Securing the right 4009220 cylinder liner ensures that your Engine rebuild meets factory performance specs without the "original brand" price markup.
This is often caused by a failed liner O-ring or cavitation on the external wall of the 4009220 liner. When the liner surface erodes, coolant leaks into the crankcase. Replacing with our high-density replacement liner ensures a perfect seal.
Common symptoms include excessive blow-by, blue smoke from the exhaust, and loss of compression. For Cummins K19 engines, precise bore measurements are required during overhaul to determine if the 4009220 sleeve has reached its wear limit.
OEM-standard tri-metal structure: Our liners use a specific metallurgical blend that handles high-injection pressures. Trusted by repair shops & equipment fleets worldwide for heavy-duty maintenance cycles.
