Replacement Hydraulic Pumps for Heavy Equipment

Explore replacement hydraulic pumps at Fab Heavy Parts for selected excavators, tractors, wheel loaders, forklifts, backhoe loaders, and other equipment. This hydraulic pump collection includes hydraulic pump assemblies, gear pump configurations, and selected hydraulic pump repair components for different machinery applications.

Hydraulic pumps supply fluid flow to hydraulic systems that operate equipment functions such as lifting, steering, and attachment movement. Because pump designs and system requirements vary between machines, choosing a replacement requires more than matching the equipment manufacturer.

Hydraulic Pump Assemblies and Repair Components

Our hydraulic pump collection includes several hydraulic pump options for different maintenance needs:

  • Hydraulic pump assemblies: Replacement pumps listed for selected tractors, excavators, loaders, and forklifts.

  • Hydraulic gear pumps: Gear-type configurations, including selected tandem and double-section pumps.

  • Pump repair kits: Application-specific components for rebuilding certain hydraulic pump models.

  • Internal pump components: Selected replacement parts, including hydraulic pump pistons.

Complete pumps and repair components serve different purposes. Check each hydraulic pump listing to confirm the supplied components before ordering.

For more specialized options, explore our gear pump collection or main pump seal kits.

Hydraulic Pumps for Tractors, Excavators, and Loaders

The hydraulic pump collection includes replacement pumps listed for selected Kubota, John Deere, Caterpillar, Komatsu, Volvo, New Holland, JCB, Toyota, and other equipment applications.

Examples include hydraulic pump 6C200-37305 for selected Kubota B-series tractors, LVA12934 for John Deere 4120, 4320, 4520, and 4720 tractors, and 11703709 for Volvo L70B and L70C wheel loaders.

Others include hydraulic pump 87743513 / 87362337 for selected New Holland backhoe loaders and pump 67120-U3500-71 for specified Toyota forklift applications.

These are individual catalog-listed applications. Similar machines may require different pump configurations.

How to Select the Correct Hydraulic Pump

Start by identifying the part number of your existing hydraulic pump and your equipment's make, model, and serial number. Compare the replacement hydraulic pump listing with the existing pump assembly.

Depending on the pump type, important details may include shaft configuration, mounting pattern, rotation direction, hydraulic port arrangement, displacement, and control components.

If your existing pump's part number is missing, photographs of the pump identification plate, mounting flange, shaft, and hydraulic connections can help narrow down potential replacements.

Always confirm the required hydraulic system configuration before installing a replacement pump.

Frequently Asked Questions

How do I know which hydraulic pump fits my equipment?

Start by checking the part number and identification markings on your original hydraulic pump. Compare them with our replacement hydraulic pump listings and confirm your equipment make, model, and serial number. Depending on the pump, you may also need to verify the shaft type, mounting pattern, hydraulic connections, rotation direction, and operating specifications. We recommend confirming these details rather than selecting a replacement based on appearance or machine model alone.

What's the difference between a complete hydraulic pump and a pump repair kit?

A complete hydraulic pump is an assembled replacement unit, while a repair kit contains selected components intended to service a particular pump model. Our collection includes both types of products. The contents of repair kits vary, so check the product description to confirm which components are supplied. If you're unsure whether your existing pump can be repaired, we recommend assessing its condition before choosing between repair parts and a replacement assembly.

Can you help me find a replacement hydraulic pump if I don't know the original part number?

You can provide your equipment make, model, and serial number, along with clear photographs of the original pump. Images showing the identification plate, mounting flange, shaft, and hydraulic ports are especially helpful. If available, measurements or information from your equipment parts manual can also help us review possible replacements. Additional technical verification may be needed before compatibility can be confirmed.

What should I check before installing my replacement hydraulic pump?

Before installation, compare the received pump with the original assembly. Confirm the part number, mounting arrangement, shaft configuration, hydraulic connections, and any relevant control features. Inspect the pump for visible damage and verify that the supplied components match the part listing. Follow your equipment manufacturer's service instructions for hydraulic system cleanliness, installation, and any required setup or testing.

Will replacing my hydraulic pump fix slow or weak hydraulic operation?

A worn or damaged hydraulic pump can contribute to poor hydraulic performance, but similar symptoms may also result from control valves, fluid supply problems, system restrictions, or other hydraulic components. Replacing the pump may not resolve the issue if another fault remains. We recommend diagnosing the hydraulic system according to the equipment manufacturer's service information before deciding which component needs replacement.
