UAZ "Patriot" pivot: description and replacement

In the front axle of Ulyanovsk carsproduction (in particular, on the "Patriot") there are pivot knots and hinges of equal angular speeds, which provide the transmission of torque to the wheels in any of their positions. In order for the node to work properly, you need to know how to maintain and change the pivot. UAZ "Patriot" (see the photo of the node in the article) is also equipped with them. So, let's look at what this element is for and how to replace it correctly.

Characteristic

What is the pivot? UAZ "Patriot" is equipped with this mechanism from the plant.

The pivot is a rod with a hingedthe combination of a rotary knuckle and a ball bearing. The element is located in the front of the car. The pivot provides the ability to control the wheels without breaking the torque feed.

Functions

This mechanism acts as an axis aroundwhich swings the pivoting fist. Also, the pivot is a connecting component that unites the ball and pivot knuckle into a single unit. The pivot provides the necessary rigidity and perceives the moments of forces from the pivot.

Varieties

There are several types of these mechanisms:

  • Заводской шкворень УАЗ «Патриот».The device design assumes the presence of plastic inserts with a spherical support. The manufacturer produces lightweight components that require adjustment of the gaps. Replacement of pivots on the UAZ "Patriot" with their own hands is made as wear liners. The cost of factory elements is from 5 to 8 thousand rubles per set. The resource is up to 50 thousand kilometers.
  • Reinforced.This is the pivot of UAZ "Patriot" of a new model. It is completed with bronze liners. Often used by amateurs off-road. The mechanism is issued in the form of a repair kit. Who makes this pivot? UAZ "Patriot" can be equipped with elements from the companies "Sollers", "Vaksoil" and "Autohydraulics". The mechanism is marked "for particularly heavy loads". Unlike factory plastic, bronze - more hardy pivot. UAZ "Patriot" with such an element perfectly withstands impact and rotary loads. Reviews say that the element has a resource of 100 thousand kilometers. Thus it is necessary to make lubrication every 20 thousand. Reinforced pivots can be purchased for 8,5 thousand rubles (price per set).
  • Подшипниковый.It is a good analogue factory. The UAZ "Patriot" pivot on bearings does not require constant adjustment and has a long service life. The cost of such a mechanism is 2 thousand rubles per unit.

What to choose?

Выбирая тот или иной тип запчасти, необходимо Remember that each type is suitable for different operating conditions. For example, if you drive mainly in the city, you need to buy a bearing kingpin. UAZ "Patriot", equipped with such a mechanism (with plastic inserts), is controlled very easily. If you often drive in the absence of roads, use items with bronze liners. However, note that the first 2,000 kilometers of the wheel will be very tight. After this period, the mechanism will finally work and will be ready for full operation. Bearing pivots have averaged characteristics on asphalt and dirt roads. Reviews advise to purchase products from the Altai company Vaksoil. She offers king pins with a castor angle of +8. This greatly facilitates driving.

Why fail?

This mechanism fails due todestruction of the rim cups that closes the ball. At some point, this part simply cracks. As soon as the part loses its shape and strength, a backlash appears.

You can determine the malfunction by the characteristic knocking and creaking mechanism in the front of the car. Also, the item fails due to the natural fatigue of the metal.

How to replace? Instruments

To replace the kingpin on the UAZ “Patriot” car, you will need the following tools:

  • A set of heads with a ratchet.
  • A set of open-end wrenches.
  • Lubrication syringe with grease or lithol.
  • A hammer.
  • Puller
  • A set of new pivots.

The important point is that the mechanism changes in pairs, even if the neighboring element is in good condition.

Instructions

So how do you replace this mechanism yourself?Initially, the car is installed on a viewing pit or lift. Next, you need to hang the front wheel with a faulty king pin. Then you need to get to the bipod tie rod. The nuts must be unscrewed using the “24” key. The pivot assembly lubrication bolt is also removed.

На автомобилях УАЗ «Патриот» он расположен in the middle (between the tie rod bolts). Now we need to remove the top pin of the king pin. To extrude it, you need to use a puller. The tool bolt is screwed into the lubrication hole. Further, the puller nut will move down along the thread, thereby pulling the pin of the pivot up. So we extract it from the body of the fist. We extrude the lower part of the element in the same way. Next, remove the ball and carefully clean the knuckle of dirt and dust. Installing a new pivot knot. The important point is that before installing the mechanism must be abundantly treated with grease. This "Litol-24" or grease. Next, the bottom cover is set in place. It is attached to the tie rod bipod bolts. The latter is also fastened in place, and its nuts are tightened, pressing the cap tightly into the body.

Next, install the top cover.She does not sit in the body in full. Therefore, you need to gently knock it with a hammer. Next, the pivot node is “syringe” through a specially designated opening. Then a bolt plug is screwed into it. After installing the bipod tie rod is installed in place of the wheel. The car is removed from the jack. A similar operation is carried out with the neighboring pivot mechanism of the UAZ “Patriot”.

Additional recommendations

When replacing this mechanism, try to avoid tilting the top cover when installing it. To do this, it is better to retract into the case with the help of 4 bolts, and twist them crosswise.

However, even with the correct installation technologythere will still be a small gap near the cover. If water gets here, the node will quickly fail. Therefore, it is important to ensure the tightness of the connection. To do this, you need to install several rubber gaskets. They can be made independently from a bicycle or car camera. During operation, the element will "get used to" and the need for gaskets will disappear - after 500 kilometers we check the gap, remove the rubber elements and fully tighten the bolts. The lid should fit tightly, without gaps.

Why it is impossible to immediately tighten the new part? It's very simple - it can split.

Therefore, wait until the item is fullywill earn, using those linings. Another point - if you install reinforced pins with bronze liners, do not forget to adjust them after a thousand kilometers. Running in should be done sparingly. With proper installation, the element will serve about one hundred thousand kilometers.

Conclusion

So, we figured out what the pins areand how to replace them yourself on the UAZ “Patriot” car. As you can see, the procedure can be done by hand. However, this requires a special puller. Do not forget about the gaps (we seal them with gaskets), which subsequently will be running on.
