How to expose timing marks on VAZ-2109 and how often to change the belt?

On how to expose timing marks on the VAZ-2109, you need to know all the users of this car. Unfortunately, despite the high quality of the belts, they are torn quite often. And not on all nines the break is painless, on some engines the valves bend. Carefully study the entire process of replacing the belt, in case of a breakdown, repair yourself. Unfortunately, the timing belt does not ask permission for you to tear. And only a timely replacement for a quality belt, as well as installing all the labels, will help you avoid unscheduled repairs.

When is it necessary to change the timing belt?

If you refer to the manual, then there is a period of 60 thousand km. But this is only if the new "nine". The VAZ of this model has long been discontinued, so it will be better for you if you reduce the frequency of replacement to 40-45 thousand kilometers. The fact is that all engine mechanisms are gradually wearing out, deteriorating, which affects the proper functioning of the systems.

A timing belt - this is the element that is responsible for ensuring that the crankshaft and camshaft work as synchronously as possible. Simultaneously with the belt, the roller is replaced. You should also inspect the pump. It has a resource of 90 thousand kilometers. Therefore, it should change with each second belt, and how to expose the timing mark on the VAZ-2109 during repair, will be described below. In this way, you will ensure the planned repair of all the units that are in the drive structure. Unplanned replacement of the belt is made only in the event of its breakage or jamming of the pump, roller.

Preparing to replace the belt

Before you make a change, you need to take a few steps. Partial disassembly is required. First, remove the generator belt. To do this simply, just loosen the upper nut on the bracket. After this, the generator moves towards the ICE, the belt tension is reduced, it can be easily removed. Before you put the timing mark on the VAZ-2109, you need to remove the protective cover from the plastic. It is fixed to the block using three bolts.

Now loosen the wheel bolts and lift the right side on the jack. Do not forget that under the left rear wheel you need to put two stops. To be true, you can even squeeze the handbrake. If there is protection, then it must also be dismantled so that it does not interfere. The final touch is the twisting of the pulley bolt. On carburetor cars it is easy to keep it from scrolling. On the injector will have a strong screwdriver to rest against the teeth of the flywheel crown so that the timing belt timing marks match.

Removing the belt, installing a new one

Now that the generator drive pulley is off, and the timing belt is open, you can start dismantling it. Complicated in this action is nothing, key on the 17 twist the nut, which is attached to the roller. When it loosens, the belt tension will decrease. It is easily removed - first from the camshaft, then from the crank pulley. Here is where the most interesting begins - the installation of VRM timing marks. However, if you do not crank the shafts, you can simply install a new belt. But you still need to check.

Look at the camshaft pulley. On it there is a depression closer to the outer diameter. This is a mark that must be aligned with the bar, which is bolted to the engine block from the side of the cabin. Turn the camshaft clockwise until you combine these incisions. Now look at the crankshaft pulley, it is possible that it will be sufficient to combine only marks on it, because it's a "nine". VAZ has provided for installation the drilled deepening which is combined with a label on the block. But it is better, if the crankshaft is established on marks on a flywheel - to look it is necessary through the window located in картере couplings. By combining a long mark on the flywheel with a slot in the plate, you will ensure maximum synchronization of the shafts.

conclusions

Enough of a short excursion to learn how to expose the timing mark on the VAZ-2109. In this there is nothing difficult, if there is at least a couple of keys, a jack and good eyesight. However, it will be much more convenient if you have a flashlight and a key for a tension roller. But if there is no last one, then you can use two bolts and a screwdriver. The whole assembly consists in the fact that a new belt is installed, the belt is stretched so that in its longest free plane its maximum rotation is no more than 90 degrees around its axis.
