CAT Grease Valve Description
YNF16966 grease valve, matching Caterpillar part number 190-8609, is designed for use in the track adjuster system of CAT excavators. Also known as a grease nipple or track adjuster fitting, this component allows high-pressure grease to be injected into the adjuster cylinder, thereby tensioning the track to optimal specifications. Built from hardened steel with anti-corrosion treatment, it resists high pressure, impact, and vibration typically encountered in field environments. Ideal for OEM replacement or service kits for undercarriage maintenance.

Knowledge Base
Grease valves are small but critical parts of an excavator’s track tensioning system. They allow high-pressure grease to push a piston, tightening the track. A faulty or blocked valve can lead to track misalignment or slack, reducing equipment efficiency and increasing wear.
