Filing in context
The Propeller Shaft is the most frequently cited component category in this archive, appearing in 52 of its 4,890 filings. This filing is one of 17 UD Trucks notifications from 2024 in this archive. For scale, 3,438 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 5 months.
Defect
On large tractors (single rear axle), the yoke shaft and tube of the propeller shaft were welded using a non-standard procedure, resulting in insufficient weld penetration at the affected joint. Repeated stress during use causes cracks to form at the weld. Continued operation allows the cracks to progress to a complete fracture, separating the shaft and interrupting power transmission, leaving the vehicle inoperable.
Corrective action
On all vehicles, replace the propeller shaft with a conforming unit.

状況
大型トラクタ（後輪１軸）のプロペラシャフトにおいて、ヨークシャフトとチューブを正規と異なる操作で溶接したため、当該部位の溶接溶け込み量が不足しているものがある。そのため、使用過程で繰り返し応力を受けると溶接部に亀裂が発生し、そのまま使用を続けると、破断・分離し動力が伝わらなくなり走行不能に至るおそれがある。
改善措置
全車両、プロペラシャフトを良品と交換する。
