The 707-99-59620 Arm Cylinder Seal Kit is designed for the arm hydraulic cylinder of selected Komatsu excavators, including the PC270, PC270LL, PC290 and PC308. The arm 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 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 reliable arm operation in demanding construction and earthmoving environments.
This seal kit is suited to heavy-duty 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 dependable machine performance.
Typical Applications: Construction • Earthmoving • Excavation • 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
