How to replace the epiploon with your own hands?

When there is a leak in the area of the crankshaft oil seals (cuffs), the question arises about their replacement. Ignoring this breakdown, you can further exacerbate the problem. Oil leakage will become stronger with time, which will lead not only to the need to constantly top up it, but also to provoke the failure of the engine parts.

Causes of breakage

Often the epiploon of the root has a working resource equal to 150 thousand kilometers of run. But it may happen that it will be damaged before the deadline. There are several main reasons why radial cuffs, be it front or rear, can be damaged: engine overheating, application of inappropriate lubricants, engine operation without the timely replacement of oil and filter. The use of poor quality seal components also results in a leakage of the root gland. Regardless of the reason, the replacement of cuffs should not be postponed. Due to the fact that the front sealing element is more susceptible to external influences (dirt, moisture, dust) and vibration loads, it most often fails before its analog at the rear of the motor. But if the trouble happened only with the front seal, then change them in a pair, because their resource is the same. If the damage to the seal in the area of the pulley can be seen visually, then the second is slightly more difficult - you can not determine by eye. In general, when you wear it, you can see the fact of slipping clutch. This is due to the fact that its elements get oil from the crankcase.

Tools and accessories

To carry out the repair process you will need:

• A container for draining the oil from the crankcase;
• Rags;
• A set of curly and flat screwdrivers;
• A set of spanners (union, carob, head);
• Hammer and mandrels.

The entire replacement process can be performed independently, following the correct sequence of technological stages of repair work. Below are described the methods of dismantling and installation of new root cuffs using the example of VAZ's "nine".

We change the epiploon of the radical front

Initially, we install the machine on the inspection ditch or trestle and de-energize the on-board network by removing the negative terminal with the battery. Turn the drain plug off the engine tray and drain the oil. For easy access to engine parts, you can remove the front right-hand wheel. When the work is not carried out alone, in parallel, you can start dismantling the generator and its drive. Further, it is necessary to remove the plastic protective cover of the timing belt and start dismantling it, first loosening the tensioner mechanism. The crankcase must also be cleaned. It is important to say that after removing the timing belt, it is not recommended to turn the distributing and crankshafts, as this will require the need to re-set the timing and ignition timing. Therefore, to prevent this, it is desirable to include the first gear.

In the future we dismantle the crank from the crankshaft - unscrew the fastening bolt and tighten it using two screwdrivers. If the ratchet key is held firmly on the shaft, then it is also recommended to remove it. Then remove the oil receiver from the engine. To do this, unscrew the two bolts of its attachment to the bearing of the crankshaft bearing and one to the oil pump. Then we dismantle the oil pump by turning off the six bolts. Now we have access to the cuff. Using a powerful flat screwdriver, remove the engine radial seal from its seat in the pump cover.

Installation of a new radial sealant

Immediately before the installation of a new part, we carefully rinse the lid in gasoline and wipe it with rags. The seat of the cuff is pre-lubricated with a thin layer of motor oil. Observing the correct location of the stuffing box in the lid, install it in place. In addition, using a special mandrel, press the radial seal so that it seeps into the production hole. It is important not to damage the lip seal. Then it is necessary to proceed with mounting all the removed parts to the engine, observing the entire technological sequence of the process. Despite certain difficulties, it can still be done independently at home. Of course, it is more convenient to work with a partner.

Quick replacement

There is another, more rapid way to replace the lip seal. But he's a little risky. At the heart of the method is the absence of the need to remove the sump, oil sump and oil pump. The cuff changes directly on the engine. The disadvantage of this method is the inconvenience of carrying out the work. In addition, there is a possibility that the stuffing box will not be pressed enough into the oil pump cover. There is a risk of damage to the glossy coating of the crankshaft - accordingly, there is a possibility of occurrence of new leaks.

Advice of specialists

Such kind of spare parts for VAZ should be chosen with special attention and it is desirable only at official dealers. Otherwise, you can buy and install a substandard component on the car, which will lead to its rapid deterioration. In turn, this will entail certain additional time and financial costs.

We change the epiploon of the root back

Typically, the replacement of the back cuff is carried out along with the replacement of the front. As for this part of the engine, the situation here is slightly different. Everything depends on the need to remove a large number of parts of the car. So, to access the stuffing box, you must first remove the individual suspension components, gearbox and clutch basket from the machine . Next, unscrew all the flywheel bolts and remove it from the crankshaft. Unscrewing the last fixing bolt, you need to remove the locking bar, and then the flywheel itself.

After dismantling the rear clutch plate. We unscrew bolts of a back cover of a crankcase of the engine in quantity of eight pieces and we remove it. We remove the cuff housing from the motor, for convenience you can use a screwdriver, hacking it from the crankcase. Now you can carefully remove the old omental root. It is worth noting that a large number of various covers and parts are made of aluminum alloy, so treat them carefully so as not to add problems in the form of buying a new part.

Mounting the new seal part

Before installing a new seal, wipe the rags in the saddle and lubricate it with oil. Using a mandrel with a diameter of ninety-nine millimeters and a hammer, press the new rear cuff into place. Carry out this stage of work with special care, so as not to damage the element. After the radical packing is pressed, replacing the cuff liner is the next required step of the work. The old gasket is removed (if it has become stuck, you can trim it neatly with a knife), and a new one is installed in its place.

Install the stuffing box housing on the engine

In order not to damage the radial seal during installation, it is necessary to apply a layer of oil to the surface of the crankshaft flange. Mounting the body of the sealant in its place, we correct the lip of the stuffing box with a screwdriver so that it does not have kinks. You can use a kyanku for planting, but do not strongly zealous. Next, you need to start assembling the power unit in the reverse order of the disassembly process. All the work on replacing the glands of the radicals can be considered complete.

Conclusion

As you can see, it is quite possible to repair a car with such characteristic breakage. For this you need only free time, a suitable tool and quality spare parts for VAZ, without which repairs can be considered defective. It is more convenient to work with a partner. But if it is not, you can manage on your own.
