VALVE GP 3T5815 - Caterpillar

A pressure hazard is present. Severe personal injury or death can result from removing hoses or fittings that are under pressure. Relieve the pressure in the system before you remove hoses or fittings.
Reference: Before any service work is performed on the lubrication system, refer to Special Instructions, REHS1394 or consult your Cat dealer.Autolube systems need to be adjusted before being put into use to ensure each joint gets the appropriate amount of grease. Different applications require frequency, volume, and proportioning adjustments from the recommended or factory settings.

Remove any buildup of grease. Check that each pin joint is receiving a fresh supply of grease. Reference: If a fresh supply of grease is not present, refer to Special Instructions, REHS1394 for system troubleshooting procedures.
Check the grease level at the top vent port of the reservoir. Reference: For filling procedures, refer to Operation and Maintenance Manual, "Automatic Lubrication Grease Tank - Fill".Settings of the Injectors for the Autolube System
The controller of the autolube system is preset from the factory. The lubrication is dispensed at 15 minute intervals, and all of the injectors are preset at the full flow setting. There may be an excessive buildup of grease around some of the joints. As a result, the grease reservoir may need filling more frequently. The injectors for selected joints can be adjusted in order to reduce the flow of grease without adversely affecting the life of the pin. The injectors are set by the factory at the full flow setting. This setting is equivalent to 5 turns open. When the injectors are adjusted, the injectors should first be closed. Then, the injectors should be opened by the number of specified turns. The recommended settings for the injectors at each pin location are listed in Table 1.
