Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 4 jour- nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on a dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer.
2. If wear exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER

Measure the outer diameter of camshaft journal with a microme-
ter.
CAMSHAFT BRACKET INNER DIAMETER

Tighten camshaft bracket bolt with the specified torque. Refer to EM-89, "INSTALLATION" for the tighten-
ing procedure.

If it exceeds the limit, replace camshaft sprocket.
Valve Lifter
Check if surface of valve lifter has any wear or cracks.

If anything above is found, replace valve lifter. Refer to EM-153,
"Available Valve Lifter" .
Valve Lifter Clearance
VALVE LIFTER OUTER DIAMETER

Measure the outer diameter at 1/2 height of valve lifter with a
micrometer since valve lifter is in barrel shape.
VALVE LIFTER HOLE DIAMETER

Measure the inner diameter of valve lifter hole of cylinder head
with an inside micrometer.
VALVE LIFTER CLEARANCE

(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)

If the calculated value is out of 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. Limit : 0.15 mm (0.0059 in)
