Valve Clearance: Adjustment
WARNING: This page is about a different variant/trim than selected.
- Measure all the valve clearances. Ref. to
INSPECTION , Valve Clearance.NOTE: Record the measured value of each valve clearance.
- Remove the camshaft. Ref. to REMOVAL , Camshaft.
- Remove the valve lifter.
- Measure the thickness of valve lifter using micrometer.
- Select a valve lifter of suitable thickness using the measured valve clearance and valve lifter thickness, and install it.NOTE: Use a new valve lifter.VALVE LIFTER SPECIFICATIONS
Unit: mm (in) Intake valve: S = (V + T) - 0.19 (0.0075)
Exhaust valve: S = (V + T) - 0.35 (0.0138)S: Valve lifter thickness required
V: Measured valve clearance
T: Valve lifter thickness to be used - Install the camshaft. Ref. to INSTALLATION , Camshaft.
- Install the cam sprocket. Ref. to INSTALLATION , Cam Sprocket.
- Install the timing belt. Ref. to TIMING BELT , INSTALLATION, Timing Belt.
- Measure all valves for valve clearance again at this time. If the valve clearance is not within the adjustment value, repeat the procedure over again from the first step.
Valve clearance (adjustment value):
Intake
0.20 +001 -0.03 mm (0.0079 +00004 -0.0012 in)
Exhaust
0.35±0.02 mm (0.0138±0.0008 in)
- After adjustment, install the related parts in the reverse order of removal.NOTE:
- Refer to "Camshaft" when installing the rocker cover. Ref. to INSTALLATION , Camshaft.
- Use a new clamp for the PCV hose clamp, fit the cut out in the ST with the protrusion on the clamp as shown in the figure, and lock the clamp.
