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
sections 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.
