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
lubricating with “LPS-3” (or equivalent) of the boom wear
surfaces is recommended to keep the wear pads and
boom wear surfaces lubricated properly. Light lubricating
of the boom wear surfaces is also recommended in salt
air climates or when vehicle is to be put in storage to
prevent rusting. than other pads. For example the lower pads at the front of
the boom are under far more stress than the pads attached
to the top, rear or sides of the boom. Consequently the
lower pads will require service more often.
E. Wear Pad Replacement
(As Wear Pad Indicators Indicate)
Each boom pad is manufactured with a convenient wear
pad indicator. This is the angled cut at each end of all
wear pads (Figure 61). The total thickness of a new wear
pad is .625" (15,9 mm). The angled cut will provide a total
wear thickness of .25" (6,4 mm). This will leave approxi-
mately .375" (9,5 mm) of total unused material.
The pads must never be worn past the angled cut indica-
tor because the metal pad insert that holds the pads in
place will begin to wear into the boom pad sliding sur-
faces. If pads are worn past this point it will cause
gouging on boom plate surfaces. This will result in
premature wear of any new wear pads installed if the
surfaces are not ground smooth again.
Replacement of boom wear pads must be performed by
an authorized JLG distributor when the wear pads indicate.
