Timing Belt Mounting Elements
1 - toothed camshaft drive belt; 2 - disk; 3 - lower cover of the toothed belt; 4 - Power steering pump mounting bracket; 3 - Engine support bracket; 6 - generator adjustment mechanism; 7 - Power steering hose mounting bracket; 8 - Upper toothed belt cover; 9 - Timing belt tension roller; 10 - tensioning device.
Removal
Disconnect the ground cable from the battery.
Remove the lower protective cover.
Remove the engine mount bracket and crankshaft pulley.
After unscrewing the bolt, remove the power steering hose mounting bracket.
Remove the power steering hose clamp.
After unscrewing the bolts, remove the generator adjusting bar.
Remove the upper and lower camshaft drive belt covers.
Remove the roller disc.
After unscrewing the bolts, remove the power steering pump mounting bracket.
Remove the engine mount bracket.
Turn the crankshaft and align the timing marks (1) as shown in the figure.
After loosening the center bolt of the tensioner roller, remove the camshaft drive belt.
CAUTION: If the timing belt is reused, an arrow must be placed on the back of the belt to indicate the direction of rotation.
Location of the timing belt on the toothed wheels/rollers
1 - crankshaft gear; 2 - tensioner roller; 3 - camshaft gears; 4 - idler pulley; 5 - toothed wheel of the coolant pump.
Installation
Installation is carried out in reverse order, taking into account the following:
Apply a force of 100 N to 200 N to the automatic tensioner rod and measure the rod stroke, which should be no more than 1 mm.
If the amount of movement does not meet the required value, replace the automatic tensioner.
Place the automatic tensioner in a vice as shown in the figure and carefully, so as not to damage the push rod, squeeze the automatic tensioner until hole A is aligned with hole B.
Insert the locating pin (1) into the aligned holes.
Install the automatic tensioner on the engine.
Align the timing marks (1) on the camshaft gears (A) and crankshaft (B) with the corresponding pointers.
Loosen the center bolt securing the tensioner roller.
Turn the crankshaft pulley half a tooth counterclockwise.
Place the drive belt on the exhaust camshaft sprocket and secure the drive belt on this sprocket using the clamp (1) as shown in the figure.
Place the drive belt on the intake camshaft sprocket.
Align the alignment marks (1) as shown in the figure.
Secure the drive belt to the other sprocket with another clamp as shown in the figure.
Place the toothed belt sequentially on the guide roller, coolant pump drive wheel, crankshaft wheel, tensioner roller and remove the clamps.
Move the tensioner roller in the direction of the arrow and tighten the mounting bolt.
Make sure all alignment marks remain aligned.
Adjust the camshaft drive belt tension by turning the crankshaft 1/4 turn counterclockwise and then returning it to its original position, making sure that all timing marks are aligned.
Loosen the bolt (1) of the tensioner roller (4) and, using the special tool (3) inserted into the hole (2) and a torque wrench, tighten the timing belt, then tighten the bolt to a torque of 2.5-4.0 Nm.
Remove the locating pin (1) from the automatic tensioner.
Turn the crankshaft clockwise 2 turns then wait for 5 minutes, then check that the adjusting pin can also be easily inserted into the hole of the automatic tensioner and pulled out again.
The protrusion of the rod (A) from the tensioner should be within 3.8-4.5 mm.
If the protrusion value (A) corresponds to the required value, repeat the belt tensioning operations. Make sure that all the timing marks are aligned.
Install the roller discs.
Install the lower guard, engine mount bracket and crankshaft pulley.
