The new KPP143 heavy-duty king pin press from Ari-Hetra allows mechanics to work at a safe distance and reduces exertion associated with removing king pins using a hammer and punch or a manual press. According to the company, the KPP143 also reduces the potential of spindle or axle damage. The King Pin Press features an air assisted piston that moves the press into place and a hand pump that uses 143,000 lbs of compression force to remove the king pin.
