Illustration 2 g01039487 Sequence for tightening the setscrews for the three cylinder engine - Refer to the illustration 2 for three cylinder engines. Gradually loosen the setscrews in the reverse numerical order. This will help prevent distortion of the cylinder head.
- Remove the setscrews from the cylinder head.
Note: The cylinder head is heavy. To avoid injury, take care when the cylinder head is lifted. Also take care not to damage the machined surfaces of the cylinder head during lifting and lowering the cylinder head.
Note: Do not use a lever to separate the cylinder head from the cylinder block.
Show/hide tableNOTICE Place the cylinder head on a surface that will not scratch the face of the cylinder head.
- Use a suitable lifting device and carefully lift the cylinder head off the cylinder block.
