Bicycle is a great form of transport, which is so important for a large number of people. Moreover, it is considered to be a simple device from any point of view. But still, even such a simple device requires frequent maintenance. Thanks to the constant care of the bicycle, you can increase the period of its use, and you will not need to spend money on repairs in service centers.
But, anyway, a certain percentage of cyclists still use the services of a service center, although in most cases you can do everything yourself. For example, to disassemble the carriage on this wonderful transport, no help is needed at all. This is really done without any particular problems.
Necessary tools
For example, to replace the carriage on a bicycle, it is not necessary to even contact a service center. This can be done on your own, without any problems.
To do everything as quickly as possible, you need to immediately prepare a set of tools. To do this, you will definitely need:
- wrench;
- small hammer;
- smooth screwdriver;
- squeeze for connecting rods;
- carriage remover.
What is a bicycle carriage?
The carriage is by its nature the most important part in a bicycle, and it performs a special, one can even say the main role, as it is considered a bearing assembly that connects the connecting rods and the frame. In addition, it provides torque to the connecting rods.
For the carriage in the bicycle system, a special carriage cup is taken into account. It is located in the crossing area of the bicycle feathers, which are located below. Just the individuality of the location of this element affects its fragility. All the blame is dust and debris falling on the carriage. All this spoils her, there is a backlash and unnecessary sounds when driving. You need to directly monitor this. If you do not remove and repair the carriage in time, then it will become difficult to steer the bike over time and even control may be completely lost. Naturally, no one will like to ride with inconvenience. Therefore, it is necessary to eliminate this problem as soon as possible.
Carriage repair
When the carriage is closed, the car does not make any sense to repair it. As a rule, this design is disposable, and in the current situation only carriage replacement will help. But if the carriage is still open, then you can remove it and try to fix it, and then put it back on its previous position.
At the base of the sectional device system is a shaft. Its rotation is guaranteed by bearings that are located inside the carriage cups and are wrapped in a carriage cup. This whole procedure is really very simple, because this type of structure is very simple to unscrew and carry out repairs. How to remove the carriage from the bicycle, we will consider further.
Repair Features
Regarding repairs, the following actions can be applied:
- lubrication of all elements;
- providing ease of rotation;
- elimination of backlash;
- Prevention of third-party sounds while riding.
Carriage Removal: Manual
The design may contain bulk bearings of the bicycle carriage, which may accidentally crumble. Of course, when assembling, they often use non-separable cartridges, but still it is better to check everything at once and make sure.
The most important thing is to always have with you a device called squeezing the connecting rod. This is a very important component, which has two parts. For the main work with the connecting rod, you need the right part, and the left one is for removing the fixing bolt.
Consider how to disassemble a carriage on a bicycle.
Work sequence
- Disassembly begins, as a rule, by unscrewing the tightening bolts that are on the end of the carriage shaft. Next, you will need a pedal key. Many manufacturers decide to cover the screws using plugs. They consist of plastic, so they can be pry off with any tool. This is not a big deal.
- Then you will definitely need squeezing the connecting rods. It will help to tighten the puller all the way from the threaded part to the connecting rod. This should be done as carefully as possible, as you can break the thread and create even more problems.
- A connecting rod is removed from the carriage axis. It is only necessary to wipe the seats well, in order to avoid leaving the old grease and dirt.
- After all, the entire bicycle carriage system is removed. That is why a puller will be needed. It should be noted that you should use only one that is specialized for a particular model of bicycle.
It should be remembered that the removal of the bicycle carriage is only allowed on the left side. The puller must be inserted into the slots on the left, while the wrench must rotate counterclockwise. It is important to keep an eye on this matter, as the puller may become distorted while working with cups on the carriage. If you do all the work quickly and carelessly, this can damage the puller and cup. On the other side, everything is done the same way, only the movements are taken into account - in the clockwise direction.
Thus, the work on removing the bicycle carriage is almost complete. Bearings should be monitored and, of course, it is worth paying attention to the carriage glass. This is a very difficult device to work with. There may be dirt that must be removed.
Useful information about pullers
The puller should only be purchased by type of carriage. If the carriage is equipped with a Shimano model carriage, the puller should also be of the same type. But there are universal models that may work, but not a fact. For example, the ISIS model. It has an eight-slot mount. This device can be used for SRAM, Shimano and Truvativ devices. You can even do without a wrench in case there are special handles on the puller.
When it comes directly to the bicycle carriage, as mentioned earlier, the most important thing is to check whether everything is in order with the bearings. They should be wiped well and garbage removed. To achieve an excellent result, it is recommended to use gasoline or kerosene. After that, grease the seats with high-quality grease. Unfortunately, such mechanisms do not last long, so they need care and a constant inspection.
If there is such a situation that the rear carriage of the bike does not understand, then the quickest solution to the problem is the acquisition of a new mechanism. And you should not even try to do something, as it will be a waste of time and nerves in the void. But as soon as it is decided to go for a new device, it is necessary to find out the shaft length and other characteristics. After all, you can make a mistake in choosing, and spend time again. Therefore, it is better to find out everything, and immediately buy the right thing.
If the bike has an integrated mechanism, then to replace the bearing you need to heed the advice and perfectly follow the rules. First, open the bearings by first removing the boot. You can use a hammer for this procedure, but this is for the most extreme case. Ideally, you need a special puller, as the hammer must be handled very carefully. After that, clean and grease. At the end, put in new industrial bearings.
Installing the carriage in its place
This is not the end of the job, because you need to carefully assemble all this. And the main thing is to do it right, as difficulties can arise. The biggest difficulty is the proper installation of the cups. They have different threads, so you will need high-quality lubrication in order to process the carriage cup, bearings and two threads.
To properly assemble the bicycle carriage, it is recommended to start on the right side and follow the rules:
- The axis of the carriage must be inserted into the right cup.
- Use a puller to tighten.
- Do the same on the left.
- Check bicycle carriage for play. It can be easily understood, as there will be no superfluous sounds and an excellent calm movement will be felt.
- Install the connecting rods and screws to their original positions.
Conclusion
In fact, in theory everything seems much simpler, but in practice it is not so difficult either. After all, even someone who does not have experience in repairing a bicycle can do everything simply by following the instructions. The carriage can really be removed on the first try, and not resort to the help of a service center, while saving some money, even a small one.
It should be concluded that the bike is a very light, useful and interesting form of transport. At the same time, it helps to improve health and most importantly - this is a way to have a great time. Therefore, if every person approaches this issue with all seriousness and always takes care of his bike, he will serve for very long years.
