Visual & Functional Inspection
Weak Travel on One Side
  • Poor climbing performance, machine pulls to one side while other side works normally
  • Suspect: Internal leakage of travel motor, stuck two-speed valve, dragging brake or cross leakage inside swivel joint
Test Procedure: Swap left & right travel hydraulic lines
  • If fault moves with hoses → problem on main control valve / swivel joint
  • If fault stays on the same side → travel motor / final drive failure
One Side Track Does Not Move
  • No track movement when operating travel joystick
  • Possible causes: Parking brake fails to release (low pilot pressure, stuck brake piston); seized two-speed valve; severely worn valve plate / piston; broken planetary gears
Metal Grinding / Rattling Noise
  • Worse under load, metal chips found in gear oil
  • Suspect: Pitting, broken gear teeth or damaged bearings
Stop operation immediately once metal debris appears, otherwise the whole final drive will be destroyed.
Oil Leakage at Floating Seal
  • Gear oil leaks around sprocket hub
  • Causes: Worn floating seal, scratched sealing surface or blocked breather causing high internal pressure
  • Minor leak: Replace floating seal only. Replace assembly if sealing surface is deeply scored
Brake Slip on Inclines
  • Machine creeps downhill on inclined ground
  • Causes: Worn brake friction discs, fatigued brake springs or oil entering brake chamber
Slow Travel Speed & Speed Shift Failure
  • Failed high-speed shift, only low speed available
  • Causes: Stuck two-speed shift valve or insufficient pilot pressure
Pressure Test (Key Diagnosis)
  • Test working pressure of left and right travel circuits and compare readings
  • Measure drain oil flow from motor drain port. Excessive drain flow indicates worn piston / valve plate and heavy internal leakage
  • Check pilot pressure to confirm parking brake can release properly
Diagnostic Rule:
  • Low working pressure + large drain flow → damaged travel motor
  • Low pressure on both sides → fault on main pump or main control valve LS system, not travel motor
Gear Oil Sample Inspection
Take oil sample from final drive:
  • Fine metal powder: mild wear of bearings / gears
  • Large metal fragments: broken gear teeth, severe assembly damage
External Mechanical & Hydraulic Interference Check
  • Cross leakage of swivel joint seals
  • Blocked or leaking travel hoses
  • Mechanical jam of track, carrier rollers and track rollers
  • Worn spool or failed overload valve of travel section on main control valve
Quick Diagnosis Summary
Symptom Diagnosis
Single-side fault, fault remains after hose swap Travel motor / final drive fault
Single-side fault, fault moves after hose swap Main control valve / swivel joint
Both sides weak at the same time Main pump / main control valve system issue
Metal chips in gear oil Damaged planetary gears or bearings
