Confirm Cylinder Fitment

Equipment-specific hydraulic cylinders should be matched by part number and application rather than bore and stroke alone. Mounting geometry, pin sizes, closed length, port position and hydraulic connections can vary between machines even when the basic cylinder dimensions are similar.

Before ordering, compare the existing cylinder part number and physical dimensions. For equipment applications, also verify the machine or attachment model and serial number when available.
