Hazard

In refrigerated vehicle left front chassis U-bolt washers, insufficient design consideration has resulted in some units having inadequate clearance between the hydrogen fuel tank and U-bolt washer. Consequently, vibration during operation causes repeated interference between the hydrogen fuel tank and U-bolt washer. Continued use in this condition may result in hydrogen fuel tank damage, and in the worst case, engine shutdown while driving.

冷蔵冷凍車の左最前方シャーシUボルト座金(以下、「Uボルト座金」)において、設計時の検討が不十分だったため、水素燃料タンクとUボルト座金の隙間が不足しているものがある。そのため、走行時の振動等により、水素燃料タンクとUボルト座金が繰り返し干渉し、そのままの状態で使用を続けると、水素燃料タンクが破損し、最悪の場合、走行中にエンジンが停止するおそれがある。

Remedy

Replace both upper and lower U-bolt washers with redesigned versions on all vehicles. If the hydrogen fuel tank is damaged, repair or replace the hydrogen fuel tank as necessary.
