Excavator Replacement Parts

Excavator parts can be sourced directly through established heavy equipment dealerships like McCann. Equipment providers maintain multi-million dollar parts inventories, offer over-the-counter sales, provide remanufactured assemblies built to OEM specifications, and leverage extensive supplier networks to source hard-to-find components for multiple machinery brands.

Common accessories and attachments for excavators include digging buckets, ditch-cleaning buckets, hydraulic thumbs, rippers, plate compactors, and hydraulic breakers. These tools mount to the excavator stick or quick-coupler mechanism, allowing operators to transition between mass excavation, precise grading, concrete demolition, and specialized trenching operations.

An excavator ripper is a heavy-duty, pointed attachment designed to penetrate and fracture hard-packed earth, caliche, frozen ground, or solid rock. Positioned at the end of the arm in place of a bucket, the ripper focuses hydraulic breakout force onto a reinforced shank to break up difficult ground before general excavation.

The ideal excavator brand depends on specific jobsite requirements, application size, and dealer support. Trusted manufacturers like CASE, KOBELCO, and Takeuchi are renowned for hydraulic performance and reliability. Top fleets also operate CAT, Komatsu, and Deere excavators, relying on dependable parts availability to minimize operational downtime.

The main parts of an excavator include the diesel engine, hydraulic pump systems, slewing ring, counterweight, operator cab, track frames, boom, arm cylinder, stick, and bucket. Together, these primary systems provide the structural foundation, tractive effort, swing mobility, and digging breakout power required for earthmoving and site preparation.

The excavator arm structure primarily comprises the boom, the stick or dipper arm, and the bucket assembly. These structural steel components are connected by hardened pins and bushings, powered by hydraulic boom cylinders, stick cylinders, and bucket cylinders, and often linked to quick-couplers and hydraulic auxiliary piping.

McCann carries excavators from three lines. CASE Construction Equipment covers excavators and mini excavators. KOBELCO covers mini excavators, conventional excavators, short-rear-swing excavators, and specialty excavators for long-reach, demolition, and material-handling applications. Takeuchi covers mini excavators. Parts and service for other makes, including CAT, Deere, Komatsu, Bobcat and Kubota, run through the same counter.
