1154144 Manifold Fits Caterpillar Models

One New Aftermarket Replacement Exhaust Manifold for Caterpillar (Cat) 3116 and 3126 Engines

This aftermarket replacement exhaust manifold is a rear-section end piece for Caterpillar 3116 and 3126 diesel engines. It mounts to the cylinder head and collects exhaust gases from the end cylinders of the engine, directing them to the turbocharger and exhaust system. The 3116 and 3126 engine family uses a multi-piece exhaust manifold assembly; this part (115-4144) is the rear end section of that assembly. Common failure modes include warping and cracking from repeated heat cycling, resulting in exhaust leaks.
