Claim 23:
24. A hydraulic system for controlling an engagement force of the roller of the muffler cap spinner apparatus of claim 18, the engagement force being exerted on the muffler end cap and the muffler shell, the roller being driven to engage the muffler end cap and the muffler shell by a hydraulic piston to secure the muffler end cap to the muffler shell, the hydraulic system comprising:
an oil tank housing oil;
a hydraulic pump fluidly coupled to the oil tank for drawing a flow of oil from the oil tank and directing the flow of the oil towards the hydraulic piston of the roller;
a control valve fluidly coupled to and disposed between the hydraulic pump and the hydraulic piston of the roller for controlling the flow of the oil from the hydraulic pump towards the hydraulic piston of the roller; and
a bypass line fluidly coupled to and disposed between the hydraulic pump and the control valve, the bypass line having a bypass valve for re-directing at least a portion of the flow of oil from the hydraulic pump away from the hydraulic piston of the roller to control a pressure of the flow of oil between the hydraulic pump and the hydraulic piston and to control the engagement force of the roller on the muffler end cap as the roller is driven to engage the muffler end cap by the hydraulic piston receiving the flow of oil.
