These grease valves are essential components of the automatic lubrication system, designed to dispense precise amounts of grease to critical wear points on the excavator. They ensure consistent lubrication, reducing friction and wear on components like pins and bushings, thereby extending their service life. A malfunctioning grease valve may fail to dispense lubricant, leading to increased wear, noise, and premature failure of lubricated components.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a faulty grease valve is the absence of grease at the intended lubrication point, which may be noticed during routine inspections. If left unaddressed, this will lead to increased friction and accelerated wear on the associated pins and bushings. The ultimate consequence is premature component failure, requiring costly repairs and significant downtime.
Ensure the grease lines are clean and free of debris before connecting them to the new valve to prevent internal contamination. Avoid overtightening the grease line fittings, as this can strip the threads or damage the valve body.
Inspect the entire automatic lubrication system, including the grease pump, reservoir, and all connected lines, for proper function and cleanliness.
