Illustration 6 g01340083
Sequence for tightening the bolts for the cylinder head
Gradually loosen bolts (14) in the reverse numerical order to the tightening sequence. Refer to the illustration 6. Note: Follow the correct sequence in order to help prevent distortion of the cylinder head.
Remove bolts (14) from cylinder head (15).
Illustration 7 g01340086
Typical example
Attach a suitable lifting device (16) to cylinder head (15). Support the weight of the cylinder head. The weight of the cylinder head is approximately 66 kg (145.5 lb). Note: A spreader bar must be used in order to distribute the weight of the cylinder head during the lifting operation.
Use suitable lifting device (16) to carefully lift cylinder head (15) off the cylinder block. Note: Do not use a lever to separate the cylinder head from the cylinder block. Take care not to damage the machined surfaces of the cylinder head during the removal procedure.
Place the cylinder head on a surface that will not scratch the face of the cylinder head.
