Backhoe Hydraulic Cylinders

Start with the backhoe make, model, serial number and the cylinder position, such as boom, dipper, bucket, swing, stabiliser, lift or tilt. Confirm the existing part number where legible, mounting style, port orientation and retracted pin-to-pin length. Bore, rod diameter and stroke are position-specific and are not published by McCann, so confirm them against OEM data before ordering.

A universal lifespan is not stated because service life varies with duty cycle, side loading, contamination, rod damage, maintenance and the condition of pins and bushings. Leakage, drift, a scored or bent rod, reduced force and visible damage warrant inspection. A sound barrel and rod may support resealing, while scoring, pitting, bending or damaged mountings can require replacement.

Inspection should guide the decision. Resealing may be appropriate when the barrel and rod remain serviceable and the fault is a seal or wiper issue. Replacement is more appropriate when the rod is bent or scored, the barrel is damaged, the mounting eye is distorted or the cylinder has suffered severe contamination or dry running. Compare new OEM, remanufactured and aftermarket options with the rebuild route.

Provide the machine make, model and serial number, the cylinder position and the machine configuration. Useful details include extendahoe or standard dipper, two-wheel or four-wheel drive, pilot or mechanical controls, mounting style, port orientation and any legible part number. Backhoe cylinders can change across production runs, so ordering from a catalogue picture alone can result in an incorrect fit.

The range includes boom, dipper or crowd, bucket, swing, extendable dipper, stabiliser and loader-end lift and tilt cylinders. Availability and identification depend on the machine and position. McCann states that cylinders may be supplied as new OEM, remanufactured or quality aftermarket units, with CASE parts supported through its dealer channel and other makes sourced through its supplier network.

Often, a leaking cylinder can be assessed for resealing when the rod and barrel are serviceable. A scored or bent rod, damaged barrel, worn mounting or failed load-holding valve may require another repair route or complete replacement. Stabiliser drift should be treated as a safety issue because the cylinder and its valve can produce similar symptoms. Relieve stored hydraulic pressure and use proper lockout procedures before work.

CASE Construction Equipment is the backhoe loader line McCann carries, within a CASE range that also covers excavators, mini excavators, skid steer loaders, compact track loaders, backhoe loaders, wheel loaders, small articulated loaders, dozers, compact dozer loaders, mini track loaders, tractor loaders, rough-terrain forklifts, motor graders, compaction equipment, and attachments. Parts and service for other makes, including CAT, Deere, Komatsu, Bobcat and Kubota, run through the same counter.
