Hydraulic fluid is from a hydraulic pump to a tool connected to respective first and second ends of a wellbore linear actuator. The actuator has a double acting cylinder with a cylinder head, a cylinder cap opposite the cylinder head, a piston head, and a piston rod. The piston head separates the cylinder into a first chamber and a second chamber, and the piston rod extends out of the second chamber through the cylinder cap. The double acting cylinder has first and second ends, and the double acting cylinder further includes a feed fluid passage between the first and second ends. The feed fluid passage includes a first fluid line through the piston head and the piston rod, the first chamber, and a second fluid line through the cylinder head.
