M5X180 200-3373 Swing Motor Assembly Overview
The M5X180 200-3373 Swing Motor Assembly manufactured by Tatan is an axial piston rotary hydraulic drive unit built in accordance with ISO fluid power standards and heavy construction machinery specifications. Engineered specifically for 36-ton class Caterpillar 336D, 336D L, 336D LN, and 336D2 excavators carrying heavy 2.4 m³ rock buckets, installing this complete M5X180 200-3373 Swing Motor Assembly unit eliminates superstructure drift on inclines, slow slewing acceleration, and mechanical parking brake slippage.
Constructed strictly according to Caterpillar OEM dimensional standards, this unit integrates high-strength alloy cylinder barrels, a pre-adjusted mechanical multi-disc parking brake pack, and dual anti-cavitation crossover relief valves. It provides a direct bolt-on interface with original CAT planetary swing reduction gearboxes without requiring line or wiring alterations.

M5X180 200-3373 Swing Motor Assembly OEM Diagnostic Guide
Use this technical diagnostic guide to identify rotation and braking failures on your Caterpillar 336D excavator:
| Slewing Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Turret creeps or drifts when swing joystick is released | Friction disc lining wear in the mechanical parking brake pack or excessive high-pressure bypass across the piston block. | Replace with a complete pre-tested M5X180 200-3373 Swing Motor Assembly. |
| 2. Weak swing acceleration and heavy shudder under load | Anti-shock crossover relief valve poppet erosion or spring fatigue failing to hold rated 31.5 MPa working pressure under heavy bucket loads. | Inspect pilot control signals, flush lines, or install a calibrated complete motor unit. |
| 3. Grinding noise and metal shavings in swing gear oil | Input pinion bearing failure or cracked planetary sun gear teeth inside the mating reduction gearbox. | Clean reduction gearbox sump thoroughly, flush gear oil, and install a fresh motor assembly. |
| 4. High hydraulic oil leakage from motor output shaft | Motor case-drain line backpressure restriction blowing out the high-pressure radial shaft oil seal into gearbox. | Clear case-drain return hose restrictions and replace with a brand-new sealed motor unit. |
