Wire rope (winch line) may be old, damaged or weakened by such defects as kinks, cuts, extreme bends or
loops. Such conditions are potentially dangerous and detrimental to safe operation of the winch. The wire
rope must be routinely inspected at regular intervals and replaced when worn. See Maintenance Section 6.01
for replacement criteria.
Make certain that the winch clutch is positively engaged before starting the pull.
Operate the winch as smoothly as possible. Sudden jerking pulls can place extreme loads on equipment, caus-
ing damage or injury.
Do not operate the winch at speeds faster than necessary.
When pulling in, do not allow the wire rope to build up in one location on the drum. This can cause wire rope
"roll-over" and possible erratic, damaging pulls.
Loads on the winch, winch line or extension shaft must not exceed their rated capacity.
3. INSTALLATION
3.01 GENERAL - The following procedures are recommended to assure safe, trouble-free operation:
For typical automotive applications, the winch is normally mounted behind the chassis cab in the forward section
of the body load area, directly to the chassis frame. The two SAE rated mounting brackets supplied with the Ad-
ams
®
Model CD3 Continuous Duty Winch are of a "bolt-on" design with no welding required.
For standard installations, orient the winch assembly on the chassis frame so that the level-wind is facing rearward
and the drum shaft is projecting toward the right (curb) side as viewed from the rear of the vehicle looking for-
ward. The winch must be positioned on the truck chassis with the centerline of the drum upon the centerline of the
chassis. Sufficient clearance should be allowed between the front body panel or other restrictive members and the
winch to permit normal maintenance.
The direction of drum rotation for pulling in when the winch is an over-wind unit is clockwise when viewed from
the right side of the vehicle. The wire rope is wound onto the drum from the top.
Attach the mounting brackets to the bottom of the winch frame on each side using the quantity ten (10) ¾ - 10 x
2¾ HHCS grade 8 bolts with disc spring washers and two (2) 1 - 8 SHCS bolts with disc spring washers and steel
backup plates. Finger tighten only.
Clamp the mounting brackets to each side of the truck chassis, then tighten the ten (10) ¾ - 10 bolts one half turn
so the bracket is tight against the bottom of the winch frame. NOTE: Do not torque to required specifications at
this time.
Using the

in. diameter pilot holes, transfer the hole locations onto the truck chassis. The clearance drill diame-
ter of

in. is recommended for the
5
/
8
in. diameter bolts supplied in the bolt kit from the factory. After the clear-
ance diameter is drilled, install the bolts in each hole and hand tighten with a lock washer and nut.
When all of the bolts, lock washers, and nuts are in place, torque to 180 ft.-lbs. all twenty (20)
5

- 18 grade 8
bolts. Then torque to 380 ft.-lbs. (515 N·m) all ten (10) ¾ - 10 bolts. Then torque to 450 ft.-lbs. (610 N·m) both 1
- 8 bolts. A special ¾ in. hex key P/N 26288 is supplied for use with a ¾ in. socket and ¾ in. drive torque wrench
to properly tighten the 1 - 8 bolts.
When using Huckbolt
®
fasteners instead of the factory bolts, drill the mounting brackets and truck chassis with the
manufacturer's recommended clearance drill.
It is recommended that the winch be directly mounted only to the truck chassis frame. It is not recommended to
mount the winch to any other structural member, as on a sub-frame, without first contacting the factory for specific
application engineering support.
