RITO 14729457 Boom Cylinder EC210B EC240B EC290B EC360B Hydraulic Lift Piston Rod Arm Excavator Hydraulic Boom Cylinder

Boom losing lifting force or cylinder rod seeping oil on your EC210B or EC240B? A worn 14729457 boom cylinder allows internal bypass across the piston that weakens lift force, while rod seal wear causes external leakage that contaminates the cab and work area. RITO supplies this heavy-duty replacement boom cylinder to restore full EC210B-series lift capacity and clean operation.

Key Features & Advantages


OEM Chrome Rod Specification

Rod chrome layer thickness and adhesion match EC210B-series OEM specification, providing the hardness and corrosion resistance that determines boom cylinder seal service life.

Precision-Honed Bore

Bore honed to OEM surface finish and dimensional tolerance for correct piston seal contact and low internal bypass at full EC210B working pressure.

Multi-Model EC210B-EC360B Fit

14729457 covers EC210B, EC240B, EC290B and EC360B boom cylinder specification across four Volvo excavator models.

Multi-Layer Seal Assembly

Rod and piston seal assembly rated for EC210B maximum boom pressure, with buffer seals that protect the primary rod seal from pressure spikes during heavy lifts.



FAQ

Q: How do I tell if the 14729457 boom cylinder has internal bypass versus rod seal leakage?
A: External leakage is visible at the rod seal. Internal bypass causes slow boom drift when held stationary under load without visible external oil. Confirm by holding boom at mid-stroke and watching for downward drift over 60 seconds.

 

Q: Can I replace only the seal kit in the 14729457 cylinder?
A: If the rod chrome is undamaged and the bore is within specification, a seal kit repair is economical. Replace the full cylinder if the rod shows pitting, score marks or chrome delamination that would cut the new seals immediately.

 

Q: What bleeding procedure is needed after fitting 14729457?
A: Cycle the boom slowly through full extension and retraction five times at low engine speed before applying full load. This purges air and seats the seal assembly before high-pressure operation.

 

Q: How to confirm 14729457 is correct for my EC210B?
A: Match the existing boom cylinder part number 14729457 and confirm machine model is EC210B, EC240B, EC290B or EC360B. Provide machine serial number for cross-reference.

 

Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
