3600 DieselOversized valve seat inserts are available for use in 3600 series diesel engines. The new inserts provide increased serviceability of the cylinder head. Caterpillar Reman cylinder heads may contain these valve seat inserts. See Table 1 and Table 2 for the available configurations of valve seat inserts.

Water cooled valve seat insertOversized machining of the bore for the valve seat insert in the cylinder head is required. Since the valve guides act as pilots for the tool that machines the bores,Caterpillar recommends installing new valve guides in the head before machining the bore for the insert. The bores for the valve seat inserts need to be machined to the dimensions that are listed in Table 3 and Table 4.
