(o) Tie the chain with a piece of string as shown in the illustration.
(p) Remove the 16 valve lifters.
(q) Using a micrometer, measure the thickness of the removed lifter.
(r)
Calculate the thickness of a new lifter so that the valve clearance comes to within the specified values.
Valve clearance:
Intake A = B + (C - 0.20 mm (0.008 in.))
Exhaust A = B + (C - 0.30 mm (0.012 in.))
(s)
Select a new lifter with a thickness as close to the calculated values as possible.
HINT: Lifters are available in 35 sizes in increments of 0.020mm (0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).
