Leaking usually indicates the internal check ball or seal inside the 2S-5926 grease fitting has worn out or is clogged with debris. High-pressure injection over time can fatigue the spring. The solution is a direct replacement with a new 2S5926 fitting to restore the hydraulic seal and maintain proper track tension.

We recommend inspecting the grease valve every 500 operating hours or whenever you perform undercarriage cleaning. If the track appears loose and won't tighten despite pumping grease, the 2S5926 valve is the first component you should verify for functionality.
