Sufficient clearance should be allowed between the front body panel or other re-
strictive members and the winch to permit normal maintenance.
For standard installations, place the winch assembly on the chassis frame so that the
levelwind is facing rearward and the drum shaft is projecting toward the right or
curb side.
The normal direction of drum rotation for pulling in is clockwise when viewed
from the right side of the vehicle. The wire rope is wound onto the drum from the
top. Deviation from this standard mounting procedure could cause severe heat and
operational difficulties.
With the two mounting brackets on the winch frame, locate the winch drum center-
line on the chassis frame center-line. Slide the mounting brackets tight to the chas-
sis frame. Using the eight %" diameter pre-drilled holes in each bracket as a guide,
finish drill all holes in both brackets for a tight fit, using the %" -18 x 2" long class
five hardened steel bolt furnished in the winch mounting kit.
Weld both sides of the mounting bracket to both winch frame rails. Do not weld
the mounting brackets to the chassis frame.
All of the mounting hardware and, if ordered, the drum shaft extension, are
shipped in a parts box attached to the winch or shipping crate.
To protect the entire winch assembly against rust, various parts are sprayed with a
rust inhibitor and both drive housings are filled with oil when shipped from the
factory. If the winch will be placed in outside stock for an indefinite period, care
should be taken to prevent oil contamination or rust due to condensation.
CONTROLS When the winch has been mounted, consideration must be given to the control of:
Drum direction of rotation
Drum speed
Winch clutch and drag brake (disc type)
Drag brake (band or caliper type)
Because of the wide variation in the type of controls available, it is the responsibil-
ity of the dealer to furnish and install those required in the bid specifications,
whether they are conventional or automatic. This is particularly true for drum
rotation direction and speed.
On all units there is a drag brake assembly. The brake is either a disk, band or cali-
per type, depending on the date of manufacture. Disk or band type brakes are con-
trolled by a push-pull handle at the right rear of the vehicle. Caliper type brakes are
controlled by a hydraulic actuator at the left rear. For correct brake identification,
check the winch serial number, the date of manufacture and additional information
found on pages 4, 5, and 6 of this booklet.
WINCH CLUTCH
AND DRAG BRAKE
GNERERAL INFORMA-
TION SHIFTING OF THE CLUTCH SHOULD ONLY BE DONE WHEN THE DRUM
AND DRAG BRAKE ROTATION HAS STOPPED.
When shifting from the disengaged to the engaged position, the operator should
make certain that full engagement is accomplished. Normally, proper engagement
is identified by a characteristic clang of the clutch plate and the drum.
When the winch clutch is disengaged, the drum will rotate freely on the drum
shaft. It should also be noted that power can still be transmitted through the drum-
shaft to the drum shaft extension to drive a capstan or reel.
Under present mechanized, high winch line speed conditions, it is extremely impor-
tant to operate the disc, band or caliper type drag brake properly, maintaining suffi-
cient tension on the wire rope. This will enable the levelwind assembly to operate
properly, minimize over-spinning of the drum and help provide suitable coils and
lays of wire rope.
THE DRAG BRAKE IS USED TO CONTROL THE DRUM SPEED ONLY. IT IS
NEVER TO BE USED TO HOLD THE LOAD.
