Filing in context

The Drivetrain / Power Transmission is the most frequently cited component category in this archive, appearing in 6 of its 4,890 filings. This filing is one of 80 Mitsubishi notifications from 2013 in this archive. For scale, 3,334 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 3 years and 8 months.

Defect

The adapter connecting the engine flywheel to the transmission has a mounting flange surface that is not smooth, preventing the connecting bolts from achieving the required clamping force. Vibration during driving causes the bolts to loosen, increasing the stress they carry. Continued use in this condition can cause the bolts to fracture, leaving the adapter unsecured and interrupting power transmission. In the worst case, the vehicle becomes inoperable.

Corrective action

On all vehicles, replace the adapter and adapter mounting bolts with corrected parts. Apply molybdenum coating to the adapter mounting bolts to stabilize clamping force.

状況

エンジンフライホイルとトランスミッションの接続部品であるアダプタにおいて、フライホイルとアダプタを接続しているボルトの取付部座面が平滑でないため、必要な締結力が得られず走行時の振動によりボルトが緩み、ボルトに掛かる応力が増大する。そのままの状態で使用を続けた場合、ボルトが折損してアダプタが固定できなくなり動力伝達不能となるため、走行不能となるおそれがある。

改善措置

全車両、アダプタ及びアダプタ取付ボルトを対策品と交換する。アダプタ取付ボルトにモリブデンを塗布し、締結力の安定化を図る。
