Hazard

In the power transmission device, the welding between the sheave and boss of the secondary sheave (fixed side) is inadequate, resulting in insufficient weld strength in some units. Depending on driving conditions, cracks may develop in the weld area. If operation continues in this state, the weld may separate in the worst case, causing loss of power transmission and rendering the vehicle inoperable.

動力伝達装置において、セカンダリシーブ(固定側)のシーブとボスの溶接が不適切なため、溶接部の強度が不足しているものがある。そのため、走行条件によって溶接部に亀裂が生じ、そのままの状態で使用を続けると、最悪の場合、溶接部がはがれ動力が伝達できず、走行不能となるおそれがある。

Remedy

Replace the secondary sheave with a corrective component on all vehicles.
