YANMAR 4TNV94/VOLVO D3.1 Deutz Engine Rebuild Kits For DH60/DH60-7 129086-25060

Common fault causes and solutions:

1. The reason for the "jump"

(1) Wear of variable speed transmission mechanism W4-60 excavator adopts mechanical shift transmission mechanism, which relies on the sliding gear sleeve to move axially on the fixed gear sleeve, and is connected with the driven gear of each gear. Engage to achieve a shift. During frequent gear shifts, the end faces of the above meshing gears can easily become tapered, which reduces meshing performance and causes "gear jumping".
(2) The performance of the self-locking mechanism decreases. In order to prevent the transmission from "jumping out", the excavator is installed in the box cover hole above the gear shift shaft of the transmission Ⅱ, Ⅲ, Ⅳ and Ⅴ, as well as in the gear shift fork of Ⅰ and reverse. The ball and spring act as a self-locking mechanism. When the spring elasticity of the positioning and self-locking function weakens or breaks, the self-locking performance of the self-locking mechanism decreases until it disappears, causing the transmission to "jump". Also, the transmission can "jump" if the grooves in the positioning ball or fork shaft are worn.
(3) Improper adjustment of the gear shift device The transmission of this type of excavator adopts the mechanical hand shift method. 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 nature of the excavator and the design of the machine itself, the sudden change of external load will also lead to its transmission "jump". When the road surface is uneven, the machine is driving downhill or the driving route is improper, and the external load suddenly changes, the sudden change of the load will act on the gear meshing gear of the transmission through the wheel and the drive shaft, so that the gear meshing gear is out of meshing due to the axial thrust, resulting in the transmission "jump".
(5) Improper operation method When the excavator is driving on the slope (especially downhill), if the operation is improper, it will also lead to the transmission "jump".

2. Preventive measures

(1) Operate in strict accordance with the operating rules and driving essentials, avoid "beating teeth" when shifting to reduce gear wear.
(2) Strictly implement the maintenance system and strengthen the maintenance of the shifting device. When the lever system of the gear shifting device is not connected properly, it should be adjusted in time to ensure the good performance of the gear shifting device.
(3) Pay attention to the maintenance of the self-locking mechanism, timely repair or replace the positioning steel ball, spring and fork shaft whose positioning effect is reduced or positioning efficiency is lost, so that the self-locking performance of the self-locking mechanism is in good condition.
(4) When assembling the transmission, it shall be operated in strict accordance with the operating procedures to ensure that all parts of the transmission are properly adjusted and tightened. In the large downhill, the driver should strictly abide by the essentials of downhill action, shall not violate the regulations.
