REMOVE AND DISASSEMBLE
WARNING
Forklift truck frames and components may have
polyurethane paint. Welding, burning, or other heat
sufficient to cause thermal decomposition of the
paint may release isocyanates. These chemicals
are allergic sensitizers to the skin and respira-
tory tract; overexposure may occur without odor
warning. Should work be performed, utilize good
industrial hygiene practices, including removal
of all paint (prime and finish coats) to the metal
around the area to be welded, local ventilation,
and/or supplied-air respiratory protection.
There is very little repair required on the frame. See Fig-
ure 1. Most repairs can be done by removing the nec-
essary system parts. Refer to the section for the system
that must be removed. To separate the frame weldment
from the upright weldment, see the section Mast, Re-
pair 4000 YRM 764. To replace the load wheels in the
load arms, see the section Periodic Maintenance 8000
YRM 924 or Periodic Maintenance 8000 YRM 1472.
COVERS, PANELS, AND PLATES
The special plastic covers that protect the parts can be
removed by removing the screws that fasten them. See
Figure 1. There is one cover over the main frame weld-
ment. Two doors provide access to the electrical and
hydraulic compartments. The panels at each end of
the battery compartment can be removed by lifting them
straight up and out of the slots in the frame.
CASTER AND CASTER WHEELS
Description
The caster is one support for the front of the lift truck
and is under the hydraulic compartment. See Figure 2.
The drive wheel of the master drive unit is the other sup-
port for this end of the lift truck. The axle of the caster
is an articulated axle. The articulated axle permits both
wheels of the caster to always have equal weight. This
allows for better operation and wear. The caster is fas-
tened to the frame weldment by four capscrews and
lockwashers. The complete caster can be replaced as a
unit, or the wheels can be replaced. Always replace the
wheels as a set for better caster operation and wheel
wear. A single new wheel of the set will wear rapidly.
