Filing in context

The Starting system is the most frequently cited component category in this archive, appearing in 21 of its 4,890 filings. This filing is one of 80 Mitsubishi notifications from 2013 in this archive. For scale, 4,178 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 1 year and 1 month.

Defect

On medium-duty route buses, the rubber components used in the starter are made from an unsuitable material, and the flywheel ring gear has insufficient wear margin. Frequent engine starts by the idling stop-and-start system cause premature wear of the ring gear. Continued use leads to starter slippage and, in the worst case, prevents the engine from starting.

Corrective action

On all vehicles, replace the starter with the corrected part and inspect the flywheel ring gear for wear. If wear exceeds the service limit, replace the ring gear with a new unit.

状況

中型路線バスにおいて、スタータに使用されているゴム部品の材質が不適切であることおよびフライホイールリングギヤの摩耗に対する余裕が不足しているため、アイドリング・ストップ&スタート・システムによるエンジンの始動を頻繁に行うと、当該リングギヤが早期に摩耗するものがある。そのため、そのままの状態で使用を続けると、スタータの空転が発生し、最悪の場合、エンジンが始動不能となるおそれがある。

改善措置

①全車両、スタータを対策品に交換すると共にフライホイールリングギヤの摩耗状況を点検し、使用限度を超えていた場合は新品のフライホイールリングギヤに交換する。
