Rondo V6-2.7L (2009)
Exhaust : 0.20 - 0.40mm (0.0079 - 0.0157in.)
(2) Turn the crankshaft pulley one revolution (360°) clockwise and align the groove with the timing mark "T" of the 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.)]
(8) Select a new tappet with a thickness as close as possible to the calculated value.
NOTE:
Tappets are available with 41different size increments of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to 3.600mm (0.1417in.)
(9) Place a new tappet on the cylinder head.
NOTE:
Apply engine oil on the periphery surface of the selected tappet.
(10) Install the intake and exhaust camshafts.
(11) Install the bearing caps.
(12) Install the timing belt.
