lowing parts. If they are out of specification, adjust the valve
clearances.

ADJUSTINGNBEM0022S02Adjust valve clearance while engine is cold.
1. Turn crankshaft, to position cam lobe on camshaft of valve that
must be adjusted upward.
2. Thoroughly wipe off engine oil around adjusting shim using a
rag.
3. Using a extra-fine screwdriver, turn the round hole of the
adjusting shim in the direction of the arrow.

4. Place Tool (A) around camshaft as shown in figure.
Before placing Tool (A), rotate notch toward center of cyl-
inder head (See figure.), to simplify shim removal later.
CAUTION:
Be careful not to damage cam surface with Tool (A).
5. Rotate Tool (A) (See figure.) so that valve lifter is pushed down.
SEM870E
6. Place Tool (B) between camshaft and the edge of the valve
lifter to retain valve lifter.
CAUTION:
ITool (B) must be placed as close to camshaft bracket as
possible.
IBe careful not to damage cam surface with Tool (B).
7. Remove Tool (A).

8. Blow air into the hole to separate adjusting shim from valve
lifter.

9. Remove adjusting shim using a small screwdriver and a mag-
netic finger.
10. Determine replacement adjusting shim size following formula.
IUsing a micrometer determine thickness of removed shim.
ICalculate thickness of new adjusting shim so valve clearance
comes within specified values.
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake:
N=R+[Mþ0.30 mm (0.0118 in)]
Exhaust:
N=R+[Mþ0.33 mm (0.0130 in)]
Shims are available in 64 sizes from 2.32 mm (0.0913 in)
to 2.95 mm (0.1161 in), in steps of 0.01 mm (0.0004 in).
ISelect new shim with thickness as close as possible to calcu-
lated value.

12. Place Tool (A) as mentioned in steps 2 and 3.
13. Remove Tool (B).
14. Remove Tool (A).
15. Recheck valve clearance.

Removal and InstallationNBEM0042WARNING:
ISituate vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled off. Otherwise, you may burn yourself
and/or fire may break out in fuel line.
IFor safety during subsequent steps, the tension of wires
should be slackened against the engine.
IBefore disconnecting fuel hose, release fuel pressure
from fuel line.
Refer to EC-39, ªFuel Pressure Releaseº.
IBefore removing front axle from transmission, place
safety stands under designated front supporting points.
Refer to GI section for lifting points and towing.
IBe sure to hoist engine and transmission in a safe man-
ner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be careful not to strike adjacent parts,
especially accelerator wire casing, brake lines, and brake
master cylinder.
IIn hoisting the engine, always use engine slingers in a
safe manner.
IBefore separating engine and transmission, remove
crankshaft position sensor (POS) from the assembly.
IAlways take extra care not to damage edge of crankshaft
position sensor (POS), or ring gear teeth.GI
