Frequently Asked Questions (FAQ)

Q: Is this piston pump a genuine Caterpillar part?

A: This is a premium-grade, OEM-compatible aftermarket replacement pump. It is engineered to exact CAT dimensional and technical standards, serving as a direct drop-in replacement for part number 167-1153 / 1671153.

Q: What causes slow bucket response or lost lifting power on CAT 966G or 972G loaders?

A: Internal pump wear on the pistons, barrel, or swashplate leads to pressure drops and fluid bypass under load. Installing a new 167-1153 piston pump eliminates pressure loss, restoring rapid cycle speeds and full breakout power.

Q: Does this pump come ready for direct installation?

A: The pump arrives ready for installation. We highly recommend standard system flushing, replacing hydraulic oil filters, and filling with fresh hydraulic oil before initial startup to protect internal precision components.

Q: What is covered under the 12-month warranty?

A: Our 12-month warranty fully covers all manufacturing defects, material failures, and workmanship issues under standard operating conditions.
