VALVE CLEARANCE






Using a micrometer, measure the thickness of the removed valve lifters.
Calculate the thickness of a new lifter so that the valve clearance comes within the specified range.

New lifter thickness:










CALCULATION EXAMPLE (Intake):

Measured intake valve clearance = 0.40 mm (0.0158 in.)
(Measured - Specification = Excess clearance)
0.40 mm (0.0158 in.) - 0.24 mm (0.0095 in.) = 0.16 mm (0.0063 in.)

Measured used lifter thickness = 5.250 mm (0.2067 in.)
New lifter thickness = 5.410 mm (0.2130 in.)
(Excess clearance + Used lifter thickness = Ideal new lifter)
0.16 mm (0.0063 in.) + 5.250 mm (0.2067 in.) = 5.410 mm (0.2130 in.)

Closest new lifter = 5.420 mm (0.2134 in.)

Select No. 42 lifter





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

Lifters are available in 35 sizes in increments of 0.020 mm (0.0008 in.), from 5.060 to 5.740 mm (0.1992 to 0.2260 in.).
The identification number inside the valve lifters shows the value to 2 decimal places. (The illustration shows 5.420 mm (0.2134 in.))

New lifter thickness






Standard intake valve clearance (cold) 0.19 to 0.29 mm (0.0075 to 0.0114 in.)

The 5.250 mm (0.2067 in.) lifter is installed, and the measured clearance is 0.400 mm (0.0157 in.). Replace the 5.250 mm (0.2067 in.) lifter with a new No. 42 lifter.

New lifter thickness






Standard exhaust valve clearance (cold) 0.38 to 0.48 mm (0.0150 to 0.0189 in.)

The 5.340 mm (0.2102 in.) lifter is installed, and the measured clearance is 0.510 mm (0.0201 in.). Replace the 5.340 mm (0.2102 in.) lifter with a new No. 42 lifter.
