2. Increased steering turns, insufficient steering torque

Causes:

2.1 Oil leak in the pipeline, damaged seals.

2.2 Internal leakage in the cylinder.

2.3 Worn steering gear rotor, reduced displacement.

2.4 Low steering valve pressure.

2.5 Severely worn steering pump.

Solution:

2.1 Replace seals, tighten joints.

2.2 Replace seals or the entire assembly.

2.3 Replace the rotor or steering gear assembly.

2.4 Adjust its pressure to the design pressure.

3.4 Adjust clearance.

4. Unstable steering with vibration

Causes:

4.1 Low oil level in the tank, air intake in the oil pump.

4.2 Cracks in the pipeline or damaged seals, allowing air to enter.

4.3 After prolonged parking, air separates from the oil and accumulates in the upper part of the steering cylinder.

4.3 Perform several full-turn maneuvers from left to right and right to left in place to expel air.

The Lutong LTS206H road roller is a 6-ton hydraulic single-drum vibratory roller with an attractive design, compact structure, low center of gravity, and smoother operation. It is suitable for

 compacting non-cohesive materials such as soil, gravel, and sand for roadbed and pavement compaction, and is also used for foundation compaction in railway, airport, port, dock, and dam projects.
