must be removed to carry out this
measurement.
N0TE:Make sure that the camshaft is to
specification.
N0TE:The bearing caps and journals should be
free from engine oil and dirt.
Position on a width of plastigage on the
bearing cap.
Insert the camshaft, without lubrication, into
the cylinder head.
Position
a plastigage strip, which should be
equal to the width of the bearing cap, on the
bearing journal.
2. Following the tightening specification, install
the camshaft bearing caps. Refer to the
corresponding Section 303-01.
3.
N0TE:Do not strike the bearing caps.
Remove the camshaft bearing caps, refer to
the corresponding Section 303-01.
'4. Using the Plastigage, read off the
measurement.
Compare the width of plastigage with the
plastigage scale.
