Filing in context
The Differential is the most frequently cited component category in this archive, appearing in 33 of its 4,890 filings. This filing is one of 47 Mitsubishi notifications from 2016 in this archive. For scale, 3,370 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 10 months.
Defect
On rear dual-axle heavy-duty tractors, the socket geometry of the torque wrench used to tighten the differential ring gear mounting bolts is incorrect, resulting in insufficient tightening torque on some units. Continued use allows the bolts to loosen and, in the worst case, the bolts may back out completely, causing differential damage and rendering the vehicle inoperable.
Corrective action
On all vehicles, tighten the ring gear mounting bolts to the specified torque.

状況
後２軸式の大型トラクタにおいて、ディファレンシャルのリングギヤを固定するボルトの締付作業を行う際、ボルト締付機のソケット形状が不適切なため、締付トルクが不足しているものがある。そのため、そのままの状態で使用を続けると、ボルトが緩み、最悪の場合、ボルトが抜け、ディファレンシャルが破損して走行不能になるおそれがある。
改善措置
全車両、リングギヤの固定ボルトを規定トルクで締付ける。
