CLAMP 5P8040 - Caterpillar

A regular program of preventive maintenance for your PACCAR winch will minimize the need for emergency servicing and promote long product life and trouble-free operation.The service intervals suggested in this manual will optimize component service life. The intervals may be gradually increased or decreased with experience of a particular lubricant and evaluation of your application.
Standard PTO Winch Case1. Oil Level
Check oil level at the beginning of each work shift with tractor and winch in level position. Oil must be visible in the upper half of the sight gauge. If an oil level plug is used in place of the sight gauge, the oil level should be at the bottom of the level plug hole. Add oil as required through the fill plug at the top of winch case.
LOW PTO Winch Case Lowered Winch Oil Level for Low-PTO Winches (PA56 for D6H, D6R and D6T)A small reduction in winch case oil level will reduce oil temperature in LOW PTO winches that are installed on tractors used in high cyclic, high travel speed applications. These applications include landfill compaction, road-building, coal plant waste compaction and mine reclamation.All LOW PTO PA56 winches built since November 2007, serial number 0704876 and later have a lowered oil level.To produce the lowered oil level, the traditional oil level sight glass on the right hand side of the winch case is removed and replaced with solid plug P/N 9S-8008 (-12 ORB flush plug). The clutch shaft left hand bearing carrier P/N 118-6951 is replaced by P/N 332-2447 that has a new port to accept a small oil level sight glass P/N 270-5244 (-8 ORB).The original oil volume was 16.5 US gal. or 66 qt. (63 l). The lowered oil level volume is 11.5 US gal. or 46 qt. (43.5 l).The winch pump will continue to draw oil from the sump at 45 degree forward or backward slope.2. Oil Change, Filter and Strainer Service
Under normal operating conditions, the oil and pressure circuit filter should be changed and suction strainer cleaned after the first 100-250 hours of operation, then every 1000 hours or six months, whichever occurs first, or when the filter bypass indicator light remains on after initial warm up. To drain oil, place tractor and winch in level position and remove drain plug located at lower right hand side of winch case. Drain oil into a suitable container and recycle or dispose of used oil in an environmentally responsible manner. Install plug securely after oil has been drained. After oil has drained, remove four suction strainer cover capscrews and cover. Remove suction strainer from winch case then remove metal band and magnetic rods from suction strainer. Thoroughly wash strainer in clean safety solvent and blow dry with compressed air, inspect wire mesh for damage or clogging with debris. Do not reuse a damaged suction strainer. Install magnetic rods onto suction strainer using metal band. Lubricate O-ring and install in groove on cover. Install strainer, spring and cover into winch case. If the suction strainer shield
