(2) Measure the valve clearance.
Standard value:
Cold engine Checking Adjusting
Intake valve mm 0.15- 0.20 0.20
Exhaust valve mm 0.35- 0.45 0.40
(3) If the valve clearance is outside the standard value, adjust
by replacing the tappets using the following procedure.
(4) Take valve clearance measurement again at the cylinder
where the valve clearance is not within the tolerance,
and record the measured value.
(5) Measure the wall thickness (X) of the tappet using a
micrometer, and record the measured value.
(6) Based on the measurements, select a tappet which will
bring the valve clearance to the standard value.
Wall thickness of tappet to be selected =
Wall thickness (X) of tappet having been installed
at checking + (Measured value - Standard value)
NOTE
1. Always use new tappets.
2. Tappets are available in thickness from 7.550 mm to
8.150 mm, increasing by increments of 0.025 mm.
(7) Remove the camshaft. Install the selected tappet.
(8) Install the camshaft.
(9) Rotate the camshaft one turn, then check that the valve
