Abstract
A pin assembly for a piston block of a hydraulic cylinder includes a pin that is axially engaged with the piston block. The pin assembly also includes a floating bush that is spaced apart from the pin to receive a sleeve therebetween. The floating bush is also configured to exhibit axial and radial play in its movement relative to the sleeve. The axial and radial play in the movement of the floating bush allows the floating bush to align with a cap port of the cylinder housing prior to entering the cap port of the cylinder housing.
