The tolerances of the battery compartment are +3 and 0 mm (+0.12 and 0 in.). The battery size column
shows the size range that will permit the battery to still fit into a battery compartment.
The battery compartment length is front to back. Width is side to side. The length dimension of the battery
must fit within the battery compartment side-to-side dimension with a clearance of 0 to 13 mm (0 to 0.5 in.)
maximum. Battery width must fit within the battery compartment front-to-back dimension.
WARNING
The battery must fit the battery compartment so that the battery restraint system will operate
correctly. Use only batteries with the correct length shown in this table. Adjust the spacer plate
and side spacers to prevent the battery from moving more than 13 mm (0.5 in.) either direction.

6. 1600 SRM 720 Description
General
This section has the description and repair procedures for the steering housing and the steering control unit.
Additional information on parts of the steering system can be found in the Steering Axle and Hydraulic
System service manual sections for your lift truck.
Description
The steering column assembly uses a steering con-
trol unit with hose connections on the bottom of the
unit. The steering housing has mounts for the steer-
ing column and the steering control unit. The steer-
ing wheel is installed on the steering column. See
Figure 1. The housing is adjustable and is held in po-
sition by a latch. The position of the housing can be
changed for operator comfort. The steering housing
is also the mount for control levers and some instru-
ment clusters.
The steering system is a hydraulic system that does
not have a mechanical connection between the steer-
ing wheel and the steering axle. The control of the
steering is through a hydraulic circuit.
If the hydraulic pump for the steering system does
not operate, steering is still possible. A check valve
permits the steering control unit to control the steer-
ing cylinder. The lift truck is difficult to steer when
the steering pump is not operating, but the steer-
ing control unit can operate the steering cylinder and
make steering possible.

7. Operation 1600 SRM 720
Operation
The steering control unit is a rotary valve operated by
the steering wheel. See Figure 2. During the steer-
ing operation, the steering control unit controls the
direction and amount of oil flow to the steering cylin-
der. The steering cylinder in the axle actuates the
steering linkage to move the steer tires. Hydraulic
oil returns from the steering cylinder to the steering
control unit and then to the hydraulic tank.
Turning the steering wheel actuates three main
parts of the steering control unit: the spool for the
control section, the sleeve for the control section, and
the rotor in the metering section. When the steering
wheel is not moving, the spool and sleeve are held
in the NEUTRAL (center) position by springs. Dur-
ing this time, oil flows freely through the steering
control unit but none flows to the steering cylinder.
As the steering wheel is turned, the spool just be-
gins to rotate. The springs try to move the sleeve to
keep the NEUTRAL position between the spool and
sleeve. However, the necessary force to turn the ro-
tor is greater than the pressure of the springs. The
springs begin to bend, letting the spool move a small
amount within the sleeve. The spool stops moving
when it touches the center pin. In this position, the
holes in the sleeve and the spool are aligned. Oil com-
ing into the control unit flows to the metering section.
More rotation of the steering wheel causes the spool
to rotate the pin. This action causes the rotation of
the sleeve and the rotor in the metering section. The
oil then flows to one side of the steering cylinder. Oil
from the other side of the cylinder returns through
the control section of the steering control unit.
When the steering wheel stops moving, the meter-
ing action in the metering section also stops. The
NEUTRAL position springs return the sleeve to the
NEUTRAL position, stopping oil flow to or from the
cylinder. The pressure stays in the steering cylinder
to keep the steer tires in position. Oil from the pump
flows through the steering control unit to the tank or
other parts of the system. To return the steer wheels
to the straight position, the steering wheel must be
rotated in the opposite direction. The steering con-
trol unit will operate as described, but all parts will
rotate in the opposite direction.

Steering Wheel and Column Assembly Repair
The upper end of the steering shaft has splines for the
steering wheel. A large hex nut holds the steering
wheel onto the steering column. The horn button is
the cover for the center of the steering wheel. The
lower end of the steering column has splines or a tang
to engage the steering control unit. See Figure 5 and
Figure 6.
The steering column assembly is adjustable and held
in position by a latch. The position of the steering col-
umn assembly can be changed as needed for different
operator requirements. An access cover on the steer-
ing column gives access to the steering control unit,
key switch, horn switch, and if installed, the direc-
tion switch.
ASSEMBLY COMPONENTS, REMOVE
NOTE: This procedure is for the removal of all com-
ponents of the steering column assembly. All compo-
nents are not often removed for a repair procedure.
Do only those steps of the procedure necessary to re-
move the required component. See Figure 5 and Fig-
ure 6.
WARNING
The hydraulic hoses must be connected to the
correct ports or the steering system will not op-
erate as expected, which can cause damage or
personal injury. Make sure the hoses are iden-
tified and connected correctly.
CAUTION
Disconnect the negative battery cable on inter-
nal combustion trucks. Disconnect the battery
connector on electric trucks. Disconnect the
battery before removing any covers.
1. Attach a tag on the battery connector or negative
cable stating DO NOT CONNECT BATTERY.
Move the steering column to the most FOR-
WARD position. Remove the column tilt lever.
Remove the upper and lower access covers from
the steering column.
2. Remove the key switch and static strap from the
housing of the steering column. Make an identi-
fication of the electric wires and disconnect them
from the key switch.
3. On units with the Direction Control Handle,
Remove the direction switch assembly from the
housing of the steering column. Make an identi-
fication of the electric wires and disconnect them
from the direction switch. See Figure 3.

CAUTION
If a puller tool is used to remove steering wheel
from steering column, be careful not to damage
the horn wires.
5. Remove the horn button assembly and electrical
wires. Remove the large hex nut and the steer-
ing wheel from the shaft. A puller tool makes
removal of the steering wheel easier, but not all
steering wheels have puller holes.
6. On lift truck models J2.00-3.20XM (J40-

(C210), and E2.00-3.20XM (E45-65XM2) (F108)
units, remove the optical encoder housing and
optical encoder from the steering column. Make
an identification of the electrical wires and dis-
connect them from the assemblies. See Figure 5.
7. On lift truck models J2.00-3.20XM [J40-
65Z] (A416/B416), E1.50-2.00XM [E25-35Z,

(G108), disconnect the connector. Remove the
two capscrews and steering sensor from the
steering column. See Figure 6.
8. Make an identification of the hydraulic hoses
at the steering control unit so they can be con-
nected correctly during assembly. See Figure 4,
Figure 5, Figure 6, and the WARNING in the
beginning of this section. Some hydraulic hoses
have fittings that will permit disconnection at
the steering control unit. Disconnect the other
hydraulic hoses at the base of the cowl, the
control valve, or the steering pump. Remove
all mount clamps so that the hoses will turn
freely and not become twisted. Disconnect the
hydraulic hoses at the bottom of the steering
control unit. Install plugs at all hoses and ports
to prevent dirt from entering the steering hy-
draulic system.

WARNING
Cleaning solvents can be flammable and toxic
and can cause skin irritation. When using
cleaning solvents, always follow the solvent
manufacturer’s recommended safety precau-
tions.
WARNING
Compressed air can move particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel. Wear protective
goggles or a face shield to prevent injury to the
eyes.
Clean all the parts in solvent. Dry the parts with
compressed air. Do not dry the parts with a cloth.
Make sure all surfaces are free of scratches and sharp
edges.
