Appendix 4: RECOMMENDED GREASES AND OILS AND TIGHTENING
TORQUES OF THE SCREWS
1. The grease used for lubricating the bearings of the propulsion unit must meet
the requirements below.
- lithium soap and a thickener with EP additives
- mineral oil as a base oil
- NLGI class 2
- operating temperature range –25…130˚C
- continuous operating temperature min. 75˚C
The following grease brands are recommended as an example:
Würth Multi-Purpose Grease III, FAG Multi2, FAG Load 220, Mobil XHP 222,
Neste Allrex EP2, Shell Retinax Grease EP2.
A grease that has equivalent properties to those mentioned above can also be
used for lubricating.
2. The operating hydraulic system of the reversing deflector has been designed
operate with automatic transmission oil.

3. The tightening torques in the table below must be used when tightening
the screws on the propulsion unit. The values 8.8, 10.9, and 12.9 signify the
strength classes of the screws. The strength class of the A4-80 acid-proof screw
corresponds to a 8.8 class screw.
