Filing in context

The Body is the most frequently cited component category in this archive, appearing in 108 of its 4,890 filings. This filing is one of 27 Mitsubishi notifications from 2019 in this archive. For scale, 2,521 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 2 years and 2 months.

Issue

On large tour buses, the tightening torque specification for the ball studs on the trunk and engine lid dampers was incorrect, causing some ball studs to be overtorqued during assembly. Repeated opening and closing of the lids loosens the ball studs, allowing the dampers to detach. In the worst case, the lid can no longer be held fully open and may fall.

Corrective action

On all vehicles, remove the lid damper ball studs, apply thread-locking compound to the threaded portion, and retighten to the correct torque. If correct torque cannot be achieved upon reinstallation, replace the component into which the ball stud is installed with a new part.

状況

大型観光バスにおいて、トランクおよびエンジンリッド用ダンパーのボールスタッドの締付けトルク指示が不適切なため、当該ボールスタッドが過大なトルクで締付けられたものがある。そのため、リッドの開閉を繰り返すことにより、ボールスタッドが緩んでダンパーが外れ、最悪の場合、当該リッドが全開状態を保持出来ず、落下するおそれがある。

改善措置

全車両、リッド用ダンパーのボールスタッドを取り外し、ネジ部に緩み防止剤を塗布して適正なトルクで再締め付けする。 なお、適正なトルクで再締め付けが出来ない場合は、ボールスタッドを取り付ける部品を新品に交換する。
