(5) Rotate the crankshaft so that the camshaft is posi-
tioned as shown in the illustration.
NOTICE:
S
Pay attention to the direction of the rotation to prevent
the nose of the camshaft from interfering with the
SST’s shaft.
S
Do not rotate the crankshaft excessively.
(b) Remove the adjusting shim.
(1)
Lift the rocker arm to make a room and remove the
adjusting shim using SST.
SST 09248 − 77010 (09248 − 07020)
NOTICE:
Do not remove SST in the condition that the adjusting shim
is removed.
HINT:
S
Setting SST from the right above makes the removal
easy.
S
If there is not enough room, reset SST.
(2) Determine the size of the replaced shim according
to these Formula or Charts:
S
Using dial indicator, measure the thickness of
the removed shim.
S
Calculate the thickness of a new shim so the
valve clearance comes within the specified
value.
T.......... Thickness of used shim
A......... Measured valve clearance
N......... Thickness of new shim
Intake: N = T+ (A
− 0.13 mm (0.0051 in.)) x 1.5
Exhaust: N = T+ (A − 0.27 mm (0.0106 in.)) x 1.5
S
Select a new shim with a thickness as close
as possible to the calculated values.
HINT:
Shim are available in 41 size in increments of 0.020 mm (0.0008
in.), from 2.000 mm (0.0787 in.) to 2.800 mm (0.1102 in.).
