Hazard
In the travel reduction gearbox of the shovel loader, some units have improper machining precision in the reduction gearbox case on the hydraulic motor mounting side, causing misalignment between the drive shaft of the hydraulic motor and the gear center of the reduction gearbox. Continued operation in this condition may cause wear on the hydraulic motor drive shaft (spline section), and in worst cases, the drive shaft may be worn through, resulting in loss of travel capability.

ショベルローダの走行減速機において、油圧モータ取付側減速機ケースの加工精度が不適切なため、油圧モータの駆動軸と当該減速機のギアの中心がずれているものがある。そのため、そのままの状態で使用を続けると油圧モータの駆動軸（スプライン部分）が摩耗し、最悪の場合、駆動軸が摩滅し、走行不能となるおそれがある。
Remedy
Replace the affected reduction gearbox case with a serviceable part on all vehicles.
