FAQ

Q: How do I confirm this pilot pump will fit my excavator?
A: First, locate the part number on your existing pilot pump (often stamped on the housing). Cross-reference it with the compatible models listed (SK135SR, SK135-8, SK140SR) and the K3V112DPP main pump designation. If your machine uses a different main pump, please verify the mounting flange and shaft dimensions match your old unit before purchase.

Q: What is the installation procedure for this pilot pump?
A: Installation is a direct bolt-on replacement. Ensure the hydraulic system is depressurized and clean. Remove the old pump, transfer any necessary fittings or couplings, and install the new unit with new O-rings or seals. After installation, prime the pump by filling it with clean hydraulic oil before starting the engine to prevent dry start damage.

Q: What maintenance is recommended for this pilot pump?
A: This is a sealed unit requiring no internal maintenance. To maximize its lifespan, ensure your hydraulic system’s oil is clean and at the correct viscosity. Regularly check and replace the hydraulic oil and return filter according to your machine’s service schedule. Contamination is the primary cause of pilot pump failure.
