If the thrust clearance is greater than maximum, replace the
camshaft. If necessary, replace the bearing caps and cylinder
head as a set.

INSPECT CAMSHAFT GEAR BACKLASH
Install the camshafts without installing the exhaust cam-
shaft sub−gear (See page EM−51).
Using a dial indicator, measure the backlash.
Standard backlash:
0.020 − 0.200 mm (0.0008 − 0.0079 in.)
Maximum backlash:
0.30 mm (0.0188 in.)
INSPECT VALVE LIFTERS AND LIFTER BORES
Using a caliper gauge, measure the lifter bore diameter
of the cylinder head.
Lifter bore diameter:
31.000 − 31.018 mm (1.2205 − 1.2212 in.)
Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.966 − 30.976 mm (1.2191 − 1.2195 in.)
Subtract the lifter diameter measurement from the lifter
bore diameter measurement.
Standard oil clearance:
0.024 − 0.052 mm (0.0009 − 0.0020 in.)
Maximum oil clearance:
0.08 mm (0.0031 in.)
