Checking the technical condition of timing drive parts
Check the camshaft and crankshaft sprocket, tensioner pulley and roller for wear and damage
Replace parts if necessary
Check the tensioner and roller, turning them smoothly for noise. Replace parts if necessary.
If there is an oil leak from the bearing, replace the tensioner and roller if necessary.
Check the belt for oil or dust build-up.
Replace the belt if necessary.
Dust should be wiped off with a dry cloth. Do not clean the belt with solvent.
Carefully check the belt when the engine is disassembled or the tensioner is replaced.
If the belt is clearly damaged, replace it.
Do not bend, twist or rotate the belt inward.
Keep away from water, oil, etc. on the belt.
Removing the timing belt
Remove the engine cover (A).
Remove the front right wheel and tire.
Remove the wheel cover.
Remove the drive belt (A), pulley (B) and tensioner (C).
When removing the drive belt, secure the auto tensioner pulley bolt with a special tool and turn it counterclockwise.
Remove the upper timing belt cover (A).
Align the pulley groove with the mark on the drive belt cover by turning the crankshaft clockwise.
Check that the camshaft sprocket mark matches the mark on the cylinder head cover (cylinder No. 1 /TDC).
Remove the engine mounting bracket.
Install a jack to support the engine.
Install a wooden block between the jack and the oil pan.
Remove the engine mounting bracket (A).
Remove the crankshaft pulley (A)
Remove the lower drive belt cover (A).
Remove the engine mount bracket (A).
After removal, there may be a slight leak of coolant in the area indicated in figure (B).
Remove the drive belt auto-tensioner (A).
Remove the drive belt (A).
mark the order of removing the drive belt.
Remove the tensioner arm assembly (A) and pulleys in (B).
Remove the crankshaft sprocket.
Installing the timing belt
Install the crankshaft gear.
Install the tensioner arm assembly (A) and pulley (B). Tightening torque:
- - tensioner lever: 34.3-53.9 Nm,
- - Pulley bolt: 49.0-58.8 Nm.
Align the marks on the camshaft and crankshaft sprockets.
Install the drive belt as follows: Crankshaft sprocket (A) ► pulley (B)
2nd Bank Exhaust Camshaft Sprocket (C) ► Water Pump Pulley (D) ► 1st Bank Exhaust Camshaft Sprocket (E) ► Tensioner Pulley (F).
Install the timing belt tensioner.
Do not install the tensioner for 5 minutes.
Press the rod weighing 150-200 N.
If the rod does not move, smoothly insert the adjusting pin.
If the rod moves, press it 2-3 times so that the length is 2.9 mm (from the place where the 2 holes of the rod and body were at the same level).
Check the rigidity. If the rod moves, insert a pin and replace the auto-tensioner.
Do not release the auto tensioner.
Do not press sharply on the rod. Press the rod with a force of less than 4000 N.
Make sure the auto-tensioner is installed in the correct position.
In winter, store the auto tensioner indoors.
Remove the auto-tensioner pin.
Check the belt tension.
Rotate the crankshaft 2 turns clockwise and set the first cylinder to TDC.
After 5 minutes, measure the length of the rod.
Standard value: 5-7 mm.
- Check the location of the marks of each star.
Install the engine mount bracket (A). Tightening torque: 58.8 ~ 68.6 Nm
Check the length of the bolts.
Use only a torque wrench.
Install the lower drive belt cover. Tightening torque: 9.8 ~ 11.8 Nm
Move slightly to the left of the bolt hole while pressing down on the left drive belt cover.
Install the crankshaft pulley (A). Tightening torque: 166.7 ~ 176.5 Nm.
Install the engine mounting bracket (A). Tightening torque: 63.7 ~ 83.4 Nm.
Install the upper drive belt cover (A). Tightening torque: 9.8 ~ 11.8 Nm
Install the belt tensioner (C). Tightening torque: 34.3 ~ 53.9 Nm.
Install the belt pulley and drive belt (A). Tightening torque: 34.3 ~ 53.9 Nm
Install the right cover.
Install the front right wheel and tire.
Install the engine cover (A). Tightening torque: 7.8 ~ 11.8 Nm.
