Install the camshaft sprocket and tighten the bolt to the specified torque.
Temporarily install the camshaft sprocket bolt(C).
Hold the portion(A) of the camshaft with a hexagonal wrench, and tighten the bolt(C) with a wrench(B) .
Tightening torque :
78.5 ~ 98.1N.m (8.0 ~ 10.0kgf.m, 57.9 ~ 72.3lb-ft)
Install the cylinder head cover.
Install the cylinder head cover(A) and bolts(B).
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
Install the PCV(Positive Crankcase Ventilation) hose(A) and breather hose(B) to the cylinder head cover.
Install the ignition coil.
Install the crankshaft sprocket(A).
Align the timing marks of the camshaft sprocket(A) and crankshaft sprocket(B) with the No.1 piston placed at top dead center and its compression stroke.
Install the idler pulley(A) and tighten the bolt(B) to the specified torque.
Tightening torque :
42.2 ~ 53.9N.m (4.3 ~ 5.5kgf.m, 31.1 ~ 39.8lb-ft)
Temporarily install the timing belt tensioner(A).
Install the belt so as not give slack at each center of shaft. Use the following order when installing timing belt.
Crankshaft sprocket(A) →idler pulley(B) →camshaft sprocket(C) →timing belt tensioner(D).
Adjust the timing belt tension.
Give tension to timing belt using the tensioner's elasticity after loosening the mounting bolt (A,B).
After checking the alignment between each sprocket and each timing belt tooth, tighten the mounting bolt (A) and (B) one by one.
Tightening torque :
19.6 ~ 26.5N.m (2.0 ~ 2.7kgf.m, 14.5 ~ 19.5lb-ft)
Then recheck the belt tension.
Verify that when the tensioner and the tension side of the timing belt are pushed in horizontally with a moderate force [approx. 49N (11lb)], the timing belt cog end is aprox. 1/2 of the tensioner mounting bolt head radius (across flats) away from the bolt head center.
Timing belt tension measuring procedure [Using a mechanical tension gauge (BT-33-73F, BTG-2 type)]
Rotate crankshaft in clockwise direction to set 1st piston on top dead center (TDC) and rotate crankshaft in counterclockwise to 90° then measure the belt tension in the middle of tension side span (in both arrow direction of above illustration ) by free vibration method.
When rotating the crankshaft counter-clockwise, be sure to rotate the crankshaft at a time.
Input the belt specifications into the tension meter.
Location of measurement | Input data | |||
M (Mass, g/m.mm) | W (Width, mm) | S (Span, mm) | ||
T1 | Camshaft sprocket to crankshaft sprocket | 4.5 | 22 | 250 |
T2 | Camshaft sprocket to tensioner | 4.5 | 22 | 231 |
Locate the micro phone close to the center of belt span (T1, T2) and bounce the belt by finger 2~3 times. Read a value on the display.
Measure both T1 and T2 at the A and B points respectively and then calculatethe average
Average Belt Tension (T)
Without CVVT(1.4L/1.6L): 20±3.5 kgf
With CVVT(1.6L): 18±3.5 kgf
Turn the crankshaft two turns in the operating direction (clockwise) and realign crankshaft sprocket and camshaft sprocket timing mark.
Install the timing belt lower cover(A) with 5bolts(B).
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
Install the flange and crankshaft pulley(A), and then tighten crankshaft pulley bolt.
Make sure that crankshaft sprocket pin fits the small hole in the pulley.
Tightening torque :
137.3 ~ 147.1N.m (14.0 ~ 15.0kgf.m, 101.3 ~ 108.5lb-ft)
Install the timing belt upper cover(A) with 4 bolts(B).
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
