How to install the connecting rod. The bike is not so simple

Bicycle maintenance is not such a simple task as it might seem at first glance. Especially if it is carried by a person who has no experience of repair work. Therefore, if your qualification does not allow you to carry out your TOE "iron horse" yourself, it is worth turning to professionals who will be able to implement it correctly. But if you make a final decision to carry out all the work with your own hand or you, for example, the connecting rod on the bicycle is loosened, then it is worth considering the principles of the structure of your "iron friend".

Description

Connecting rods - this is a very important element of the design, which is designed to transmit muscle forces by pulling or pressing the pedal, which through the chain drive system rotates the wheels. And there's nothing worse for a cyclist than unwinding their mounts or even the backlash that occurs while driving. If the connecting rods on the bicycle blur, then in time this malfunction can play a very bad joke with you. After all, this pedal keeps the pedal playing the role of stirrup for the rider, and its loss in the traffic flow can be very dangerous. If, during the movement, the cyclist loses the fulcrum, it affects its concentration and in the future can lead to disastrous consequences - a fall or even an accident.

Basics

The cause of this malfunction is most often the production of the connecting rods or their incorrect mounting with a displacement relative to the axis of the carriage assembly. Although the defect can be formed and through the fault of the manufacturer, but this case is very rare, because in the production process, and the culling of products that do not meet the quality parameters. While the acquired malfunction - due to considerable wear and tear, or low qualification of the installer - is much more common. After all, it is enough to fix the connecting rods on a bicycle with a deviation from the vertical or eccentricity, and the results will be deplorable. When the weight of the cyclist is applied, the splines will be wrinkled, and in the case of the "square" attachment, it will tend to a circle. After all, in the point of application of force very significant loads, and they are able to disrupt the functioning of the entire mechanism. Therefore, the connecting rods on the bicycle must be installed reliably and correctly. Since only in this case their fastening system will evenly distribute the load on the axle, and they will please their owner with a long service life.

Installation

Consider the principles of the correct installation of connecting rods and the main problems that can arise during their running in. If it seems to you that the part is installed correctly and there are no complaints about its quality, then it is necessary to act by an exception method. First you need to make sure that the connecting rods do not have a marriage, and if it is found, then it is necessary to perform a warranty replacement. In the more complicated case, when everything is in order with the part, but it still continues to be untwisted, it is necessary to contact another installer. Despite the fact that many such decision seems too radical, its influence among the amateurs is very underestimated. After all, the connecting rods on the bike are adjusted in space only by the installer, and some malfunctions can be the result of his negligence. Well, the most categorical variant of fastening may be the use of a thread lock. The operation of this glue on metal is expressed in the following: after applying a few drops on the surface of the parts are twisted and form a monolithic connection, which is very difficult to break. The connecting rods on the bike no longer cause any inconvenience, however, their removal is much more complicated. This method is extremely radical and is usually used only in the field or in the hasty elimination of faults, so it should be used with caution and forethought.

Delete

If the maintenance or replacement of connecting rods on a bicycle is assumed, as is usually done during the pre-sale preparation, cleaning or lubrication of the entire system, it is necessary to stock up a special tool. It is very difficult to remove this element from its seat. It boils at the expense of the forces of intermolecular interaction, so the removal of connecting rods is made with considerable effort. To reduce them, special sprays (WD-40 or analogues) can be used, which facilitates slippage of the element along the splines. As a special tool for removing this site, squeeze is used. With one side it turns into a special hole on the connecting rods, and with the opposite side it rotates with a wrench. Efforts that must be applied to the tool must be uniform, as otherwise the connecting rods and their carriage can be damaged. The rod, which is in the center of the squeeze, gradually squeezes the part from its seat, and after a while the process can be considered complete.

conclusions

In the process of work, it is necessary to follow these recommendations, which will simplify their implementation and finally close the question of how to remove the connecting rods on the bike with your own hands. This experience will be very useful for a novice cyclist, as it will allow him to get acquainted with the basics of servicing his transport.
