• Measure the inner diameter of camshaft bracket with a bore gauge
(A).
CAMSHAFT JOURNAL OIL CLEARANCE
• (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
• If it exceeds the limit, replace camshaft or cylinder head, or both. NOTE:
Camshaft bracket cannot be replaced as a single part , because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play 1. Install camshaft in cylinder head.
2. Install dial indicator in thrust direction on front end of camshaft. Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).
• Measure the following parts if out of the standard.
- Dimension (A) for groove of cylinder head No. 1 journal
- Dimension (B) for camshaft flange
• Apply the standards above, and then replace camshaft and/or cylinder head, if necessary.
Camshaft Sprocket Runout 1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft. CAUTION:
Never support No. 1 journal (on the side of cam shaft sprocket) because it has a different diameter
from the other four locations. B : Measuring direction of inner diameter

Valve Lifter
Check if surface of valve lifter has any wear or cracks.
• If anything above is found, replace valve lifter. Refer to EM-178," Valve Clearance " .
Valve Lifter Clearance
VALVE LIFTER OUTER DIAMETER
• Measure the outer diameter of valve lifter with a micrometer (A).
VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer (A).
VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)
• If out of the standard, referring to the each standard of va lve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
