Work Procedure
WARNING: This page is about a different variant/trim than selected.
- Perform adjustment depending on selected head thickness of valve lifter.
- Remove camshaft. Refer to Removal and Installation .
- Remove valve lifters at the locations that are out of the standard.
- Measure the center thickness of the removed valve lifters with a suitable tool (A).
- Use the equation below to calculate valve lifter thickness for replacement.
Valve lifter thickness calculation:
t = t 1 + (C 1 - C 2 )
t
= Valve lifter thickness to be replaced
t 1
= Removed valve lifter thickness
C 1
= Measured valve clearance
C 2
= Standard valve clearance:
Intake
: 0.31 mm (0.0122 in)
Exhaust
: 0.32 mm (0.0126 in)
- Thickness of new valve lifter (B) can be identified by stamp mark (A) on the reverse side (inside the cylinder).
- Stamp mark \"302\" indicates 3.02 mm (0.1189 in) in thickness.
NOTE: Available thickness of valve lifter: 26 sizes range 3.00 to 3.50 mm (0.1181 to 0.1378 in) in steps of 0.02 mm (0.0008 in) (when manufactured at factory). Refer to Service Data . - Thickness of new valve lifter (B) can be identified by stamp mark (A) on the reverse side (inside the cylinder).
- Install the selected valve lifter.
- Install camshaft. Refer to Removal and Installation .
- Install timing chain and related parts. Refer to Removal and Installation .
- Manually rotate crankshaft pulley a few rotations.
- Check that the valve clearance is within the standard. Refer to How to Check .
- Installation of the remaining parts is in the reverse order of removal.
- Warm up the engine, and check for unusual noise and vibration.
