Overview
| MLIT filing number | 1131550 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | May 24, 2013 |
| Manufacturer(s) | Hino |
| Component | Other (power transmission) |
| Production period | November 29, 2003 — June 2011 |
| Vehicles affected | 4,217 units |
Defect
On large tractors equipped with a 12-speed transmission, the surface hardness of the flange coupling end face at the rear of the transmission is insufficient. Bearing creep causes the flange coupling end face to wear, allowing the flange coupling fastening bolts to loosen. Continued use in this condition allows the flange coupling to work free and, in the worst case, detach together with the propeller shaft.
Corrective action
Replace the flange coupling and the affected bolts with corrected parts on all vehicles, and replace the thrust washer and O-ring with new components.

状況
１２段式変速機を搭載した大型トラクタにおいて、変速機後端のフランジカップリング端面の表面硬度が不足しているため、ベアリングのクリープに伴いフランジカップリング端面が摩耗し、フランジカップリング締付けボルトが緩むものがある。そのため、そのままの状態で使用を続けると、フランジカップリングが抜け出し、最悪の場合、プロペラシャフトとともに脱落するおそれがある。
改善措置
全車両、フランジカップリングと当該ボルトを対策品に交換するとともに、スラストワッシャーとＯリングを新品に交換する。
