322BL Hydraulic Pump for CAT Excavator spare parts 114‑0602 1140602 A8VO107LA OEM

Product Overview

The Caterpillar 322B L belongs to the respected B‑series generation — 22‑ton machines that earned a reputation for solid build quality and simple, dependable hydraulics, and many are still earning on sites long after their newer replacements arrived. At the centre of that hydraulic system sits the A8VO107LA pump, referenced by part numbers 114‑0602 and 1140602: a swashplate axial piston pump whose design heritage traces back to Rexroth engineering, favoured for its robust construction and predictable service life. On a machine of this age, pump wear does not announce itself suddenly. It arrives as a gradual softening — the boom lifts a fraction slower, the bucket curl loses some punch, the hydraulic oil runs a little warmer, and a deepening mechanical note from the pump compartment confirms that internal leakage is growing. For owners keeping a B‑series machine productive, choosing an OEM‑grade replacement matters, because looser tolerances on an already aging hydraulic system simply do not last. This OEM‑grade A8VO107LA is built to the original geometry and control settings, so a worn pump can be exchanged directly and the 322B L keeps working as it was engineered to.

Core Advantages

1. OEM‑grade tolerances for an aging hydraulic system
An older machine's valves and lines carry years of wear. A pump held to OEM tolerances compensates for that rather than amplifying it — the result is stable pressure and flow, not a short‑lived performance spike.

2. Proven A8VO107 design, rebuilt to original standards
The A8VO platform is known for rugged, long‑service construction. Our OEM‑grade reproduction honours that design with modern precision machining, keeping the strengths of the original while holding tighter finished tolerances.

3. Regulator calibration matched to the B‑series power curve
The pump's control follows the original mapping, so it loads the engine smoothly and delivers flow where the controls call for it. Digging stays powerful and travel keeps its pace, without the overheating that mismatched pumps cause.

4. Documented interchangeability for confident installation
Each unit is checked against the original mounting and part references (114‑0602 / 1140602) before dispatch, so the workshop receives a pump that fits on arrival — no surprises mid‑job.

5. A sensible repair choice for a long‑depreciated asset
A B‑series 322 has finished its depreciation years ago. OEM‑grade supply at a practical cost restores performance without the dealer exchange price tag, keeping these machines productive for their remaining working life.

Manufacturing & Quality Control
The OEM‑grade route follows controlled specifications: material certification, precision machining, heat treatment of wear surfaces and clean assembly. Each completed pump is bench‑tested for pressure, flow and running noise before release, and only passing units are packed. Full preservation treatment and shock‑absorbing export packing protect the assembly during long‑distance transport.

Frequently Asked Questions

Q1: How do I confirm this pump suits my 322B L?
A: Match the part numbers on your existing pump (114‑0602 / 1140602) and share your machine serial number. B‑series build variants can differ, so we verify before dispatch.

Q2: Can I reuse the existing regulator and piping?
A: Yes — the pump matches the original control interface and port layout, so existing piping and a serviceable regulator transfer directly. Damaged regulator parts are available separately.

Q3: What should I do to the hydraulic system when fitting the pump?
A: Renew the hydraulic oil and filters, flush contamination from the circuit, bleed the system after installation and run a no‑load warm‑up before returning to full digging work.

Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage from contaminated oil, wrong fluid, foreign objects in the circuit, overload operation or incorrect installation is excluded; please follow the Caterpillar service manual for commissioning.
