The Stellar 11670 Seal Kit is a genuine OEM hydraulic-cylinder repair kit designed for Stellar cylinder D0771. It is specified for a hydraulic cylinder with a 4.50-inch bore and 16.00-inch stroke.
If the cylinder leaks hydraulic fluid, drifts under load, loses pressure, or operates inconsistently, the Stellar 11670 provides the replacement sealing components required to rebuild the cylinder. Installing new seals can restore hydraulic performance without replacing the complete cylinder when its structural components remain serviceable.
What This Part Is Used For
The Stellar 11670 seal kit replaces worn internal seals in hydraulic cylinder D0771. The seals help contain hydraulic fluid, maintain pressure, and prevent internal bypass during cylinder extension and retraction.
