Need the factory numbers for your Terex TXC 175LC-1 hydraulic excavator? This 652-page shop manual (OEM #023-00082E) runs the full TXC series, 175LC-1 through 470LC-1, from engine and drive train through upper structure, undercarriage, hydraulics, and electrical. The wiring diagrams trace every circuit from engine start through the monitoring system, while the hydraulic schematics cover pilot pressure routing and pump power control. It also packs step-by-step service procedures for every major assembly, torque tables (metric fasteners, U.S. fasteners, hose clamps, split flanges), exploded views for each system, and a troubleshooting section that handles hydraulic faults and air-conditioner diagnosis. Set the swing relief valve to 280 kg/cm² (3,980 psi), then confirm pilot pressure at 40±5 bar before buttoning up the pump. No more chasing specs across three PDFs. Everything is bookmarked: search any value, jump to any section, and get back to work.

Terex TXC 175LC-1 Common Problems This Manual Covers
Hydraulic power drops after about 30 minutes of use, with aerated oil and weak pump flow p. 236
Inspect the main supply hose O-rings for suction leaks. Measure pilot pressure at the pump on page 236 to confirm it holds 40 ±5 bar (580 ±73 psi). Torque worm drive hose clamps under 44 mm to 0.2 - 0.3 kg•m (20 - 30 in lb) as shown on page 89.
Manual Section: Troubleshooting - Hydraulic ProblemsExcavator does not travel straight and one side feels noticeably weaker during normal operation p. 467
Check the main control valve relief valves; page 467 specifies 330 kg/cm2 (4686 psi). Then inspect the travel motor for internal leakage and bleed any trapped air from the circuit.
Manual Section: Troubleshooting - Travel Control ValveSwing motor operates unevenly or lacks power when rotating a loaded bucket p. 233
Set the swing relief valve to 280 kg/cm2 (3,980 psi) per page 233. Inspect the swing gearbox for oil leaks, then drain the fluid and look it over for metal shavings.
Manual Section: Swing System TroubleshootingAir conditioning blows warm air or compressor cycles rapidly during hot weather operation p. 205
Recover the existing refrigerant and pull a vacuum on the system. Recharge with exactly 850 ±20 grams (30 ±0.7 oz.) of R134a gas using the specifications on page 205. Clean the cab air filters every 500 hours per page 193 to keep the evaporator from freezing.
Manual Section: Air-Conditioner TroubleshootingFrequently Asked Questions
How do I reset the monitoring system on a Terex TXC 175LC-1?
To reset operating hours for the filters and oils, open the "Operating Info" screen in the special menu, then press the Enter button ( , 3 on Figure 18) to reach the "Reset Hrs" screen. When "YES" is selected and the button is pressed, all operating hours are deleted; the system displays a resetting signal for 3 seconds and then returns to the previous menu.
How do I clear fault codes on a Terex TXC 175LC-1 excavator?
Clear fault codes from the "Failure Info" screen in the special menu. Select "Delete Fail Log" and press the "YES" button ( , 3 on Figure 18), and all memorized records of past failures are deleted. The panel shows a deletion signal for 3 seconds before returning to the previous menu.
What do the error codes mean on a Terex TXC 175LC-1?
Failure information codes are listed in tables. Code 82, "Communication Err!!," flags a fault between the e-EPOS controller and the instrument panel and clears on its own once corrected. Codes 01, 02, and 03, such as "EPPR v/v short" or "Press Up s/v short," signal a short circuit: the output current is cut off (0 mA), then you turn the start switch from "OFF" to "ON" after fixing the problem.
What are the hydraulic torque specs for a Terex TXC 175LC-1?
Hydraulic torque specs vary by component. Hose clamps in the hydraulic system call for 0.5 - 0.6 kg•m (40 - 50 in lb) on Worm Drive - Under 44 mm and Worm Drive - All "Ultra-Tite" types. Split-flange bolt torque runs from 2.1 - 2.5 kg•m (15 - 18 ft lb) at the 1/2" size up to 16.2 - 18.4 kg•m (117 - 133 ft lb) at the 3-1/2" size. Fit new O-rings and oil seals when rebuilding hydraulic assemblies, and tighten properly to keep them from leaking.

Document Quality
This document is a scanned PDF with an optical character recognition (OCR) layer, allowing you to search and copy text throughout. The text is generally crisp and readable, without significant blurriness or fading. However, many diagrams and technical illustrations appear to be raster images, which may become pixelated when zoomed, making some labels less clear. The pages are clean with no notable scan artifacts or skewed content, though there are numerous blank pages interspersed throughout the manual.
