Maintenance Tips
Change hydraulic oil every 2,000 hours using ISO VG 46 grade for K3V series pumps
Inspect swash plate every 500 hours: maximum wear limit 0.05mm
Clean breather filters monthly to prevent cavitation in K5V pumps
Technical Support
Q: Why does K3V112DT show 2.5MPa pressure drop?
A: Check servo piston clearance (max 0.02mm) and compensator springs
Problem: K5V80DTP produces knocking noise
Solution: Adjust cylinder block tilt angle to 15°±0.5°
Issue: Oil leakage at shaft seal
Fix: Replace with HNBR material seals (code: SEAL-K3V-2024)
