Frequently Asked Questions
What is the function of the 9W1723 Pump G?
The 9W1723 Pump G is a hydraulic gear pump assembly that pressurizes and circulates hydraulic fluid throughout the machine’s hydraulic system. It converts mechanical power from the engine into hydraulic energy to operate steering, lift, and other hydraulic functions essential for heavy equipment performance.
How do I install the 9W1723 Pump G?
Here’s a general guide for proper installation:
- Park the machine on level ground, shut off the engine, and safely relieve all hydraulic pressure.
- Disconnect hydraulic lines, mounting bolts, and any sensors from the old pump.
- Carefully remove the old pump from its mounting.
- Clean the mounting surface and inspect fittings for wear or damage.
- Install the new 9W1723 Pump G, align it with the mounting holes, and torque fasteners to the specifications in your service manual.
- Reconnect hydraulic lines, refill the reservoir with the correct hydraulic fluid, and bleed the system if required.
- Start the machine and check for leaks and proper hydraulic performance.
Which machines or systems use the 9W1723 Pump G?
The 9W1723 Pump G is compatible with several Caterpillar track‑type tractors and dozers where this part number is specified. Typical models include D6H, D6H II, D6H XL, and D6H XR. It also fits machines powered by compatible engines like the 3306 series and others that require this specific hydraulic pump in their hydraulic circuits.

How often should a pump like the 9W1723 be inspected or replaced?
Hydraulic pumps should be inspected during routine hydraulic maintenance or if you notice performance issues. Look for fluid leaks, unusual noises, loss of pressure, or sluggish hydraulic action. If these signs are present, replacing the pump helps maintain proper system function and protects other hydraulic components.
