GENERAL PROCEDURES
Camshaft Bearing Journal Diameter
1. Determine the diameter of the camshaft
journals.
Using a micrometer measure the diameter
at
90 degrees intervals to determine if the
journals are out-of-round.
Measure at two different points on the journal
to determine if there is any tapering.
If the measurements are out of the specified
range, install a new camshaft.

GENERAL PROCEDURES
Camshaft Bearing Journal Clearance
1. N0TE:Make sure that the following stages The value that is read off is the bearing
are followed exactly. The tappets or followers clearance.
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.

GENERAL
PROCEDURES
Camshaft End Play
1. N0TE:Make sure that the camshaft is to
specification.
Using a Dial Indicator Gauge, measure the
end play.
Slide the camshaft in both directions. Read
and note the maximum and minimum values
on the Dial lndicator Gauge.
End play = maximum value minus minimum
value
If the measurement is out of specification,
install new components.

GENERAL PROCEDURES
Camshaft Lobe Lift
1. Determine the cam lift.
Using a micrometer measure the cam in two
directions.
The difference between the two
measurements is the cam
lift.
