How to repair a small loader that has encountered a driving fault

As the service life of small loaders increases, their working performance tends to decline, much like a person aging. They are prone to various malfunctions, which can affect normal work and construction progress. When malfunctions occur, maintenance work becomes essential. This requires repair personnel to have a proficient understanding of the causes and repair methods of various malfunctions.

If the loader fails to travel normally, or travels sluggishly or not at all in a certain gear, where should we start with the maintenance? Laizhou Loader provides you with the following troubleshooting and maintenance methods:

When such phenomena occur, we must first carefully analyze the causes of the malfunction. If a certain gear is experiencing weak or no movement, we can rule out issues with the torque converter, travel pump, pressure reducing valve, and other common oil circuits and components for all gears. At this point, we need to carefully observe the transmission oil circuit for problems, such as internal oil blockage or insufficient oil. If these are not the issues, we need to check whether there are foreign objects in the transmission oil filter. If metal foreign objects are found, it usually indicates damage to internal transmission parts. Generally, at this time, the loader cannot move normally, but the power arm can be used normally. For such malfunctions, we need to inspect the transmission oil circuit.

Assuming there are no issues with the oil circuit and transmission, it is also necessary to inspect the wear condition of the bearing cover or nylon ring. If the wear is severe, it can affect the sealing performance. The oil supplied to the clutch piston chamber leaks significantly from the worn area, resulting in a decrease in oil pressure.

To ensure the normal operation of the small loader, we recommend regular inspections and maintenance, timely replacement of damaged parts, and regular inspection of the oil circuit and oil change. This will not only enable the loader to work stably but also extend its service life.
