description

The PC200‑8 swing motor adopts heavy‑duty axial plunger hydraulic structure paired with carburized‑quenched planetary reduction gears. Gear teeth are precision ground to improve surface hardness, wear resistance and impact resistance, adapting to frequent forward‑reverse swing impact of 20‑ton earth‑moving machines. Built‑in spring‑loaded wet multi‑disc wet brake realizes hydraulic release for swing action and mechanical locking after stop, effectively preventing upper‑structure sliding on slope working sites and improving operational safety. Optimized valve‑plate and piston‑shoe friction pair reduces fitting clearance, suppresses internal leakage and pressure decay under long‑time continuous heavy‑load cycles, restoring smooth and powerful swing performance consistent with original specification. Reinforced composite sealing kits resist hydraulic oil erosion and high‑temperature aging, lowering external oil leakage risk.

advantages

  • 1:1 OEM‑Equivalent Dimension, Lossless Field Swap: Mounting holes, output spline and hydraulic port layout strictly follow PC200‑8 original drawing standard. No casing machining, pipe cutting or welding required during overhaul, shortening equipment downtime.
  • Carburized‑Quenched Gear Train, Strong Anti‑Impact Performance: Precision‑ground planetary gear set improves surface hardness and fatigue resistance, coping with frequent swing impact of 20‑ton earth‑moving cycles and reducing gear pitting, abnormal noise and premature wear on aged machines.
  • Reliable Wet Multi‑Disc Brake, Prevent Upper‑Structure Drifting: Spring‑powered wet brake maintains stable holding torque after swing stops. Solves common drifting risk of aging PC200‑8 units on slope sites and improves construction safety.
  • Optimized Friction Pair, Reduce Internal Leakage & Swing Weakness: Improved valve‑plate and shoe matching accuracy suppresses internal leakage and pressure drop under long‑time high‑temperature heavy‑load operation. Restores original swing torque and mitigates slow‑speed and loaded‑swing weakness.
  • Reinforced Sealing System, Lower Oil‑Leakage Failures: High‑temperature‑resistant composite sealing components resist hydraulic‑oil corrosion and temperature‑cycle aging, cutting external‑leakage faults and lowering later‑stage maintenance frequency.
  • Full‑Set Factory Testing, Stable For Refurbished Units: Each PC200‑8 swing motor completes torque calibration, brake holding and high‑pressure leakage testing. Consistent performance for overhauled Komatsu PC200‑8 machines and enhances whole‑machine stability and residual value.

FAQ

  • Q1: Which machine is this swing motor suitable for?
  • A: Exclusively for Komatsu PC200‑8 20‑ton excavator, complete integrated swing motor assembly with reducer and wet parking brake, not interchangeable with other Komatsu series models.
  • Q2: What typical faults can PC200‑8 swing motor solve?
  • A: It repairs aging‑related swing faults: insufficient swing torque, slow slewing speed, swing jitter, brake slipping, upper‑structure drifting on slopes, high‑temperature internal leakage and external oil leakage.
  • Q3: Is casing or pipe modification required for installation?
  • A: No modification needed. 1:1 OEM‑matched mounting hole, spline and oil‑port layout support direct replacement following standard overhaul procedure.
  • Q4: Upper‑structure still drifts after swing‑motor replacement?
  • A: Apart from motor condition, inspect brake pilot pressure, brake relief‑valve setting, slewing‑bearing clearance and wear condition of main‑valve swing spool to eliminate hydraulic‑system and mechanical‑clearance anomalies.
  • Q5: Daily maintenance suggestions for PC200‑8 swing motor?
  • A: Keep hydraulic‑oil clean and replace filter elements on schedule. Avoid long‑time heavy‑impact frequent swing cycles. Regularly check motor housing for oil leakage and verify brake‑holding performance on slope conditions.
