Filing in context
The Propeller Shaft is the most frequently cited component category in this archive, appearing in 52 of its 4,890 filings. This filing is one of 37 Isuzu notifications from 2017 in this archive. For scale, 4,338 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 4 years.
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。
