The Caterpillar 345D excavator typically uses two pilot pumps.
K3V112:This is the main pilot pump for the excavator. It provides hydraulic fluid to the pilot control system, which is responsible for operating 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 is a secondary pilot pump that provides backup power to the pilot control system in case the main pilot pump (K3V112) fails. The K3V63 is also a gear pump, sharing similar characteristics with the K3V112.
Here's a summary of the pilot pumps used in the Caterpillar 345D 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.
It's crucial to maintain the pilot pumps properly to ensure the smooth and reliable operation of the excavator's hydraulic system. This includes regular fluid changes, filter replacements, and inspections for leaks or damage.
If you have any further questions about the pilot pumps in the Caterpillar 345D excavator or need assistance with troubleshooting or maintenance, it's recommended to consult the excavator's user manual or contact a hydraulics specialist.
