SCOPE - This document contains information pertinent to the Installation, Operation and Maintenance of the Adams® Model CD3 Continuous Duty Winch. The CD3 winch manufactured by General Machine Products Co., Inc. commencing in January 1, 1995 differ significantly from prior generations of Adams CD Winches in equipment design and components. To obtain information on earlier model CD, LCD or UG winches, please contact the factory for the appropriate manual. 1.
winch. The brake disc rotor is mounted at the factory on the clutch end drum flange. The remote actuator, reservoir, and flexible hose section are shipped loose with other winch mounting hardware in the parts box. These components are to be installed by the dealer or truck body builder. The closed circuit hydraulic system is shipped void of any fluid. Prior to operation, fill the system with only the exact type of fluid that was originally specified for your winch.
The maximum allowable pull of the standard drum shaft extension is 1,500 pounds (6,7 kN) using a standard 7 in. (18 cm) diameter capstan (GMP P/N 10727). Allowable pulls will be less when using a larger diameter accessory and/or using a longer drum shaft extension. See the table below. Table: Maximum allowable pulls on a standard drum shaft extension equipped with a 7" diameter capstan and corresponding body widths: Body Width in. m Allowable Pull lbs. kN 92 94 96 98 100 1500 1425 1350 1275 1200 2.
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.
CAUTION - DO NOT WELD THE MOUNTING BRACKETS TO THE CHASSIS FRAME. All of the mounting hardware and the drum shaft extension are shipped in a parts box attached to the winch or shipping crate. IMPORTANT - To avoid corrosion problems when storing winches outside the parts boxes MUST be removed and stored in an indoor area. 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.
Recommended hydraulic line diameters are: ♦ Pump to control valve: 1¼ in. (32 mm) ♦ Control valve to tank: 1¼ in. (32 mm) ♦ Control valve through power beyond to hydraulic system: 1¼ in. (32 mm) ♦ Control valve work ports to Tri-Drive motor ports: 1 in. (25 mm) Suggested Filtration, based on the hydraulic motor requirements, is 20 to 30 micron (nominal) filters. Consult the filter supplier for specific filter recommendation. The hydraulic motor case drain (¼ NPT) should be ported to tank.
are magnetically activated and while they work on the same principle as Hall effect sensors, they are exceedingly sensitive. The sensors are 100% solid-state devices with no moving parts to wear, break, bounce or stick and they are fully encapsulated in plastic resin. The sensors must be wired as per drawing no. 25777.
The importance of cleanliness during installation cannot be over-emphasized. ♦ Caliper Drag Brakes on Adams Winches may be specified by the customer for brake fluid only or hydraulic oil only. Installation and service personnel must verify which fluid to use for a specific winch, as the two different fluids are not interchangeable. Always use good, clean, quality fluid that conforms to what is specified on the brake components. ♦ Be sure all fittings and seats are clean before making connections.
The pressure from either side of the motor can release the brake. This feature enables the winch to pull in as well as power out. The brake is not direction sensitive. The maximum pressure rating is 3000-psi including spikes or surges. WARNING - SURGE PRESSURE IN EXCESS OF 3000 PSI GENERATED BY PUMP SURGE OR RAPID OPENING OR CLOSING OF THE CONTROL VALVE WILL CAUSE THE PISTON TO FRACTURE. The O-rings (Buna "N" material) in the piston are only compatible with petroleum-based fluid.
Likewise, when the winch is not in operation, attach the winch line quick hook to a solid member on the tail shelf and slowly take up the slack. This will best maintain the rope under a slight amount of tension until its next use and will prevent the rope from unwinding or "clock-springing." 3.07 WINCH DRUM DIRECTION OF ROTATION - Depending upon customer specifications, the wire rope will either be over-wound or underwound.
♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ Check the hydraulic system reservoir to make certain that it is filled to the correct level with the proper grade of oil. Make certain that the reservoir shut-off valve is OPEN. Check the hydraulic system for the correct pressure and flow. Check all winch and winch accessory gear housings for the correct oil level and grade. See Section 6.02 LUBRICATION. Engage the hydraulic pump drive and allow the oil to circulate and warm up for a few minutes before operating the winch.
If the winch has not been used for an extended period of time, inspect the interiors of the drive housing and final drive housing for water deposits and rust due to the elements or condensation. Particular attention should be given to any damaged bearings, seals or gaskets. The oil should be checked for contamination, abrasive foreign particles and lubrication qualities. As required, oil should be added or completely drained and filled.
Grease fittings and oil cups on the levelwind should be serviced every seventy-five (75) hours of operation. Apply a coat of engine oil to all chain drives every seventy-five (75) hours of operation. The lubricant should be applied on the inside surface of the roller or silent chain by means of a spray or brush. When the winch is not in operation, pass the winch line through the tail shelf sheave and hook the pulling eye onto a fixed section of the chassis. Slowly take up the slack.
