The Caterpillar 349D excavator, like its predecessor the 345D, typically utilizes two pilot pumps:
A K3V112: This serves as the main pilot pump, providing hydraulic fluid to the pilot control system that operates the main hydraulic control valves. The K3V112 is a gear pump, known for its reliability, low cost, and ability to deliver consistent flow at moderate pressures.
A K3V63: This acts as a secondary pilot pump, offering backup power to the pilot control system in case the primary pump (K3V112) fails. The K3V63 is also a gear pump, sharing similar characteristics with the K3V112.
Here's a table summarizing the pilot pumps used in the Caterpillar 349D excavator:
| Pump | Type | Function |
| K3V112 | Gear Pump | Main Pilot Pump |
| K3V63 | Gear Pump | Secondary Pilot Pump |
The specific part numbers for these pumps may vary depending on the exact configuration of the excavator.
The pilot pumps are typically located in the hydraulic oil tank of the excavator.
Proper maintenance of the pilot pumps is crucial for the smooth and reliable operation of the excavator's hydraulic system. This includes regular fluid changes, filter replacements, and inspections for leaks or damage.
