Rod chrome layer thickness and adhesion matched to XE215-series OEM specification, providing the hardness and corrosion resistance that determine arm cylinder seal service life.
Bore honed to OEM surface finish and tolerance for correct piston seal contact and low internal bypass at full XE215 crowd pressure.
803007159 covers the arm cylinder specification across the listed XCMG XE215-class models, keeping fleets on one interchangeable replacement.
Rod and piston seal assembly rated for XE215 maximum stick pressure, with buffer seals that protect the primary rod seal from pressure spikes during heavy digging.
FAQ
Q: How do I tell if the 803007159 arm cylinder has internal bypass or rod seal leakage?
A: External leakage shows at the rod seal. Internal bypass makes the arm crowd slowly under load without visible external oil. Stall the arm against a load and watch for slow drift over 60 seconds.
Q: Can I replace only the seal kit in the 803007159 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 803007159?
A: Cycle the arm 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 803007159 is correct for my XE215?
A: Match the existing cylinder part number against 803007159 and confirm the machine model is one of: XE215C. 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.
