New lifter thickness:

Item	Specification
Intake	A = B + (C - 0.24 mm (0.0095 in.))
Exhaust	A = B + (C - 0.43 mm (0.0169 in.))

1. Measured intake valve clearance = 0.40 mm (0.0158 in.)
   (Measured - Specification = Excess clearance)
   
1. 0.40 mm (0.0158 in.) - 0.24 mm (0.0095 in.) = 0.16 mm (0.0063 in.)
   
2. Measured used lifter measurement = 5.250 mm (0.2067 in.)
   
3. New lifter thickness = 5.410 mm (0.2130 in.)
   (Excess clearance + Used lifter thickness = Ideal new lifter)
   
1. 0.16 mm (0.0063 in.) + 5.250 mm (0.2067 in.) = 5.410 mm (0.2130 in.)
   
4. Closest new lifter = 5.420 mm (0.2134 in.)
   
1. Select No. 42 lifter
