1.3 Maintenance
This section will describe the general maintenance of the system. Since the OMS consists of several parts
that rotates, lubrication plays a big role. Inspection of fixture points in regards of deformation is also
brought up in this section.
Lubrication of Slew Bearing
Lubrication of the slew bearing shall be done as specified by SKF in their catalogue [3] using LGEP 2 [2]
or an equivalent oil.
Lubrication of Pinion
To get access to the pinion the offset disc must be removed first, then the power-train disc can then be
unbolted from the bearing.
The pinion interface must be regreased every 12th week. Before regreasing the gear, the teeth should be
cleaned of any impurities. The lubricant can be brushed or sprayed onto the gear or by any other suitable
method. The grease applied must have a base oil viscosity of at least 500 mm 2 /s at 40°C, have good
adhesive properties and a high resistance to water washout [3].
Lubrication of Bolts
All off the fixtures in the assembly comes in the form of bolts. Like described in safety under assembly
1.1, the bolts may get stuck together as a result of corrosion. An appropriate countermeasure is lubrication.
PERMATEX® #133 Anti-Seize lubricant [1] is suggested. This lubricant is applied to all bolt fixtures in
the assembly, and is important in order to ensure easy assembly, and disassemble.
Inspection of Fixture Points
The most critical points of the product is the fixture points. Whenever the OMS is assembled or
disassembled an inspection is performed on all fixture points. The inspection will involve detecting
hazardous deformation in the material. This will prevent any unforeseen deformation in the member.
This inspection is performed at any assembly or disassemble.
