timing chain cover.
(3) With the piston of the No.4 cylinder positioning at TDC, the valves which can be measured its clearance are as
shown below.
7.Adjust the intake and the exhaust valve clearances.
(1) Set the piston of the No.1 cylinder to the TDC/position.
(2) Remove the timing belt.
(3) Remove the camshaft bearing caps(A, B).
(4)Remove the camshaft assembly.
(5) Remove MLA(Mechanical Lash Adjuster)s.
(6) Measure the thickness of the removed tappet using a micrometer.
(7)Calculate the thickness of a new tappet so that the valve clearance comes within the specified value.
T : Thickness of removed tappet
A : Measured valve clearance

N : Thickness of new tappet
Intake : N = T + [A - 0.20mm(0.0079in.)]
Exhaust : N = T + [A - 0.30mm (0.0118in.)]

3.600mm (0.1417in.)
(9) Place a new tappet on the cylinder head.
Apply engine oil on the periphery surface of the selected tappet.
(10) Install the intake and exhaust camshafts.

REMOVAL
1.Remove the engine cover.
2. Remove the front right wheel and tire.
3. Remove the right side cover.
4. Remove the drive belt(A), the idler(B) and the tensioner(C).

6.Align the groove of the pulley with the timing mark of the timing belt cover by turning the crankshaft pulley
clockwise. Check if the timing mark of the camshaft sprocket is aligned with that of the cylinder head cover at the
moment.
(No.1 cylinder piston at TDC)
7.Remove the engine mounting bracket(A).

Sustain the engine oil pan with a jack.
(1)
Put a wooden or rubber block between the jack and the engine oil pan.
8. Remove the crankshaft damper pulley(A).
9.Remove the timing belt lower cover(A).
10. Remove the engine support bracket(A).
