Frequently Asked Questions (FAQ)

Q: Does this 1262016 gear pump fit both D-series and C-series CAT excavators?

A: Yes, this gear pump is configured as a versatile replacement across specific 320C, 320D, and related mid-size chassis models. The mounting dimensions and shaft patterns line up perfectly across the listed machine generations.

Q: Why is flushing the system critical before installing this new pump?

A: When an old pump fails, it often sheds fine metal filings into the hydraulic line. If you do not completely flush the circuit and swap out filters, those residual metal particles can immediately score and ruin the new internal gears.

Q: What tests do these gear pumps undergo at the factory?

A: Every individual unit is subjected to rigorous dynamic flow, pressure sealing, and volumetric tolerance analysis on calibrated test benches to verify zero out-of-the-box defects.

Q: How long will it take to ship this pump internationally?

A: Orders for in-stock components are normally loaded and dispatched within 3–5 business days. We partner with express global air cargo handlers (DHL, FedEx, UPS) to achieve the fastest transit to your facility or yard.
