Safety Summary
• Make sure ground personnel are in plain view of the
operator, and at a distance of at least 1½ times the
working length of the wire rope.
• Make sure that any hand signals used by ground
personnel are clearly defined and understood by
everyone involved.
• Do not attempt to “jerk” or “shock” a load free. Doing
so can cause loads in excess of the rated capacity
of the wire rope, winch, or mounting hardware.
• Replace any parts only with genuine Allied Winch
parts. Refer to Parts Manual 599039W.
• Maintain a minimum of three (3) complete wraps
of wire rope on the drum for normal operation. It
may help to paint the last five wraps of wire rope
a contrasting color, to serve as a visual indicator.
• Do not handle wire rope with bare hands. Wear
leather gloves at all times.
• Align the tractor with the load to prevent side loading
the winch, and to maintain even spooling of the
wire rope.
• If applying tension to the wire rope manually during
spooling:
xensure that the operator is winching in slowly,
xkeep your hands and clothing well clear of any
rollers or the winch drum,
xdo not maintain tension by letting the wire rope
to slip through your hands,
xuse a hand-over-hand technique to maintain
tension.
• Be aware of the ground conditions, and make sure
the ground and tractor are stable enough to pull
the intended load.
• Do not attempt to pull loads in excess of the rated
capacity of the winch.
• Keep yourself informed of any applicable codes,
regulations and standards for the job.
• Your winch may have temperature shut-off system
for protection of tractor and winch. Manual override
of high temperature shut-off will cause damage to
tractor and winch.
• This winch is neither intended, designed, nor rated
for any application involved in the lifting or moving
of personnel.
• Use only the lubricants listed in the Recommended
Oil List. See page 1-4.
• Do not weld on any part of the winch. Contact Allied
Systems if weld repairs are needed.
• The hydraulic system must be kept clean and free
of contamination at all times.
• Be aware of the hazards of pressurized hydraulics:
xWear personal protective equipment, such as
gloves and safety glasses, whenever servicing
or checking a hydraulic system.
xAssume that all hydraulic hoses and components
are pressurized. Relieve all hydraulic pressure
before disconnecting any hydraulic line.
xNever try to stop or check for a hydraulic leak
with any part of your body; use a piece of
cardboard to check for hydraulic leaks.
xSmall hydraulic hose leaks are extremely
dangerous, and can inject hydraulic oil under
the skin, even through gloves.
xInfection and gangrene are possible when
hydraulic oil penetrates the skin. See a doctor
immediately to prevent loss of limb or death.

Introduction
This service manual is for the H6H winch. The following
information is included in this manual:
Section 1. General includes operation descriptions
of systems and components as an aid for
troubleshooting and repair.
Section 2. Troubleshooting lists common problems
and the possible causes and corrections.
Section 3. Maintenance provides a guide for
periodic maintenance, checks and adjustments.
Section 4. Repairs describes the removal,
disassembly, assembly, and installation of the winch.
Description
The H6H Winch is a Power Forward (LINE-IN) and Power
Reverse (LINE-OUT) winch. The winch is powered by an
internal hydraulic motor connected to the tractor hydraulic
system. Oil flow and pressure are converted to rotational
energy by the winch motor. Motor torque is transmitted
through a holding brake, a planetary speed reducer and
two gear reductions to the drum. Hydraulic oil is supplied
by the tractor mounted auxiliary pump circuit and utilizes
oil, filtration and cooling provided by the tractor circuit. Flow
to the winch is controlled by a control lever and electrical
switches located at the tractor’s control station.
The FREESPOOL function permits the wire rope to be
pulled from the drum. The BRAKE-OFF function, as an
option, permits the wire rope to be pulled from the drum
under increased resistance.
The H6H winch has a maximum rated line pull capacity
of 27,200 kg (60,000 lb.) when there is one layer or less
of wire rope on the drum. When there is more than one
layer of wire rope on the drum, the line pull is reduced.

Gear Train (See Fig. 1-7)
The tractor pump drives the hydraulic motor. Torque from
the hydraulic motor is transmitted through a holding brake,
planetary speed reducer and two gear reductions to the
drum.
A dental clutch with splines engages the drum pinion gear
and the intermediate gear. The operator can disengage
the dental clutch with an electric switch to engage the
FREESPOOL feature.
A drum gear engages the drum pinion gear and is
connected to the drum. When power is applied to the
gear train, the drum will rotate in the forward or reverse
direction.The drum adapter connects the drum to the drum
gear. The other side of the drum runs on roller bearings
held by the drum shaft. The drum shaft is connected to
the winch case.

FREESPOOL Operation (See Fig. 1-9 & 1-10)
The FREESPOOL arrangement allows mechanical
disengagement of the drum gear from the remainder of the
gear train.When FREESPOOL is selected, a hydraulically-
actuated sleeve disengages the dental clutch from the
intermediate shaft. The drum is now disconnected from
the brake, and the winch cannot support a load.
WARNING
FREESPOOL should not be used if there
is a load on the wire rope. An uncontrolled
release of the load will occur. Loss of the
load can result in injury and/or equipment
damage.
The yellow indicator panel on the selector switch lights
when the winch is in FREESPOOL. If equipped with
BRAKE-OFF, the red indicator in the BRAKE-OFF switch
will also light even though that switch is in the off position.
NOTE: The dental clutch may not disengage if there
is a load on the wire rope.

Operation & Control (See Fig. 1-11)
The H6HT winch is designed to operate on a load sense,
pilot operated hydraulic system.When the tractor is running,
the winch is ready to operate but no oil is flowing to the
winch. Control (pilot) pressure is present at the winch.
The control lever and electrical switches are used to select
the following operations (not all winches are equipped
with all options):
• BRAKE-ON (spring-centered position)
• LINE-IN
• LINE-OUT
• BRAKE-OFF (optional)
• FREESPOOL
The tractor must be running and the auxiliary hydraulic
function switch, if equipped, must be on. LINE-IN, LINE-
OUT and BRAKE-ON are controlled by a proportional
control lever.
When the control lever is in the BRAKE-ON or centered
position, the holding brake is automatically applied.
Pushing the lever away from the operator releases the
brake, and reels the wire rope off the drum (LINE-OUT).
Pulling the lever towards the operator releases the brake,
and reels the wire rope onto the drum (LINE-IN). Releasing
the lever causes it to return to the BRAKE-ON position,
which stops the drum rotation and applies the holding
brake. Moving the lever a small amount results in slow wire
rope movement for inching control. Line speed increases
proportionally as the lever is moved farther.
The switch panel contains two rocker switches to control
FREESPOOL and BRAKE-OFF. The tractor must be
running to supply hydraulic power to operate these
functions. A light shows when a switch is on.
The FREESPOOL and BRAKE-OFF switches incorporate
a lock to prevent inadvertent actuation. The slide lock
must be released before the switch can be turned on. In
BRAKE-OFF, hydraulic pressure is applied to release the
brake-off clutch. As wire rope is pulled from the winch,
the turning drum back-drives the winch gear train to the
brake-off clutch. The winch motor, brake, and planetary
reducer remain stationary. Mechanical drag through the
gear train and viscous drag in the brake-off clutch keep the
wire rope from bird-nesting as it is spooled off the drum.
CAUTION
Before operating the winch in LINE-IN or
LINE-OUT mode, ensure the FREESPOOL and
BRAKE-OFF lights are not illuminated. The
winch will not operate.

Motor (See Fig. 1-13)
The hydraulic motor is a bent axis variable displacement
motor. The default position of the motor is maximum
displacement. Control pressure operates a servo that
proportionally reduces motor displacement. At 261 psi
Figure 1-13 Motor Shaft Assembly (Shown with BRAKE-OFF Option)
control pressure, the motor begins to ramp to minimum
displacement. At higher motor pressure, a pressure
compensator will shift the motor back to maximum
displacement.
