The other end will either come to rest on top of the chain or you will be able to insert it in the opening between two rollers. If it drops between the rollers, it means your chain is stretched and should be REI Staff.

Disclaimer: Riding a bicycle can be dangerous, never ride out of your limits and always wear the appropriate amount of protective equipment. When handling certain chemicals for chain maintenance follow all manufactures safety precautions and wear proper protective equipment such as safety glasses, gloves etc.

A bicycle chain is the direct link between the power you put in through your legs and feet to the pedals and to the rear wheel for forward movement. It is important to keep the chain in good condition to optimize shifting performance and maximize its service life. Without proper cleaning and lubricating the chain will collect dirt and debris causing premature wear which can led to degraded shifting performance and eventually breakage, possibly leaving you stranded miles from home or your car.

Intervals of how often the chain should be services depends on your style of riding, riding conditions and usage. Regardless, the following instructions are applicable to all styles of riders and bicycles, including but not limited to road, mountain, BMX, casual etc. Install bike into maintenance stand. Caution should be used when clamping the bike to avoid damage to carbon fiber or suspension style seat posts. The quick link is a visually different link of the chain with a slot. If your chain does not have a quick link proceed to step 3, otherwise proceed to step 4.

Use the chain pliers to squeeze the link together and with a slight twist the chain will come apart. Remove the chain. Using the chain breaker tool select a pin to remove from the chain. If the chain has been repaired using this method before it is recommended that a pin at least four links away be removed. Insert the chain breaker between the links aligning the pin of the tool with the pin of the chain. Ensure the chain is properly seated in the tool prior to actuating the screw. Turn the screw clockwise until the chain pin pushes out of the chain.

You will feel some initial resistance and hear a pop when the chain pin breaks free at the beginning and end of removal, this is normal. Remove the tool from the chain and the chain from the bike.

Place the chain in the container and fill with enough solvent to cover the chain. Put on the lid and shake vigorously for a minute or so. Open the container and discard the used solvent. Replace with fresh solvent and repeat at least once more. It is recommended to repeat this process until the solvents contamination is reduced to only slight discoloration.

You can filter used solvent through a coffee filter and use again for initial chain cleaning in the future. Once satisfied that the chain is sufficiently cleaned, remove from the solvent and wipe dry with a clean rag. You may blow the chain dry with an air nozzle if available or leave to dry for ten minutes. It is also recommended that time be taken here to clean the derailleur, cassette and front chain rings as well as inspect for any damage.

If the chain is damaged or worn replace the chain with new. If installing a new chain begin by degreasing the chain as above and follow the steps below.

Once clean and inspected it is time to reinstall the chain. If installing a new chain, compare the lengths and shorten the new chain if necessary by removing links as described above. Begin by routing the chain over the front sprocket and allowing the chain end to hang. Take the other end of the chain and pass it through the chain stay and seat stay and over the rear cassette.

Route the chain around the back of the cassette and guide the chain around the front side of the upper what level does larvitar evolve in pokemon soul silver jockey wheel and behind the tab on the derailleur guide plate.

Pass the chain around the rear of the lower sprocket idler wheel and pass through derailleur frame. If your bike does not have a rear derailleur simply pass the chain around the front and rear chain rings.

Put one half of the chain quick link into each end of the chain and bring the chain together. Secure the quick link by inserting each of the pins into the corresponding holes and pulling each end of the chain in opposite directions until a click is felt or heard. The chain is properly seated when the quick link pins are at the rear of the slot and no gap is seen.

If your bike does not utilize a quick link proceed to step install a new pin as follows. Begin by removing one additional link from the portion of the chain how to paint lining paper the original pin was removed. If this process has been performed multiple times on the same chain it may be necessary to install a short piece of chain to regain proper length.

Bring the two ends of the chain together and insert the new pin until it stops. Install the chain tool, aligning the pin of the tool with the pin of the chain. Remove the tool and using standard pliers, grasp the pin and break off the protruding portion of the pin. The pin should break easily at the scribed line. To properly lubricate the chain begin by selecting your preferred lubricant.

Manufactures create different what is a jpx file for different conditions, consult your local bike shop to determine what would suit your riding style best.

Rotate the cranks forward and move the chain through the entire range of gears ensuring proper shifting. Once satisfied inspect the chain one last ireland what to see and do for proper quick link or pin installation.

The final product should be a clean chain with no dirt, grease or grime. Only a thin film of oil. This is also a good time to inspect the remainder of the bike.

Remove bike from the maintenance stand and go ride! I used spray lubrication and then started watching youtube videos about chain cleaning, lubrication and waxing. Some time I used rape seed oil but it attract dirt quite a lot. Washing oil off is easier with degreaser or so. Waxing is different, because heat is needed to melt the wax. Oz Cycle made quite a lot of it and I followed. I only wax chain and filter used paraffin. It takes quite a lot of effort, but result is better i think.

Bike manual recommends oil bath for chain. Some quide said heating oil is best for chain bath. Oil atrract dirt more than wax, but is easier to use. I thought of trying paraffin liquid as mid lube between baths. I notice the paraffin contaminates quite a lot because chain is dirty and coffee filter gets stuck with dirt and solid paraffin.

I made it for my neigbours bike chain. It started squeeking aftersnowfall and after driving on wet road, so it is not for wet conditions.

Maybe additives help. I added stearic acid, liquid paraffin and bearing grease. Still it makes dark solution as dirty contaminated lubrication medium. I wonder if it is any difference for all trouble. Maybe production developement. Bearing grease is harmful for skin and environment so have to be careful with that. All other ingredients paraffin wax, liquid paraffin, stearic acid are safe.

Stearic acid is edible, it is fatty acid found in food fat. Paraffin oil is medicine i think for stomach block. Much appreciated! This ible was straightforward and easy to understand, and works well!

May 15,  · With the chain tool (or a hammer) you can push out and push in the pins, allowing you to remove or attach links. Fixing a broken chain amounts to removing the broken link and re-attaching the remaining ends. On bikes with derailleurs there's enough extra links that you can remove a couple without a problem.

This article was co-authored by Ikaika Cox. This article has been viewed , times. If you have a chain breaker tool, also called a chain tool, then fixing a broken bicycle chain is easy. You can do most routine maintenance by yourself, however, you should know that after a chain breaks it's best to get a new chain shortly after making repairs.

With a chain breaker tool, you can easily fix your broken bicycle chain and get riding again right away. You'll just need to remove the broken chain link by pushing its pin out with your chain breaker tool and then connect the 2 ends by pushing a pin between them.

Just avoid using your highest gear until you can add a new link to the chain, since it will be too short for the meantime. Make sure you lubricate your chain with bike grease before you ride it.

Method 1 of Avoid shifting the bike while the chain is broken. Though it may be easier to repair or replace the chain while it's in a lower gear, you should only shift the bike when pedaling. Shifting with a broken chain can cause more problems. Use a chain breaker tool to carefully push the pin halfway out of the broken link. This tool, resembling a medieval torture device, is actually easy to use. Each link of the chain has 2 round pins in it which attach it to the other links.

Find the broken link and note the pin that is keeping it attached to the rest of the chain. Slowly turn your chain breaker tool so the poker pushes the pin out of the link about halfway. Do not push it completely through. Pull the broken link off the pin and discard it.

Remove the broken link while keeping the pin in the chain. This pin will attach to the open link on the other side of the chain to put everything back together. Fit the 2 ends of the chain into one another so the holes line up. The link with the pin in it should be on the outside so that you can push it through all 4 holes 2 on each link to complete your chain.

To get the holes to line up, put the inner plates in the outer plates of the chain. Use your chain breaker tool the other way to push the pin through, completing the link. Before, you screwed the tool in to push the pin out of the link. Now, screw the tool to push the link inward. Work slowly, keeping your hand on the links to ensure it is all lined up. Loosen up the connection to prevent binding.

Grab the chain on each side of your newly connected links and move it from side to side to loosen up the new connection. It can also help to move the chain tool to the other side of the joint just made, and push the pin very slightly to free the 2 outside plates of the link from the central section, preventing binding.

Lubricate your chain with bike grease. Do not use WD, or any other product not made for bike chains. Flip the bike over and pedal it with one hand, dropping bits of lubricant onto the chain with the other. About drops should do. Then, use a damp rag and lightly pat down the chain of any excess oil. When you run a finger on the chain it should come up slick, but not covered in a puddle of lubricant. Avoid using your biggest gear in the back gears, as the chain is now a link too short.

More often than not, the bike won't even let you get into these gears, as the chain is not long enough to reach. However, the strain of trying to hit these bigger cogs will cause another break if you aren't careful. Try to keep your chain straight between the front and back gears. Don't let it stretch diagonally across the gears by being all the way to the right on the front gears and all the way to the left on the back gears at the same time.

This chain fix is generally temporary, and you should add a new link or get a new chain shortly afterward. Method 2 of Add a new link as soon as possible to return your chain to its normal length.

If your chain breaks, you can remove the broken link and reattach the chain for a temporary fix. However, the shorter chain won't be able to fit around all of your gears, severely limiting your range.

You can purchase new links, however, at any bike shop and many sports retailers It's not ideal to use a chain that has links with different levels of wear. The best thing to do is to replace the entire chain instead of adding a new link. Master links are made to fit easily onto a bike. They are easy to install quickly, too, making them handy to keep in your saddle bag on long trips.

They are, by far, the most common links used by home mechanics. Consult a local bike shop to find one that works for your bike. Face the master link the right direction. Most links have an arrow on them that needs to point in the direction the chain goes when pedaling. The rest are concave bending in on one side, and this side needs to face towards the wheel and the rest of the bike.

Pinch the links together to unhook the 2 halves of the master link. You'll notice that the master link has a figure-eight shaped space for the pins, instead of the normal rounded pins and pin-holes for the rest of the chain. If the chain is not already unlocked, do it now. Some master links come as 2 asymmetrical halves: a C-shaped piece with both pins and an outside plate.

To fix these chains, simply thread the C-shaped pin into the both open holes of the broken chain, then fit the plate on top. Take each half and push it through the hole on opposite ends of the chain. Each of the pins on the two halves of the master link needs to go into one of the ends of the chain.

Make sure that the pins go in from opposite sides of the chain as well. You are going to hook the chain back together using the figure-eight hole, and they need to line up. Link the exposed pins through the figure-eight holes on the opposing links. First, bring the chain together. Then, align the holes and push the pins through them.

Note, however, that this connection is currently very loose. Some mechanics use a tensioner, a simple C-shaped wire that hooks into the grooves of the chain, to hold it taut while linking. While not necessary, a set of hands or a similar tool to keep the chain close together makes life much easier. Use a pair of pliers to push the master link together, clicking the pins into place.

You want to force the pins into the other sides of the figure-eight hole to lock them in place. If you don't have a pair of pliers handy, there is one more trick to tighten everything. Flip the bike over so it's upside-down.

Holding the back break down, slowly pedal the bike. As the brake holds the wheel, and thus the chain, in place, the pressure of pedaling will pull the other side, tightening your master link. Know that, in the end, a broken chain usually means you need a brand new one. While you can fix the chain in a variety of ways, as noted, a broken chain usually needs a replacement.

Beyond breaking, old chains expand as the pins inside wear down. This might not sound like much in theory, but it matters when riding. The chain handles and transfers all of the force from your feet to the wheels, and a loose chain means you're doing a lot more work for a lot less speed. The tool is all that is needed when a chain breaks?
