2S8966 Gasket Kit-Chamber Fits Caterpillar Models

One New Aftermarket Replacement Precombustion Chamber Gasket Kit for Caterpillar (Cat) 3304 & 3306 Engines

This precombustion chamber gasket kit (also described as a precomb chamber gasket set) seals the precombustion chambers in Caterpillar 3304 and 3306 diesel engines. The precombustion chamber is the space where fuel is ignited and the combustion process begins; proper sealing at this interface is critical to compression, cold-start performance, and preventing coolant or combustion gas leaks. This kit contains multiple gaskets of varying thickness to allow correct rotational positioning of the chamber during installation, plus an O-ring chamber seal.
