Caterpillar 2818261 Exhaust Manifold Sleeve

The 2818261 exhaust manifold sleeve is a critical sealing component designed for Caterpillar heavy-duty diesel engines. It installs into the cylinder head exhaust ports to provide a secure, leak-resistant connection between the exhaust manifold and the engine block. Constructed from high-temperature heat-resistant alloy, the flanged sleeve withstands extreme thermal cycling and vibration inherent in heavy equipment operation. This sleeve assembly serves as a direct replacement for OEM part numbers 281-8261, 262-9103, 1016706, 1953187, and 1887775. It is engineered to meet OEM specifications for durability and precise fitment, eliminating exhaust leaks that degrade engine performance and increase emissions. The component is essential for maintaining exhaust system integrity during engine overhaul or manifold replacement.
