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.
Insert the end of cable, opposite hook end, into the 11/16" dia. hole in drum barrel. Secure
cable to drum barrel, using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
Carefully run the winch in the "reel-in" direction, 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 worm brake operates in the worm housing lubri-
cant, 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 spe-
cial 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 proce-
dure until the proper torque reading is achieved. Then tighten the lock nut.
