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.
INSTALLATION
1. Install timing chain tensioners (secondary) on both sides of cyl-
inder head.
? Install timing chain tensioner with its stopper pin attached.
? Install timing chain tensioner with sliding part facing down-
ward on right-side cylinder head, and with sliding part facing
upward on left-side cylinder head.
? Install new O-ring as shown in the figure.
2. Install valve lifter.
? Install it in the original position.
3. Install camshafts. (Except for 35
th
Anniversary)
