Defect
On certain trucks, an ra529 king pin release air valve was manufactured with the internal spool installed backwards. This results in the air option of the king pin release system being inoperable. To correct this situation, the vehicle's air lines were reversed rather than replacing the valve.
Safety risk
With the lines reversed, the king pin can be released without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
Remedy
Kenworth will inspect the king pin release system and suspect valve. If any vehicles have a nonconforming valve or incorrect plumbing, it will be replaced and re-plumbed. The recall began on november 29, 2006. Owners may contact kenworth at 1-425-828-5440.
