Overview
| MLIT filing number | 1139860 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | February 20, 2017 |
| Manufacturer(s) | Isuzu |
| Component | Propeller Shaft |
| Production period | December 18, 2001 — December 27, 2005 |
| Vehicles affected | 27 units |
Defect
On vehicles modified to operate on rail tracks, the propeller shaft was assembled with a mounting angle exceeding the design specification due to inadequate design consideration during development. This subjects the propeller shaft to excessive load during operation, causing cracks to develop. Continued use can result in fracture of the shaft, and in the worst case, the vehicle may become inoperable.
Corrective action
On all vehicles, remove the caster plate and install the corrected part (flat plate). Also replace the propeller shaft with a conforming part.

状況
軌道上を走行できるように改造した車両のプロペラシャフトにおいて、開発時の設計が不適切なため、プロペラシャフトの取付角が改造基準の設計値を超えて組み付けられたものがある。そのため、走行時に過大な負荷がかかり、そのままの状態で使用を続けると、亀裂が生じて折損し、最悪の場合、走行不能となるおそれがある。
改善措置
全車両、キャスタープレートを取り外し、対策品（板状プレート）を取り付ける。また、プロペラシャフトを良品に交換する。
