WARNING
•
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle
pressure when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when
cleaning components. DO NOT direct compressed air against human skin. To prevent injury, user
must wear protective goggles or face shield. Make sure air stream is directed away from user and
other personnel in the area. Failure to follow this warning may result in injury to personnel.
•
Wear welding mask, gloves, and apron when welding or using cutting torch. Failure to wear
adequate protective clothing may result in injury to personnel.
2.
Using air-arc process, remove welds securing the kingpin (Figure 1, Item 1) upper surface and plug welds from kingpin
5-1/2-in.-square base. A 300-amp welder is required along with a “shop air” supply of 90 psi (621 kPa). Care must be
taken to minimize damage to bolster plate. Damage to kingpin being removed is of no consequence.
