Excavator Troubleshooting Methods That Novices Need To Know

In this article, let's discuss the faults and solutions that often occur in excavators for beginners' reference.

First of all, the sound of the cab is not normal. Check if the silicone oil damper at the four corners of the cab is loose. When the damper screw is loose, the cab will generate abnormal noise, especially when the engine is running at high speed, the cab and the surrounding area will emit abnormal noise. The glass is particularly noticeable, so we need to tighten the four screws under the cab.

The cab has a slight vibration when there is a click in the rotating part. This vibration is caused by impurities between the gear and the gear or after the gear is broken. When rotating to a fixed position, if there is abnormal noise, the rotary motor appears. When vibrating, check the gear oil and lubricate the butter with impurities or nails.

The hydraulic pump is abnormally vibrating. First, we need to check if the hydraulic oil is insufficient. Then, the professional hydraulic service technician checks whether the pressure is normal, whether the engine power is matched, whether the hydraulic pump output pipe is shaking, whether the regulator is issued, and the safety should be checked. Check if the solenoid valve switch is in place, check the hydraulic oil and return oil filter for metal powder, and judge whether the plunger is worn. Shake the pilot tubing and check that the pilot filter and filter fittings are clogged.

If the engine is vibrating, check the four foot pads of the engine for damage. If it is damaged, replace it with a new one. This will ensure the balance of the engine.
