Nissan Almera Tino V10. Instruction — part 878
EM-168
[YD]
CAMSHAFT
●
Measure the valve clearance using a fine feeler gauge when
the engine is cool (at normal temperature).
10. Set the No. 4 cylinder at TDC by rotating the crankshaft clock-
wise once.
11. While referring to the figure, measure the valve clearance
marked in the table below.
12. If the valve clearance is outside the specification, adjust as fol-
lows.
ADJUSTMENTS
●
Remove the adjusting shim for parts which are outside the spec-
ified valve clearance.
1.
Remove the spill tube. Refer to
EM-147, "Removal and Installa-
.
2.
Extract the engine oil on the upper side of the cylinder head (for
the air blowing in step 7).
3.
Rotate the crankshaft to face the camshaft for adjusting shims
that are to be removed upward.
4.
Grip the camshaft with camshaft pliers, them using the camshaft
as a support point, push the adjusting shim downward to com-
press the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head and the outer
circumference of the valve lifter.
Valve clearance (Cold):
Standard:
Intake
: 0.24 - 0.32 mm (0.0094 - 0.0126 in)
Exhaust
: 0.26 - 0.34 mm (0.0102 - 0.0134 in)

5.
With the valve spring in a compressed state, remove the cam-
shaft pliers by securely setting the outer circumference of the
valve lifter with the end of the lifter stopper.
●
Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the cam-
shaft will be damaged.
6.
Move the rounded hole of the adjusting shim to the front with a
very thin screwdriver or like that.
●
When the adjusting shim on the valve lifter will not rotate
smoothly, restart from step 4 to release the end of the lifter
stopper from touching the adjusting shim.
7.
Remove the adjusting shim from the valve lifter by blowing air
through the rounded hole of the shim with an air gun.
CAUTION:
To prevent any remaining oil from being blown around,
thoroughly wipe the area clean and wear protective gog-
gles.
8.
Remove the adjusting shim by using a magnetic hand.
9.
Measure the thickness of the adjusting shim using a micrometer.
●
Measure near the center of the shim (the part that touches the
camshaft).
10. Select the new adjusting shim from the following methods.
SBIA0185E
SBIA0186E
SBIA0187E
Calculation method of the adjusting shim thickness:
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake
N = R + [M - 0.28 mm (0.0010 in)]
Exhaust
N = R + [M - 0.30 mm (0.0118 in)]

●
New adjusting shims have the thickness stamped on the rear
side.
●
Shims are available in 33 size from 2.10 mm (0.0827 in) to
2.74 mm (0.1079 in), in steps of 0.02 mm (0.0008 in).
11. Fit the selected adjusting shim to the valve lifter.
CAUTION:
Place the stamped side of the adjusting shim to the valve
lifter.
12. Compress the valve spring using the camshaft pliers and
remove the lifter stopper.
13. Rotate the crankshaft 2 to 3 turns by hand.
14. Confirm that the valve clearance is within the specification.
Valve clearance:
*: Approximately 80
°
C (176
°
F)
15. Install remaining parts in reverse order of removal.
