What This LiuGong Roller Service Manual Enables

This is a full workshop-level service manual, not a condensed owner’s guide. It gives you the exact procedures, torque values and specifications required to service the CLG614, CLG6114 and CLG616 rollers across every major system. The diesel engine chapter walks through the two mechanisms and five systems of the SC5D130G2B1 engine and its installation, including rotor-type oil pump installation, camshaft bushing pressing, crankshaft assembly, piston linkage installation, cylinder head assembly and valve clearance adjustment. The fuel system, lubrication system, cooling system, intake and exhaust system and start system are each covered with their flow routes and component functions.

The drive and brake chapter details the EQ4150G single-plate dry clutch, the CAGF5-90 three-forward two-reverse synchronous transmission, the air-over-hydraulic service brake and the internal expanding parking brake. Transmission disassembly is documented step by step: rear case removal, clutch release mechanism, top cover, upper cover, first shaft, reverse idler, output shaft and intermediate shaft assemblies, with part cleaning and part check procedures including bearing, gear, spline and thrust washer inspection criteria.

The hydraulic system chapter provides the full CLG6114 hydraulic schematic and covers the vibrating hydraulic circuit (vibration pump, motor and 4/3-way solenoid valve with balance valves) and the steering hydraulic circuit (steering pump, steering gear, steering cylinder and relief valve adjustment). The electrical chapter covers the vibration circuit, lighting, turn signals, instruments, indicators, sensors and air conditioning fault inspection, with multimeter measurement methods for DC voltage, ohm and buzzing positions.

The frame and vibratory drum chapters include front and rear frame disassembly, hydraulic oil tank and fuel tank removal, knuckle bearing and spider installation with clearance adjustment, vibratory drum removal, vibration housing disassembly and reassembly, eccentric shaft and bearing replacement, oil seal renewal, and bumping shell removal and installation. Cab and instrument panel disassembly, hood removal and adjustment are also documented.

Why This Manual Matters

Working on a vibratory roller without the correct torque values, clearances and assembly sequences risks damaging the drum bearings, the transmission synchronizers, the hydraulic pumps and motors, or the engine itself. This manual gives the technician the correct specifications: main bearing cover pre-tightening torque of 60 N·m plus 90±5°, connecting rod bolts at 40, 80 and 130 N·m in three stages, crankshaft rotational torque below 100 N·m with cylinder head removed, valve clearance of 0.30 mm intake and 0.60 mm exhaust, vibratory bearing and travelling bearing heating times, drive axle oil drain and refill torque of 60 N·m, wheel rim bolt torque of 810±70 N·m, and shock absorber compression of 2-3 mm.

It also gives the fault diagnosis logic for the diesel engine (won’t start, raised oil sump level, high oil consumption, abnormal oil pressure, high coolant temperature, insufficient power, abnormal exhaust color, abnormal noise), the transmission (gear engagement, synchronizer function), the hydraulic vibration system (abnormal frequency, abnormal vibration, slow vibration stop), the steering system (heavy steering when cold, hot, at idle or full speed) and the A/C (poor refrigeration, no air flow, compressor faults). That diagnostic reasoning turns a difficult repair into a guided troubleshooting process.
