Arm crowd slow or rod seal weeping on your SY335C? A worn 60011436 arm cylinder loses piston seal integrity and drops arm crowing force below what the machine needs for hard digging, while a scored rod seal leaks hydraulic oil across the cylinder head. RITO supplies this heavy-duty replacement arm cylinder to restore full SY305-series arm crowd force and clean, seal-tight operation.
Item NO.:

Rod and piston seal assembly rated for SY305 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 60011436 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 60011436 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 60011436?
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 60011436 is correct for my SY305?
A: Match the existing cylinder part number against 60011436 and confirm the machine model is one of: SY305C, SY335C, SY365C. Provide the machine serial number for cross-reference confirmation.
