PUMP GP-HYD 10R9069 - Caterpillar

Hydraulic System
Make-up oil added to the hydraulic tank must mix with the oil already in the system. Use only petroleum products unless the system is equipped for use with special products.If the hydraulic oil becomes cloudy, water or air is entering the system. Water or air in the system will cause pump failure. Drain the fluid, retighten all hydraulic suction line clamps, purge and refill the system. Consult your Caterpillar dealer for purging instructions.
Air Inlet System
Check the precleaner daily for accumulation of dust and debris.Remove any dust and debris as needed. If the indicator shows red shortly after installing a cleaned primary element, install another clean element, or a new element.The primary element can be cleaned up to six times before replacement. The element, when cleaned, should be thoroughly checked for rips or tears in the filter material. Replace the primary element every year, even though it has not been cleaned six times.The secondary filter element should be replaced at the time the primary filter element is serviced for the third time.If the indicator shows red after installation of a clean primary element, or if the exhaust smoke is black, install a new secondary element.
Do not try to reuse the secondary element by cleaning it. Always use a new element.
Electrical System
When boost starting the machine, follow the instructions in the operation section of this guide to properly start the machine.When using an external power source to start the machine, turn the disconnect switch off and remove the key before attaching the booster cables.This machine has a 12 volt starting system. Use only equal voltage for boost starting. Use of a welder or higher voltage will damage the electrical system.
An emergency starting kit is available for starting from an external power source. It provides a permanent receptacle on the machine to plug in a booster cable.Two different cable assemblies are available for auxiliary starting. One for starting from an operating machine (with a receptacle) and one for starting from an auxiliary power pack. Your Caterpillar dealer can provide you with the correct cable assemblies for your operation.Engines installed without engine-to-frame ground straps can be damaged by electrical discharge.To prevent electrical discharge damage, check to make sure the machine's electrical system has an engine-to-frame ground strap. For machines which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Some machines have starter-to-frame ground straps. But, many of these starters are not electrically grounded to the engine. They have electrical insulation systems. For this reason, the starter-to-frame ground strap may not be an acceptable ground.Scheduled Oil Sampling (S-O-S)
Use Scheduled Oil Sampling (S-O-S) to monitor the condition and maintenance requirements of your equipment. Each oil sample should be taken when the oil is warm and well mixed, to ensure that the sample is representative of the oil in the compartment. When using the drain stream to obtain the oil sample, do not collect the sample from the first or final draining. Consult your Caterpillar
