Find separate cylinder seal kit listings for CAT 320B excavator boom, arm and bucket positions. Each product page identifies the intended cylinder application and the rod and bore dimensions currently recorded in the FJKIT catalog.
Confirm the complete CAT 320B equipment model and actual hydraulic cylinder before ordering. The three kits may have different sizes and requirements. Compare the original cylinder part number, seal dimensions and component position rather than assuming the kits are interchangeable.
