3. If the power-trak assembly was left attached to the
the mast assembly, to remove it now, remove the
two (2) screws attaching the power-trak guide to the
mounting lug at the top of the mast. Slide the hanger
bracket out of the slot in the front of the mast sec-
tion. Now slide the complete power-trak assembly
with cables out of the top of the mast assembly.
4. To remove the mast sections from each other, slide
the mast sections apart until the rivets attaching the
slide pads to the bottom corners of the mast sec-
tions are exposed. Remove the rivets from the slide
pads on the mast sections you want to remove at
the bottom of the outer-mid and inner-mid mast sec-
tions, then slide the mast section out the bottom.
Mast - Reassembly
(Refer to the Mast Disassembly illustrations when required)
1. If required, assemble the external slide pads to the
top of the outer-mid, inner-mid and mount/inner
mast section. Orient the groove in the pads to the
side of the mast and attach with the proper rivets
from the inside of the mast. (See Figure 6-3.)
NOTE: Always mount slide pads with the groove oriented to
the side of the mast not the front or rear, for clear-
ance of the pad mounting rivets during opera-
tion.(See Figure 6-3.)
The slide pads are available in two thicknesses:
JLG P/N-1001092165 - (9,7 mm thick) - round notch
on ends
JLG P/N - 4700042 - (8,7 mm thick) - NO round
notch on end
Always use the 1001092165 slide pad unless mast
tube clearances prevent installation.
2. Slide the inner-mid and the mount/inner mast sec-
tions into the outer-mid mast section. Allow the
mounting holes for the bottom slide pads of the
inner-mid mast section to be exposed. (See Figure
6-14.)
3. Push the bottom slide pads into the bottom of the
outer-mid and the inner-mid mast sections, mount
with the groove in the pad towards the side of the
mast. Attach with the proper rivets. (See Figure 6-
14.)
