When using the loader for construction, the personnel must take the post with certificates. It is strictly prohibited for non professional personnel to operate. Pay attention to safety during operation and strictly follow the operation process. In addition, it is necessary to know some relevant problems in advance to avoid accidents. The following is a question for you from Jinan loader rental manufacturer: what is the problem that a certain gear of the loader is unable to move or cannot move, while the other gears are normal?
When it is unable to walk or moves slowly, the main drive shaft rotates rapidly and forcefully. When the engine speed is increased, the speed of the main drive shaft is obviously out of proportion with the front and rear drive shafts.
The transmission oil pressure of neutral gear and other gears is normal, and the pressure drops significantly after the gear is engaged.
1) The bearing cover or nylon ring is severely worn.
2) If the bearing cover or nylon ring is in good condition or slightly worn, confirm that the inner and outer sealing rings of the clutch are not well sealed.
Replace corresponding damaged parts, i.e. bearing cover or nylon ring, inner and outer sealing ring, and readjust the clearance between shaft sleeve and bearing cover.
If a certain gear is unable to move or cannot move, the problem of common oil paths and components of various gears such as torque converter, travel pump and pressure reducing valve can be eliminated. The fault can only occur in the oil path between the transmission control valve and the clutch piston of the gear.
After the weak parts such as bearing cover, nylon ring and inner and outer seal rings are worn, the oil supplied to the clutch piston cavity leaks from the worn parts in a large amount, thus causing the oil pressure to decrease. In neutral gear or other gears, the oil pressure display is normal because the oil does not flow through the worn parts.
