The 205-63-03121 Arm Cylinder Seal Kit is identified for the arm hydraulic cylinder of selected Komatsu PC200-6, PC200LC-6 and PC210-6 excavators. The arm hydraulic cylinder provides the hydraulic force required to control the excavator arm during digging, lifting, loading and material handling operations.
Worn or damaged arm cylinder seals can result in hydraulic oil leakage, reduced digging force, slow arm movement, arm drift, internal pressure bypass and loss of hydraulic efficiency. Replacing worn sealing components with the correct seal kit can help restore cylinder sealing performance, maintain hydraulic pressure and support dependable arm operation.
This seal kit is suited to demanding applications including construction, excavation, earthmoving, quarrying, mining and infrastructure development. Proper hydraulic cylinder inspection and correct seal installation are recommended to help prevent premature wear and maintain reliable excavator performance.
Typical Applications: Construction • Excavation • Earthmoving • Mining • Quarrying • Infrastructure Development • Material Handling
Common Symptoms of Worn Arm Cylinder Seals
- Hydraulic oil leakage from the arm cylinder
- Reduced arm digging or lifting force
- Slow arm movement
- Arm drift during operation
