Repair/Removal.
(e) Remove the camshaft See: Engine, Cooling and Exhaust/Engine/Camshaft, Lifters and Push Rods/Camshaft/Service and Repair/Removal.
(f) Remove the valve lifters.
(g) Using a micrometer, measure the thickness of the removed valve lifters.
(h) Calculate the thickness of a new lifter so that the valve clearance comes within the specified range.
New Lifter Thickness:
CALCULATION EXAMPLE (Intake):
1. Measured intake valve clearance = 0.40 mm (0.0157 in.)
(Measured - Specification = Excess clearance)
1
0.40 mm (0.0157 in.) - 0.24 mm (0.00945 in.) = 0.16 mm (0.00630 in.)
2. Measured used lifter thickness = 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 (0.00630 in.) + 5.250 mm (0.2067 in.) = 5.410 mm (0.2130 in.)
4. Closest new lifter = 5.420 mm (0.2134 in.)
-
Select No. 42 lifter
(i) Select a new lifter with a thickness as close as possible to the calculated values.
HINT:
-
Lifters are available in 35 sizes in increments of 0.020 mm (0.000787 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.).
