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 cable, while pulling a load, is not a problem, unless there is a cable 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 cable.
The Dow-lok® clutch provides free-spooling and clutch engagement with the cable drum. With the clutch disengaged, the cable can be free-spooled off the drum. For winching in the load the clutch must be fully engaged with the
drum.
The clutch is latched into either the engaged “IN” position, or the disengaged “OUT” position, by a pin at the bottom
of the shifter handle which fits into the latching slots.
TO UNLATCH CLUTCH
Run winch in the reverse (reel out) direction until the load is off the cable, grasp handle firmly and while pushing on
the top of the handle with the thumb for leverage, lift until pin clears latching slots.
TO ENGAGE THE CLUTCH
Unlatch and pull handle toward the “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 cable drum or cable drum shaft turns a
maximum of 1/4 revolution. The clutch will automatically spring into engagement and pin will drop into “IN” slots
when this alignment takes place. Do not attempt to lift a load unless pin is fully into “IN” slots. Keep clear of
spring-loaded handle during automatic engagement.
TO DISENGAGE THE CLUTCH
Unlatch and push handle to “OUT” position and fully insert pin into latching slots. Do not disengage the clutch
under load.
The Dow-lok®air-shifter clutch provides free-spooling and clutch engagement with the cable drum. With the
clutch disengaged, the cable can be free-spooled off the drum. For winching in the load, the clutch must be fully
engaged with the drum.
TO ENGAGE THE CLUTCH
There must be a minimum of 1 foot of slack in the cable before attempting to engage the clutch. This will allow the
drum to rotate a minimum of 1/4 turn allowing the engagement of the clutch before picking up the load. With this
slack in the cable, 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 THE CLUTCH
Run winch in the “OUT” direction until there is no load on the cable. Apply 70-90 psi to the air shift cylinder to disengage the clutch. Do not disengage the clutch under load.

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 cable with light oil.
B. MONTHLY
1. Lubricate the various grease fittings located in the ends of cable drum shaft, end bearing, clutch housing or
clutch operating linkage. Any good grade of grease containing moly-disulfide is acceptable.
2. Check the action of the locking ring. Make sure it is spring loaded and free to move fully against the cable drum
in the engaged position and that it is pulled fully away from the cable drum and latched when disengaged.
3. Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are loose. Make
sure to use only grade 5 bolts or better.
4. Check the torque setting of the oil cooled worm brake. Make any adjustments required, following the procedure
described in “Worm Brake Maintenance” in the Owner's Manual.
5. Check alignment of chain and sprockets and adjust as required to minimize wear.
6. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
C. ANNUALLY
1. Perform the following annually or more often if winch is used frequently:
• Drain the oil from the winch.
• 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.
3. Gear wear can be estimated by rocking the drum back and forth. If necessary, drain oil and remove cover for
closer inspection.
WINCH MOUNTING
It is most important that this winch be mounted securely so that the three major sections (the clutch housing end, the
cable drum and the gear-housing end) are properly aligned.
All standard H-800 Dow-Lok®series winches are furnished with recommended mounting angles. Angle size is 1/2 x
3 x 4 high strength steel angle.
CABLE INSTALLATION
The Ramsey Model H-800 "Dow-Lok"® winch has two tapered pockets cast into the drum. One pocket is for installations 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.

WORM BRAKE MAINTENANCE
ADJUSTMENT
The oil cooled, fully adjustable, automatic worm brake operates in the worm housing lubricant, all parts being submerged in oil. When the brake wears to the point that the load begins to drift, the brake can be adjusted as follows:
1. Loosen the adjusting screw lock nut.
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 over-heating, 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-800 Dow-Lok
®
should be 50 to 55 ft-lbs. 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, check the torque reading. Continue this procedure until the proper torque reading is
achieved. Then tighten the lock nut.
DIS-ASSEMBLY
1. Remove the drain plug and drain the worm gear oil from the gear 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.
6. Inspect parts as follows:
a) Composition brake discs are 1/4" thick when new. Replace if thinner than 3/16” or if surfaces are glazed or
burnt.
b) Inspect the flat, ground surface of the cam plate and retainer plate for glazing, warpage, or other damage.
Glazing can be removed by scraping carefully. Otherwise replace cam plate or retainer plate.
c) Inspect the leaf spring. It should be bowed 1/8". Replace leaf spring if flattened.

RE-ASSEMBLY
1. Press brake hub into place over worm shaft and key.
2. Assemble balls in #2 slots of cam. Use stiff grease to hold balls into place and slide cam over end of worm. Be
sure that balls are secure, between cam slots and hub slots.
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 3-3/4 pints 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 BRAKE ASSEMBLY
After the brake has been adjusted to the proper torque setting (see Adjustment section above), disengage clutch.
Start vehicle engine and run winch in the reel in (hoisting direction). Allow winch to run in this direction for one
minute.
Place your hand on the brake housing. If housing is not hot to the touch, run winch in the reverse direction (cable
out) for one minute. Brake housing should be hot to the touch.
When these conditions exist, proper installation has been made. If heating becomes noticeable when running the
winch in forward rotation (hoisting 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.

CLUTCH AIR SHIFTER ADJUSTMENT
1. Place winch assembly back into mounting frame and reattach using (8) mounting bolts and lockwashers. Torque
mounting hardware to 290 ft. lbs. each. Make sure that gear housing and clutch housing are not rubbing against
drum flanges.
2. Place air shifter assembly #5 over shifter shaft aligning clevis over flats of shaft. Secure clevis to shaft using
clevis pin #76 and cotter pin #75. Place shifter shaft in the "ENGAGED" position. With the air cylinder shaft fully
retracted, push shifter assembly toward the drum until all play is taken out of the shifter shaft. Secure shifter
assembly to clutch housing using (4) capscrews #46 (flanged hx. hd. serrated). Tighten securely, but do not
torque.
3. Hook up air (70 to 90 psi) to inlet port of air cylinder and disengage clutch. Look into the opening in the clutch
housing and verify that the locking ring and retainer plate are not making contact. Locking ring and retainer plate
must not make contact. There must be a clearance (gap) of .09 inch (max.) between the locking ring and retainer plate when the winch is fully disengaged. If there is contact, the (4) capscrews #46 should be loosened and
the plate pulled away from the drum approximately .06 inch. Tighten screws securely and check action to assure
needed clearance. Repeat adjustment procedure as needed to acquire needed gap. Shift clutch 2 or 3 times to
verify proper shifting of clutch. After final adjustment, torque (4) capscrews #46 to 18 ft. lbs. each. Attach
cover #43 using (4) capscrews #61.

assembly engage the external groove in the locking ring
(item #10). Push the clutch housing (item #20) onto the
drum shaft and latch the shifter assembly in the engaged
“IN” position. Insert the two capscrews (item #46) into
the shifter assembly.

Attach mounting angles (items #7 & 8) to winch assembly. Use capscrews (item #52 & #53) and lockwashers
(item #71). Tighten capscrews to 290 ft-lb. (393 Nm) each. Insert plug (item #87) into hole in bottom of gear
housing. Remove reducer and relief fitting on top of gear housing (items #79 & 86). Pour 3 -3/4 pints of E.P. 140 oil
into hole and replace plugs.
Check the action of the clutch by shifting and freespooling the winch drum several times. Operate the winch forward
and reverse and confirm that drum rotates.

CABLE TENSIONER OVERHAUL
If the cable tensioner needs to be overhauled, it will need to be re-assembled and adjusted for the proper freespool
effort. Do not operate the winch with the tensioner against a bare drum. The winch should only be operated
with the cable tensioner installed with at least one wrap of cable around the drum.
(1)
To remove the tensioner from the winch, remove the capscrews (item #47), lockwashers (item #68), and nuts (item
#63) that mount the tensioner to the angle. Disassemble the tensioner assembly as shown below. Replace any parts
that are worn.
(2)
Re-assemble the tensioner assembly. Mount the assembly to the angle using the spacers (item #32)
under the tensioner bracket. Center the tensioner plate (item #2) between the drum flanges using a
tape measure or scale. Tighten the mounting bolts to 87 ft-lbs. of torque.
(3)
Before increasing tension on the cable tensioner, the cable should be installed on the drum. As cable
winds onto the drum, watch the tensioner. The tensioner must be free to move without obstruction to
function properly. If the tensioner touches either drum flange, correct the problem.
(4)
To adjust the freespool effort of the tensioner, turn the adjustment nut (item #72) or the tensioner
stud (item #4). This will adjust the spring height. Start adjusting the tensioner with the spring height
at 5.50”. Disengage the winch and freespool some cable off the drum. Adjust the spring tension to
achieve the desired freespool effort that also prevents “bird nesting” of the cable.
