TYPICAL HYDRAULIC CIRCUITS NOTE: The hydraulic circuits shown below are representative of typical HP35A winches with single and two-speed hy- draulic motors and brake valves. Options and accessory equipment may result in changes to the circuits shown. If there are any questions regarding the hydraulic circuit, contact the PACCAR Winch Division Product Support Department. - Page 11 WINCH BRAKE Low Speed High Torque Motor Case drain required if back pressure is greater than 100 psi.

Page 12: Wire Rope Installation
WIRE ROPE INSTALLATION Winches are rated at bare drum line pull, meaning the maximum load capability will be reached on the fi rst layer of wire rope. As the cable drum fi lls and adds layers of wire rope, the line pull will decrease (loss of leverage) as the line speed increases (larger circumference). -

Page 25: Service Precautions
Work in a clean, dust free area as cleanliness is of utmost importance when servicing hydraulic equipment. Inspect all replacements parts, prior to installation, to detect any damage which might have occurred in shipment. Use only genuine BRADEN replacement parts for optimum results. Never re-use expendable parts such as o-rings and oil seals. -
