If there’s nowhere to rush

Let’s say you bought new cranks and want to replace them, but the old ones can still last a few days. In this case, you can try the following method:

  • Unscrew the carriage fixing bolts.
  • Spray any penetrating grease into the contact area.
  • Go for a bike ride without screwing in the bolts.

There is a chance that frequent vibrations will cause the connecting rods to come off the shaft by themselves. Be careful, if they fly off at the time of the jump, it will be extremely unpleasant.

The Hollowtech II standard is the least problematic. In order to remove the connecting rods, you only need a 5 mm hexagon, a special wrench for this standard, which can easily be replaced with a 10-11 mm hexagon, and a little effort if the system is stuck to the bearings. Even a child can cope with this.

Carriage difference

How to remove the bottom bracket on a high-speed bike is a separate topic. This is justified by the fact that on such a vehicle, this device has a slightly different form.

On other bicycles where the bottom bracket is of the standard type, it should be externally checked. If it is disassembled, then that is good. But before starting this procedure, you should pay attention to the condition of its bearings. In order to clean the carriage itself and especially its threads, it is necessary to use gasoline. It is important to remember that such devices need regular cleaning, this is necessary for your safe driving.

A little about standards

On bicycles of different classes, it is logical to install bicycle cranks and carriages of different standards. At the moment, the following types of carriage assembly are popular:

  • Standard square mount. the old look for budget bikes.
  • Octalink, invented by Shimano. It has several subspecies, including standards from other manufacturers that are very similar in design. In fact, it is a kind of square carriages, but has a redesigned shaft and modified splines.
  • Hallowtech II is considered the best option in terms of stiffness / weight ratio, but it costs more than others. Also invented by Shimano.

On older bicycles, wedges were a common type of fastening. There were quite a few problems with such a system, which is why it remained in the last century. Now they are practically not produced, and even the most budgetary bicycles are equipped with square-shaft carriages.

How to disassemble and remove the bicycle carriage yourself

Perhaps fans of simple periodic bike rides are not familiar with this term, but those who often use a bicycle as a vehicle, and even more so, professionals in the field of cycling, are aware of what a bottom bracket mechanism is.

Like any mechanism, this part over time is exposed to external influences, wears out or completely becomes unusable, which requires maintenance, full or partial replacement. In any case, you first need to remove the carriage, establish the suitability of the part, and then decide whether to repair it or replace it with a new one.

Carriage Lubrication and Assembly

Using a screwdriver, the walls of the glass are processed. Apply the product in an even thin layer. No need to put grease inside the mountain. This is useless. Then grease is applied to the bearing, which is inserted from the side of the stars. The flat bezel should face outward. Then you need to lubricate the carriage shaft and insert it so that the long end is on the transmission side. In general, the carriage is assembled in the reverse order.

The bearing on the other side is inserted in reverse, with a frame into the glass. The cups are lubricated from the inside, and then put on. It is necessary to tighten until the axial play is completely eliminated. In this case, the rotation of the shaft should be slightly constrained. As soon as the fastening rings are mounted, the cup will move slightly and the axle will rotate freely.

It remains to collect the connecting rods. The most important thing here is to put them on so that when pedaling, God forbid, they do not fall off. Procedure for Effective Connecting Rod Assembly:

  • The square is lubricated with a small amount of grease, this will help to push it deeper onto the axle.
  • Processing a screw with a thread lock.
  • Tighten the connecting rod nut with maximum effort until it stops. You can even lengthen the wrench. the thread will not break.
  • Insert plugs.

A bicycle is an extremely unstable unit, therefore, during any repair work, it must be carefully fixed. The frame will not wiggle back and forth, which eliminates the risk of the bike falling to your feet or hands.

The carriage is assembled and ready for use. In general, the procedure is simple even for the first time, and in the future it will not be difficult to disassemble and install the mechanism at all.

Preventing corrosion

Those who have dealt with stuck spare parts, probably, would not want to repeat this again. To prevent such unpleasant situations, you just need to process the attachment point before installation.

When replacing the connecting rods, apply a little grease to the bottom bracket shaft where it comes into contact with other parts, regardless of type. Do not add too much lubricant, because at the time of pressing, its excess will be squeezed out of the connection and will remain to collect dirt outside of it. Before installation, it is also worth lubricating the threads and even some latches.

Puller Features

Before you know how to remove the carriage from a mountain bike, you need to learn about the puller tool. It must be selected taking into account the appearance and structure of the carriage itself. Often the manufacturer of the carriage must match the manufacturer of the puller. Today, there are universal types of puller in the world, but, unfortunately, they may not be suitable for one or another mechanism. This mechanism is perfect for removing so-called carriage cups. This is precisely the main feature of the mechanism. Therefore, when using such a device, you should be extremely careful and attentive.

When to remove the connecting rod

Usually the connecting rod does not need any special maintenance or service. This part can be replaced in three cases:

  • Since inexpensive bike models are equipped with a non-separable block of a connecting rod together with sprockets, the design is completely replaced. Both new sprockets and two connecting rods are installed as a whole. Considering that a non-separable unit is considered a very inconvenient and impractical option, it is advisable to replace it with a design with a detachable connecting rod and stars.
  • Subject to mechanical damage. The inevitability of removing the connecting rod is due to the need to get to the carriage part, which sometimes requires disassembly, lubrication, washing, adjusting settings.
  • When an unpleasant squeak occurs, which usually appears after rainy weather. As a result, sand gets into the connecting mechanism. Then the connecting rod is disassembled, and the seat is cleaned.

Removing the connecting rods from the bike without a puller

In cases where the cyclist does not have access to a specialized tool, there are comparatively few options left to accomplish the task. To remove cranks from a bike without a puller, you can use the following solutions:

Dismantling technology

Here is a step-by-step photo guide explaining the process visually.

If there’s nowhere to rush

Let’s say you bought new cranks and want to replace them, but the old ones can still last a few days. In this case, you can try the following method:

  • Unscrew the carriage fixing bolts.
  • Spray any penetrating grease into the contact area.
  • Go for a bike ride without screwing in the bolts.

How to remove cranks on a bicycle without a puller

The question of how to remove the connecting rods from a bicycle without a puller arises in situations where it is necessary to dismantle the specified part for replacement and maintenance. To remove the node element in a professional environment, specialized pullers are used. However, if you wish, you can do without it. Let’s figure out how to remove bicycle cranks without using a puller.

Installing the connecting rod

After dismantling the part and performing all the planned manipulations, it is necessary to return the structural element to its original place. Before carrying out work, it is advisable to clean all surfaces and joints, and then process them with a thick lubricant. This approach will allow the connecting rod to be installed evenly and will greatly facilitate the work if it is necessary to dismantle it again.

During installation, the part must be deeply fitted onto the shaft. This will avoid the appearance of backlash during movement. If the connecting rod is not firmly fixed, the socket will gradually become unusable. For reliable fastening of the part, a force of about 50-70 Nm is sufficient.

Tool-free repair is possible

Ordinary users are unlikely to have a connecting rod puller somewhere, especially for the Octalink, although it costs a penny. But sooner or later the moment will come when either the system or the carriage will become unusable and require urgent replacement. If you have the necessary tools, the replacement of these parts is carried out in 10-15 minutes.

The easiest way to remove cranks from a bike without a puller, as mentioned above, is with a hammer. It is relevant for both Octalink and a regular square. The subsequent actions look like this:

  • Remove the plugs from the connecting rods, if present.
  • Using a 13 mm wrench, remove the carriage bolts. Many carriages today have 6mm hex bolts.
  • If you don’t want to visually damage your bike cranks, wrap them in several layers of thick fabric, cardboard, tape, or take a pine block a few centimeters thick. Ideally, a mallet is suitable for such an unusual task.
  • Flip the bike over against the handlebars and saddle.
  • Begin tapping the connecting rod with moderate force from the inside, as close to the axle as possible. You can hit the connecting rod from time to time from the outside in order to somehow stir it up.
  • If the structure is pressed very tightly, you can try to hit pointwise with a chisel or a beard attached to the connecting rod head.

Please note: Using this method, you can damage the frame, the bottom bracket assembly, or the connecting rod itself. In addition, any impact on the stars is likely to deform them and render them unusable.

It is worth saying that removing stuck connecting rods can be problematic, even with a puller. Most likely, in this way you will not be able to remove the stuck bicycle crank, no matter how hard you try. But do not despair, for such cases they came up with other ways.

When is it necessary to dismantle the connecting rod

The connecting rod does not imply any maintenance and special care. Its replacement is carried out only in the case that we described above and in case of mechanical damage. The need for dismantling arises when we need to get to the carriage or completely disassemble it for lubrication, flushing or adjustments.

Also, sometimes after the rain, an unpleasant creak occurs, which is caused by the ingress of sand into the connecting rod-shaft interface. In this case, you have to disassemble it and clean the seat.

It’s just that the connecting rod will not be removed and for this you need to apply either a certain manual dexterity or a special puller. We will tell you about these methods in detail.

Removing the connecting rods from the bike without a puller

In cases where the cyclist does not have access to a specialized tool, there are comparatively few options left to accomplish the task. To remove cranks from a bike without a puller, you can use the following solutions:

  • Try to forcefully dismantle the connecting rod. Of course, in the case of using a sledgehammer, there is a high probability of causing irreparable damage to the bearings and carriage. Although the idea may pay off, it may be because of your own laziness that you will have to resort to additional costs for repairing other parts.
  • The second option involves abundant treatment of the joints with lubricants, followed by unscrewing the bolts. With the fasteners released, it is enough to ride a bicycle a few hundred meters, applying maximum pressure on the cranks.

Removal technology description

There are several options for removing the connecting rods. Most often, users work with a puller. it’s easier and faster. If it was not available, you should read the instructions for dismantling without this tool.

What are connecting rods?

The connecting rod is a part that carries one of the most significant loads during movement. There are blocks of chainrings that are motionlessly connected to the connecting rod. In this case, if a breakdown occurs, it is necessary to replace both connecting rods. On bikes in the upper price bracket, the stars can be changed by disconnecting from the connecting rod as they wear out.

Questions about how to remove the cranks from a bike without a puller begin to bother bike owners if these parts are damaged. It is necessary to dismantle the element in order to gain free access to the carriage when adjusting it.

In what situations it may be necessary to dismantle the connecting rod?

The connecting rod is a fairly simple part that does not need much maintenance and care. Component replacement is most often done due to mechanical damage. The need for removal may also arise when it is necessary to gain free access to the carriage, perform adjustments or flush the system.

Often, after driving in rainy weather, unpleasant squeaks occur in the carriage area, the cause of which is the ingress of sand and dirt into the nodal mechanism. In this case, it may be necessary to remove the connecting rod to clean the seat.

Types of connecting rods

  • One-piece. presented in the form of a monolithic structure, where the left and right elements are fixedly mounted on the axis. The advantage of this solution is high reliability, ease of maintenance and low weight due to the lack of fasteners.
  • Two-piece. the axle, the right connecting rod and the drive sprocket are combined into a single structure. Left crank arm attaches to the system by means of a nut fit.
  • Three-part is the most common option. Presented as a separate axle, as well as right and left connecting rods connected to a sprocket.

Device and purpose of the part

A bicycle connecting rod is a metal lever that has a large and a small head on the rod. This element is of several types:

  • One-component. They represent a single structure. left, right connecting rod, axle. The advantages of this type are great strength, easy maintenance, but they have a significant weight;
  • Two-component. Here, the drive sprocket, the right connecting rod and the axle are connected, and the left one is connected separately with a nut;
  • Three-part. This most famous and popular system is the axle, the left connecting rod and the right one together with the sprocket.

The load on the connecting rod is very high, and therefore they are most often made from solid steel, but there are also options from aluminum alloys, for example, in sports type bicycles or imported models. Inexpensive two-wheeled vehicles have a front sprocket block, combined with a connecting rod and non-separable. In this case, when replacing the sprockets, both connecting rods must be replaced. New ones are selected depending on the type of existing carriage.

This part of the bicycle can also have various types of fastening, for example, a square, a slot. The first is used in professional sports models of equipment, and there is also the latest development. a rotary system.

Types of fasteners

To understand how to remove the cranks from a bicycle without a puller, it is important to understand the types of mounts that are used to connect the part to the sprockets. Modern products can be installed using nuts, splines or fasteners made in the form of specific squares. Rotary joining is also available today.
