Adjustment steps:
● Insert a thin screwdriver into the notch
in the valve lifter.
● Carefully pry up the valve pad and
remove it.
● Measure the thickness removed valve
pad with a micrometer.
● Select a proper replacement valve pad
by calculating its thickness with the
following formula.
Proper valve pad thickness =
Removed valve pad thickness +
Measured valve clearance –
Specified valve clearance
● Install the proper valve pad into the
valve lifter.
NOTE:
● Measure the thickness of the new valve
pad with a micrometer because the
thickness number is not indicated on the
pad.
● Lubricate the valve pad with molybde-
num disulfide grease.
● Perform the above procedure for all
valves whose clearances are out of spec-
ification.
11. Install:
● Camshafts
● Camshaft caps
● Driven sprockets
● Timing belt
12. Tighten:
● Timing belt tensioner
Refer to “POWER UNIT” in chapter 5.
13. Recheck:
● Valve clearance
NOTE:
If any valve clearance is still out of specifi-
