MAINTENANCE
ADJUSTMENT
NORMAL VALVE SIDE
Remove
the valve lifters and shims
from the
normal
side
valve
lifter bores (page
10-9).
Clean
the valve shim [1] contact area in
the valve lifter
with compressed air.
Measure the shim
thickness and
record it.
NOTE:
.
Sixty-five different thickness
shims
are
available
from
1.200 mm to 2.800 mm
thickness
in intervals of
0.025 mm.
Calculate
the new shim thickness using
the
equation
below:
A=(B-C)*O
A: New shim thickness
B: Recorded valve clearance
C: Specified
valve
clearance
D: Old shim thickness
NOTE:
.
Make sure
of
the correct shim thickness
by
measuring the shim with the micrometer'
.
Reface
the valve
seat
if carbon deposit result
in
a
calculated dimension of over 2.800 mm
lnstall
the newly selected
shims
[1] onto the
valve
retainers,
Apply molybdenum
oil
solution
to the valve lifters
[2]
outer sliding surface,
lnstall the
valve lifters in their
original locations
VTEC
VALVE SIDE
Remove
the valve
lifters
and slide pin
holders
from
the
VTEC side
valve lifter bores
(page
10-9)
Clean
the valve contact
areas in
the slide pin
holder
and
valve lifter with compressed air,
Measure the
valve
lifter thickness of the
slide
pin holder
contact area [1]
and record
it.
NOTE:
.
Sixty-five
different thickness
valve lifters
are
available
from
1.200 mm to 2.800 mm thickness
in
intervals
of
0.025
mm (the thickness letter
[2] is
located near the
contact area).
Calculate
the new valve lifter thickness
using
the
equation below:
A=(B-C)+D
A:
New
valve lifter thickness
B: Recorded
valve clearance
C: Specified
valve clearance
D: Old
valve
lifter thickness
