Install the bike in a comfortable position, in the event that it does not fall. The fact that the removal of the carriage requires some effort, and the precariousness of the structure may strongly interfere.
Put the bike chain on the smallest driving sprocket, and then remove it. The boot has two holes in which to insert the appropriate tool, and then Unscrew the part from the connecting rod. Under the boot you will see a hollow bolt that twisted off the hexagons on 10, and then hold down the pedal.
Remove the washer located under the bolt, and completely remove the inner screw of the puller. Unscrew the puller from the connecting rod and remove the latter from the carriage. Repeat the same operation with the second axis.
Take a special wrench and loosen the lock nut with right-hand thread, which is located on the carriage on the left side. It is necessary to make some effort, but do not overdo it so as not to break the key or damage to the item. In some designs bike the nut is missing.
Insert the slotted groove key for carriage. Remove from the frame with a wrench left Cup adapter which has a right-hand thread. In this case, use tools with long handles to make it easier to rotate and make the effort. Remove the left-hand Cup with bearing.
Go to the right side of the bike on which the sprocket. By a similar method remove the frame from the right Cup, which has left-hand threads. If necessary, make the effort.
Remove the cartridge or the right Cup with the axis of the design of the bike. Thus, the carriage will be lifted. Clean it from Stroy grease with a cloth, then wash all parts in solvent, for example, in kerosene. After they dry out, lubricate the carriage and install back in the bike.
Advice 2: How to remove the carriage off the bike
The carriage of a Bicycle refers to the nodes, the wear as. When this happens, it can be disassembled, replace damaged parts with new, then continue to use the bike.
Take a Bicycle wrench and grab the pedal for a nut located at the place of its connection with the connecting rod. Rotate the nut in the direction opposite to that in which the pedal spins while driving forward. Similarly remove the second pedal.
Remove the nuts that secure the wedges. A hammer to knock them out. Wedges are disposable items after removing them must be replaced. This can be avoided only if they were picked very carefully. Remember, what crankset and pedals are left and which right (on the pedals there are usually special signs in Russian or English).
Now the connecting rods can be removed - open access to the carriage. Its holding nut located on the side opposite to the leading asterisk. For her the loosening use so-called BB key - it is expensive, but allow you to repair the bike more than once. If such key is not present, be sure to get him or, at least, attach to the oblong hole of the nail head and start to spread along the edge is very light strokes so that the nut started to spin counterclockwise. This process will be slow, but in any case, do not try to speed it up, increasing the force of the blows.
Remove the slider and replace it with another. Make sure that the new node was installed with the same side as the old one. Screw the nut first by hand and then, when the power of the hand will miss key or, in extreme cases, as described above, with the only difference that it will have rotated clockwise. Make every effort not to disrupt the thread. Lubricate the new slide. If the chain jumped, put her.
Put the rods and lock them with wedges. Drive a wedge, and when the opposite side would be thread, secure the nuts. Screw in the cranks pedals.
Wear gloves. Beware of getting fingers in the chain and falling of the bike leg. Note that on some bikes the cranks are not attached to the wedges, and in other ways.
Advice 3: How to disassemble the adapter
The adapter is an external power supply for laptop, monitor, or other equipment. This device uses for charging the battery or directly power the device. In some cases, when breakdown becomes necessary to disassemble the adapter.
You will need
- - a towel
- - hammer;
- - the scalpel.
Take a soft towel and wrap it in the adapter. Gently tap with a hammer along the seam to spread the glue. The blows should be sharp enough and strong, but without excessive zeal, not to accidentally damage the case. Experimentally determine the force at which the seam will begin to diverge. Then open the case.
Open the housing using a scalpel, if you are afraid to knock on the adapter with a hammer. However, in this case, you can damage the surface of the body cuts, scrapes and splits, and in the case of excessive zeal may be damaged the Board itself. In the case of towels, and the hammer device will remain unharmed. A scalpel can be applied only in the case that the adapter case is glued tight enough or has a special way of fastening.
Heat a very thin and narrow screwdriver or knife and install it on the seam of the body of the adapter. Press on it until then, until you hear a click. Move the screwdriver along the seam, until you open the case. It must be remembered that in some places there are special clips that need to be open with pressure. If the case is quite badly damaged when disassembling the adapter, it can be assembled using epoxy, which will also replace loose items.
Check the connected wires on the cause of the fault or short. If the failure was in them, then carefully solder the disconnected elements and wrap with electrical tape to prevent shorting. If you have a spare wire that can be cut is faulty and attach a new one. In this case, you must run the wiring connectors.
Assemble the device back and test it. If and now the adapter is not functioning, perhaps the problem is blown PCB components. In this case, you need to buy a new device for recharging equipment.
