Overview
| MLIT filing number | 1141310 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 23, 2017 |
| Manufacturer(s) | Hino |
| Component | Wheel Bearing |
| Production period | November 2003 — May 19, 2017 |
| Vehicles affected | 39,687 units |
Defect
On heavy-duty low-floor four-axle trucks, the front hub bearing preload specification stated in the service manual is incorrect, causing the bearing preload to be set excessively high during maintenance. Additionally, if the outer bearing rollers or races are scratched during installation, the excessive preload may cause the roller surfaces to spall. This produces play in the outer bearing, and continued use may cause the brake to drag. In the worst case, a vehicle fire or wheel separation may occur.
Corrective action
On all vehicles, replace the outer bearing with a new unit and reassemble the bearing to the correct preload specification. In addition, notify vehicle owners and automotive service businesses of the proper front hub bearing maintenance procedure.

状況
大型トラックの低床４軸車において、整備解説書で指示したフロントハブベアリングの予圧の設定値が不適切なため、ベアリングの予圧が過大に設定されることがある。また、整備時にアウターベアリングを挿入する際、ベアリングのころ等を傷つけると、過大に設定された予圧により、ころの表面が剥離することがある。そのため、アウターベアリングにガタが生じ、そのままの状態で使用を続けると、ブレーキが引き摺り、最悪の場合、火災や脱輪に至るおそれがある。
改善措置
全車両、当該アウターベアリングを新品に交換し、適切な予圧の設定値で正確にベアリングを組付ける。併せて、使用者ならびに自動車整備事業者に向けて、適切なフロントハブベアリングの整備要領について啓発する。
