HOW TO REPLACE THE BLUE DEVIL HEAD GASKET SEALER ON THE VAZ 2107 DO IT YOURSELF
Blue devil head gasket sealer does not apply to those engine parts that are deteriorating due to wear. If the motor operates in normal mode, it will work without problems until its first or next major overhaul. But in case of serious violations in the operation of the power plant, the blue devil head gasket sealer may fail one of the first.
Blue Devil Head Gasket Sealer
The blue devil head gasket sealer is a single-use part, since its installation changes its physical properties and geometry.
WHAT IS THE BLUE DEVIL HEAD GASKET SEALER
The blue devil head gasket sealer is designed to seal the connection between the cylinder block and the head. Even taking into account the fact that these engine components have ideally flat privalochnye plane, to achieve complete tightness without it will not work, because the pressure in the combustion chambers reaches more than ten atmospheres. In addition, seals require the connection of oil channels and cooling jacket channels. Tightness is achieved by uniformly pressing the gasket during tightening of the connecting elements.
HAT IS MADE BLUE DEVIL HEAD GASKET SEALER
The devil head gasket sealer can be made of different materials:
- metals (copper and aluminum alloys);
- combinations of metal and asbestos;
- combinations of rubber and asbestos;
The main requirements for laying - resistance to high temperatures and the ability to shrink. Each of these materials has its pros and cons. Products made of several layers of metal or asbestos, for example, better withstand high temperatures, but can not provide the best tightness. Parts made of rubber and paronite, on the contrary, maximize the connection between the head and the block, but their temperature stability is lower.
When choosing a devil head gasket sealer, it is better to give preference to a combination product, for example, made of asbestos and metal. Such seals are made of sheet asbestos, but their cylinder bores are reinforced with metal rings. The same rings reinforced the holes for fasteners.
WHAT TO CONSIDER WHEN CHOOSING A BLUE DEVIL HEAD GASKET SEALER
If you are going to replace the devil head gasket sealer, you need to know the exact characteristics of the engine. The fact is that the "sevens" were completed with three types of power plants: VAZ 2103, 2105 and 2106, which have different diameter of cylinders. The first one is 76 mm, the last two - 79 mm. devil head gasket sealer are manufactured according to these dimensions. Therefore, if you purchase a devil head gasket sealer for the engine in 2103 and put it on the power unit 2105 or 2106, the pistons, of course, will tear the edges of the product with all the ensuing consequences. In the case of installation of a devil head gasket sealer with a diameter of the cylinder bore equal to 79 mm on the VAZ 2103 engine, the seal will not provide the necessary tightness due to the fact that the part does not completely block the cylinder bores.
HOW TO FIX AND REPLACE THE VAZ 2107 SEMI-AXIS WITH YOUR OWN HANDS
The rear axle is one of the main transmission units of the car. Not only the driving performance of the car, but also the driver’s safety with passengers depend on the serviceability of its elements. In this article we will talk about the axles of the rear axle of the VAZ 2107, consider the purpose of these parts, the design, possible malfunctions and how to eliminate them on their own.
WHAT IS A HALF-LINE, WHY ARE THEY NEEDED AND HOW ARE THEY ARRANGED?
In the rear-wheel drive cars, which, in fact, refers to the "seven", the rear wheels are leading. They, rotating, force the car to move. Torque to them is transmitted from the gearbox through the drive (cardan) shaft, gearbox and axle shaft. There are only two axes: one for each rear wheel. Their role is to transfer torque from the corresponding gear of the gearbox to the rim.
The half shaft is an all-metal shaft made of steel. At one end there is a flange for mounting the wheel disk, and at the other there are slots for engaging with the gear of the gearbox. If we consider the half shaft assembly, then in addition to the shaft in its design also includes:
Each of the axes is installed in the corresponding (left or right) rear axle housing. An oil deflector with a gasket and a gland serves to prevent lubricant from leaking out of the housing. The bearing is designed to ensure uniform rotation of the axis and the distribution of shock loads from the wheel to the rear axle of the car.
MAIN TECHNICAL CHARACTERISTICS OF SEMI-AXES VAZ 2107 AND THEIR ELEMENTS
Half shafts for the “Seven” in Russia are produced under catalog number 21030–2403069–00. The right and left parts, in contrast to some other rear-wheel drive vehicles, the VAZ 2107 is absolutely identical. They have a diameter of 30 mm (under the bearing) and 22 slots. So-called reinforced semi-axles with 24 slots can be found on sale, but to install them you will need to change the design of the gearbox.
BEARING AXLE SHAFT
The bearing is the element that accounts for most of the loads. And although his claimed resource is about 150 thousand kilometers, he may become unusable much earlier. It all depends on the operating conditions of the vehicle, the health of other parts of the transmission, as well as the quality of its manufacture. The most reliable, to date, are the bearings of the Vologda bearing plant, manufactured under articles 2101–2403080 and 180306. Imported analogues have catalog number 6306 2RS.
