Hazard
Due to inadequate clearance between the pin and bore hole that transmits rotation from the travel and braking hydraulic motors to the reducer, the bore hole shape deforms from wear and other causes. This creates excessive bending force on the bolts fastening the hydraulic motor and reducer, which may fracture. If use continues, excessive bending force causes the pin to fracture as well, potentially resulting in loss of travel capability and braking failure.

走行用及び制動用の油圧モータの回転を減速機に伝達するピンと穴部の隙間の不適切なため、磨耗等より当該穴部の形状が変形して、油圧モータと減速機を締結しているボルトに過大な曲げ力が生じ、当該ボルトが折損するものがある。そのため、そのまま使用を続けると、ピンに過大な曲げ力が生じて折損し、走行不能及び制動不能となるおそれがある。
Remedy
Replace the hydraulic motor and reducer assembly on all vehicles with corrected components.
