iii. Place lifter stopper between camshaft and the edge of valve
lifter to retain valve lifter.
CAUTION:
Lifter stopper must be placed as close to camshaft
bracket as possible.
Be careful not to damage cam surface, valve lifter and
cylinder head with lifter stopper.
iv. Remove camshaft pliers.
CAUTION:
Camshaft pliers should be removed by rotating it slowly
because lifter stopper hits and damages journal portion by
rotating camshaft pliers quickly.
b. Exhaust side of No. 7 and 8 cylinder;
NOTE:
Exhaust side of No. 7 and 8 cylinder does not have space for installing camshaft pliers [SST: KV10115110
(J38972-1)]. therefore, install lifter stopper [SST: KV10115120 (J38972-2)] according to the following
instructions.
i. Rotate crankshaft to press cam nose to the adjusting part of valve lifter.
ii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter.
CAUTION:
Lifter stopper must be placed as close to camshaft bracket as possible.
Be careful not to damage cam surface, valve lifter and cylinder head with lifter stopper.
iii. Rotate crankshaft slowly 180 degrees clockwise.
CAUTION:
Rotating crankshaft slowly because lifter stopper hits and damages journal portion by rotating
crankshaft quickly.
5. Blow air into the round hole to separate adjusting shim from
valve lifter.
CAUTION:
When blowing, use goggles to protect your eye.
6. Remove adjusting shim with magnetic hand.
7. Use the equation below to calculate adjusting shim thickness for replacement.

Calculate thickness of new adjusting shim so valve clearance comes within specified values.
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). Refer to EM-278, "
Available Adjusting Shims" .
Thickness of new adjusting shim can be identified by stamp
marks on the reverse side (inside the cylinder).
8. Install new adjusting shim using suitable tool.
Install with the surface on which the thickness is
stamped facing down.
9. Remove lifter stopper as follows:

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-809, "
FUEL PRESSURE RELEASE" .
a. Remove fuel pump fuse to avoid fuel injection during measure-
ment.
3. Remove engine cover with power tool. Refer to EM-173, "
ENGINE ROOM COVER" .
4. Remove ignition coil and spark plug from each cylinder. Refer to EM-190, "
IGNITION COIL" and EM-191,
"SPARK PLUG (PLATINUM-TIPPED TYPE)" .
5. Connect engine tachometer (not required in use of CONSULT-II).
6. Install compression gauge with adapter (SST or commercial ser-
vice tool) onto spark plug hole.
Use compression gauge adapter (SST) which is required on
No. 7 and 8 cylinders.
Use compression gauge adapter (if no SST is used) whose
picking up end inserted to spark plug hole is smaller than 20
mm (0.79 in) in diameter. Otherwise, it may be caught by cyl-
inder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.
