CLEARANCE
(a)
Using a cylinder
gauge,
measure
the
valve
lifter
bore
diameter.
Bore
diameter: 27.O1O
-
27.O3O
mm
(1.0634
-
1.O642 in.)
(b)
Using
a
micrometer,
measure
the valve lifter
dia-
meter.
Lifter
diameter: 26.955
-
26.975
mm
(1.0612
-
1.O620 in.)
(c)
Subtract the valve lifter
diameter measurement
from
the valve lifter
bore diameter
measurement.

Maximum
oilclearance:
O.1O mm
(O.OO39

lf
the oil clearance is
greater
than maximum, replace
the
valve lifters.
