7. Install valve collet.

Compress valve spring with valve spring compressor, attach-
ment and adapter (SST). Install valve collet with magnetic
hand.
CAUTION:
When working, take care not to damage valve lifter holes.

Tap stem edge lightly with plastic hammer after installation to
check its installed condition.
8. Install valve lifter and adjusting shim.

Install in the original position.
9. Install spark plug tube as follows:

Press-fit spark plug tube following procedure below.
a. Remove old liquid gasket adhering to cylinder-head mounting hole.
b. Apply sealant to area within approximately 12 mm (0.47 in) from edge of spark plug tube press-fit side. Use Genuine High Strength Locking Sealant or equivalent. Refer to GI-48, "
RECOMMENDED
CHEMICAL PRODUCTS AND SEALANTS" .
c. Using drift, press-fit spark plug tube so that its height “H” is as specified in the figure.
CAUTION:

When press-fitting, take care not to deform spark plug
tube.

After press-fitting, wipe off liquid gasket protruding onto
cylinder head upper face.
10. Install spark plug with spark plug wrench (commercial service tool).

CRUSH HEIGHT OF MAIN BEARING

When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-253, "
ASSEMBLY" for the tight-
ening procedure.

If the standard is not met, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-253,
"ASSEMBLY" for the tightening procedure.

If the standard is not met, replace connecting rod bearings.
DRIVE PLATE

Check drive plate and signal plate for deformation or cracks.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate. Standard : There must be crush height.
