TECHNIQUES OF OPERATION

The best way to get acquainted with how
your winch operates is to make test runs
before you actually use it. Plan your test in
advance. Remember, you hear your winch,
as well as see it operate. Get to recognize
the sounds of a light steady pull, a heavy
pull, and sounds caused by load jerking or
shifting. Gain confidence in operating your
winch and its use will become second
nature with you. The uneven spooling of
rope, while pulling a load, is not a problem,
unless there is a rope pileup on one end of
drum. If this happens reverse the winch to
relieve the load and move your anchor point
further to the center of the vehicle. After the
job is done you can unspool and rewind for
a neat lay of the rope.

TO UNLATCH CLUTCH

Run winch in the reverse (reel out) direction
until the load is off the rope. Grasp handle
firmly, while pushing on the top of the
handle with the thumb for leverage, lift until
pin clears latching slots.

TO ENGAGE CLUTCH

Unlatch and pull handle toward “IN” position
as far as it will go. In order to attain full
engagement, internal elements of the clutch
must be aligned. This alignment will take
place when the rope drum or rope drum
shaft turns a maximum of 1/4 revolution.

For winching in the load the clutch must be
fully engaged with the drum.

TO ENGAGE CLUTCH

There must be a minimum of 0,5 m (1.5 ft)
of slack in the rope before attempting to
engage the clutch. This will allow the drum
to rotate a minimum of 1/4 turn allowing
engagement of the clutch before pulling the
load. With this slack in the rope, exhaust air
pressure from the air shift cylinder. Run the
winch in the “IN” direction until the clutch
starts to turn. Clutch must be fully engaged
before starting the winch operation.

TO DISENGAGE CLUTCH

Run winch in the “OUT” direction until there
is no load on the rope. Apply 4,8-6,2 bar
(70-90 psi) to the air shift cylinder to
disengage the clutch. Do not disengage

the clutch under load.

TO ENGAGE CLUTCH

Raise the handle so the notch clears the
bracket, and pull handle out as far as it will
go. The clutch will automatically spring into
engagement and latch when the clutch
aligns with the drum shaft. In order to attain
full engagement, internal elements of the
clutch MUST be aligned. This alignment will
take place when rope drum or rope drum
shaft turns a maximum of 1/4 revolution.
Do not attempt to pull a load unless notch in
shifter shaft is securely latched. Keep clear
of spring-loaded handle during automatic
engagement.

TO DISENGAGE CLUTCH

Raise handle so notch clears bracket.
Push handle in and latch the shaft notch
onto bracket. Do not disengage the clutch

WINCH MAINTENANCE

Adhering to the following maintenance
schedule will keep your winch in top condition
and performing as it should with a minimum
of repair.

A. WEEKLY

1. Check the oil level and maintain it to the oil
level plug. If oil is leaking out, determine
location and repair.

2. Check the pressure relief plug in top of the
gear housing. Be sure that it is in good
operating condition so that hot oil gasses
may escape.

3. Lubricate rope with light oil.

engaged position and that it is pulled fully
away from the rope drum and latched
when disengaged.

3. Check the winch mounting bolts. If any are
missing, replace them and securely tighten
any that are loose to recommended
torque. Make sure to use only grade
5 bolts or better.

4. Check the torque setting of the oil cooled
holding brake. Make any adjustments
required, following the procedure
described in ADJUSTING THE OIL
COOLED HOLDING BRAKE in the
Owner's Manual.

5. Inspect the rope. If the rope has become
frayed with broken strands, replace
immediately.

C. ANNUALLY

1. Drain the oil from the winch annually or
more often if winch is used frequently.
Fill the winch to the oil level plug with clean
kerosene. Run the winch a few minutes
with no load in the reel in direction.
Drain the kerosene from the winch.
Refill the winch to the oil level plug with all
purpose E.P. 140 gear oil.

2. Inspect frame and surrounding structure
for cracks or deformation. Gear wear can
be estimated by rocking the drum back

and forth and if necessary drain oil and
remove cover for closer inspection.

3. Adjust the oil cooled holding brake. See

ADJUSTING THE OIL COOLED
HOLDING BRAKE on page 7.

B. MONTHLY

1. Lubricate the various grease fittings
located in the ends of rope drum shaft, end
bearing, clutch housing or clutch operating
linkage. Any good grade of moly-disulfide
containing grease is acceptable.

2. Check the action of the locking ring,
making sure it is spring loaded and free to
move fully against the rope drum in the

WINCH MOUNTING

It is most important that this winch be
mounted securely so that the three major
sections (the clutch housing end, the rope
drum and the gear-housing end) are properly
aligned.

This H-89 Dow-Lok® series winch is furnished
with 13 x 76 x 102 mm (1/2 x 3 x 4 in) high­strength steel angles.

ROPE INSTALLATION



The Ramsey Model H-89 Dow-Lok
One pocket is for installation with the wire rope wound over the drum. The other pocket is
for an underwound wire rope.

1. Slide the wire rope through narrow end of the pocket against the drum flange.

2. Wrap the wire rope around the anchor "puck" and pull the wire rope and anchor back
into the wide end of the pocket.

3. Use a soft hammer to drive the back side of the wire rope, firmly seating the wire rope
and anchor into the pocket.

The wire rope can easily be removed from the drum by driving the anchor out the wide end
of the pocket. While keeping tension on end of rope, carefully run the winch in the "reel-in"
direction spooling all the rope onto the rope drum. Take care to form neatly wrapped
layers.

ADJUSTING THE OIL COOLED HOLDING
BRAKE

The oil cooled, fully adjustable, automatic holding
brake operates in the worm housing lubricant, all
parts being submerged in oil. The brake can be
adjusted as follows:

1. Loosen the lock nut on the adjusting screw.

2. Tighten the brake by turning the adjusting

screw clockwise. CAUTION: Only 1/4 turn is

usually required to adjust the brake.

Over-tightening can cause overheating, and
damage to the brake parts. Tighten the lock
nut after adjustment is completed.

If the brake does not respond to adjustment, then
a new leaf spring and brake disc is needed.

A torque wrench can be equipped with a special
adapter to fit the input shaft (worm) of the winch.
The adapter can be made by welding a nut to the
end of a piece of tubing as shown in the following
figure. After welding the cap and nut to the tubing,
slot the tubing, as shown. This will allow the
special adapter to slide over the keyway and will
then act as a large socket.

A torque wrench can the be used to apply the
proper torque. Turn the torque wrench so that the
drum turns in the spool out direction or lowering
direction. The torque rating for the brake on the
Model H-89 Dow-Lok® should be 68 to 75 Nm (50
to 55 ft- lb). If torque wrench does not show the
proper value as it turns, then the worm brake
adjusting bolt should be turned clockwise 1/4 turn.
Each time the adjusting bolt is turned, checked
the torque reading. Continue this procedure until
the proper torque reading is achieved, then
tighten the lock nut.

SERVICING OF THE OIL COOLED
HOLDING BRAKE

1. Remove the drain plug and drain the worm
gear oil from the worm housing.

2. Back off the lock nut, then the adjusting
screw, both two turns or more by turning them
counter-clockwise.

3. Remove the cover mounting screws.

4. Remove the cover along with coil spring and
leaf spring.

5. Remove the retainer plate, composition brake
disc, cam plate and balls. Note which slots
balls are in, #1 or #2. This will determine the
brake engagement direction.

6. Insert parts as follows:

a) Composition brake discs are 6,4 mm (1/4")
thick when new. Replace if thinner than 4,8
m (3/16”) or if surfaces are glazed or burnt.

b) Inspect the flat, ground surface of the
camplate and retainer plate for glazing,
warpage, or other damage. Glazing can be
removed by scraping carefully.

c) Inspect the leaf spring. It should be

sure that balls are secure, between cam slots and hub slots. Install brake disc.

3. Install retainer plate, smooth side toward brake disc.

4. Install the gasket on the cover with a small amount of grease or sealer.

5. The coil spring goes over the adjusting screw on the inside of the cover.

6. Install the notches of the leaf spring on the pins protruding through the cover.
The hollow side of the leaf spring goes toward the brake.

7. Install brake housing cover, making sure the protruding pins go through the leaf spring
and into the holes in the retainer plate.

8. Bolt cover into place with the mounting screws. Install drain plug and add 1,8 liters
(3-3/4 pints) of all purpose E.P. 140 oil.

9. Turn winch in the hoisting direction at least one turn of the input shaft.

10. Turn the adjusting screw in until it is finger tight.

TEST FOR PROPER HOLDING BRAKE ASSEMBLY

After the brake has been adjusted to the proper torque setting, disengage clutch. Start
vehicle engine and run winch in the reel in (pulling direction). Allow winch to run in this
direction for one minute.

Place your hand on the safety brake housing. If housing is not hot to the touch then run
winch in the reverse direction (rope out) for one minute. Brake housing should begin to
heat.

When these conditions exist, proper installation has been made. If heating becomes
noticeable when running the winch in forward rotation (pulling direction), the brake should
be again disassembled. When disassembled, place the brake balls in the alternate set of
slots in the cam plates, then carefully follow the instructions for re-assembling and
checking the brake.

TECHNIQUES D’UTILISATION

Pour vous familiariser avec votre treuil, il est
vivement conseillé de l’essayer avant de
vraiment l’utiliser. Préparez l'essai. N’oubliez pas
que vous entendez votre treuil autant que vous le
voyez fonctionner. Apprenez à reconnaître le son
d'une traction légère et régulière, celui d'une
lourde charge ou encore celui provoqué par des
à-coups ou une déviation de la charge. Prenez
l’habitude de faire fonctionner votre treuil et tout
deviendra automatique. L’enroulement irrégulier
du câble lors de la traction d’une charge ne
présente pas de problème sauf en cas
d’accumulation du câble sur un côté du tambour.
Dans ce cas, inversez le fonctionnement du treuil
afin de soulager la charge et déplacez votre point
d’attache vers le centre du véhicule. Une fois le
travail terminé, vous pouvez dérouler le câble et
l’enrouler à nouveau d’une manière régulière.

position enclenchée (la position « IN »), soit en
position désenclenchée (la position « OUT »),
par une goupille qui s’insère dans le trou
correspondant à la partie inférieure du levier
d’embrayage.

POUR DÉBLOQUER L’EMBRAYAGE

Faites fonctionner le treuil en marche arrière
(déroulement) afin de dégager la charge du
câble. Saisissez fermement la poignée tout en
poussant sur le dessus avec le pouce, puis
soulevez jusqu'à ce que la goupille se dégage
des trous de blocage.

POUR ENCLENCHER L’EMBRAYAGE

Débloquez la poignée et tirez-la autant que
possible en position rentrée « IN ».Afin de
garantir un enclenchement complet, les éléments
internes de l’embrayage doivent être alignés. Cet
alignement s'obtient lorsque le tambour du câble
ou son arbre tourne au maximum d'un quart de
tour. L’embrayage s’enclenche automatiquement

N’essayez pas de soulever de charge si la
goupille n’est pas complètement dans les
trous de position rentrée « IN ». Restez à
distance de la poignée à ressort pendant
l'enclenchement automatique.

POUR DÉGAGER L’EMBRAYAGE

Débloquez et poussez la poignée en position
sortie « OUT », puis insérez la goupille dans les
trous de blocage. Ne désenclenchez pas
l’embrayage en présence d’une charge.

d’enrouler librement et d’enclencher l’embrayage
du tambour du câble. Lorsque l'embrayage est
désenclenché, le câble peut être déroulé
librement du tambour à la main. Pour treuiller
une charge, l’embrayage doit être complètement
enclenché sur le tambour.

POUR ENCLENCHER L’EMBRAYAGE

Avant d’essayer d’enclencher l’embrayage, veillez
à ce que le câble ait au moins 50 cm de mou.
Ceci permettra au tambour de tourner d’au moins
un quart de tour et d’enclencher ainsi
l’embrayage avant de tirer la charge. Ce mou
dans le câble permet d’éliminer la pression d'air
du cylindre d’embrayage pneumatique. Faites
fonctionner le treuil en position d’enroulement
jusqu'à ce que l’embrayage commence à tourner.
L’embrayage doit être entièrement enclenché
avant de lancer le fonctionnement du treuil.

POUR DÉGAGER L’EMBRAYAGE

Faites fonctionner le treuil en direction de
déroulement jusqu’à l’absence de charge sur le
câble. Appliquez une pression de 480 à 620 kPa
au niveau du cylindre de l’embrayage
pneumatique pour désenclencher l’embrayage

Ne désenclenchez pas l’embrayage en

POUR ENCLENCHER L’EMBRAYAGE

Soulevez la poignée jusqu’au déblocage du
support et la tirer jusqu’en fin de course.
L’embrayage s’enclenche automatiquement et se
verrouille lorsqu’il s’aligne sur l’axe du tambour.
Afin de garantir un enclenchement complet, les
éléments internes de l’embrayage DOIVENT être
alignés. Cet alignement s'obtient lorsque le
tambour du câble ou son arbre tourne au maximum
d'un quart de tour. N’essayez pas de treuiller une
charge tant que la rainure de l’arbre de
l’embrayage n’est pas solidement verrouillée.
Restez à distance de la poignée à ressort pendant
l'enclenchement automatique.

POUR DÉGAGER L’EMBRAYAGE

ENTRETIEN DU TREUIL

L’observation du calendrier de maintenance
suivant vous permettra de maintenir votre treuil en
bon état et garantira un fonctionnement avec un
minimum de réparations.

A. ENTRETIEN HEBDOMADAIRE

1. Vérifiez le niveau d’huile et maintenez-le au
niveau du bouchon. En cas de fuite d’huile,
déterminez l’emplacement de la fuite et réparez.

2. Vérifiez le bouchon d’échappement en haut de
la boîte d’engrenages. Assurez-vous qu’il
fonctionne bien afin que les gaz issus de l’huile
chaude puissent être évacués.

3. Lubrifiez le câble avec de l’huile légère.

B. ENTRETIEN MENSUEL

1. Lubrifiez les divers graisseurs situés aux
extrémités de l’arbre du tambour du câble, le
roulement d’extrémité, le carter d’embrayage
ou la tringlerie d'embrayage. Vous pouvez
utiliser toute graisse de bonne qualité
contenant du bisulfure de molybdène.

2. Vérifiez le fonctionnement de la bague de
blocage en vous assurant qu’elle est montée
sur ressort et qu’elle peut se déplacer
librement contre le tambour du câble en
position enclenchée. Vérifiez également qu’elle

se dégage bien du tambour et se bloque bien
lors du désenclenchement.

3. Vérifiez les boulons de fixation du treuil.
Remplacez tout boulon manquant et serrez
fermement les autres sous le couple de serrage
recommandé. Veillez à utiliser uniquement des
boulons de classe 5 ou supérieure.

Vérifiez le réglage du couple de serrage du frein de

4.
maintien de charge refroidi à l’huile. Procédez à tout
réglage nécessaire, conformément à la procédure
décrite dans la section Réglage du frein de maintien
de charge statique refroidi par huile du manuel
de l’utilisateur.

5. Examinez le câble. Tout câble dénudé ou
effiloché doit être remplacé immédiatement.

C. ENTRETIEN ANNUEL

1. Le treuil doit être vidangé une fois par an ou
plus souvent en cas d’usage fréquent.
Remplissez le treuil de kérosène propre
jusqu’au niveau du bouchon de niveau d’huile.
Faites fonctionner le treuil quelques minutes
sans charge dans le sens de l’enroulement.
Éliminez le kérosène du treuil. Remplissez le
treuil d’huile pour engrenages E.P. 140
polyvalente jusqu’au bouchon de niveau d’huile.

2. Examinez le châssis et l’armature qui l’entoure
afin de déceler toute déformation ou fissure
éventuelle. Pour évaluer l’usure des
engrenages, secouez le tambour d’un

mouvement de va-et-vient et, si nécessaire,
vidangez l'huile et déposez le capot pour un
examen plus approfondi.

3. Réglez le frein de maintien de la charge
statique refroidi par huile. Consultez la section

Réglage du frein de maintien de charge
statique refroidi par huile à la page 31.
