E. 1,000 Hour Intervals
Figure 2–9. One-thousand-hour interval maintenance
schedule and checklist.
At 1,000 hour intervals, perform the following:
• Check boom chain tension (see 2.12.17).
• Check the fan belt (see 2.12.8).
• Change the transmission oil and filter (see 2.12.10).
• Change the hydraulic oil and filter (see 2.12.9).
• Change the transfer case oil (see 2.12.13).
• Change the axle oil (see 2.12.11).
• Change the wheel end oil (see 2.12.12).
F. 2,000 Hour Intervals
Figure 2–10. Two-thousand hour interval maintenance
schedule and checklist.
At 2,000 hour intervals, perform the following:
• Change the engine coolant (see 2.12.5).
2.12.2 Boom Wear Pad Maintenance
A. Boom Wear Pad Check
Daily, and every 10 hours of engine operation, visually
inspect the boom wear pads between the boom sections
at the rear and front of the boom for excessive wear
(Fig. 2–11).
The average expected service life of boom wear pads
varies depending on the particular location of each wear
pad within the boom, vehicle use, operating conditions,
and the load weight.
If load weights are at or near maximum capacity, or if the
vehicle is operating in very dirty or dusty conditions, the
boom wear pads will wear at a much faster rate.
Figure 2–11. Inspect boom wear pads for excessive wear.
The boom wear pads that are under the most stress from
weight of the load will also wear faster than other pads.
For example, the lower pads at the front of the boom are
under much more stress than the pads attached at the
top front or sides of the boom. Consequently, the lower
pads will require service more often.
B. Boom Wear Pad Replacement
Each boom wear pad is manufactured with a convenient
wear pad indicator. This is the angled cut at each end of
all boom wear pads (Fig. 2–11). The total thickness of a
new boom wear pad is 0.625 inch (15,9 mm). The angled
cut will provide a total wear thickness of 0.25 inch (6,4 mm).
This will leave approximately 0.375 inch (9,5 mm) of total
unused base material.
The pads must NEVER be worn past the angled cut indi-
cator, or the metal pad insert that holds the pads in place
will begin to wear into the boom pad sliding surfaces.
Pads worn past this point will gouge the boom surfaces,
resulting in premature wear of any new boom wear pads
installed, and requiring eventual, expensive replacement
of the boom. Replacement of boom wear pads must be
performed when the boom wear pads indicate.
C. Boom Wear Pad Lubrication
IMPORTANT: The boom has been factory lubricated for
proper wear pad break-in and will normally not require
further lubrication. However, after replacing any wear
pad(s), or after prolonged periods of inoperation, light
lubrication of the boom wear surfaces with a rust inhibitor/
lubricant such as
LPS 3
or equivalent is recommended to
keep the boom wear surfaces lubricated properly. Light
lubrication of the boom wear surfaces is also recommended
in salt air climates, and when the vehicle is stored, to help
prevent rusting.
LPS 3
