The valve clearance specification is different for intake and
exhaust valves. Valve clearance must be checked and adjusted,
1) at the time of periodic inspection, 2) when the valve mecha-
nism is serviced, and 3) when the camshafts are removed for
servicing.
Valve clearance (when cold):
Standard: IN. : 0.08 – 0.18 mm (0.003 – 0.007 in)
EX. : 0.18 – 0.28 mm (0.007 – 0.011 in)
NOTE:
* The cam must be at positions,
A
or
B
, when checking or
adjusting the valve clearance. Clearance readings should not
be taken with the cam in any other position than these two
positions.
* The clearance specification is for COLD state.
* To turn the crankshaft for clearance checking, be sure to use a
wrench, and rotate in the normal running direction. All spark
plugs should be removed.
• Remove the valve timing inspection cap 1.
Inspect every 24 000 km (14 500 miles, 48 months).
