General
This section has the description and repair procedures
for the frame and connected parts. Included in this sec-
tion are the frame, counterweight, fenders, hood, hy-
draulic and fuel tanks, radiator/cooling section, opera-
tor compartment, and cab. The instructions for removal
and installation of the engine are included in this sec-
tion.
If the lift truck is fitted with a battery disconnect switch,
open the switch if welding on the engine and remove
the ECM (Engine Control Module). If welding on the
lift truck chassis, verify the ground clamp is placed as
close to the welding point as possible and NOT near the
ECM. If it is necessary to weld near the ECM, remove
the ECM from the engine to avoid damage from welding
arc radiation.
Description
The frame is a one-piece weldment and has mounts
for the counterweight, fenders, engine, transmission,
axles, hydraulic and fuel tanks, operator’s compart-
ment, and other parts. See Figure 1.
