The 707-98-11180 Steering Cylinder Seal Kit is designed for the steering hydraulic cylinder of selected Komatsu motor graders, including the GD521A-1E and GD663A-2. The steering cylinder provides the hydraulic force required for controlled steering movement, supporting precise machine manoeuvrability and directional control during grading, road construction, road maintenance and earthmoving operations.
Worn or damaged steering cylinder seals can result in hydraulic oil leakage, reduced steering response, slow steering movement, steering 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 steering operation during demanding motor grader work.
This seal kit is suited to heavy-duty applications including road construction, road maintenance, earthmoving, grading, site preparation, quarrying and infrastructure development. Proper hydraulic cylinder inspection and correct seal installation are recommended to help prevent premature wear and maintain dependable motor grader performance.
Typical Applications: Road Construction • Road Maintenance • Earthmoving • Grading • Site Preparation • Quarrying • Infrastructure Development
Common Symptoms of Worn Steering Cylinder Seals
- Hydraulic oil leakage from the steering cylinder
