor head needs to be greased regularly, as per maintenance schedule diagram, to avoid an abnormal wear of
the teeter bearings pn NKXR 15Z, bolts pn NAS 628 ‐ 52 and pn NAS 628 ‐ 30, bushes pn 057 and pn 053 on which the
control movements are articulated and of the notched gear pn 061.
There are three lubrication points (pn 059 (short) and pn 286 (long)) on the rotor head.
During lubrication, the movement of the controls, or of the teeter axle, allows the head to be greased more easily.
First clean the notched gear pn 061, then lubricate it with humidity ‐ proof grease and apply a protective film on the
teeth.
If the forks pn 051 and pn 052, on the square block pn 056, are burnished (black colour), the same type of
lubrication must also be done on these items.
3.4.3 SUGGESTED TYPES OF LUBRICANT
Bearings and NAS bolts AMBER ‐ COLOURED GREASE SHELL DARINA R2
Notched gear and forks BLUE WATER ‐ REPELLENT GREASE
