One New Aftermarket Replacement Precombustion Chamber Assembly Fits Caterpillar (Fits CAT) D-Series Engines
This aftermarket replacement precombustion chamber assembly Fits Caterpillar (Fits CAT) D375, D386, and D397 industrial and marine diesel engines. The precombustion chamber is a critical engine component seated in the cylinder head where fuel ignition and initial combustion begin. Over time, precombustion chambers can rust through from the water jacket side or crack under extreme compression forces and temperatures, allowing coolant to enter the combustion chamber -- replacement restores proper engine sealing and combustion performance.
