Operation

General

This section has a description and the repair procedure for the main control valve and the auxiliary solenoid
valve used in the hydraulic system.

Description

The main control valve controls the operation of the
lift, tilt, and auxiliary cylinders. The main control
valve is fastened to the cowl of the lift truck. Each
main control valve has the following sections (see
Figure 1):
• Inlet and drain section with the primary relief

valve

• Lift and lower section (with or without secondary

relief valve)

• Tilt section
• Auxiliary section
• End section

The sections are held together with three through
bolts.

Each function of the main control valve is made as a
separate section having a spool and valve body. Each
valve body casting is the same. The control spools
are different for each function.

Other sections are added to the main control valve
to control optional auxiliary functions. On some lift
trucks, a solenoid valve is used with one of these sec-
tions to give another auxiliary function.

Each spool has a spring that returns the spool to the
neutral position when the control lever is released.
Each control section has a check valve in the valve
body. The check valve and spring is held in the valve
body by the next section.

Operation

The main control valve is an open center, parallel cir-
cuit valve. See Figure 2. When open center valve
spools are in the neutral position, the hydraulic oil
flows through the valve with minimum restriction.
The oil returns through the drain passage and re-
turns to the hydraulic tank.

In a parallel circuit

valve, each spool can be operated without prevent-
ing the flow of oil to another spool.

This valve has three parallel passages through the
valve. See Figure 3. When the spools are in the
neutral position, the oil flows through the open cen-
ter passage. At the end of the valve, the oil returns
through the drain passage and returns to the hy-
draulic tank. A spool makes a restriction in the open
center passage when the spool is moved from the neu-
tral position. This restriction causes an increase in
pressure in the parallel passage. The parallel pas-
sage is common to all sections of the valve, but oil

cannot flow freely through it. The increased pressure
in the parallel passage causes the oil to flow through
a check valve into a supply cavity in the valve body.
The spool gives a path from the supply cavity to the
hydraulic cylinder to do work.

LIFT SECTION

When the spool is moved to the Lift position, the spool
makes a restriction in the open center passage. See
Figure 3. The increased pressure in the parallel pas-
sage causes oil to flow through the check valve to the
supply cavity. The oil flows from the supply cavity
through a section of the spool to the lift cylinder.

When the spool is in the Lower position, the spool
opens a path from the lift cylinder to the drain cavity.
The spool is made so the oil flow through the open
center passage is not stopped.

Operation

TILT SECTION

The basic operation of the tilt spool is the same as
the other spools in this control valve. The tilt control
spool that is inside the tilt spool adds an additional
sequence to the tilt forward function.

Tilt Backward

When the spool is moved to the Back tilt position, the
tilt spool causes a restriction of the oil flow through
the open center passage. See Figure 4. The increased
pressure in the parallel passage causes the oil to flow
through the check valve to the supply cavity. The oil
flows from the supply cavity through a section of the
spool to the rod side of the tilt cylinders. The check
valve prevents the movement of the load until the
system pressure is great enough to control the load.
Oil from the piston end of the tilt cylinders returns
through the main control valve to the hydraulic tank.

Tilt Forward

The tilt control spool that is inside the tilt spool oper-
ates during the Forward tilt function. See Figure 4.
The tilt control spool prevents cavitation in the pis-
ton end of the tilt cylinders. Cavitation occurs when
the available fluid does not fill the space in a closed
system. The high vacuum causes some of the fluid
to change to bubbles of gas. When cavitation occurs
in the tilt cylinders, the tilt forward function is not
smooth.

The tilt control spool permits the regulation of the
tilt speed by using the pressure from the hydraulic
pump.

The pressure must be 550 kPa (80 psi) on the piston
end of the tilt cylinders. The tilt control spool pre-
vents oil flow from the rod end of the tilt cylinders
until the pressure is 550 kPa (80 psi). This action
makes sure that a vacuum cannot occur at the piston
end of the tilt cylinders.

Relief Valve

The relief valve limits the maximum pressure within
the hydraulic system. The control valve can have one
or two relief valves. The primary relief valve is in-
stalled in the inlet section of the control valve and is
for the lift circuit. The secondary relief valve is for
the tilt and auxiliary circuits and is installed in the
section of the control valve with the lift/lower spool.
Both relief valves are the same in description and op-
eration. When the secondary relief valve is installed,
it is set at a lower pressure than the primary relief
valve. When the pressure in one of the hydraulic cir-
cuits reaches the relief valve setting, the relief valve
opens a path between the inlet and drain circuits.

The relief valve is a poppet valve that is pilot op-
erated. There are four poppet spools in this valve.
Spools C, D, and E are used for pressure relief.
(Spool K is for vacuum relief and is not used in this
application.) This relief valve gives almost constant
relief pressure over the range of the hydraulic pump
flow. The sequence of operation is described in Fig-
ure 5.

SOLENOID VALVE FOR AUXILIARY
FUNCTION

When used, this valve is installed on the front of the
cowl. See Figure 6. Together with one of the auxiliary
sections of the main control valve, the solenoid valve
provides a fifth function. Header hoses are used to
connect the attachment to the solenoid valve.

The solenoid valve is electrically actuated by a button
on the lever for the optional hydraulic functions. The
button operates only when the lever is in the left posi-
tion. (The lever is spring-loaded to the left position.)
When the button is not depressed, the lever operates
the third function the same as without the button.
When the button is depressed with the lever in the
left position, the solenoid valve controls the fourth
function. When the lever is moved to the right, it op-
erates the fifth hydraulic function.

Operation

STEP 1 = THE RELIEF VALVE IS CLOSED BETWEEN THE HIGH PRESSURE INLET (HP) AND THE LOW
PRESSURE (LP) DRAIN. HIGH PRESSURE OIL ENTERS THE PASSAGE AT C. THE DIFFERENCE IN
AREA BETWEEN DIAMETERS A AND B HOLDS THE POPPET SPOOL D AGAINST THE VALVE SEAT.

STEP 2 = THE OIL PRESSURE IN THE HIGH PRESSURE INLET BECOMES GREATER THAN THE
SPRING FORCE OF THE PILOT POPPET E. THE PILOT POPPET E IS PUSHED FROM ITS SEAT. OIL
FLOWS AROUND THE POPPET E AND THROUGH THE PASSAGES TO THE DRAIN.

STEP 3 = WHEN PILOT POPPET E OPENS, THE LOSS OF OIL PRESSURE BEHIND POPPET C CAUSES
POPPET C TO MOVE AGAINST POPPET E. THIS MOVEMENT STOPS THE FLOW OF OIL THROUGH C
AND CAUSES A LOWER PRESSURE BEHIND RELIEF VALVE POPPET D.

STEP 4 = THE DIFFERENCE IN PRESSURE ON EACH SIDE OF POPPET D CAUSES POPPET D TO
OPEN. THE HIGH PRESSURE OIL THEN HAS A DIRECT PATH TO THE LOW PRESSURE DRAIN.

REMOVE AND DISASSEMBLE

WARNING

Lower the mast before disconnecting lines
from the control valve to prevent the mast
from lowering suddenly.

Disconnect lines at control valve. Put caps on
open lines.

Disconnect linkage at spools.

Remove bolts that hold main control valve to
frame.

NOTE: Disassemble the main control valve as nec-
essary for repairs. Most repairs to the main control

valve are the adjustment of the linkage and the re-
placement of O-rings to stop leaks. The passages in
the tilt spool are small and can need cleaning if the
hydraulic oil becomes dirty. The section normally
must be replaced if the spool or valve section is dam-
aged.

Remove end cap from valve section. Carefully
pull spool from valve section.

Do not remove

spring retainers unless a spring must be re-
placed.

The valve sections can be separated when the
three through bolts are removed.

The check

valves are held in the valve body by the next
section.

a. Install two mount bolts through valve.

b. Make sure all four grommets are in the cowl,

then install valve on grommets.

Tighten

nuts.

Install supply and return hoses and header
hoses on solenoid valve.

If a bad coil was removed, install a new coil as
shown in Figure 9. Make sure the coil terminals
are in the correct position. Tighten screws for
end plate to 4.5 to 5.6 N•m (40 to 50 lbf in).

NOTE: Make sure wires and diode are connected as
shown in Figure 7. The diode must be installed with
color-code band toward positive terminal.

Connect diode assembly with red and white wires
at coil terminals.

TROUBLESHOOTING

If the solenoid valve does not operate, do the follow-
ing steps:

Check the 7.5 amp fuse for the solenoid valve on
the fuse panel.

Check for loose electrical connections:

a. Ignition switch: Check the black wire at the

accessory terminal of the switch connector
body.

b. Control knob button:

Remove snap ring

and knob cover. Check wire connectors and
switch connections.

Solenoid valve coil: Remove coil cover. See
Figure 7.

Check diode connections to coil

terminals. Check connections of the red and
white wires to diode assembly terminals.
Check connection of the black wire.

d. Cowl ground stud: Make sure there are no

loose ground wires.

Remove diode assembly. Test diode with an ohm-
meter for high resistance in one direction and no
resistance in the other direction. If there is no re-
sistance or infinite resistance in both directions,
replace diode.

NOTE: Make sure the wires and the diode are con-
nected as shown in Figure 7. The diode must be in-
stalled with the color-code band toward the positive
terminal.

Disconnect the red and white wires from the
diode assembly terminals.

Connect voltmeter

across the wire terminals, check for current
when control knob button is depressed.

a. If there is no current, check wiring for short

circuits.

b. If there is current, test coil. See Step 5.

Test coil for continuity by connecting an ohmme-
ter lead to each coil terminal. Put ohmmeter on
the R × 1 scale.

a. If there is no ohmmeter reading, the coil is

bad. Replace coil.

b. If there is an ohmmeter reading, the coil is

good.

If the coil is good, but the solenoid

valve does not energize when the button is
depressed, the solenoid valve is bad. Replace
solenoid valve assembly.

Pressure Relief Valve Check and Adjustment

NOTE: The control valve can have two relief valves: a
primary relief valve and a secondary relief valve. The
primary relief valve is always on the inlet section of
the control valve. The secondary relief valve is on the
