Typical example
5. Attach a suitable lifting device to cylinder head (3).
Support the weight of the cylinder head. The
weight of the cylinder head is approximately 30 kg
(66 lb).
Note: Use a spreader bar during the lifting operation
in order to distribute the weight of the cylinder head.
6. Use the lifting device to lift cylinder head (3)
carefully 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.
NOTICE
Place the cylinder head on a surface that will not
scratch the face of the cylinder head.
