6.11) Lubrication of wire rope
6.12) Using fresh water wash
Fill the rotating tub ¾ of the way with fresh water and extend the wire rope all the way down.
Using a hose, rinse off the helicopter hoist and the wire rope between the helicopter hoist and the
rotatub. If shop air is available, attach an air line to the lubridryer via the quick disconnect nipple
supplied with the RHGSE.
(See section 6.13)
Run the hoist in the up direction with the load brake
applied. Before operating with water rotate the load adjuster counter clock wise to reduce the load to
approximately 100 lbs.
Carefully observe the wire rope at all times on the capstans. Retract the entire wire rope out of the
rotatub, and position the drum so that the pug is above the hole in the frame then remove the plug at
the bottom and drain into an approved drain.
If shop air is unavailable and the onboard compressor is not installed, remove the water and
dry out the Rotatub extend the cable into the empty tub and let dry. Retract the wire rope onto the
helicopter hoist with the load lever applied using a gloved hand and a clean cloth to dry the wire rope.
The Lubridryer includes a reservoir
that can be filled with oil. Use oil only as per
the hoist manufacturer’s recommendations.
The reservoir can be used to store spare
Lubridryer pads. The Lubridryer includes a
valve that shuts off the flow of oil when not in
use
When oil is added to the reservoir and
the valve is open the oil seeps through a
small hole to lubricate the rear pad. The front
pad should be soaked in oil before installing it,
open the oil reservoir and dip the pads into
the oil filled reservoir. Therefore, it is
recommended to always keep a spare set of
pads in the reservoir of oil to use as the next
set.
Wipe excess oil off of the frame and
use a clean cloth to keep the oil off of the
capstans when the RHGSE is not in use.
