How to remove asterisks from the rear wheel of a bicycle: step-by-step instruction

With active skating, the bicycle graduallywear out. To avoid this, we must constantly look after him. One of the most vulnerable places in high-speed bikes is the rear of the transmission. So sometimes it needs a replacement. How do I remove the asterisks from the rear wheel of a bicycle?

Why is this necessary?

The most common problem is wear and tearchain. If it is not replaced in time, then it will start to bore the stars. Each has its own favorite transmission, which is most often used. Over time, the chain on it will start to scroll, if you put a heavy load. Therefore, you must learn to remove the asterisks from the rear wheel of the bicycle. Once this skill is acquired, you can eliminate any damage yourself. And this saves a lot of money on maintenance in the workshop.

What for it is necessary? It is possible to remove the asterisks from the rear wheel of the bicycle for both normal lubrication and for their complete replacement. They will also interfere if you need to replace the knitting needles on the right side or get to the hub itself.

The difference between ratchet and cassette

Before you remove the asterisks from the rear wheel of the bicycle, you need to decide on their design. It is important to distinguish between a ratchet and a cassette. They outwardly though and are similar, but inside strongly differ.

In the ratchet, the freewheel mechanism is installedtogether with asterisks. It is such a monolithic system, which is simply bolted to the bushing. The cassette can be disassembled, therefore it is possible to replace one worn out star. Unlike the ratchet, it is not a monolith with the free-wheel mechanism, but is worn on it.

To remove them, you need different pullers. It is important not to confuse them with each other, because they are not interchangeable. They have different slots. If you are still afraid of not distinguishing the rattle from the cassette, a great help in this matter will be a photo.

How do I remove asterisks from the rear wheel of a bicycle?

If it's a rattle, then everything will be a little easier. If there is special equipment, then even a person who has nothing to do with bicycles can cope with this.

For this, only 2 tools are needed:

• special puller;
• adjustable wrench.

To begin with, of course, you need to remove the wheel. Then the asterisks are removed by two actions. It is necessary to insert the puller into the ratchet, and then with the key, try turning it counter-clockwise.

If the mechanism has never been removed, it canstrongly twist (this is his property) and not succumb to even under great effort. Then you need to splash from the side of the thread there Wonder WD-40 spray. If you leave it that way for several hours, then the rattle can easily be removed. Also it must be remembered that the more the lever, the greater the effort. Therefore, you need to take the biggest wrench. Make a couple of jerks, and the ratchet will easily unscrew.

To remove a cassette, you will need one moretool. It's called a whip. It's such a handle, to which a piece of a bicycle chain is attached. If the cassette is turned counter-clockwise, it will start to rotate. Here, and this whip is useful, which will keep it. Some craftsmen simply use a piece of the old chain instead of this tool. Next comes the same thing as when removing the ratchet.

How do I remove asterisks from the rear wheel of a bicycle without a puller?

For such an operation, you can not buy a special tool. The truth with him is much easier to manage. In order to remove the ratchet without a stripper, you will need:

• gas key;
• core;
• a hammer.

The ratchet has 2 notches. There you need to insert the punch and hit it with a hammer. It must be clockwise. Instead, you can use a large nail. You need to be careful, since under this place are the bearings. With a little effort, you can screw the asterisks.

There is still the inner part of the rattle. It is removed with a gas wrench, which is turned counter-clockwise.
