1.3L petrol engine up to 7/84, 1.6L petrol engine designated 4A-L, 4A-F, 4A-FE
Attention: Removing the diesel timing belt, look here.
Removing
Remove the cover in the right wheel housing.
Remove spark plugs.
Remove V-belt.
Turn the crankshaft until the marking on the camshaft wheel matches the marking "0" on the timing cover, see fig. G-1018.
To rotate the crankshaft, engage fifth gear and move the vehicle on a level surface. You can also turn the crankshaft in another way. To do this, lift one of the front wheels, engage fifth gear and turn the wheel by hand.
Loosen the cylinder head cover bolts and remove the cover.
Check if the rocker arms of the valves of the first cylinder are pressed by the camshaft lobes. If pressed, the crankshaft must be rotated a full turn.
Loosen the crankshaft pulley screws. To prevent crankshaft rotation, use tools SST 09213-14010 and SST 09330-00020. If these tools are not available, engage first gear and, with the help of an assistant, press the brake pedal, thus blocking the engine.
Remove the crankshaft pulley. To do this, you can use the special tool SST 09213-31021. If the specified tool is not available, then the pulley can be removed with a universal puller, for example, HAZET 787N-16.
Attention: Before removing the pulley, put the gearbox in neutral and check again if the markings on the crankshaft pulley and the cover match. If the markings match, do not change the position of the crankshaft again.
Remove the top, middle and bottom timing belt covers.
Remove the crankshaft sprocket guide.
If an old belt is to be used, it must be marked as shown in the figure. To do this, an arrow is applied to the belt, for example with a felt-tip pen, indicating the direction of rotation of the belt. The motor rotates in a clockwise direction. Markings are also applied to the crankshaft and camshaft gears and their corresponding points on the toothed belt, as shown in the figure.
Loosen the idler pulley bolt. Press tensioning roller 1 in direction of arrow as far as it will go and tighten bolt again.
Remove the toothed belt, then do not change the position of the gears.
Installation
Caution: Do not kink or twist the toothed belt. A dirty and damaged belt should be replaced. Check the tension roller for ease and uniformity of movement.
Attention: If the camshaft turns with the toothed belt removed, make sure that the pistons are not in the UMT. Otherwise, it may cause damage to the pistons and valves.
If it becomes necessary to rotate the camshaft, first set the pistons to the middle height position. To do this, mark with chalk on the top of the crankshaft wheel (the piston of the first cylinder must be set to TDC). Then rotate the crankshaft wheel to the right or left 1/2 turn. In this case, the marking will point to the right or left.
Put on the toothed belt. If an old belt is installed, then it is necessary to take into account the direction of its rotation.
Attention: When installing a toothed belt, do not change the position of the crankshaft and camshaft. Otherwise, serious engine damage or loss of engine power may result.
Check if the camshaft is in the position corresponding to the TDC of the piston of the first cylinder. To do this, the hole in the camshaft wheel must match the markings on the bearing cap.
At the same time, the marking on the crankshaft sprocket must match the marking on the oil pump housing. In this case, the piston of the first cylinder is at TDC.
Remove bolt securing tensioning roller 1 and press against toothed belt.
Rotate the crankshaft twice in the direction of engine rotation and check the markings again.
Tighten the idler pulley bolt to 37 Nm.
Turn the crankshaft twice in the direction of engine rotation and check the adjustment again.
If the toothed belt tension is adjusted correctly, then the belt should bend 5-6 mm between the gears of the camshaft and crankshaft with a force of 20 N (about 2 kg), which corresponds to a slight pressure of the thumb.
Install the crankshaft wheel guide.
Reinstall the timing gear cover and secure it with bolts.
Install the key on the crankshaft. To facilitate the installation of the pulley, install the key so that it is sunk slightly more in front than in the back.
Lubricate the head and threads of the pulley bolt with a thin layer of engine oil.
Install the crankshaft pulley, using a pipe to fit it if necessary. Clamp the pulley with tool SST 09213-14010 and tighten the bolt to 120 Nm. If these tools are not available, engage first gear and, with the help of an assistant, press the brake pedal, thus blocking the engine.
Install the cylinder head cover.
Put on the V-belt and tension it.
Install spark plugs.
Bolt the cover to the right wheel housing.
