Checking the technical condition of timing drive parts
Sprockets, pulley
Check the camshaft and crankshaft sprocket, tensioner pulley and roller for wear, damage. Replace parts if necessary
Check the tensioner and pulley by gently turning them for noise. Replace parts if necessary.
If there is an oil leak from the bearing, replace the tensioner and roller if necessary.
Drive Belt
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 visibly damaged, replace it.
Do not bend, twist or rotate the belt inwards.
Keep water, oil, etc. out of the way. on the belt.
Removing the timing belt
Remove the engine cover (A).
Remove the front right wheel with tire.
Remove the wheel cover.
Remove the drive belt (A), pulley (B) and tensioner (C).
While removing the drive belt, fix the auto-tensioner pulley bolt with the special tool and turn 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 mark on the camshaft sprocket matches the mark on the cylinder head cover (cylinder No. 1 / TDC).
Remove the engine mount.
Install a jack to support the engine.
Install a wooden block between the jack and the oil pan.
Remove the engine mount bracket (A).
Remove the crankshaft pulley (A).
Remove the lower drive belt cover (A).
Remove engine mount bracket
After removal, there may be a slight leakage of coolant at the location indicated in the figure (B).
Remove the drive belt auto-tensioner (A).
Remove the drive belt (A).
mark the order in which the drive belt is removed.
Remove tensioner arm assembly (A) and pulley (B).
Remove the crankshaft sprocket
Installing the timing belt
Install the crankshaft gear.
Install 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 row exhaust camshaft sprocket (C) ► Water pump pulley (D) ►1st row exhaust camshaft sprocket (E) ► Tensioner pulley (F).
Install the timing belt tensioner.
Do not install tensioner within 5 minutes.
Press on the rod weighing 150 - 200 N.
If the stem does not move, smoothly insert the setting pin.
If the stem moves, push it 2 - 3 times so that the length is 2.9 mm (from the place where the 2 holes of the stem and body were at the same level).
Check stiffness.
If the rod does not move, insert a pin, replace the auto-tensioner.
Do not release the auto-tensioner.
Do not press hard on the stem. Press on the stem with a force of less than 4000 N.
Make sure the auto-tensioner is in the correct position.
In winter, store the autotensioner indoors.
Remove the auto-tensioner pin.
Check belt tension.
Turn the crankshaft 2 turns clockwise and set the first cylinder to TDC.
After 5 minutes, measure the stem length. Standard value: 5 - 7 mm.
Check the location of each asterisk label.
Install the engine mount bracket (A). Tightening torque: 58.8 ~ 68.6 Nm.
Check bolt length.
Only use a key with a torque limit.
Install the lower drive belt cover. Tightening torque: 9.8 ~ 11.8 Nm.
Move slightly to the left of the bolt hole by pushing the left drive belt cover.
Install the crankshaft pulley (A). Tightening torque: 166.7 ~ 176.5 Nm.
Install the engine mount 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 front right wheel and tire.
Install the engine cover (A). Tightening torque: 7.8 ~ 11.8 Nm.
