Excellent Customer service
A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you.
Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!

Product Questions
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. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.
Does the 9W1723 Pump G meet performance expectations?
Yes the 9W1723 Pump G is manufactured to meet or exceed OEM specifications for hydraulic performance and durability. Aftermarket versions are quality‑checked to ensure they match the fit and function of the original Caterpillar part, delivering reliable pressure and flow under heavy operating conditions.
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.
What are common signs that the 9W1723 Pump G needs replacement?
Typical indicators include:
- Reduced hydraulic performance (slow or weak actuator movement)
- Whining, grinding, or unusual noise from the pump area
- Hydraulic fluid leaks around the pump or connections
- Hydraulic system overheating during normal operation
Why is using a quality hydraulic pump like the 9W1723 important for equipment performance?
A quality hydraulic pump ensures consistent fluid delivery and pressure to critical systems like steering and implements. Using a part that meets or exceeds OEM standards improves reliability, reduces downtime due to part failure, and contributes to long‑term equipment durability especially under the demanding loads encountered in construction and earthmoving applications.
