Wear Pads
How to Replace the Scissor Arm
Wear Pads
Platform Scissor Arm Wear Pads:
1 Remove the platform. See 2-1, How to Remove
the Platform.
2 Remove the wear pads from the slide blocks.
Discard the wear pads.
3 Using a mild solvent, clean the wear pad
mounting surfaces of both slide blocks.
4 Use a knife or scissors to cut the provided
double-sided adhesive tape to the correct
length.
Component damage hazard. Use
a knife or scissors to cut the tape
to length. Tearing the tape will at
the same time stretch the tape,
reducing the adhesive quality of
the tape. Do not tear the tape.
5 Remove the protective cover from the adhesive
tape and install the tape, equally spaced, onto
the slide block. Do not stretch the tape during
installation.
Component damage hazard.
Stretching the tape will reduce the
adhesive quality of the tape. Do
not stretch the tape.
6 Install the wear pads onto the slide blocks.
Securely fix the adhesive tape of the slide
blocks to the wear pads using firm, even hand
pressure.
7 Install the platform.
SCISSOR COMPONENTS
Chassis Scissor Arm Wear Pads:
1 Attach a lifting strap from an overhead crane to
the ladder at the non-steer end of the machine.
Support the ladder. Do not apply any lifting
pressure.
2 Remove the fasteners securing the ladder to
the chassis. Remove the ladder from the
machine.
Crushing hazard. The ladder could
fall if not properly supported when
the fasteners are removed from
the machine.
3 Secure both ends of the scissor arms together
with a strap or other suitable device.
4 Attach a strap from an overhead crane to the
non-steer end of the scissor arms.
5 Raise the scissor arms slightly at the non-steer
end with the overhead crane just enough to
take the pressure off of the non-steer end slide
blocks.
6 Remove the pin retaining fasteners from the
slide block pivot pin.
7 Place a rod through the pin and twist to remove
the pin.
8 Remove the slide block and remove the wear
pad mounting fasteners.
9 Install the new wear pad. Install and securely
tighten the fasteners. Do not over tighten.
10 Repeat steps 6 through 9 for the other wear pad
slide block.
11 Install the wear pad slide blocks into the drive
chassis and install the slide block pivot pins and
pin retaining fasteners. Securely tighten the
fasteners. Do not over tighten.
12 Securely install the ladder onto the machine. Do
not over tighten the fasteners.
