New CAT 6Y6712 Pump Gp Caterpillar Aftermarket for CAT 3056, 3056E, 3114, 3116, 3126, C6.6, IT18F, IT24F, IT28G, 918F and more

The 6Y6712 Pump GP is a hydraulic gear pump assembly used to pressurize and circulate hydraulic fluid in heavy Caterpillar equipment. It converts engine power into hydraulic energy that drives steering, lift cylinders, and other hydraulic systems, helping ensure smooth operation of key machine functions.

Here’s a general guide for proper installation:

1. Park the machine on level ground, shut off the engine, and safely relieve hydraulic pressure.
2. Disconnect hydraulic lines and remove mounting bolts from the old pump.
3. Carefully remove the old pump assembly, noting hose routing and fittings.
4. Clean the mounting surface and inspect ports and fittings for wear or damage.
5. Install the new 6Y6712 Pump GP, align it with mounting holes, and secure bolts to the torque specs in your service manual.
6. Reconnect hydraulic lines, refill the reservoir with the correct fluid, and bleed the system as required.
7. Start the machine and check for leaks or proper hydraulic performance.

The 6Y6712 Pump GP is compatible with a range of Caterpillar equipment powered by engines such as 3056, 3056E, 3114, 3116, 3126, and C6.6. It’s also used on integrated tool carriers and wheel loaders like IT18F, IT24F, IT28G, 918F, 924F/G/H, and 928G/H series where this part number is specified. 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.

Yes, the 6Y6712 Pump GP is manufactured to meet or exceed OEM specifications for durability and performance. It undergoes strict quality checks to ensure a precise fit and reliable operation similar to the original Caterpillar part, helping maintain consistent hydraulic pressure and flow.

Hydraulic pumps should be inspected during routine maintenance or when you notice changes in hydraulic performance. Regular checks include: listening for unusual noises, checking for internal leakage, and watching for decreased responsiveness in steering or cylinder functions. Replace the pump if it shows signs of wear or failure to maintain proper system pressure.

Typical indicators include:

1. Reduced hydraulic performance — slow or weak cylinder movement
2. Unusual noises from the pump, such as whining, grinding, or knocking
3. Hydraulic fluid leaks around the pump body or fittings
4. Overheating in the hydraulic system

A quality hydraulic pump like the 6Y6712 ensures consistent delivery of hydraulic power to essential machine systems—such as steering, lift, and attachments. Using pumps that meet or exceed OEM specifications improves reliability, reduces the risk of hydraulic failure, and contributes to longer equipment life and uptime.
