Restore optimal crankcase pressure, eliminate blown seals, and protect your engine from harsh environmental contaminants with this premium Replacement Valve Breather (Part # 6666749). Engineered specifically for heavy-duty Bobcat skid steer loaders, compact track loaders, and excavators, this highly durable engine crankcase breather valve ensures perfectly calibrated ventilation, allowing harmful blow-by gases to escape while blocking job site dust, moisture, and debris from entering your engine's critical internal components.
A clogged, cracked, or heavily oil-soaked breather valve compromises your machine's operational reliability, leading to dangerous crankcase over-pressurization, sudden oil leaks from main seals, and sudden equipment deadlining on the dirt lot. Our aftermarket Bobcat valve breathers are precision-manufactured with heavy-duty synthetic housings and high-efficiency internal filtration media designed to withstand extreme engine bay temperatures, high vibration, and continuous-duty warehouse and construction cycling. We offer transparent pricing with fast, fully insured, FREE shipping directly to your repair facility.
