SECTION 5 - MAST COMPONENTS
5-12 – JLG Lift – 3121187
c. Check mast section for side play. If play exists
add .015" shims dividing the thickness equally
between both sides of mast. Insert shims until
the shims cannot be inserted halfway by hand
with the mast pulled to the opposite side.
d. When mast slide pads are shimmed properly,
there should be no side to side movement of
slide pad in rail channel. Mast sections should
be snug in channels but still be able to slide in
channel by hand.
8. Insert slide pads into the slide pad channels (top of
mast) between section-1 and -2, (one on each side
of the mast), with beveled surface facing in towards
section-2.
NOTE: Before fastening and shimming the slide pad on the
top left side of the mast, install a sequence cable
bracket against the mast under the flatwasher.
9. Thread slide pad attaching bolts, two (2) 1/4"-
20UNC x 3/8" long hex head bolts, place a flat
washer under head of each bolt, through holes in
mast section-1 outside rail (top of mast) and into the
slide pad inserts. Thread in enough to hold pad in
place.
10. Shim per instructions in step 7, Mast Section 2 -
Assembly.
11. Before installing the lift cylinder to mast section 1
and into mast section-2, extend the lift cylinder rod
out the top of the lift cylinder approximately 1 ft.
(31cm).
NOTE: To extend the hydaulic cylinder the protective caps
on the extend and return ports will need to be tempo-
rarily removed. Be careful not to nick or scour rod
surface when extending, also catch any oil draining
out of cylinder to avoid spillage onto work area.
12. Install the lift cylinder mount into the bottom of Mast
Section 1 and the cylinder into Section 2.
13. At the bottom of mast section-1 check for side to
side clearance of the cylinder mount. Use mounting
shims of equal thickness on each side to center the
mount in the closed rail portion, as necessary.
14. Install the mount reinforcement plates and mount
bolt and washers. Apply Loctite #242 to threads of
mounting bolts before final assembly.
