The 707-98-22870 Arm Cylinder Seal Kit is designed for the arm hydraulic cylinder of selected Komatsu PC30MR-2 series excavators. The arm cylinder provides the hydraulic force required to control excavator arm movement during digging, lifting, loading, trenching and material handling operations.
Worn or damaged arm cylinder seals can result in hydraulic oil leakage, reduced digging or lifting 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 applications including construction, excavation, earthmoving, landscaping, utility work, trenching and material handling. Proper hydraulic cylinder inspection and correct seal installation are recommended to help prevent premature wear and maintain dependable excavator performance.
Typical Applications: Construction • Excavation • Earthmoving • Landscaping • Utility Work • Trenching • Material Handling
Common Symptoms of Worn Arm Cylinder Seals
- Hydraulic oil leakage from the arm cylinder
