How can a fault be eliminated in a Komatsu?

During the rotation of the damper damper, a large amount of heat (Heat) is generated and transmitted to the hydraulic pump, causing the system to heat up. At this point, the fault can be eliminated by draining the shock absorber fluid to the standard oil level.

What causes a Komatsu water pump to heat up?

If the end face of the pump gear wears a lot or the tooth gap is large, the internal leakage increases, which will cause the pump to heat up and affect the normal operation of the main pump. The overflow valve pressure is too high or too low, which will cause the hydraulic system to heat up.
