VALVE LIFTER HOLE DIAMETER
Measure inner diameter of valve lifter hole of cylinder head with
inside micrometer.
VALVE LIFTER CLEARANCE
(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)
If it exceeds the standard, referring to each standard of valve lifter outer diameter and valve lifter hole
diameter, replace either or both valve lifter and cylinder head.
INSTALLATION
1. Install valve lifters and adjusting shims if removed.
Install it in the original position.
2. Install camshafts.
Follow your identification marks made during removal, or fol-
low the identification marks that are present on new cam-
shafts for proper placement and direction.
Install camshaft so that dowel pin on front end face are posi-
tioned as shown in the figure. (No. 1 cylinder TDC on its com-
pression stroke)
NOTE:
Though camshaft does not stop at the position as shown in
the figure, for the placement of cam nose, it is generally
accepted camshaft is placed for the same direction of the fig-

RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS".
CAUTION:
After installation, be sure to wipe off any excessive liq-
uid gasket leaking from part “A” and “B” (both on right
and left sides).
Remove completely any excess of liquid gasket inside
bracket.
Apply liquid gasket to mating surface of camshaft bracket (No.

INSPECTION
In cases of removing/installing or replacing camshaft and valve-related parts, or of unusual engine conditions
due to changes in valve clearance (found malfunctions during starting, idling or causing noise), perform
inspection as follows:
1. Warm up engine. Then stop it.
2. Remove rocker covers (right and left bank). Refer to EM-193, "
ROCKER COVER" .
3. Measure valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke. : 1.96 N·m (0.2 kg-m, 1 ft-lb)

Make sure that both intake and exhaust cam noses of No. 1
cylinder (engine front side of left bank) are located as shown
in the figure.
If not, turn crankshaft one revolution (360 degrees) and align

CAUTION:
Adjust valve clearance while engine is cold.
After adjusting, make sure that the valve clearance is within the standard while engine is hot.
1. Thoroughly wipe off engine oil around adjusting shim using rag.
2. Rotate crankshaft to position cam nose on camshaft of valve that must be adjusted upward.
3. Using small screwdriver, turn the round hole of adjusting shim in
the direction of the arrow.
CAUTION:
perform (the above procedure) during camshaft do not con-
tact with adjusting shim.
4. Install lifter stopper [SST: 10115120 (J38972-2)] as follows:
a. Except exhaust side of No. 7 and No. 8 cylinder;
i. Place camshaft pliers (SST) around camshaft as shown in the
figure.
ii. Rotate camshaft pliers so that valve lifter is pushed down.
CAUTION:
Be careful not to damage cam surface, valve lifter and cylin-
der head with camshaft pliers.

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 No. 8 cylinder;
NOTE:
Exhaust side of No. 7 and No. 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.

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).
Thickness of new adjusting shim can be identified by stamp
