How to disassemble pedals on a speed bike

Platform versions

The configuration of this type of bicycle pedal, which is used on modern models, is a single wide platform. The part is made of reinforced plastic, aluminum or a combined material. The housing is an integral part, in the inner part of which there are bearings, a threaded axle and a washer with a locknut. Additional reflectors may be available.

The advantages of elements of this variety include increased strength, which makes it possible to operate them on mountain, road and urban models. It is not recommended to mount these elements on road modifications due to their large mass. Among other disadvantages are the high price and massiveness.

Design features

Bicycle pedals resemble the front wheel hub in terms of attachment and operation. Naturally, instead of spokes, a platform is fixed on the element to accommodate the user’s leg. A thread is provided on the axle, which serves to fix it on the connecting rod. To understand the features of replacing or repairing a bicycle pedal, you should consider the varieties of the main groups.

It is necessary to distinguish between the left and right pedal, since they have different sides of the thread. Manufacturers make such a difference so that the elements do not unscrew during operation. Parts are marked in a simple way. with the letters R (right) or L (left). Marks are applied to the end part.

Maintenance and lubrication

Bicycle pedal hubs can be lubricated without disassembling completely. To do this, use special oils (“Litol”, TsIFTIM or their analogs). For the cold season, “Litol-24” is best suited, retaining its properties at low temperatures.

  • The bike is placed on its side in such a way that the end of the part to be lubricated looks straight up.
  • Remove the protective cap using a screwdriver or similar tool.
  • Carefully pour oil (about two milliliters), turning the element.
  • The plug is placed in place, the pedal is quickly rotated for several seconds. In this case, the bike is not lifted.
  • Then the bicycle is placed on the wheels, the pedal is turned several times, which should turn easily.

This completes the lubrication process without complete disassembly. It should be noted that this is a temporary measure, since oil will leak out during operation. If possible, it is advisable to change the grease by disassembling the element as described above. The assembly process will be discussed further.

Disassembly

How to disassemble the bicycle pedal after removing it? This operation consists of several stages:

  • Remove the plug on the end of the element. To do this, pry it off with a sharp object, such as a screwdriver.
  • Unscrew the control nut with a spanner wrench, remove the intermediate washer.
  • Carefully unscrew the cone of the bearing block, making sure that the balls do not fall apart. After shooting the part from the axis, it is advisable not to turn the pedal, holding it, in order to avoid the axle falling out of the body.
  • The ball bearings are removed and set aside. Better to count them so that there are no misunderstandings during assembly.
  • Take out the hull axle. The operation is carried out over a table or other surface, since the balls of the second bearing may spill out.
  • Then the elements are taken out and counted. They should coincide in quantity with the first analogue. Do not mix and interchange parts, because during operation they have got used to each other.
  • Cleans attachments of old grease, including cones, seats, axle and everything else. The process is carried out with the help of a clean rag or “wedge”.
  • All elements are inspected for cracks and other damage. In the case of over-tightening the retainers and insufficient oil, the bearing housing can be extremely worn out.

Contact pedals

These products are used as parts for mountain and road bikes. Some craftsmen also mount them on hybrid versions. The system differs from the above-mentioned analogs by the presence of a special mechanism responsible for the reliable fixation of characteristic shoes. The design makes it possible not only to move the pedal along the trajectory, but also to pull it up, which significantly increases the efficiency of driving, reducing the expenditure of physical forces.

The complicated configuration, in turn, leads to an increase in the price of the product, as well as additional costs for the purchase of special shoes. Next, consider methods for replacing, disassembling and lubricating the elements in question.

Assembly

After disassembling and replacing the lubricant, as well as faulty elements, they begin to assemble the part. It is performed in the following sequence:

  • A reasonable amount of grease is applied to the seat of the second bearing. A characteristic indicator is the ability of the balls to stick to it without falling out of the bowl.
  • Place the insides of the second bearing in the bowl. For convenience, tweezers can be used. The balls are pre-counted. It is important not to confuse them with the elements of the first bearing.
  • Position the axle carefully so as not to displace the balls. After placing the part in its place, make sure that it does not fall out back.
  • Apply grease to the seat of the first bearing, put balls on the bowl.
  • A cone is screwed onto the axle, followed by adjustment of the tightening. In the process of tightening the part, check the absence of lateral and longitudinal backlash. They should not be present, but the pedal should rotate easily.
  • Put on a washer, tighten the lock nut, install a protective plug.

This completes the assembly. The right element in the connecting rod is twisted clockwise, the left one. counterclockwise.

How to unscrew the pedals on a bike?

It is very simple to dismantle these elements for repair or replacement. It must be borne in mind that the right and left parts are unscrewed in different directions (the first is clockwise, the second is counterclockwise).

The pedals can be removed using an adjustable wrench or other suitable wrench. Since the gap between the connecting rods is 12 millimeters or less, the length and thickness of the tool edges must be considered.

Partial lubrication

If you are faced with a squeak, but there is no time for serious and thorough repairs, you can use partial lubrication.

It will not eliminate the problem completely, but will only allow you to postpone its solution for a certain time.

Like pain pills, it will relieve pain, and when you have the opportunity, you will undergo a full course of treatment.

Any liquid lubricating oil will work for you. This method does not require unscrewing the pedal from the crank arm. Lay the bike on its side with the end of the pedal facing up. Remove the plug covering the hole where the bushing is located. A knife or screwdriver is suitable for this. Then slowly pour 2-3 ml of oil into the structure. In this case, you need to slowly rotate the pedal so that the lubricating fluid penetrates into the mechanism. Then replace the plug and quickly rotate the pedal again. Finally, lift the machine onto the wheels and rotate the part several times again.

This will help to get rid of unpleasant sensations during driving and difficulties in rotation for a certain period of time. However, pretty soon the oil will leak out, and the above symptoms will manifest themselves. Therefore, for a high-quality “treatment” of bicycle pedals, a complete disassembly of the mechanism will be required.

Reasons for concern

There are a number of signs that indicate that the pedal needs lubrication:

  • Creak;
  • Difficulty rotating;
  • Full pedal stopper.

If you find yourself showing signs of a lack of lubrication, do not postpone the procedure. over, the operation does not require special skills and is quite simple.

Since the hub of the pedals of a bicycle is the same on all types, consider the general procedure that applies to all models.

How to remove the pedals

  • This is best done with the bike on wheels. Why? The fact is that sometimes it takes quite a lot of effort to unscrew it and you have to use the whole body weight. It is easier to do this while the bike is standing on its wheels than when it is hanging from a rack.
  • Remove the right pedal. To do this, it is best to put the right crank at the 3 o’clock position: the crank is horizontal to the ground and turned towards the front wheel. Given that the right pedal has a regular thread, we unscrew it like a regular thread. counterclockwise.
  • Then remove the left pedal. We put the left crank in the 9 o’clock position. It is again horizontal to the ground and angled towards the front wheel. Remember that there is a left-hand thread on the left pedal and unscrew it clockwise.

How to check the pedal

It is advisable to check the condition of the pedals, their tightness, the absence of backlash and the condition of the case before each trip. You can just stand with your foot on it, and then, twisting, watch and listen to how it rotates on the axis. If there is no visual beating and unnecessary sounds. everything is fine, you can go.

Remember, if the pedal twists out, breaks or is lost while driving, you are unlikely to be able to go somewhere, and the risk of injury is quite high.

What tool are pedals removed

  • Open-end wrench 15 mm
  • Various universal bicycle wrenches that have a 15mm wrench.
  • Adjustable wrench.
  • Some models are removable and reattached with 6/8/10 mm hex keys
  • There are special pedal wrenches that combine 15 open-end wrenches and hex wrenches in one tool.

When using an adjustable wrench, be sure to pay attention to its thickness. The fact is that the distance between the pedal mount and the connecting rod is not large, and not every adjustable wrench will fit there. Some types of wrenches come with thin jaws that can be used. Open-end or special pedal keys are great for this operation.

Disassembly of bike pedals

The main feature of disassembling the pedals is that they have different threads.

Therefore, the right pedal is unscrewed counterclockwise, and the left pedal clockwise.

Bicycle Pedal Removal and Installation

To unscrew the pedal from the connecting rod, you need a 15 wrench that can crawl into the gap between these two parts.

After removing the pedal, disconnect the plug and unscrew the lock nut with a socket wrench. Then remove the washer and bearing cone.

The cone should be twisted carefully so as not to lose the balls. Pull out all bearing balls and set them aside.

It is important not to overturn the pedal and support the axle, which can also fall out along with the elements of the second bearing.

It is better to count the balls in order to know the exact number of elements. After that, from the opposite side, you can directly pull out the axis.

Since the balls of the second bearing can be glued to it on old grease, you need to be careful. It is advisable to perform an operation on some kind of rag so that the dropped balls do not roll away.

The balls of the first and second bearing should not be confused, so put them in different places to know the position of each individual element.

Having disassembled the structure, proceed to cleaning. You can remove old grease with ordinary rags and WD-40, which can soften the stuck grease without damaging the parts.

  • the axis is the basis of the entire element, which is a pin made of metal, screwed into the connecting rod;
  • platform. a part directly in contact with the cyclist’s leg, attached to the axle;
  • bearings. elements that provide a movable (do not impede rotation) connection between the axle and the platform;
  • additional parts. bolts, nuts, guaranteeing reliable fixation of all components of the pedal.

Having received information about the structure of this element of the bicycle, you can proceed directly to the repair.

Important! Before proceeding with the repair of the left or right pedal, it is necessary to prepare the corresponding tool. You will need a small adjustable wrench to get to the nut without interference. Puller and pedal wrench: the first is for contact types, the second is for non-standard nuts. Both tools are usually supplied with.

How to disassemble pedals on a bicycle

First, let’s look at the simplest pedal problems (crackling, crunching) that can occur:

  • It is necessary to check for any damage to the pedal (cracks, chips, etc.);
  • Check the place of attachment of the pedal axle to the connecting rods, over time it can weaken or moisture and sand can get into the connection. For prophylaxis, you can unscrew, carefully wipe the axle thread and the connecting rod itself, grease with thick grease and tighten again;
  • We check the pedal for backlash. To do this, we hold the pedal axis and try to move the platform in different directions with our hands. If there is a backlash, then this is corrected by tightening the lock nut, which is located under the plug (see figure)
  • If the pedal is spinning tightly or there is play, it is advisable to completely bust the bicycle pedal. It won’t take you a lot of time.

All you need to remove the pedals from the bicycle crank is an adjustable wrench.

Important. It should be remembered that bicycle pedal threads are different. And if you do not remember in which direction the pedals are unscrewed, we remind you: the axis of the right pedal has a right-hand thread and unscrews counterclockwise, and the left. respectively left and unscrews, as you already understood, clockwise.

  • The pedal axis usually has several edges, which allows you to unscrew it without much effort.
  • Remove the pedal cover with a screwdriver, which is located at the end;
  • Unscrew the lock nut, while holding the axle with a key;
  • Removes the lock washer;
  • Unscrew the cone;
  • We take out the bearings (Be careful, as the balls can roll in different directions)
  • Removes the pedal platform from the axle.

How to lubricate pedals on a bicycle

After the manipulations done, all parts must be thoroughly wiped with a clean cloth. To facilitate the task, you can put all the pedal assemblies in kerosene, then wipe them. This will maximize the cleaning of old grease, sand and other things. Be sure to check the condition of the balls so that they are all the same shape and size.

Then grease all parts with heavy grease, it is recommended to grease with water resistant grease and then reassemble the pedal in the reverse order. Do not forget to wipe the axle thread cleanly and lubricate it with grease before installing the pedal, which will allow you to smoothly put the pedal in place. And next time the pedals will unscrew easily.

How to disassemble a bicycle pedal if you have clipless pedals

Clip-on pedals are more complex and the rotation is tighter. Using an example, let’s look at the maintenance of the most common and cheapest contacts. Shimano PD-M520. If you do not have any problems with the pedals, then it is better not to disassemble them again, so as not to amass unnecessary problems. They do not require frequent maintenance.

They are removed from the connecting rods in the same way as conventional pedals. using a key. To remove the axle, you will need a special tool. a Shimano TL-PD40 crank puller, keys for 7, 10 and 15. For the older Shimano PD-M540 model, such a puller is not required.

  • We put the connecting rod puller on the pedal in the place indicated by the arrow and unscrew it. After that, we easily remove the axle from the pedal body.
  • Holding the axle with a wrench or holding it in a vice, unscrew the lock nut that holds the entire axial structure. Then we take out all the nodes in order, but be careful, as there are balls inside. There should be 12 of them on each side.

The pedal is completely disassembled. Here we do everything the same way, carefully wipe the old grease from all pedal assemblies and grease it with waterproof grease. Putting it up in the reverse order. The balls must be laid out one by one on their seat, having previously lubricated with a thick layer of grease. It is important to tighten the nuts well at the same time so that the pedal rotates smoothly and without backlash. After the manipulations done, remove all excess grease that may be released after tightening the pedal.

The Shimano PD-M520 pedal diagram is shown below for an overview of the component parts.

In the end, I would like to remind you that pedals are subject to great stress and require special attention and respect.

How To Fit & Remove Bike Pedals With Ease

If the thread on the axle “stuck” to the connecting rod and is not removed

  • You can apply WD-40 to the junction for 10-15 minutes and try to unscrew it again.
  • If there is no WD-40, you can use other means (analogs of WD-40) or, for example, kerosene (you need to wait 2-3 hours already).
  • If after that it is difficult to unscrew. try increasing the length of the lever. Just take a longer key or put a metal tube on it to increase the shoulder (Archimedes’ law has not been canceled yet).
  • Some cyclists offer another way. At the junction of the axle and the connecting rod, water is gradually poured from a boiled kettle, forcing the metal to warm up a little and, because of this, reduce the seat density. Personally, I have not tried this option and it seems to me that the boiling water temperature of 90-100 degrees will not heat the connecting rod very much, although it will be washed out for sure.

It is more logical to try to warm up this place with a construction hairdryer or a powerful soldering iron. When working with a hair dryer, heat exactly the junction of the axle and the connecting rod and monitor the temperature of the pedal body, especially if it is plastic.

It’s definitely not worth warming up this place with an open fire.

  • Honestly, you can try to hit the key several times with a hammer in order to at least move the thread off the “dead center”. It is useless to hit the pedal itself, and even more so on the connecting rod. just bend them.
  • Installation instructions

    After analysis, you need to know how to properly install the pedals on the bike. Previously, the joints and parts are cleaned and lubricated. Check the presence of grease on the threads. Additionally treated with anti-corrosion solutions.

    If there are traces of past grease, they are removed with a special degreasing solution.

    Everything is screwed in perpendicular to the axis so as not to skew. Experts recommend that all actions be carried out without tools. You need to tighten it carefully, without damaging the thread. The pedals are installed according to the same algorithm only in the reverse order. Everything is fastened by hand, tightened with keys, excess grease is removed with a rag. After installation, everything is checked in the following sequence:

    • the reliability of the clamps;
    • screed quality;
    • lack of backlash;
    • presence of gaps.

    If necessary, tighten the nuts with a wrench, eliminate the gaps that appear. It is useful to inspect the case for cracks or chips. In a practical test, step on the pedal with your foot and rotate it several times. Check the action visually and by ear.

    An incorrectly installed bicycle pedal is potentially injury-prone. It can jam or fall apart while driving.

    Cycling enthusiasts, professional athletes should investigate the device of transport, individual details. Bicycle maintenance and repair is a simple undertaking if you know the internal components of the structure. It is enough to study the instructions, have a set of keys and materials. By following the algorithm, you can avoid the classic mistakes when changing pedals.

    How to disassemble a bicycle pedal

    If someone thinks that pedals are the most hassle-free and never-breaking parts of a bicycle, he, she or they are wrong. Clip-on pedals can easily fail. Especially when it comes to cheap models. Therefore, you need to choose the pedals with great care.

    Product design

    You need to know how to remove pedals from a bicycle for repair, preventive cleaning. Parts of different types of parts are identical. A distinction is made between standard and clipless pedals. The latter are distinguished by a special fastening for better grip with special shoes. Standard products consist of the following elements:

    How to check the pedal

    It is advisable to check the condition of the pedals, their tightness, the absence of backlash and the condition of the case before each trip. You can just stand with your foot on it, and then, twisting, watch and listen to how it rotates on the axis. If there is no visual beating and unnecessary sounds. everything is fine, you can go.

    Remember, if the pedal twists out, breaks or is lost while driving, you are unlikely to be able to go somewhere, and the risk of injury is quite high.

    How to unscrew the pedals

    Dismantling is carried out in strict sequence. To remove the pedals, free space, materials and tools are prepared in advance. They put the transport on wheels to simplify the process. There is no need to fix the bike. Then remove the right pedal. It is important to know in which direction to set the connecting rod (for the right. at 3 o’clock, for the left. at 9 o’clock).

    The connecting rod should face the front wheel and remain parallel to the floor. The right pedal is turned counterclockwise, and the left pedal clockwise. Remove the pedals for the bike. Cleanse them from dirt and put them aside. The plug is removed from the side of the platform. the lock nut is unscrewed.

    The second key supports the axle when unscrewing the locknut.

    Remove the washer and proceed to the platform last. After the entire system has been removed, remove the bearings. In the process, they use a 15 mm open-end wrench, a 6 x 8 x 10 mm hex wrench, and an adjustable one. The bicycle pedal bushing must be cleaned and lubricated.

    If the bearings are of a modular type, they are removed over a cloth or spread with newspaper so as not to lose the balls.

    Take into account that the thread on the left pedal is in the opposite direction. Before changing the left one, the dismantling of the right part is completed. The rest of the algorithm does not change. For mountain bikes or modified models, remove the products according to the same instructions.

    To remove the right pedal, turn it counterclockwise, with the connecting rod facing the front wheel and staying parallel to the floor
    After completing the dismantling of the right part, proceed to the left. it should be twisted in the opposite direction
    Before installing a new pedal, thoroughly remove dirt from the threaded connections and apply a thin layer of grease
