In detail: do-it-yourself balancer repair from a real master for the site my.housecope.com.
Yesterday I decided to look at the balances .. several tailless ones had already accumulated and it was necessary to return them to the ranks.
A material like polycarbonate, which is what greenhouses are fashionable now.
1. Cut the squares from the material
2. Then bend the square in half.
3. We give it the shape of the future tail.
4. Make an incision in the front of the tail as long as the tail will sit exactly on the balance body.
5. Then, with small side cutters, we already make a notch for the balance body.
well and then glue the tail into the body of the balance with a second glue, I usually use a monolith. But usually I put several layers.
Well, here the tails are already on the balances.
I use such a repair due to the fact that it's easier to do it))), of course, you can get confused with some other glue, but it's kind of simple ... quickly cut, glued, several layers and it's almost done)) As if it's done, but balances will have to be looked at in the water)) And it is possible to bend the tail or cut it)) In short, adjust.
Perhaps someone doubts the strength of the glue ... but here is a photo of the balance that I caught on the last fishing trip
It shows traces of pike teeth ... marks from the inside.
There is also one more report on fishing on the balance after repair)))
And I do not cut out a piece, but bend it inward and then put it on a hook. A little more fiddling, but even if the glue is chipped, the tail will not be lost
Thank you for your comment and good advice. Yes, indeed, if you fasten it on a hook, it will be stronger, and it will probably also be possible to restore the tail right on the fishing trip, if you need to return the balance to the system on this particular fishing trip))) I somehow did not think about it at all)))

Often, winter fishing anglers are faced with such a problem when a catchy, and therefore a favorite bait - a balancer, unexpectedly fails. The most fragile place of this bait is the plastic stabilizer tail; its failure is the most frequent breakdown of this bait.
You can repair the balancer right next to the hole
Going on vacation to Russian resorts, near the city Sochi, we advise you to book a room in the all-season hotel Gala Plaza Krasnaya Polyana. This hotel is located in the most picturesque corner at the very foot of the Aibga mountains, Achishkho, nearby the mountain river Mzymta carries its waters, which flows from the foothills of the Caucasus and flows into the Black Sea. There is unmatched fishing and recreation at any time of the year.The hotel has a developed infrastructure and the highest level of service.
Balancer stabilizer can easily fall off at the most unexpected moment, which often happens with cheap fakes. If this trouble happened not in the hole, then repairing the balancer will not be difficult - you can glue the tail in place using good quality waterproof glue.
But often, the balance beam loses its tail directly in the water, not withstanding the pressure of the predator's jaws. What to do in a situation like this and how to repair balancer? It is a pity to throw away the broken bait, especially if it is a branded expensive balancer. Of course, you can try fishing on a balancer without a tail, but the bait will change its game, so it will not be as catchy as before. The Hunting and Fishing website offers readers an interesting and not too complicated balancer repair method.
To repair the balancer you need:
- a piece of heat-shrinkable tube, which, when heated with hot air or over an open fire up to 130 ° -200 ° C, will shrink up to three times in diameter;
- open fire (a simple lighter will do);
- file.
Before you start repairing a broken rocker, you should remove all remnants of the stabilizer from plastic and any paint or glue smudges in the tail area. Then, on the body of the balancer, 5-7 mm from the end from the tail, we saw through a thin annular groove. This is optional, but highly recommendatory if time permits.
Then you need to pick up and attach the tube. When choosing a heat-shrinkable tube in order to repair the balancer, one must not forget that during heating, the tube will decrease not only in diameter, but also become shorter, and the thickness of the walls will increase. For example, to repair the tail of a balancer, which is 5 cm long, a tube with an 8 mm diameter and a length of about 35-40 mm will fit (Fig. 1-1). The tube should not only fit snugly on the balancer, but also provide the required tail width.
Having found a tube with the required parameters, you need to put the bait's tail hook inside and push the balancer body by 7-8 mm. (Fig. 1-2), and then pierce the wall of the tube with a hook, bringing it out (Fig. 1-3).
The next step - the most important - is the shrinkage of the tube.
One must manage not to set fire to the pipe over the flame from the lighter. First, we heat the part of the tube that is worn on the bait. To do this, hold the balancer by the front hook and rotate it over the flame around its axis, then the shrinkage will be uniform (Fig. 2-4). Then, after the tube has tightly wrapped around the body of the balancer, it is necessary to heat the part of the tube that is put on the shank of the hook in order to also settle it a little (Fig. 2-5). Now it remains to form the tail of the balancer.
This can be done in one of two ways:
We slightly heat the remaining part of the tube, not seated on the balancer, and flatten it in the horizontal plane with our fingers, forming it slightly concave at the bottom. After the tube has cooled down, you need to cut off all excess with scissors, giving the required shape to the stabilizer (Fig. 2-6, 7).
to get the tail of the required shape and size, you can, following the sediment of the tube on the forend of the hook, insert a small wedge inside the tube, which is cut out of a plastic bottle or tin can made of aluminum (Fig. 3-8). When the tail of the balancer with aluminum insert has cooled, it can be bent as required.
Balancer repair using a heat-shrinkable tube will do without any costs and fixtures. It can be carried out directly near the hole. The refurbished balancer is in no way inferior to branded lures with a whole stabilizer tail.
The most common "sore" is the wear of the balancer bushings! The second problem is the wear of the cheeks under the spring. The permissible clearance between the axle and the balancer bushings according to the manufacturer's passport is 1 mm.In fact, with such a gap, the bushing is subjected to enormous loads, especially when turning.
There are 4 types of bushings made of different materials: bronze bushings, aluminum with zinc, just aluminum and plastic! We use alloy bushings: aluminum with zinc, bronze, I'll tell you why! If the axle of the balancer is in normal condition, that is, its cylindrical wear is 0.1 - 0.2 mm, then you can safely use bushings with zinc, they are strong enough and one and a half times cheaper than bronze ones, but they are quite fragile, on worn axles they break off " collar ”. If the axle is worn more than 0.2 mm, it is advisable to use bronze bushings, since bronze is more viscous than zinc and holds heavy loads, especially, I will repeat it again when turning! We do not use aluminum and plastic bushings for the reason that, with today's overloads of machines, they simply do not withstand the loads and after 2 years of operation they simply interrupt, at least on grain carriers.
We practice working on the axle on the spot, without removing the axle itself from the machine. Take a loop of a machine, a liqueur ruler or just a square, a micrometer and having a certain skill and practice, the axis is aligned in cylindricality within up to 87.5 mm. Thus, the life of this axis is extended. In another case, the axle is removed from the machine, installed on a cylindrical grinder and the necks are ground under the bushings, the recommended size, depending on wear, is minimum up to 86 mm. Then the repair bushings are pressed into the shoe and bored to the axle size, the bushings are ordered specifically for repair. In this case, the cementation is completely gone, the axis becomes “wet”, but the cylindricality is restored. It is recommended to install such axles on dump trucks where the axle load is less than on grain trucks!
The third method is surfacing, grooving and axle grinding. We made a dozen of such axes and abandoned this method. Every second axle broke, during surfacing, the structure of the metal changes and the axle, not withstanding the previous loads, breaks.
This is, in short, everything I wanted to tell you about replacing the balancer bushings. Goodbye everyone, watch our blog on Youtube

I experimented with replacing hooks with one balancer, even, it seems, the same company:. 8 & start = 15
Soldered. You can see what happened. But it was possible to remove the coating from them neatly, and then glue it in place.

Balance bar bush wear is the most common "ailment". The second problem is the wear of the cheeks under the spring. A gap is allowed between the bushings and the axis of the balancer (according to the manufacturer's passport - about 1 millimeter). With this clearance, in fact, heavy loads are applied to the hub, especially when turning.
There are four types of bushings in different materials: aluminum with zinc, bronze bushings, ordinary plastic and aluminum. In our company, bushings made of bronze and an aluminum-zinc alloy are more often used.
The point is that the balance bar axis is in a normal state, i.e. in terms of cylindricality, its wear is 0.1-0.2 millimeters, in this case bushings with zinc, which are quite strong and one and a half times cheaper than bronze ones, are ideal, but they are rather fragile (a "collar" breaks off on them on worn axles).
When the axle is worn out by more than 0.2 millimeters, it is recommended to use bronze bushings during the overhaul of KAMAZ, because bronze is more viscous than zinc and is able to withstand heavy loads, especially when cornering.Plastic and aluminum bushings are not used, because the parts do not withstand loads and after two years of operation interrupts them.
You should talk about bushing boring and clearances. First of all, it is necessary to correctly select the bushings in size, or rather, in terms of the inner and outer diameters.
For tight fitting of the bushing into the balancer, it must have an outer diameter of 100.2-100.3 millimeters; on bronze bushings, a size of up to 100.5 millimeters is allowed. The bushing must have an inner diameter of 0.5-1 mm less than the nominal value for high-quality boring of the balance bar with bushings.
Boring the bushings on a lathe and further pressing will not give the desired result, because the balancer quite often has a tapered and ellipsoidal seat, the outer diameter of the bushing also has an allowance of 0.2-0.3 millimeters, therefore, after pressing the bushings with 2- x sides, the alignment between them will not be ideal, the inner size of the bushing will repeat all the errors of the balance bar, and as a result, it will be almost impossible to fit along the diameter of the axis. That is why the bushings are pressed into the balancer, installed on the boring machine, then two bushings are calculated simultaneously from the 1st installation.
The bushings must have a calculated diameter 0.05-0.08 millimeters larger than the balance bar axis. If the standard axle has a diameter of 88, then the seat in the balance bar will have a size of 88.05-88.08. The smaller the clearance between the bushings and the axle, the longer it will take for it to wear to critical dimensions.
With every tenth millimeter of the bushing wear, the wear rate increases dramatically, because due to the clearance, the balance bar can swing in different planes, wearing out the axle and bushings. Therefore, the practice of our company allows us to say that before replacing the balancer bushings, the maximum clearance should be no more than 0.5 mm.
You should also touch on the topic of wear on the balance beam axis. The technological procedure for the manufacture of the axles of the balancer is rather complicated and can be carried out only in the factory. The difficulty lies in the fact that this is not just turning grinding, processing the ends for shoes and pressing into brackets, but also heat treatment of areas for bushings.
The ideal situation was in Soviet times, when the places for the bushings were hardened, cemented and ground. The bushing spaces have a Rockwell hardness of 62-64 HRc, which is equal to the hardness of a file. The balancer bush is a softer material and is a replaceable element. Due to the fact that in the old shoes the bushings were lubricated with a “hoist”, which was poured inside, good sliding was ensured, the hardness of the axles did not allow the bushing material to rivet on it.
With the timely replacement of the shoe sleeve and the non-lubrication of the oil, the axle could serve up to 30 years, with less wear (up to 0.2 millimeters). In modern conditions, without a loss of production culture and without quality control, the reliability of spare parts cannot withstand criticism, so it is not surprising that the axles of the balancer are not thermally processed on new trucks, on which axle wear in 2 years is up to 1 millimeter.
In such shoes, lubrication is provided only through grease fittings, there are no oil seals. Therefore, when moisture gets into the shoe and is not pumped out in time, rust and dirt accumulate in the bushings, which affects the axle wear, like emery. In addition, during our reloading of vehicles, especially grain carriers loaded as railway wagons, the plastic bushings break the axle, reaching the body of the shoe.
Basically, the axis of the balancer is produced in a barrel-shaped manner and from below, however, the part of it, where there is no contact with the bushings, does not wear out (this is a gap of 20 millimeters, where the bushings have a distance between themselves in the shoe). Therefore, even when the axle is worn, the size of the shoe bushings during replacement must be standard, otherwise they will not be able to sit in their place.
In our company, it is practiced to work on the axle on the spot without removing it from the car. When performing overhaul of a KAMAZ internal combustion engine, a grinder, a square, a curved ruler or a micrometer are used and the axis is aligned within 87.5 millimeters in cylindricality. This extends the life of the axis.
Another option involves removing the axle from the car, installing it on a cylindrical grinding machine, grinding the neck to fit the bushings. The recommended size, depending on wear, is up to 86 millimeters. Repair bushings are pressed into the shoe and bored along the axis size, bushings for repair are ordered.
In this case, the cementing leaves, the axis becomes "wet", however, it is restored to cylindricality. Such axles are recommended for installation on dump trucks, where axle loads are less than those of grain carriers.
The third method involves grooving, surfacing and grinding the axle. The craftsmen of our company made a large number of such axes and turned out to be from this method. Many axles break, during surfacing the structure of the metal changes and the axle does not withstand loads.
Very often, winter fishermen have to face such a problem when their favorite and catchy bait, the balancer, suddenly fails. The most fragile part of the balancers is the plastic stabilizer tail. And it is the failure of such a tail that is the most frequent breakdown of the balancer.
The balancer stabilizer can simply fall off at the most inopportune moment, which is often the case with cheap fakes. And if this did not happen in the hole, then repairing the balancer will not be difficult. To do this, you can simply glue it in place with good waterproof glue and the bait is restored.
But quite often it happens that the balancer loses its tail right in the water, unable to withstand the pressure of the pike's jaws. In this situation, the question becomes.
What to do and how to repair the balancer? It is a pity to throw away the damaged balancer, especially if it is an expensive branded balancer. You can, of course, try to fish on a tailless balancer, there are even some models that are already produced without a tail. But at the same time, the balancer will lose its game and become less catchy. A very interesting and rather simple way to repair the balancer was suggested by the Muscovite A. Guskov in the fishing newspaper Rybak Rybaka No. 9 2008.
Balancer repair and restoration.
To repair the balancer you will need: a piece of a heat-shrinkable tube, which, when heated with hot air or an open flame to 120 ° -180 ° C, shrinks up to three times in diameter; file; open fire (regular lighter).
When starting to repair the balancer, it is necessary to remove from the balancer the remains of the plastic stabilizer and the accumulation of glue and paint in the tail section. Then, on the body of the balancer 5-7 mm. from the tail end, saw through a shallow annular groove. This operation is not necessary, but if you have time, it is better to do it.
The next stage of the balancer repair is the selection and fitting of the tube.
When choosing a heat-shrinkable tube for repairing the balancer, it should be remembered that when heated, the tube decreases not only in diameter, but also shortens in length and increases the thickness of the walls. For example, an 8mm tube will work to repair the tail of a 5cm balancer. and 35-40 mm long (see photo 1)... The diameter of the tube should provide, in addition to a tight fit on the body of the balancer, also a sufficient width of the tail.
Having picked up the necessary tube, it is necessary to put the tail hook of the balance bar into it and push it onto the bait body by 7-8 mm. (photo 2) and pierce the wall of the tube with a hook and bring it out (photo 3).
Next comes the most crucial stage of balancer repair - tube shrinkage.
The main thing here is not to set fire to the pipe on the flame of the lighter. First, the part of the tube that is put on the bait is heated. To do this, hold the balancer by the front hook, turn it over the flame around the axis so that the shrinkage is uniform. (photo 4)... After the tube has tightly wrapped around the body of the bait, we heat part of the tube on the forend of the hook in order to also slightly restrain it (photo 5)... Next, we proceed to the formation of the tail of the balancer itself.
There are two options for tail shaping:
• You can slightly heat the remaining, not shrunk, part of the tube and flatten it with your fingers in a horizontal plane, making it slightly concave from below. After cooling, trim off the excess with scissors and give the necessary shape to the stabilizer (photo 6, 7);
• to get the tail of the required size and shape, after settling the tube on the forend of the hook, insert a wedge cut from a plastic bottle or aluminum can into the tube (photo 8). After cooling, the tail of the balancer with an aluminum insert can be bent as you like.
Repair of balancers using a heat-shrinkable tube does not require special tools and costs. You can make such a repair without leaving the hole. At the same time, the balancer repaired in this way is in no way inferior in efficiency to balancer arms with a proprietary stabilizer tail.
In modern Kama 3-axle trucks, 2-axle and 3-axle semi-trailers, a suspension is used, at the ends of which there are springs resting on the rear axles, between them on the frame there is a balancing mechanism.
The purpose of the KamAZ balancer:
- compensation of vertical loads;
- stabilization of lateral displacement;
- reduced wear of the undercarriage;
- maintaining stability.
The balancer device contains, depending on the machine design, 1 or 2 transverse axes:
- In the 1-axle mechanism, the spring connection is reinforced with ladders.
- With 2 axles, it is pressed into brackets connected with a tie, fixed with studs to the rear suspension elements. The latter are connected to the welded frame side members with reinforced bolts.
At each free end of the axle there are spring shoes. They fix the parts, have a plug hole through which oil liquid is poured, and are equipped with seals:
- rubber cuffs prevent oil leakage;
- rings protect the interior from dirt.
A special bushing made of a material with a low coefficient of friction and increased resistance to wear is installed at the point of attachment of the shoe. The manufacturer most often makes it from aluminum or bronze.
Modern trucks are equipped with aluminum-zinc alloy or PTFE bushings.
The lubrication in the shoes is liquid or consistent. When installing polymer sleeves, a dense fill is used, which requires less maintenance.
During the operation of KamAZ, the balancer, despite the strength of the parts, wears out, which leads to the breakdown of its units. Therefore, inspection and maintenance are performed in a timely manner in specialized service centers or by hand.
