VAZ 2114: replacing the crankshaft oil seal (8 valves)

Necessary tool

Wear of the oil seal leads to oil leakage from the engine, which should not be allowed on any car. Replacing a part yourself is only possible if you have the tools and detailed instructions. Let's look at the tool needed for the job:

Set of wrenches and ratchets with heads. You will need open-end wrenches for 10, 13, 19;
New oil seal for installation;
Socket wrench;
Flat screwdriver;
Container for draining old oil;
New engine oil;
Sealant for a secure fit;
Oil pump gasket;
Jacks;
Hammer.

As you can see, for self-replacement you need a fairly extensive list of tools. Replacing the front crankshaft oil seal of a VAZ 2114 is similar to changing the rear element, so the set of tools to replace it will need the same.

In addition to jacks, you will need wheel chocks to lift the car. You should not use shifting into gear as a way to protect against the car rolling away. Understanding how to replace the crankshaft oil seal on a VAZ 2114 allows even an inexperienced car owner to carry out the work. First, let's look at the instructions with step-by-step actions for changing the front element.

Replacing the front crankshaft oil seal on a VAZ 2108 - detailed instructions

1. Remove the engine protection, if equipped.

2. Then - the timing belt cover.

3. Now you need to align the crankshaft according to the marks.

4. To remove the timing belt, you need to loosen it a little.

5. Install the jack and hang it up, remove the front right wheel.

7. Using screwdrivers, remove the crankshaft pulley.

8. Install the container and drain the oil from the pan.

9. Dismantle the pallet itself; to do this you will have to unscrew as many as 16 bolts.

10. Remove the oil receiver and perform a visual inspection to make sure it is not clogged anywhere. If necessary, blow out using compressed air.

11. Unscrew the 6 bolts securing the oil pump to the block, arrange them in the order of unscrewing, so as not to confuse which one was tightened where.

12. If there are “rags” left on the block from the old gasket, remove them.

13. Remove the old oil seal; finger pressure is usually sufficient.

14. Install a new oil seal; for this you can use a mandrel in the form of a head at “27”.

15. Before installing the oil pump, it is necessary to lubricate the edge of the oil seal with oil, and also lubricate the oil pump gasket with graphite grease.

16. Now install the oil pump on the crankshaft; it fits in only one position - along special guides.

17. Upon completion of installation, you must reassemble everything in the reverse order.

It is also better to lubricate the pan gasket, but not with oil, but with sealant. Then install the pan and fill in the oil, check its condition, it may be. How to tension the timing belt is written.

Having prepared the tools and spare parts, you can begin work on replacing the worn part. The step-by-step repair process looks like this:

Remove the protective plastic cover from the timing belt.
The next stage is setting the first cylinder of the engine to top dead center. This manipulation is carried out as follows: the camshaft and crankshaft are rotated until the marks on their pulleys coincide with the marks on the timing case cover.
To remove the timing belt, the front right wheel is jacked up and the engine protection is removed. Before tightening the belt, you need to loosen the tension. To make work easier, you can remove the fender liner and remove the alternator belt. After this, the crankshaft pulley itself is removed and the timing belt tension roller is loosened.
After removing the crankshaft pulley, drain the engine oil.
Remove the engine sump, which is secured with 16 bolts.
After removing the pan, you need to unscrew the oil receiver. After dismantling, check it for debris. Its channels can be cleaned with a compressor.
The next step is to remove the oil pump. This element is secured with six bolts.

A gasket is placed where the oil pump is attached to the engine block. Over time, it loses its properties, and when the part is removed, it is completely destroyed. During the reassembly process, do not forget to change this gasket.

Having completed dismantling the oil pump, you will have access to the front o-ring. You can pull it out with your fingers or a flat-head screwdriver.
After removing the old element, clean the surface and seat from oil and dirt. To install the new rubber ring tightly, you can use a 32mm socket socket. Having rested it against the new oil seal, apply a couple of firm blows and insert the rubber ring into the seat. Do not make strong blows, because... The ring is made of soft material.

When completing the installation, reassemble everything in reverse order and fill in with new engine oil. As a recommendation, we note the need to lubricate the internal surface of the part before installation. It is enough to lubricate the surface with a few drops of motor oil. In addition to the front sealing ring, the VAZ 2114 engine also has a rear sealing element. Next, we will consider the step-by-step replacement of the rear crankshaft oil seal of the VAZ 2114 (8 valves).

Step-by-step process for removing the rear oil seal

If no special experience is required when replacing the front oil seal, then to work with the rear oil seal, an assistant and a more thorough study of the technical component of the car may be required.

When carrying out such work, it is necessary to do all the above points from 1-12.
Next, you need to move on to dismantling the gearbox and clutch.
When the clutch is removed, unscrew the four bolts that secure the flywheel, and then remove it.
Then, when access to the oil seal is open, you can dismantle the housing in which it is located, or replace it directly in it.
We remove the sealing ring from the place where it is fixed.

We install the new part and perform the entire assembly in the reverse order.

Upon completion of assembly, start the engine and pay attention to the presence of oil leaks at the places where they are installed.

Replacing the rear oil seal

Changing this part is a little more difficult, because... Removal of the clutch kit and the entire gearbox assembly is required. For comfortable work you will need a lift or pit. The step-by-step replacement process looks like this:

To begin, dismantle the gearbox and clutch assembly.
Using the “17” head, unscrew the six bolts securing the flywheel.
We note the position of the flywheel relative to the crankshaft.
We remove the flywheel.
We remove the element from the landing site using a flat-head screwdriver.
Using the old oil seal as a mandrel, we insert the new element into the seating area with gentle blows of a hammer.
We align the flywheel according to the marks.
Lubricate the fastening bolts with sealant (their threaded part).
We assemble everything in reverse order.

As you can see from the instructions, it is possible to replace these parts with your own hands, but you will need tools, a lift or a pit. At the service, worn-out elements can be replaced for 1,500-2,000 rubles, which for some 2114 owners is quite an impressive amount.

Replacing the Crankshaft Oil Seal VAZ 2114 8 Valves

Replacing the front and rear crankshaft oil seals on a VAZ 2114 (8 valves) at home, LuxVAZ

The crankshaft seal is far from the most reliable in the design of any car. Therefore, its replacement with the 8-valve VAZ 2114 is carried out quite often.

Camshaft drive diagram

However, the procedure differs depending on the duration of the project in which a particular oil seal is located at the front or rear. We will talk about each of them separately.

2114 car you will need a small set of tools, where it goes:

10 mm socket head;
Wrench 10 mm;
Kernel;
Screwdriver.

Replacement work is carried out in the following order.

We disassembled the oil pump from the car. It is easy to do and can be done without the help of others.
Next, the cover of the same oil pump and the soft box
. Here you will need a narrow screwdriver, the device of which is responsible for assembly and removal.
The new element is pressed into place using a mandrel, the outer diameter of which should be about 41 mm. The working edge should be oriented inward.
The oil pump returns to its destination.

It must be said that the clutch discs are oily due to leakage from the soft box input shaft of the gearbox or through the rear crankshaft seal.

The smell of engine oil and transmission is different, so some experienced experts have different tastes to determine which item is causing the problem.

A visual determination method is being considered. To do this, take any container, pour some water into it, or just use a puddle near your garage. Monitor the behavior of oil leaking into the clutch discs into the water. If the oil spills and turns into a rainbow film, it is oil from the box. If the oil remains in the water as a granular droplet, it is motor lubricating water.

Replacing the rear oil seal is much more difficult than replacing the front one. However, this does not mean that working from home is any more realistic.

Following the annotations, we step by step change the crankshaft oil seal on a VAZ 2114

This will be a fairly common event for your company and will add the experience of doing your own car repair to your baggage.

VAZ 2115 replacing the camshaft oil seal

Disconnect the negative terminal from the battery of your VAZ 2114.
Record the position of the flywheel relative to the crankshaft, and then disassemble it.
The rear clutch housing guard is then removed from the guide bushings.
The next step is to remove the eight bolts that hold the seal in place.
This way you can remove the holder.
The oil seal is compressed from its own holder.
The new element is completely installed at the destination of the old one. Here again you will need a mandrel. Its outer diameter is 99 mm. Press the element so that it fits inside the working edge.
To make pressing easier, a chamfer is placed on the seating edge of the file. Another bevel tool is a small sanding wheel.
Now we are changing the gasket, which apparently broke on the holder. Even if the old gasket looks fine, we recommend replacing it with an old one.
The gasket is glued to the thick mixture with a special lubricant. This will ensure the strength of its retention, as well as additional tightness of the connection.
The working edge of the sealed oil seal is treated with ordinary motor oil in the same way as if it had a front passage.
The crankshaft flange undergoes a similar treatment.
The attachment of the engine oil compartment to the cylinder block should be slightly loosened. It is enough to make 2-3 turns on each of the 14 bolts that hold the crankcase.
When installing the holder, the working edge of the new oil seal is carefully screwed into the crankshaft flange. To do this, equip yourself with a wooden stick, but do not use iron objects.
Tighten the rear lock bolts.
Turn the engine casing bolts back.
Place the rear clutch housing back onto the guide bushings.
Install the flywheel, gearbox and clutch in place of the previously used seats. To ensure high quality flywheel mounting bolts and reliable fastening to the handle, first apply sealant to their threads.

Replacing the front oil seal on a VAZ 2113-VAZ 2115

Note!

Before replacing the oil seal, make sure that the problem is there and not caused by the crankcase ventilation system. It’s just that this system becomes dirty over time and oil begins to be squeezed out through the seals. We recommend that you read more about this topic in the article: “Cleaning the crankcase gas system on a VAZ 2114.”

Removal

First, you need to remove the timing belt from the pulleys (look for instructions in the publication: “Replacing the timing belt on VAZ vehicles”). Then, using two small screwdrivers, carefully pry off the crankshaft toothed pulley (photo 1). Behind you will find an oil seal; just pry it out with a screwdriver and remove it from its seat (photo 3). However, there is a metal key on the crankshaft (photo 2, indicated by the arrow). It is advisable to carefully pry it with a screwdriver and remove it, or make sure that it does not fall and get lost. The key keeps the pulley from turning; the part is important, so if you lose it, go to the auto store for a new part.)

Installation

The main thing is to lubricate the oil seal with the engine oil currently poured into the car engine. It is not the entire oil seal that needs to be lubricated, but only the working edge - the place where the oil seal sits on the shaft. Then take a small piece of pipe or a union head of a suitable diameter and, with their help, the oil seal is pressed inside (photo 4). After installation, thread the oil seal with a thin, but not too sharp, pencil. Check whether the part is installed well.

Note!

During installation, do not make the wrong side, otherwise the seal will leak. The oil seal has a front one with a spring, indicated by the letter B, and a rear one. The front one should be tucked inward, and the rear one should be directed outward.

2. After the work has been done, put the pulleys in place, the keys, and also install the timing belt. Adjust the belt tension using the tension pulley and start the car. First of all, pay attention to the place where you installed the oil seal - there should be no leaks. Add oil to the car engine up to the MAX mark, drive for a while, and see if the oil goes away quite quickly. No? This means the oil seal is installed correctly and nothing is leaking through it.

Note!

If after replacing the oil seal the leak does not stop, then either it was installed incorrectly or there is a problem in the lubrication system, because there is more pressure in it.

Additional video

We have attached video material on the topic of today's publication, we recommend that you read:

The VAZ-2114 manufacturer requires that replacing the front or rear crankshaft oil seal be carried out exclusively after removing the oil pump, which minimizes any risk of damage to parts located next to it. Therefore, you will need to find a garage with an inspection pit and drive your car into it, as well as prepare the following tools and accessories:

spare parts. In addition to the new crankshaft seal, you will also need to replace the oil pump gasket;
socket heads and open-end wrenches;
a basin for drained engine oil, as well as new lubricant, which will need to be filled in after installing the part;
hammer and flat blade screwdriver;
sealant.

You will also need a jack to remove the front wheel and gain access to the engine guard.

Where is?

To prevent lubricant from getting onto components outside the oil pan, there is an oil seal at the outlet holes through which the crankshaft is connected to other engine components. One of them is front, the other is rear. Their purpose is to ensure the tightness of the housing.

Crankshaft seals

The front one is located behind the crankshaft pulley on the oil pump. To replace the rear one, it is necessary to dismantle the gearbox, clutch and flywheel, then the rear cuff will be accessible. You can see this clearly in the video posted at the end of the article.
