1

Using a micrometer, measure the thickness of the removed lifter

2

Calculate the thickness of a new lifter so that the valve clearance comes within the specified
value

T: Thickness of removed lifter

A: Measured valve clearance

N: Thickness of new lifter

Intake: N = T + (A - 0.20 mm (0.00787 in.))

Exhaust: N = T + (A - 0.30 mm (0.0118 in.))

3

Select a new lifter with a thickness as close as possible to the calculated value

HINT:

Lifters are available in 35 sizes in increments of 0 020 mm (0 000787 in ), from 5 060 mm
(0 1992 in ) to 5 740 mm (0 2260 in )
