Hydraulic Cylinder Rod Replacement Parts

There is no universal hydraulic cylinder rod size. Rod diameter, stroke, thread specification, eye dimensions, and bushing sizes are cylinder specific. McCann recommends strip-down inspection and measurement before ordering, using the machine make, model, serial number, cylinder function, and tag information to confirm the correct part.

A hydraulic cylinder commonly includes a barrel, piston, piston rod, gland, rod seal, piston seal, wiper, O-rings, backup rings, wear components, retaining hardware, and an eye or clevis connection. During a rod replacement, McCann also assesses the barrel bore, gland, bushings, pins, and the cylinder’s full seal kit.

Replacement is generally indicated when the rod has a measurable bend, scoring that catches a fingernail or runs through the seal travel, flaking or lifting chrome, widespread corrosion pitting, or damaged threads or end fittings. Light scratches, isolated small nicks, and superficial rust may be repairable after inspection if the chrome remains intact.

Availability varies by cylinder and manufacturer. McCann supplies OEM rods where the manufacturer offers them as service parts, and can quote quality aftermarket, replacement-cylinder, or remanufactured assembly options. CASE parts can be ordered through the CASE online parts store; other brands are quoted through the branch parts counter.

A strip-down inspection helps determine the correct route. A damaged rod can quickly destroy a new seal, while barrel, gland, piston, bushing, or contamination issues may require broader work. McCann can compare a replacement rod with a complete new cylinder and a remanufactured cylinder assembly before the repair path is selected.

Provide the machine make, model, serial number, cylinder function, cylinder tag information, and any available part details. Measurements should be taken during inspection because rod diameter, length, thread, eye or clevis dimensions, and bushing sizes vary. Photos may support an initial discussion, but McCann advises confirming condition and dimensions before ordering.
