Maximum backlash: 0.30 mm (0.0188 in.)
If the backlash is greater than maximum, replace the cam-
shafts.
15. INSPECT VALVE LIFTERS AND LIFTER BORES
(a) Using a micrometer, measure the lifter diameter.
Lifter diameter: 27.975 ± 27.985 mm
(1.1014 ± 1.1018 in.)

by measuring the amount of protrusion while
pressing.
