Arm cylinder slow to extend or rod seal weeping on your EC210B or EC360B? A worn 14588100 arm cylinder loses the piston seal integrity that maintains arm extension force, causing slow arm crowd speed under load. RITO supplies this heavy-duty replacement arm cylinder to restore full EC210B-series arm extension force and clean, seal-tight operation.

Rod chrome layer matches EC210B-series OEM specification for hardness and corrosion resistance, ensuring the arm cylinder seal achieves full service life without premature rod wear.

Bore honed to OEM surface finish for correct piston ring contact, maintaining low internal bypass even at maximum EC210B arm crowd pressure during trenching.

14588100 covers EC210B, EC240B, EC290B and EC360B arm cylinder specification across four Volvo excavator models.

Multi-layer piston seal provides correct sealing across the full arm cylinder pressure range including pressure spikes during hard ground crowd.

FAQ
Q: How do I check for internal bypass in the 14588100 arm cylinder on EC210B?
A: Hold the arm fully crowded against a hard stop and monitor for slow arm dump movement over 60 seconds with controls neutral. Any measurable arm dump movement under this test confirms internal piston bypass.
Q: Can I rebuild 14588100 with a seal kit instead of replacing the full cylinder?
A: Yes if the rod chrome and bore are within specification. Replace the full cylinder if the rod shows deep scoring or chrome delamination that would immediately damage the new piston seal.
Q: What bleeding procedure should I follow after fitting 14588100 on EC240B?
A: Cycle the arm slowly through full crowd and dump five times at low engine speed before applying full load to purge air and seat the piston seal.
Q: How to confirm 14588100 is correct for my EC210B?
A: Match part number 14588100 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.
