Reach Assembly Removal and Installation
Reach Assembly Removal and Installation
1.
Operate the LIFT/LOWER controls to raise the
reach assembly until the rollers of the rear frame
(reach) are above the top of the outer weldment.
2.
Operate the REACH/RETRACT controls to fully
retract the forks. Install safety chains so the
forks cannot extend. Install the safety chains
around the center plates of the scissor arm weld-
ment and the reach frame. Make sure a safety
chain does not touch the mount for the hose
sheave, lift chains, chain or hose sheaves, hoses,
tubes, or fittings.
3.
Move the key to the OFF position and disconnect
the battery. Remove the mast guard from the
mast assembly.
4.
Use safety chains to fasten the movable member
of the mast to the outer weldment so it cannot
move.
WARNING
Be careful when removing or installing snap
rings.
These snap rings are large and can
come loose during removal or installation with
enough force to cause an injury. Always use
the correct snap ring pliers, and wear eye and
face protection during removal or installation.
5.
Remove the snap rings, washers, thrust rollers,
and spacers.
6.
Disconnect the hydraulic lines (sideshift or reach
only) at the inner frame. Put tags on the fit-
tings for correct connection during installation.
Make sure to put caps on the open fittings to keep
dirt out of the system. Disconnect the electrical
connections (reach only) at the base of the inner
frame.
NOTE:
Removing the pins at the chain anchors
will disconnect the lift chains without changing the
chain adjustment. Always adjust the chains if new
lift chains or other components are installed.
7.
Hold the lift chains to keep them from falling.
Remove the pins in the chain anchors at the back
of the outer weldment of two-stage masts. Re-
move the pins in the chain anchors at the back
of the free-lift cylinder of three-stage masts.
Disconnect the lift chains. Carefully move the
lift chains through the sheaves and lay the lift
chains over the reach assembly.
WARNING
The inner frame assembly is heavy and can
cause an injury if it tips or falls. Make sure
the carriage assembly has stability during and
after removal. If the forks are removed, put
the carriage assembly on the floor so the load
rollers are up.
CAUTION
DO NOT damage lift chains, hoses, or electrical
cables as the carriage assembly is lifted out of
the mast weldment.
8.
Carefully lift the reach assembly out of the chan-
nels of the rear weldment. Carefully lower the
reach assembly to the floor.
NOTE:
The reach assembly side rollers must be ad-
justed while the reach assembly is out of the mast.
Adjust the side rollers as described in Carriage or
Reach Assembly Adjustments, Adjust Side Rollers
before installing the reach assembly.
9.
To install the reach assembly, reverse the re-
moval procedures.
Always use new chain an-
chors when installing the lift chains.
Apply
Loctite™ to the studs of the thrust rollers during
installation.
10. Adjust the reach assembly. See Adjust Reach
Cylinders, Carriage or Reach Assembly Adjust-
ments. Test the reach assembly for correct oper-
ation.
