5-2 Weekly Maintenance and Lubrication (See lubrication diagram DET-049)
The following section identifies areas of the equipment that need to be checked on a weekly basis.
5-2A Roll Ring Sub-Assembly
Inspect the condition of the roll ring sub-assembly. Verify that the slip rings are free to rotate and free of
external contaminates that may enter the rings.
5-2B Pitch Ring Sub-Assembly
Inspect the condition of both pitch ring assemblies. Verify that the slip rings are free of external
contaminates that may interfere with data transmission. Verify the cable support system is secured to the
A-Frame cabinetry
5-2C Pitch Shaft Assemblies
Lubricate the pitch arm bearings with multi-purpose wheel bearing grease. Inspect the mount root
area for possible fatigue or cracks using the non-destructive test method. See DET-050.
5-2D Key Way Sub-Assemblies
Inspect the keyways for damage and tightness of the bolts. Lubricate the guides with a lithium grease
lubricant.
5-2E Counterweight Sub-Assembly
Inspect the counterweight system, checking for any condition that would interfere with the proper operation
of the counterweight system. Clean and lubricate the counterweight shaft at this time. Inspect the retaining
bolt safety wires and the bolts for tightness. Lubricate with white lithium grease.
5-2F Counterweight Worm Gear
Lubricate the counterweight worm gear with lithium grease once a month to insure proper operation of the
counterweight system.
5-2G Electrical System Sub-Assemblies
Verify that all of the electrical connections are tight. Verify that each of the sensor switches (5) are
operating correctly.
