Tucson AWD L4-2.4L (2010)
J. Calculate the thickness of a new tappet so that the valve clearance comes within the specified value.
Valve clearance (Engine coolant temperature : 20°C [68°F])
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.)]
K. Select a new tappet with a thickness as close as possible to the calculated value.
NOTE:
Shims are available in 47size increments of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to 3.690mm (0.1452in.)
L. Place a new tappet on the cylinder head.
M. Hold the timing chain, and install the intake camshaft and CVVT assembly.
N. Align the matchmarks on the timing chain and CVVT sprocket.
O. Install the exhaust camshaft and CVVT assembly.
P. Install the front bearing cap.
Tightening torque :
14.7N.m (1.5kgf.m, 10.8lb-ft) + 27.4 - 31.4N.m (2.8 - 3.2kgf.m, 20.3 - 23.1lb-ft)
Q. Install the service hole bolt.
Tightening torque :
11.8 - 14.7N.m (1.2 - 1.5kgf.m, 8.7 - 10.8lb-ft)
R. Turn the crankshaft two turns in the operating direction(clockwise) and realign crankshaft sprocket and CVVT sprocket timing marks (A).
S. Recheck the valve clearance.
Valve clearance (Engine coolant temperature : 20°C [68°F])
[Specification]
Intake : 0.17 - 0.23mm (0.0067 - 0.0090in.)
Exhaust : 0.27 - 0.33mm (0.0106 - 0.0129in.)
