Introduction

This Special Instruction contains the procedure to lubricate the replacement gear pumps for the machines that are listed. When you replace a gear pump from this list, complete the following procedure before starting the machine.

Safety

Show/hide table

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Note: Before working on the machine that is being serviced, follow all recommended safety procedures for machine preparation. Refer to the Operations and Maintenance Manual, Disassembly and Assembly, and Service Manuals for the machine that is being serviced.

Part Numbers by Model and Serial Number Prefix

The following table lists the part numbers for the pumps that require lubrication before start-up.

Start-up Procedure

Note: Always ensure that no foreign materials are allowed to enter the pump or the system that is being serviced during handling of the pump and during installation.

1. In normal temperature conditions, completely fill the pump with STP Oil Treatment and ensure that the pump rotates freely by hand. In cold weather, substitute system oil from the system that is being serviced.

   Use the filler plug opening if one exists. Use the inlet port if no plug exists. Refer to Illustrations 1 through 18 that are included in the "Illustrations" section that follows in order to determine the appropriate fill port.

2. Install the pump.

   ReferenceRefer to Disassembly and Assembly for the machine that is being serviced.

3. Check all related filters and pick up screens. Replace filters. Clean the screens.

4. Refer to Operation and Maintenance Manual, "Lubrication Viscosities and Refill Capacities" for all fluid capacities and filling procedures.

5. Run the machine at half throttle or higher at start-up. This will allow oil to be pulled more quickly from the sump.
