any protective caps and clean off each lubrication fitting prior to injecting fresh grease.
The elevation and azimuth jackscrew assemblies are equipped with a grease fitting and
corresponding pipe plug on opposite sides of the jack housing. Remove the appropriate
pipe plug and fill with with grease until lubricant seeps from the pipe plug opening.
Replace and securely tighten pipe plug.
The following is a list of the lubricant characteristics:
•
Mobil Temp SHC32

ture range is -65 degrees to 350+ degrees Fahrenheit (-54
degrees to 177+ degrees Celsius).
•
Mobil SHC624
A low temperature synthetic oil for worm gear reducers.
Operating temperature range is -40 degrees to 125+ degrees
Fahrenheit (-40 degrees to 52+ degrees Celsius).
•
Moly Grease
A grease lubricant containing molybdenum disulfide. Operating
temperature range is -85 degrees to 300+ degrees Fahrenheit
(-29 degrees to 149+ degrees Celsius).

* Inspection requires checking for visible signs of oil leakage, draining replacing and adding oil to ensure appropriate oil
level requirements. Excessively dirty oil will require fresh oil replacement. If oil leakage is found to be excessive, refer to
appropriate troubleshooting information and perform applicable corrective action. Periodic inspection procedures can be
less frequent after first or second scheduled inspections.
** Initial oil change requirements include flushing gear boxes with a standard cleaning agent.
