Common fault causes and solutions:

1. The reason for "jumping"

(1) Wear of variable speed transmission mechanism W4-60 excavator adopts mechanical shift transmission mechanism, which relies on the sliding gear sleeve for axial movement on the fixed gear sleeve, and is connected with the driven gear of each gear. Engage to achieve a shift. In the process of frequent shifting, the tooth end face of the above meshing gear is easy to grind into a cone shape, which reduces the meshing performance and leads to "skipping teeth".

(2) The performance of the self-locking mechanism decreases. In order to prevent the transmission from "jumping", the excavator is installed in the box cover hole above the shift shaft of transmission Ⅱ, Ⅲ, Ⅳ and Ⅴ, and in the shift fork of Ⅰ and reverse. A steel ball and spring act as a self-locking function. When the elasticity of the spring that plays the role of positioning and self-locking is weakened or broken, the self-locking performance of the self-locking mechanism will decrease until it disappears, causing the transmission mechanism to "beat". At the same time, if the positioning steel ball or fork shaft groove wear, can also cause the transmission "jump."

(3) Improper adjustment of the gear shifting device The transmission of this type of excavator adopts the mechanical hand shift mode. The transmission can also "jump" if the shift lever, vertical shaft, horizontal shaft, and vertical setting screws are loosened.

(4) Sudden change of external load Due to the working nature of the excavator and the design of the machine itself, sudden change of external load will also cause its transmission "jump". When the road surface is uneven, mechanical downhill driving or improper driving route, the external load mutation, the load mutation will act on the meshing gear of the transmission through the wheel and the transmission shaft, so that the meshing gear is detached due to axial thrust, resulting in the transmission "jumping".

(5) Improper operation method When the excavator is driving on the slope (especially downhill), if the operation is improper, the transmission will also cause "beating".

2. Precautions

(1) Operate in strict accordance with the operating rules and driving essentials, and avoid "beating teeth" when shifting to reduce the wear of gear pairs.

(2) Strictly implement the maintenance system and strengthen the maintenance of the shift device. When the lever system of the gear shifter is not connected correctly, it should be adjusted in time to ensure the good performance of the gear shifter.

(3) Pay attention to the repair and maintenance of the self-locking mechanism, timely repair or replace the positioning steel ball, spring and fork shaft whose positioning effect reduces or loses the positioning efficiency, so that the self-locking performance is good. The self-locking mechanism is in good condition. .

(4) When assembling the transmission, the transmission shall be operated in strict accordance with the operating rules to ensure that all parts of the transmission are properly adjusted and fastened. In the large downhill, the driver should strictly abide by the essentials of downhill action, shall not violate the rules.
