The defect
Lack of lubrication of the pins and the weakness of the material from which cylinder pins are made can develop into excessive pin wear. Such wear could cause the pins to shear, resulting in boom lift cylinder separating from the wrecker body.
The remedy
Installation of new pins made of stronger material and the installation of grease fittings which permit more convenient lubrication of the pin.
