3. Inspect the cylinder for pitting, scoring, scuffing, and
corrosion. If marks are found, repair the surface using
a #320 grit ball hone.
 NOTE: To produce the proper 60° cross-hatch pat-
tern, use a low RPM drill (600 RPM) at the rate of 30
strokes per minute. If honing oil is not available, use
a lightweight petroleum-based oil. Thoroughly clean
cylinder after honing using soap and hot water. Dry
with compressed air; then immediately apply oil to
the cylinder bore. If the bore is severely damaged or
gouged, replace the cylinder.
4. If any measurement exceeds the limit, replace the cyl-
inder and piston.
Measuring Camshaft Runout
 NOTE: If the camshaft is out of tolerance, it must be
replaced.
1. Place the camshaft on a set of V blocks; then position
the dial indicator contact point against the shaft and
zero the indicator.
2. Rotate the camshaft and note runout; maximum toler-
ance must not exceed specifications.
Measuring Camshaft Lobe Height
1. Using a calipers, measure each cam lobe height.
2. The lobe heights must not exceed minimum specifica-
tions.
Inspecting Camshaft Bearing
Journal
1. Inspect the bearing journal for scoring, seizure marks,
or pitting.
2. If excessive scoring, seizure marks, or pitting is found,
the cylinder head assembly must be replaced.
Measuring Camshaft to Cylinder
Head Clearance
CC390D
1. Remove the adjuster screws and jam nuts.
2. Place a strip of plasti-gauge in each of the camshaft
lands in the cylinder head.
3. Place the valve cover on the cylinder head and secure
with the valve cover cap screws. Tighten securely.
 NOTE: Do not rotate the camshaft when measuring
clearance.
CC283D
4. Remove the cap screws securing the valve cover to the
cylinder; then remove the valve cover and camshaft.
5. Match the width of the plasti-gauge with the chart
found on the plasti-gauge packaging to determine
camshaft to cylinder head and valve cover clearance.
