Bucket crowd force weak or cylinder rod leaking on your ZX200? A worn 9169806 bucket cylinder allows internal piston bypass to cut crowd force below what the machine needs for hard material penetration, while rod seal wear causes external leakage that contaminates the work area. RITO supplies this heavy-duty replacement bucket cylinder to restore full ZX200-series bucket crowd force and clean seal operation.
Item NO.:
9169806 / PG200115G9169806 Hydraulic Bucket Cylinder Assembly for Hitachi ZX200, ZX200-3, ZX210 excavators. Heavy-duty double-acting bucket cylinder with chrome-plated precision rod and a honed bore produced to OEM specification. Piston seal integrity and rod chrome finish are matched to the ZX200-class bucket duty cycle so the new cylinder restores original crowd force and cycle time from installation.

Rod chrome layer thickness and adhesion matched to ZX200-series OEM specification, providing the hardness and corrosion resistance that determine bucket cylinder seal service life.
Bore honed to OEM surface finish and tolerance for correct piston seal contact and low internal bypass at full ZX200 bucket pressure.
9169806 covers the bucket cylinder specification across the listed Hitachi ZX200-class models, keeping fleets on one interchangeable replacement.
Rod and piston seal assembly rated for ZX200 maximum bucket pressure, with buffer seals that protect the primary rod seal from pressure spikes during hard digging.
FAQ
Q: How do I tell if the 9169806 bucket cylinder has internal bypass or rod seal leakage?
A: External leakage shows at the rod seal. Internal bypass makes the bucket crowd slowly under load without visible external oil. Stall the bucket against a load and watch for slow drift over 60 seconds.
Q: Can I replace only the seal kit in the 9169806 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 9169806?
A: Cycle the bucket 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 9169806 is correct for my ZX200?
A: Match the existing cylinder part number against 9169806 and confirm the machine model is one of: ZX200, ZX200-3, ZX210. Provide the machine serial number for cross-reference confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
