4.
Fasten a temporary pointer to the timing case cover.
The tip of the temporary pointer should be near the
outer edge of the crankshaft pulley or the damper.
Make a temporary mark on the crankshaft pulley or the
damper which aligns with the temporary pointer.
5.
Remove the timing pin.
6.
When the engine is viewed from the front, rotate the
crankshaft in a clockwise direction. Rotate the
crankshaft until the inlet valve of the rear cylinder is fully
open.
7.
Set the valve lash of the number 1 inlet valve to 1.50
mm (0.059 inch).
8.
When the engine is viewed from the front, rotate the
crankshaft in a clockwise direction until the pushrod of
the inlet valve for number 1 cylinder begins to tighten.
In this position, make sure that the mark on the
crankshaft pulley or the damper is within : 2.5 degrees
of the temporary pointer indicator.
NOTE: Use the following formula in order to calculate the
measurement which is equal to 2.5 degrees on the
pulley or damper:
Table 13.
Formula For Calculating The Measurement
on The Pulley or The Damper
(C X P)/360 = M
C is the circumference of the pulley or the damper.
P is equal to 2.5 degrees.
M is the measurement which is equal to 2.5 degrees on the pulley
or the damper.
9.
If the timing is more than 2.5 degrees out of position, the
timing gears are not in correct alignment.
One tooth on the camshaft gear is equivalent to 23 mm
(0.91 inch) at the circumference of a pulley of 203 mm
(7.99 inch) diameter. If a large damper is installed, one
tooth on the camshaft gear is equivalent to the following
measurements:
35 mm (1.38 inch) at the circumference of a damper of
310 mm (12.20 inch) diameter
37 mm (1.46 inch) at the circumference of a damper of
327 mm (12.87 inch) diameter
10.
When the engine is viewed from the front, rotate the
crankshaft in a clockwise direction until the inlet valve of
the rear cylinder is fully open. Refer to Specifications,
"Cylinder Head Valves" for the correct valve lash.
