6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to EM-238, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set try square along the side of valve spring and rotate spring.
Measure the maximum clearance between the top face of spring
and try square.

If it exceeds the limit, replace valve spring.
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD

Check valve spring pressure at the specified spring height.

If the installation load or load with valve open is out of the standard, replace valve spring. Limit : 2.0 mm (0.079 in)

Intake and exhaustFree height : 46.35 - 46.85 mm (1.8247 - 1.8444 in)
Installation height : 33.8 mm (1.331 in)
Installation load : 165 - 189 N (16.8 - 19.3 kg, 37 - 42 lb)
Height during valve open : 24.4 mm (0.961 in)

If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to EM-
270, "MAIN BEARING OIL CLEARANCE" .
CRANKSHAFT PIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft pin journal with
micrometer.

If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-269,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.

Out-of-round is indicated by the difference in the dimensions
between “X” and “Y” at “A” and “B”.

Taper is indicated by the difference in the dimensions between
“A” and “B” at “X” and “Y”.

If the measured value exceeds the limit, correct or replace crankshaft.

If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select the main bearing and/or connecting rod bearing. Refer to EM-270, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-269, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block on precise flat table, and support the journals on
the both end of crankshaft.

Place dial indicator straight up on the No. 3 journal.

While rotating crankshaft, read the movement of the pointer on
dial indicator. (Total indicator reading)

If it exceeds the limit, replace crankshaft. Standard : 63.940 - 63.964 mm (2.5173 - 2.5183 in) dia.
Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.
