三菱 2Ga. Published by MLIT as 2103590 on 9 August 2007. Part: エンジン本体.

What the notice says 市場措置（改善対策届出番号３３３）の対策品において、クランクプーリをクランクシャフトに固定するテーパコーンの加工が不適切なため、テーパコーンの内径が過大なものがあり、また、クランクプーリの組立作業指示が不適切なため、クランクプーリが傾いた状態で組み付けられることがある。そのため、クランクプーリとテーパコーンの嵌合が不均一になり、クランクプーリに過大な応力が発生し亀裂が発生して、最悪の場合、クランクプーリが破損し補機ベルトが外れ、充電不良や冷却水温度の上昇及びハンドル操作が重くなるおそれがある。

What the ministry says is wrong

市場措置（改善対策届出番号３３３）の対策品において、クランクプーリをクランクシャフトに固定するテーパコーンの加工が不適切なため、テーパコーンの内径が過大なものがあり、また、クランクプーリの組立作業指示が不適切なため、クランクプーリが傾いた状態で組み付けられることがある。そのため、クランクプーリとテーパコーンの嵌合が不均一になり、クランクプーリに過大な応力が発生し亀裂が発生して、最悪の場合、クランクプーリが破損し補機ベルトが外れ、充電不良や冷却水温度の上昇及びハンドル操作が重くなるおそれがある。

What is to be done about it

全車両、クランクプーリ、テーパコーンを対策品と交換する。また、改善対策届出番号３３３による改善対策措置未実施の車両については、ダンパ、ダンパ取付ボルト、ウォーターポンプ一式を対策品と交換するとともに、クランクシャフトを点検し、損傷がある場合はクランクシャフトを良品と交換する。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered.

The Japanese register on this site

三菱 elsewhere in this register

三菱 is named on 887 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: エンジン本体

278 notices in this register name エンジン本体. A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Mitsubishi: 1,288 in the register, and 371 Japanese vehicle recall notifications filed in 2007.
