BOLT 3600798 - Caterpillar

Pump Functionally
The pump is composed of an electric motor attached to a shaft via a worm gear. This shaft drives both the single pumping element and the wiper blade. The pumping element is attached to the shaft via a cam and follower. No springs are present.

View of pumping element
The pump is a fixed output piston pump. The pump output is 0.12 cc (0.00732 cubic inch) per stroke/ pump rev. The pumping element is serviceable from the exterior of the pump. Follow instructions on pump label for proper assembly of replacement part.Note: Do not use brake cleaner on the lubrication pump, damage to the labeling can occur.

View of pumping element installation
The pumping element must be inserted at an angle and then pivoted down to ensure a proper seating of the follower on the cam.Relief Valve

View of relief valve
The pump is retrofitted with an over pressure relief valve. This limits the system pressure to 280 bar (4060 psi). Attached to the relief valve is a hose that reroutes grease back to tank in the event of system over pressure. Incorporated into the relief valve is a non-return valve that restricts flow back to tank. The main supply line is attached to the end of this valve.Reservoir Lid Sensor

View of lid
The reservoir lid contains a capacitance sensor and steel rod to aid in grease agitation during operation. The capacitance sensor is used to indicate a low reservoir.Note: Upon the event of grease falling below the sensor level, the greasing cycle pauses, and pump is shut off, and error alert is sent to display (active/logged). Upon refilling the reservoir, the system will automatically un-pause the greasing cycle and error code will be cleared.
