Drain the kerosene from the winch. Refill
the winch to the oil level plug with all pur-
pose E.P. 140 gear oil. Inspect frame and
surrounding structure for cracks or deforma-
tion. Gear wear can be estimated by rock-
ing the drum back and forth and if nec-
essary 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.
This H-800 Dow-Lok® series winch is fur-
nished with 1/2 x 3-1/2 x 3-1/2 high-
strength steel angles.
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.
Carefully run the winch in the "reel-in" direc-
tion, keeping tension on end of cable, spool
all the cable onto the cable drum, taking
care to form neatly wrapped layers.
ADJUSTING THE OIL COOLED WORM
BRAKE
The oil cooled, fully adjustable, automatic
safety 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 adjust-
ed 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 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 low-
ering 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, checked the torque
reading. Continue this procedure until the
proper torque reading is achieved. Then
tighten the lock nut.
