Sequence for tightening the bolts for the cylinder head
Gradually loosen bolts (6) in the reverse numerical order to the sequence that is shown in Illustration 6.Note: Follow the correct sequence to help prevent distortion of the cylinder head.
Remove bolts (6) from cylinder head (2).
Attach a suitable lifting device to cylinder head (2). Support the weight of the cylinder head. The weight of the cylinder head is approximately 50 kg (110 lb).Note: A spreader bar should be used to evenly distribute the weight of the cylinder head during the lifting operation.
