Hydraulic cylinder assembly system

A piston puller tool for installing a piston into a barrel of a hydraulic cylinder, comprising:

• a piston rod engagement member includes a base engagement member, a thrust retainer threaded projection, at least one threaded rod plug, said thrust retainer threaded projection extends from one end of said base engagement member, said at least one threaded rod plug extends from an opposing end of said base engagement member, wherein said at least one threaded rod plug is sized to be threaded into a piston rod of the hydraulic cylinder;
• a thrust bearing retainer includes a rod bore formed through one end, a bearing bore is formed into said thrust bearing retainer starting at an opposing end to receive a thrust bearing, a retainer thread is formed in said opposing end of said thrust bearing retainer to threadably receive said thrust retainer threaded projection;
• a draw rod having one end retained in said thrust bearing retainer;
• and
• a barrel end retainer is threadably retained on an opposing end of said draw rod, wherein said barrel end retainer is sized to receive an end of a barrel of the hydraulic cylinder.
