APPENDIX B
Lubrication Instructions
Oil levels are to be checked with the LRT 110
Crane parked on a level surface in transport posi-
tion. Check while the oil is cold, unless other-
wise specified.
On plug-type check points, the oil levels are to
be at the bottom edge of the check port. Over-
lubrication of nonsealed fittings will not harm the
fittings or components. Under-lubrication will
lead to a shorter lifetime.
On sealed U-joints, care must be exercised to
prevent rupturing seals, Fill only until expansion
of the seals becomes visible.
Items not equipped with grease fittings, such as
linkages, pins, and levers, should be lubricated
with lubricating oil MIL-L-2104 once a week.
Oil, applied sparingly, will provide the necessary
lubrication and help prevent the formation of
rust. Grease fittings that are worn and will not
hold the grease gun, or those that have a stuck
check ball, must be replaced. Where slide pads
are used, cycle the boom and relubricate to insure
complete lubrication of the entire wear area.
All lubrication and check time intervals are based
on hours of operation under average working
conditions:

Daily or 8 hours, whichever comes first.
Weekly or 40 hours, whichever comes first.
Two weeks or 80 to 100 hours, whichever
comes first.
Three months or 250 hours, whichever comes
first.
l Four months or 500 hours, whichever comes
first.
l Six months or 1,000 hours, whichever comes
first.
l Yearly or 1,500 to 2,000 hours, whichever
comes first.
Time Intervals - Unusual Conditions
The LRT 110 Crane will require extra service
and care when operated under unusual condi-
tions. High or low temperatures, long periods of
hard use and continued use in sand, water, mud
or snow will break down the lubricants. Add or
change lubricants more often under these condi-
tions. However, during long periods when the
crane is not in use, the service intervals can be
lengthened.
Turntable Gear and Pinion Gear Teeth
Never apply grease to turntable
gear while the upperstructure is
in motion. Failure to follow this
procedure could cause DEATH
or serious injury.
Gear teeth must be lubricated with a saturated
brush or swab. Grease a segment; stand clear,
swing the upperstructure 10 degrees and grease
another segment. Repeat until entire ring gear is
coated.
