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 6E-1279 / 6E1279.
Q: My 140G grader is experiencing hydraulic pressure drop or slow blade response. Is it time to rebuild or replace the 6E-1279 pump?
A: Slow blade movement or steering lag on 12G, 140G, or 160G graders usually indicates internal bypass wear. Instead of performing a high-risk and costly pump rebuild (piston pump rebuilding), replacing it with this ready-to-install aftermarket 6E1279 piston pump is a much faster and more reliable solution to restore full operating power.
Q: Does this pump come pre-lubricated or ready for direct installation?
A: Yes, the pump arrives ready for installation. However, to prevent premature wear of the precision internal pistons and valve plates, we highly recommend performing a complete hydraulic system flush and filling with clean CAT-certified hydraulic fluid during installation.
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 and proper operating conditions.
