3. Measure the camshaft runout.
4. Measure the camshaft journal diameter
c and camshaft journal inside diameter
d. Replace the camshaft, cylinder head
assembly, or both if out of specification.
Checking the spark plug
1. Clean the electrodes a using a spark
plug cleaner.
2. Check the spark plug. Replace if the
electrodes are eroded, or there is carbon
or other deposits.
3. Check the spark plug gap b. Replace if
out of specification.
Installing the camshaft and driven
sprocket
If the valve clearances are adjusted or any
parts related to valve movement are replaced
after installing the timing belt, check the valve
clearances. See “Checking the valve clear-
ance” (7-2).
• Do not reuse a gasket or oil seal, always
replace it with a new one.
• When the timing belt is not installed, do
not turn the crankshaft or camshafts.
Otherwise, the pistons and valves or
intake and exhaust valves could collide
with each other and be damaged.
