This document provides instructions for removing and installing the cylinder head on Caterpillar 325, 325L, and 325LN excavators powered by a 3116 engine. The removal procedure involves removing several other components first, including the fuel filter base, governor, fuel control linkage, unit injectors, water temperature regulator housing, inlet manifold, and exhaust manifold. The cylinder head is then removed by detaching it from the cylinder block using bolts. The installation procedure provides detailed instructions for cleaning surfaces, installing a new cylinder head gasket, positioning the cylinder head, and tightening the bolts in a specific sequence and torque. Reinstalled components are also listed.
