Camshaft oil seal size VAZ 2112 16 valves

We change the camshaft oil seal on a 16 valve VAZ-2112 with our own hands

The element of the camshaft that is very often subjected to constant loads and most often fails is the oil seal, or as it is also called the cuff. On a VAZ-2112, you can replace the oil seal with your own hands, since no special skills are required for this.

The video describes the replacement of oil seals on a 124 engine when replacing the timing belt.

Evaluation of results

The effectiveness of replacing camshaft seals is assessed after the mechanism is fully assembled and sea trials are carried out. In the area of the replaced part, even when the engine is running at high speeds, there should be no oil leaks or signs of sweating. If such phenomena occur, it means that the element was pressed incorrectly or had manufacturing defects.

Step-by-step work order

Before you begin, make sure that the car is on a level surface, the handbrake is on, and the negative cable on the battery is removed.

Removing the seals

First of all, open the hood and remove all the plastic elements. This applies to protecting the timing belt and engine lining.

If the bolts are not corroded, they will unscrew easily

Next, a dilemma may arise about whether to carry out the replacement without removing the cylinder head and dismantling the cylinder head. If you chose the second option, then the procedure for removing the cylinder head is written in great detail in this article.

If the first option is still closer to you, then we perform the following procedure:

Since the oil seals on the engine are located directly behind the camshaft pulleys, there is no escape from dismantling them.
Next, you need to arm yourself with a special puller, but if you don’t have one, then a regular flat-blade screwdriver will do.
Using a screwdriver, slowly remove the special key from the groove on the shaft.

The location of the key is indicated by the arrow

Please note that the key must be put in a safe place so as not to lose it.

Then, we carefully remove the oil seal, first from one side and then from the other.

Be careful not to damage the shaft itself

Installing camshaft seals

Before you begin installing new cuffs, check its condition by inspecting its working edge, which should not have any defects; it should be smooth without visible damage to the rubber. This also applies to the oil seal spring; it must be intact and there must be no signs of stretching or other visible damage.

The edge under the number is 1. and the spring under the number is 2.

Installation procedure

Before installing the oil seal on the camshaft, lubricate its lip with engine oil.

When the oil seal is on, it will easily pass through the body

Tapping should not be strong, but frequent

When installing the belt, follow all rules and requirements for aligning all marks.

Why is a second pump needed in a car's design?

On some modern car models, a second pump is already installed from the factory. This equipment allows for the most reliable engine cooling under any load.

An additional pump on the car is required to create better cooling. If we talk about the owners of the tenth family of VAZs, then most often a second pump is installed to optimize the operation of the stove in winter.

Installing an additional water pump

The main advantage of the VAZ 2110/2112 is that the cars have a simple cooling system structure. Therefore, you can install a second pump and organize a small circle of antifreeze circulation without any problems. To work you need to prepare in advance:

new pump;
two hoses (one long, the other short);
sealant;
fastening elements (depending on where it will be easier to attach the pump: metal clamps, bolts and nuts).

It is necessary to assemble a low circulation unit from a new pump and hoses. To do this, two hoses are connected to the pump fittings and secured with clamps.

It is important to follow the rule: the long pipe is responsible for supplying antifreeze to the pump, and the short pipe is responsible for draining it.

Before installing a new unit on the machine, you need to drain the coolant.

The installation procedure for the assembled unit is as follows:

Find two hoses near the cooling radiator (one of them supplies antifreeze to the stove, and the other performs a discharge function).
Disconnect the outlet pipe.
In its place, attach the assembled unit with the second pump.
Securely secure the new assembly with metal clamps.
It is recommended to attach the pump itself to the gearbox housing. You can secure the pump with clamps or bolt it to the bracket.
Fill with coolant and start the engine.
Check the second antifreeze circulation circuit for leaks.

It should be noted that the additional pump will be started under the influence of the pressure created in the system by the first pump. Therefore, the second pump will last a long time and ensure thorough cooling of the engine even under the most aggressive operating conditions.

Thus, the whole difficulty of repairing and replacing the water pump on a VAZ 2110/2112 comes down to correctly removing the unit from the car and installing it back. Moreover, installing the pump takes much longer due to changing the timing belt and roller. The services of a specialist will cost approximately 1000–1500 rubles, so if you have doubts about your competence, it is better to pay the service station technicians and be confident that the water pump will be replaced correctly.

Why is it necessary to replace on time?

On the left is the new seal, and on the right is the old one

It will be no secret to anyone that timely replacement of the camshaft oil seal will not harm the engine in any way, but will only increase its performance characteristics. The time period for replacing it is not determined in any way and depends only on the mileage and driving style. Since frequent and intensive use of the engine leads to rapid wear of all these parts.

Timely replacement of the oil seal will prevent oil leakage from the engine, which is its main task.

However, if this moment was missed, and a leak did occur, this will be accompanied by very unpleasant facts:

Oil consumption will increase.
The engine will be constantly dirty , since dust from the road will constantly stick to the oil that spills onto the engine.
Also, oil that leaks from the engine will negatively affect the general condition of various electrical contacts and elements. First of all, this applies to electrical power supply blocks, where contact may be deteriorated.

Benefit of the cuff

If the oil seal (cuff) fails or, simply, leaks oil, this significantly affects the operation of the car:

the most minimal harm is that on the VAZ 2110 the engine and the entire engine compartment will be oily; importantly, oil consumption will increase, it will have to be constantly topped up, which the oil level sensor will constantly remind you of; when the oil level drops, valve knocking will be heard, and they are more likely to fail; oily non-metallic parts in a car are quickly destroyed; Oily contacts lead to many problems, starting with poor engine starting; Since problems may arise with the quality of camshaft lubrication, its position (phase) sensor may also malfunction. At the same time, fuel consumption increases, since there will be no adjustment of the fuel supply to each individual cylinder, and the load will be the same for all valves.

Oil seals

What is an oil seal? This page showed oil seals by size for VAZ cars and catalog numbers, role and purpose...

Greetings to all readers on the RtiIvaz.ru blog. The page shows photographs of crankshaft oil seals as a set for the gearbox of a family of classic rear-wheel drive cars, as well as gearboxes of front-wheel drive eights and a dozen VAZs. The cuff of the rear gearbox, also called the rear axle, is installed in rear-wheel drive “Classic” cars.

In fact, there are many of them different in shape, size, and purpose. Some hold oil, antifreeze or antifreeze, others hold air, water pressure, all are designed to protect car parts from dirt, dust and other factors.

For example, the crankshaft seal and the camshaft keep oil from flowing between the joints of the camshaft journal and the seat of the engine block. The same role is played by the cuffs of the gearbox, gearbox, and axle shaft. The hub is protected from dirty water and dust from leaking antifreeze or antifreeze into the pump.

You can list the role of the purpose of car oil seals, I will only say one thing without them in our age of mechanical engineering. Someday they may disappear in a car, but this is already on the verge of fantasy when the car becomes something like a flying saucer “UFO”. In the meantime, we will think about these photo seals and where to use them.

Let's look at a photo of crankshaft cuffs for VAZ 2108 car engines; 2109; 2113; 2114; 2115; 2110; 2111; 2112; 2170; 1118 and 1111 "Oka".

The set includes three seals, two small and one large. Of the small ones, one goes to the front camshaft cover, the other small one goes to the front crankshaft of VAZ 2108 cars; 2109; 2113; 2114; 2115; 2112; 2115; 2170; 1118 and 1111 "Oka". The large rear one is located in the engine crankshaft on the clutch side.

Goodbye on the pages of the blog RtiIvaz.ru!

Functionality check

Before you start replacing the cuff, if you find traces of oil on the engine, you need to carry out several checks:

It is likely that the system responsible for ventilating the oil sump is clogged;
The hoses in the system may become pinched, causing a malfunction.

If checking these elements shows that everything is in order, you will have to replace the oil seal.

We advise you to pay attention to several important points.

Start the engine and listen for rattling valves or a loose camshaft making noise. A regular stethoscope will help you here, which will provide more accurate listening. It is likely that you will need to replace the cuffs and camshaft, or its components that are responsible for the knocking.
In some situations, knocking can be eliminated by simply replacing the timing belt.
Check the engine at idle speed. If the engine operation is unstable, or it is difficult to start the engine, check the condition of the camshaft position sensor. Sometimes replacing this element returns the motor to its previous operating efficiency.

About the oil seal

The oil seal is one of the most common and long-invented sealing devices for moving mechanisms. This part is widely used due to its simple design.

It should be noted that the oil seals used in VAZ cars have a direction and need to be installed only in the designated direction of shaft rotation.

Device

The oil seal is made of special rubber, which does not lose its properties when in contact with oil. This kind of rubber is called oil-resistant .

Structurally, the oil seal is similar to a ring; inside the oil seal there is a so-called “box”. Which, under the influence of oil pressure, is pressed against the working part of the shaft and creates a tight seal.

The oil seal also has a spring that presses its working part against the shaft ensuring tightness.

Causes of malfunctions

The main cause of the malfunction is simple mechanical wear. Any oil seal is, by its nature, a consumable - after a certain period of time it begins to deteriorate, since it is made of an elastic material.

The malfunction may manifest itself in the form of changes in shape, swelling, scarring, rupture or chipping of the material from which the consumable is made. Another manifestation of a malfunction may be the cuff being completely squeezed out of the seat.

Other causes of problems with the camshaft oil seal are incorrect selection of consumables, manufacturing defects, or incorrect installation. In these cases, the oil seal also does not perform its functions and needs to be replaced.

This is interesting: Malfunctions of the exhaust system of VAZ 2110/2112. Muffler replacement

Dimensions of the oil seal distributed by VAZ

The dimensions of the oil seal installed on the camshaft of VAZ cars are the same only for front-wheel drive Lada cars. It should also be noted that the dimensions of the oil seal do not differ depending on the type of engine, that is, if the engine has 16 valves, then the oil seals for each camshaft will be the same.

Oil seal size: 28*42*7

How to tighten main bearings and connecting rod bearings

So, taking into account the above, it becomes clear that the tightening torque of the main and connecting rod bearings is extremely important. Now let's move on to the assembly process itself.

First of all, molar liners are installed in the bed of the molar necks. Please note that the middle liner is different from the others. Before installing the bearings, the preservative lubricant is removed, after which a little motor oil is applied to the surface. After this, the bed covers are placed, after which the tightening is carried out. The tightening torque should be that recommended for the specific model of the power unit. For example, for engines on the VAZ 2108 model, this figure can be from 68 to 84 Nm.
Next, the connecting rod bearings are installed. During assembly, it is necessary to accurately install the covers in place. The specified covers are marked, that is, their arbitrary installation is not allowed. The tightening torque of the connecting rod bearings is slightly less compared to the main bearings (the indicator ranges from 43 to 53 Nm). For Lada Priora, the main bearings are tightened with a torque of 68.31-84.38, and the connecting rod bearings have a tightening torque of 43.3-53.5.

Where is

The oil seal is located under the timing belt boot, behind the camshaft gear.

The oil seal must be replaced if engine oil leaks through it. This leak can lead to oil getting onto the timing belt, which is strictly prohibited. Oil can damage the belt and lead to its breakage, which on 16-valve engines can lead to valve bending.

List of tools

To replace the camshaft oil seal on VAZ-2110 and 2112 16 valves, a minimum set of tools is required. These include:

key to “10”;
key to "17";
Slotted screwdriver;
Mandrel for pressing;
A small amount of motor oil.

A pit or lift is not required for manipulation. The unit is fully accessible from the engine compartment. On VAZ-2110 cars there are 8 valves and on 16 valve units the oil seal is located under the camshaft pulley, on the right side in the direction of movement of the car.

Replacing the oil seal

The replacement process is simple, but quite long. To carry out the work, it is necessary to remove the timing belt and camshaft gears, and in models with a 16-valve engine, it is necessary to remove the timing rollers and the rear part of the timing boot cover.

Required tool:

Step-by-step replacement instructions

The first thing you need to do is remove the timing belt. How to do this can be studied in detail in our article “Replacing the Timing Belt”. It is first recommended to loosen the camshaft pulley mounting bolt with a 17mm wrench, since this will be much more difficult to do after removing the belt.

We wipe the seat and shaft from debris.

We install a new oil seal, lubricating the shaft with clean engine oil. This will ensure easier sliding and movement of the oil seal along the shaft.

As a mandrel, you can use the head from the tool kit; you need to select the head in such a way that part of it rests against the metal part of the oil seal, but not against the working part.

Using a hammer, lightly install the oil seal into its place.

The replacement is completed, we carry out the assembly process in reverse order.

conclusions

As you can see for yourself, there is nothing complicated about replacing the camshaft oil seal on a VAZ-2112. This work is not primitive, but does not require any special skills. You just need to carefully read this and all the supporting articles and then the repair will not become something unusual for you. After all, by doing such work yourself, you not only save your budget, but also significantly increase your experience in repairing your own car.

If you find traces of oil leakage through the camshaft seals, first check to see if the crankcase ventilation system is clogged and if its hoses are pinched, and if necessary, repair the faults.

If the oil leak does not stop, replace the seals.

Using a 10mm socket, unscrew the six bolts securing the front cover.

Removing the front cover

Using a 17mm spanner, loosen the bolt securing the exhaust camshaft toothed pulley.

By inserting a screwdriver into the pulley hole, we hold it from turning.

In the same way, loosen the bolt of the intake camshaft toothed pulley.

Oil seal catalog number – 2112-1006216

After unscrewing the fastening bolts, remove the camshaft pulleys.

Use a screwdriver to pry up the seals and remove them.

Lubricate the working edge of the oil seal with engine oil.

We press in new oil seals with a suitable piece of pipe

We assemble the timing drive in reverse order.

Consequences of oil getting into spark plug wells

When oil appears in the spark plug wells, soot will appear on the spark plugs, high-voltage wires will break through, and the engine will constantly stall or may not start.

Structurally, it so happened that only 16-valve engines with a volume of 1.6 liters are equipped with spark plug wells. For the 1.5 engine, guide tubes are installed - glasses that are missing on the older brother. This can be determined very simply:

We unscrew the candle.
Visually inspect the nest.
If the surface is smooth, then glasses are installed, and if there are slits, then spark plug wells are installed.

We change the camshaft oil seal on a 16 valve VAZ-2112 with our own hands

The video describes the replacement of oil seals on a 124 engine when replacing the timing belt.

Very useful recommendations

We recommend not pouring diesel oil (as amateurs advise) into a gasoline engine; a thick sediment will appear in it, which will lead to blockage of all oil channels of the engine.

This work requires some skills from you, if you are already familiar with the structure of the motor and the tools, and are not afraid to disassemble the engine yourself, then strictly following our useful tips, you will be able to replace the valve seals with your own hands.

To replace, you will need a new set of valve stem seals (see VAZ 2106: replacing valve stem seals on your own), which we recommend ordering from a store specializing in spare parts or purchasing immediately; the caps are in stock.

Ask: Why in a specialty store? Because, having experience, we have made the following conclusion - a specialized store is interested in a good reputation and, in principle, will not sell “inappropriate” or obviously low-quality goods.

In any auto market, the choice of caps is much wider, sometimes sellers have no idea who the manufacturer of the product is, so don’t expect any guarantee of quality in this case. It is reliably known that the bulk of cheap spare parts on the auto market today are imported from China.

In a specialized spare parts store, the seller can determine by computer, by entering the code in your data sheet, the engine model, based on this data, and select the necessary (suitable) valve seals.

Step-by-step work order

Before you begin, make sure that the car is on a level surface, the handbrake is on, and the negative cable on the battery is removed.

Removing the seals

First of all, open the hood and remove all the plastic elements. This applies to protecting the timing belt and engine lining.

If the bolts are not corroded, they will unscrew easily

If the first option is still closer to you, then we perform the following procedure:

Since the oil seals on the engine are located directly behind the camshaft pulleys, there is no escape from dismantling them.
Next, you need to arm yourself with a special puller, but if you don’t have one, then a regular flat-blade screwdriver will do.
Using a screwdriver, slowly remove the special key from the groove on the shaft.

The location of the key is indicated by the arrow

Please note that the key must be put in a safe place so as not to lose it.

Then, we carefully remove the oil seal, first from one side and then from the other.

Be careful not to damage the shaft itself

Installing camshaft seals

The edge under the number is 1. and the spring under the number is 2.

Installation procedure

Before installing the oil seal on the camshaft, lubricate its lip with engine oil.

When the oil seal is on, it will easily pass through the body

Tapping should not be strong, but frequent

When installing the belt, follow all rules and requirements for aligning all marks.

Camshaft: purpose and functions

With the help of the camshaft, the intake and exhaust strokes of the internal combustion engine are synchronized.

The gas distribution mechanism (GRM) has a lower and upper arrangement of valves in the cylinder block, it all depends on the type of engine in your car. Manufacturers of modern cars prefer a timing belt with valves located at the top. This design makes it possible to carry out repair work and maintenance of the camshaft without any problems, because access to the timing elements is quite simplified.

The camshaft and crankshaft of the power unit are structurally interconnected. The connection is made using a belt or chain, which is put on the camshaft pulley and the crankshaft sprocket. The camshaft is driven by the crankshaft.

Probably the most effective camshaft pulley is the split gear, used in camshaft tuning to increase engine power.

Why is it necessary to replace on time?

On the left is the new seal, and on the right is the old one

Timely replacement of the oil seal will prevent oil leakage from the engine, which is its main task.

However, if this moment was missed, and a leak did occur, this will be accompanied by very unpleasant facts:

Oil consumption will increase.
The engine will be constantly dirty , since dust from the road will constantly stick to the oil that spills onto the engine.
Also, oil that leaks from the engine will negatively affect the general condition of various electrical contacts and elements. First of all, this applies to electrical power supply blocks, where contact may be deteriorated.

Selection of parts for tuning an 8 valve engine

Before tampering with the engine, it is necessary to accurately determine:

There are about a dozen different types of camshafts, with significant differences in characteristics. Eg:

In other words, we can say that there are three main types of camshaft designs:

“low-level” (increased power at the “lower” levels from 1200 rpm)
“civilian” (average version)
“main” (sport mode, increase at the “top”)

According to the laws of physics, it is impossible to achieve the same increase in all modes, so you should immediately decide on the type of camshaft.

Practice shows that for quiet driving around the city, with the possibility of saving fuel, a “low-level” camshaft is most suitable. For city-highway traffic, it is better to choose the middle option; for highway drivers, the “highway” option is more suitable.

To achieve maximum effect, you should immediately install a split timing camshaft drive gear.
