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 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.
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.
Using micrometer determine thickness of removed shim with
measured at center.
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-277, "
