STEERING SYSTEMS FOR ELECTRIC LIFT TRUCKS
GENERAL
There are two different steering systems available: Pow-
er Steering and Power Steering with On–Demand. The
difference in the components for each system can be
found in FIGURE 1. Also see FIGURE 2. This section
covers the description, disassembly, assembly, checks
and adjustments and the troubleshooting of the steering
system. There is a description for each part of the steer-
ing system at the beginning of each repair section. On
units with three wheels, the steering system turns the
Master Drive Unit (MDU) to steer the lift truck. On units
that have four wheels and a steering axle, the steering
system operates the steering cylinder to steer the lift
truck.
Additional information for the components of the steer-
ing system is found in the following sections:
MASTER DRIVE UNIT, 630 SRM 363, contains the
description and repair of
the MDU for
the
A1.00–1.5.XL (A20–30XL).
THE STEERING AXLE, 1600 SRM XXX. The SRM
number is different for different models. See the Table
Of Contents of the Service Manual for your unit to see
the correct description and repair procedures for the
steering axle.
THE STEERING CONTROL UNIT, 1600 SRM
XXX. The SRM number is different for different mod-
els. See the Table Of Contents of the Service Manual for
your unit to see the correct description and repair proce-
dures for the steering control unit.
A modification has been made in the manifold assembly
of the steering control unit used in the A1.00–1.50XL
(A20–30XL) trucks that is different than the unit de-
scribed in THE STEERING CONTROL UNIT, 1600
SRM 54. The four hydraulic ports are in the bottom of
the steering control unit. These ports connect to the four
hydraulic hoses for the steering system. The four hy-
draulic ports on the side of the steering control unit are
not used.
