Belt deflection : 5 ~ 7 mm (0.20 ~ 0.28 in)

Method 2 : Measure the tension of the timing belt by using a tension gauge.
Span length Pressure Torque
139mm (5.47 in.) 0.42 kg/cm ²
(42 kPa) 50 ~ 100Nm
(500 ~ 1000kg.cm, 36 ~ 72 lb.ft)

9. Install the flange and crankshaft sprocket onto the crankshaft. Be sure to install the as shown in the illustration.

Pay attention to the direction of the flange. If it is installed in the wrong direction, a broken belt could result.

10. Install the special washer and sprocket bolt to the crankshaft and then tighten the sprocket bolt.

Tightening torque
Crankshaft sprocket bolt :
160 ~ 170 Nm (1600 ~ 1700 kg.cm, 116 ~ 123 lb.ft)

11. Insert a screwdriver through the plug hole in the left side of the cylinder block to keep the shaft in position.

12. Install the oil pump sprocket and tighten the nut to the specified torque.

Tightening torque
Oil pump sprocket
50 ~ 60 Nm (500 ~ 600 kg.cm, 36 ~ 43 lb.ft)

13. Install the camshaft sprocket and tighten the bolt to the specified torque.

Tightening torque
Camshaft sprocket bolt :
80 ~ 100 Nm (800 ~ 1000 kg.cm, 58 ~ 72 lb.ft)

14. Install the auto tensioner.

Leave the set pin installed in the auto tensioner.

If the auto tensioner rod is in its fully extended position, reset it as follows.

1. Clamp it in a vise equipped with soft jaws, in a level position. Use a plain washer if there is a plug at the bottom of the auto tensioner.

2. Compress the rod slowly with the vise until the set hole in the rod is aligned with set hole in the cylinder.

3. Insert a set pin through the auto tensioner body and rod.

Leave the set pin installed in the auto tensioner.

15. Install the tensioner pulley onto the tensioner arm.

Tightening torque
Tensioner pulley
43 ~ 55 N.m (430 ~ 550 kg.cm, 31 ~ 40 lb.ft)

16. Rotate the camshaft sprockets so that the dowel pin of the camshaft sprocket is at the upper side. Set the timing mark of sprocket correctly.

1. Before installing the timing belt, if the timing mark of the cam sprocket doesn't coincide with that of the rocker cover, do not rotate the cam sprocket more than 2 teeth of the sprocket in any direction.
Rotating the sprocket more than 2 teeth may make the valve and piston touch each other.
2. If it is necessary to rotate the cam sprocket more than 2 teeth, rotate the crank sprocket counter clock wise first based on the timing mark.
After the cam sprocket is properly timed return the crankshaft to TDC.

3. When exhaust and intake camshaft sprocket is used and install it after checking I.D mark depending on the engine deplacemeat.

17. Align the timing mark on each sprocket with the corresponding timing mark and install the belt as the following order.
Crankshaft sprocket - Oil pump sprocket - ldler pulley - Exhaust camshaft sprocket - Intake camshaft sprocket -Tensioner pulley

1. Be sure that the piston of NO.1 cylinder is located in TDC position (Compression storke).

2. When aligning the timing mark on oil pump sprocket, remove the left plug of cylinder block, and then check that the count balance shaft is in the specified position by inserting the screwdriver (Diameter : 8mm, insertinglength : 60mm or more)

3. After checking the timing mark, install the left plug of cylinder block.
Tightening torque : 2.7 ~ 3.4 kgf.m
(Apply the liquid gasket : THREE BOND NO.1212B or equivalent)

18. Pull out the set pin.

19. Rotate the crankshaft two turns clockwise and leave it for about 5 minutes. Then, measure the auto tensioner protrusion "A" (Distance between the tensioner arm and auto tensioner body) to ensure that it is within the specification.

Standard value : 5.5 ~ 9 mm (0.22 ~ 0.35 in)

20. Install the timing belt lower cover and the timing belt upper cover.

INSPECTION
Sprockets, Tensioner Pulley and Idler Pulley

1. Check the camshaft sprocket, crankshaft sprocket, tensioner pulley and idler pulley for abnormal wear, cracks or damage. Replace if necessary.

2. Inspect the tensioner pulley and the idler pulley for easy and smooth rotation and check for play or noise. Replace if necessary.

3. Replace the pulley if there is a grease leak from its bearing.

Auto Tensioner1. Check the auto tensioner for leaking and replace if necessary.
2. Check the rod end for wear or damage and replace if necessary.

3. Measure the rod protrusion. If it is out of specification, replace the auto tensioner.

Standard value : 14.5 mm (0.57 in)

4. Using a soft jaw vise , compress the auto tensioner rod. slowly. If the rod can be easily retracted, replace the auto tensioner. You should feel extensive resistance when pushing the rod in. And it must be compressed in sereral steps.

Clamp the auto tensioner in the vise so that it is level. Use soft jaws in the vise to avoid damaging the auto tensioner.

Timing Belt
1. Check the belt for oil or dust deposit. Replace if necessary. Small deposits should be wiped away with a dry cloth or paper. Do not clean with solvent.
2. When the engine is overhauled or belt tension is adjusted, check the belt carefully. If any of the following flaws are evident, replace the belt with a new one.
