Typical example
Inspect dowels (7) for damage. If necessary, replace the dowels in the cylinder block.
Install Tooling (A) to the cylinder block. Refer to Illustration 1.Note: During the following procedure, a new cylinder head gasket thickness must be calculated if the crankshaft, a connecting rod, or a piston has been replaced. Refer to Systems Operation, Testing, and Adjusting, Piston Height - Inspect.Note: During the following procedure, if the crankshaft, a connecting rod or a piston has not been replaced, obtain a new cylinder head gasket of the same part number as the gasket that was removed. The part number of the cylinder head gasket is marked at position (X).
Align cylinder head gasket (4) with Tooling (A) and with dowels (3). Install the cylinder head gasket onto the cylinder block.
