Compatibility & Application Data
|
Application Sector |
Likely Equipment |
Symptoms Addressed by This Kit |
|---|---|---|
|
Site Grading & Earthmoving |
Komatsu Bulldozers (Model Specific) |
Inability to hold blade angle ("drift"), visible hydraulic oil leakage from the rod gland, slow or weak blade tilt response, oil pooling under the machine near the cylinder. |
|
Construction & Landscaping |
Dozer Blade Angle/Tilt Control |
Loss of precise grading control, "loose" or unresponsive blade feel, increased hydraulic fluid consumption, reduced machine efficiency. |
|
Heavy Equipment Repair |
Scheduled Overhauls & Leak Repair |
Restores factory sealing to ensure reliable blade control for precision work, prevents costly environmental fluid loss, and avoids the expense of complete cylinder replacement. |
