Jerky controls, stiff joysticks, or loss of pilot-operated functions — a failing pilot pump is often the first sign your CAT excavator's hydraulic control circuit is under pressure. We supply premium-grade, direct-replacement gear-type pilot pumps and charge pumps engineered specifically for the CAT lineup.
Why Choose Our CAT Replacement Pilot Pumps?
- Direct Flange Mounting: Engineered to exact OEM dimensions to bolt directly onto the rear of your main piston pump assembly — no modifications, no adaptors.
- Fully Assembled and Tested: Every pilot pump arrives pre-assembled and factory pressure-tested, ready for rapid installation to minimise machine downtime.
- Seal Kits Available: If you only need to stop a leak between the main pump and pilot unit, we also stock the appropriate O-ring and seal kits.
The pilot pump is almost always physically attached to the rear of the main tandem pump assembly. We offer exact-fit units matching both CAT part numbers and original manufacturer specifications.
Provide our parts team with your CAT machine serial number or the stamped data code on your current pump housing, and we'll ship the exact replacement you need.
