(1) Insert a thin screwdriver into the notch
in the valve lifter.
(2) Carefully pry up the valve pad and
remove it.
(3) Measure the thickness removed valve
pad with a micrometer.
(4) Select a proper replacement valve pad
by calculating its thickness with the
following formula.
(5) Install the proper valve pad into the
valve lifter.
NOTE:
• Measure the thickness of the new valve
pad with a micrometer because the thick-
ness number is not indicated on the pad.
• Lubricate the valve pad with molybdenum
disulfide grease.
• Perform the above procedure for all
valves whose clearances are out of speci-
fication.
Proper valve pad thickness =
Removed valve pad thickness +
Measured valve clearance –
Specified valve clearance
11. Install:
• Camshafts
• Camshaft caps
• Driven sprockets
• Timing belt
12. Tighten:
• Timing belt tensioner
Refer to “POWER UNIT” on page 5-4.
13. Recheck:
• Valve clearance
NOTE:
If any valve clearance is still out of specifi-
cation, repeat all of the valve clearance
adjustment steps until the specified clear-
ance is obtained.
