Haro FlightLineTwo RearWheelAssembly Troubleshooting

Troubleshooting for Haro Flightline Two bicycle two.

The tire is the rubber piece that attaches over the rim.

If you notice that the tire looks like it is fine but, when you get on the bike and the tire looks flatter but not completely flat you may need to put air in the tire.

When bike tires sit for a while the tires tend to go flat even if there isn't a hole or anything wrong with it.

The temperature can also effect the tires pressure if it is colder outside. It can be less if the temperature is lower so do not over inflate the tire.

A simple fix to this problem is to inflate the tire back to the specifications of the manufacturer.

The value steam core is the part that keeps the air from coming out of the tire.

If you notice air is not holding into your tire. You can check to see if the valve steam core is loose.

With a valve steam core remover. You can tighten the core(Remember righty-tighty, lefty-loosey).

If the tire does not have a serious issue, and is just flat.

Take a bicycle pump, attach it to the valve stem and pump up tire until it is firm.

If you inflate a flat tire and you can hear air leaking out out then it is possible that the tire has a hole in it.

You can easily find the leak by spraying the tire with soapy water. By doing this bubbles will form from the air escaping from the hole in the tire.

A couple of fixes you can do is at your local Walmart or bike store you can pickup a bottle of the product "Slime". You fill the tire up with slime like you do when you are filling it up with air. The slime will coat the inside of the tire and fill the hole.

Another fix is to get an inner tube for the tire. You fill the tube with air instead of the tire so you by pass the hole.

When riding, does the bike seem unstable?

The locking arm on the wheel is a type of screw, that can be tightened or loosen up

To tighten screw. Turn arm clockwise(righty-tighty). Make sure to lock aim to make sure it closes all the way. If it does not close, loosen up screw.

After desired tightness is achieved place back on bike frame. Readjust if needed.

Does the wheel rim appear to be bent enough to cause it to rub against the bike frame?

Depending on how bent the rim is, there are two options to chose from:

1.Bending rim back into place.
2.Replacing rim all together.

To re-bend back into place. You will need a table vice,and two pieces of thin wood.
(This all depends on how far out the table service can extend out)

Make sure you remove tire and sprocket assemblies

1.Place bare rim in between two pieces of wood in the table vice.
2.Proceed to tighten the vice until rim is bent to a manageable degree.

The pieces of wood act as a split to straighten the rim

Does the chain skip(or jump). When you are peddling?

This mostly due to dirt logged in the bicycle. The following steps will aid you in removing those dirt.

The chain of your bicycle may skip due to dirt lodge between certain parts of the bike. The following steps can be taken in resolving such an issue.

The tools required include:

• Repair stand or way to suspend the bike

• Rags

• Cleaning solvent

• Ruler

• Disposable gloves

• Small screwdriver

• Brush

• Chain-cleaner tool

Rest a ruler at the lower run of the chain and if the distance between the pins of the chain is 12 inches or less. If so the chains are okay. But if it exceed the 12 inch mark by 0.2 inches or more, then the chains are worn out and needs to be replaced.

This step is easier but messy to do. Put on a disposable gloves on and wipe the links in of the chain with a rag damped in a biodegradable solvent (do not use flammable solvents). Remember to clean both sides of the chain thoroughly.

First suspend the bicycle with a repair stand or other bike suspender tools. Attach the Chain-cleaner tool to the lower run of the chain as shown in the picture and start paddling the bicycle to brush the links.

This is done by lifting the chain off the ring and cleaning the large chain-ring with a rag. You can use a screwdriver to knock off any grimy deposits on the surfaces and use a brush to brush it off

Take off the rear wheel of the bicycle and place it on a surface such that the cassette is facing up. Wet the rag with the solvent and slip in between the cogs of the cassette. Move the rag to and fro to clean between the cogs and re-install the wheel.

If there is not dirt logged in your bicycle and the chain still keep skipping, then your Derailleur must be loss. The following steps will aid you in tightening it up.

The front derailleur is the hub of the gear system and when this part falls out of alignment, the entire system suffers. To test it, locate the derailleur at the bottom of the seat tube and ensure that it is parallel and at least 1 to 3 mm above the teeth of the largest chain rings.

If the distance measures too short, use a flat or Phillips screwdriver to give the screw marked L a turn to the right in order to raise the derailleur height. Conversely, if the distance between the components looks too great, adjust the H screw one turn to the right to compensate for the distance difference and ensure the derailleur remains in the proper position for gear alignment.

The three most common reason to adjust the brake pads, are if the brake pads have been worn down; and if the brake cable needs to be adjusted, due to cable stretch.
The tools needed are a full hex key set, Phillips head screwdriver.

If the brake pads have been worn out, then they need to be moved closer together. There are two pads, the inboard and out board pads. The inboard pad, is the pad closet to wheel; while the outboard pad is located farthest from the wheel.
To adjust the inboard pad, place the hex key into the bolt head, located on the outer casing on the inboard pad and turn it clockwise. Turning the inboard pad clockwise, moves the pad closer to the rotor. Move the inboard pad close enough to the rotor, so it is just not touching the rotor. For the outboard pad turn it clockwise and leave a larger distance between the outboard pad and the rotor, then you did for the inboard pad.

If you have excess cable or cable stretch in your braking system and you wish to remove it; loosen the cable anchor bolt. The cable anchor bolt is located, where the cable fastens at the break caliper. To loosen the cable anchor bolt, place one of the keys from key hex set in the bolt groove and turn it counter clockwise. After you have loosened the cable anchor bolt, pull the excess cable through and re-tighten the cable anchor bolt, by turning it clockwise.
