This is the Terex shop manual for the TXC 175LC-1 hydraulic excavator, publication 023-00082E, for machines with serial number 30001 and up. The excavator runs a DB58TIS engine, and this 652 page manual is the full factory service reference for it.Sections cover safety, machine specifications, general maintenance and standard torques, the upper structure and cab, lower structure and undercarriage, engine and drive train, the complete hydraulic system, the electrical system, and the boom, arm, and bucket attachments. Pressure settings, torque charts, and troubleshooting procedures are included throughout.Independent mechanics and owners use this PDF to diagnose hydraulic power loss, set relief and pilot pressures, service the travel and swing motors, adjust track tension, and rebuild the main control valve. It is the same procedure set a Terex dealer technician would follow.

Terex TXC 175LC-1 Common Problems This Manual Covers
Hydraulic power fades after warmup
The machine works for a while, then goes weak or slow once the oil heats up. The hydraulics section covers system troubleshooting, testing, and adjustment for causes like a sticking relief valve, internal pump leakage, or a bad supply hose O-ring.
Manual Section: HydraulicsExcavator pulls to one side
A machine that will not travel straight often has internal leakage in a travel motor or a worn undercarriage. This section covers track tension, rollers, and the track adjusting cylinder.
Manual Section: Lower Structure and ChassisHard starting or no crank
Cranking problems trace to the battery, starter, charging, or wiring. The electrical section covers the starting circuit, preheating, charging, and the monitoring system.
Manual Section: Electrical SystemCab air conditioner not cooling
Weak or no cold air points to the refrigerant circuit. The engine and drive train section covers air-conditioner troubleshooting, refrigerant circulation, and system repairs.
Manual Section: Engine and Drive TrainWorn or loose bucket teeth
Digging performance drops as the teeth round off. The attachments section covers bucket tooth inspection and replacement along with front attachment pin specifications.
Manual Section: AttachmentsSwing bearing play or noise
Slop or noise when the house rotates signals swing bearing wear. The upper structure section covers swing bearing maintenance along with cab and counterweight removal.
