An experienced worker, to save labor, cleans each piece as it comes off, but the beginner must work more slowly. Have ready a shallow box or tray to receive the parts as they are removed. Lay each part, as it is taken off, in the tray, with the oily side up, for a guide. First, remove the chain, turn it until the nut of the little screw-bolt is found. This little bolt forms one of the link-pins, and can be found quite readily. One end of the bolt has a screw-head notch, and the other a nut and thread. Use the small bicycle screw-wrench for this, a large screw-driver, and a small screw-driver to fit the screw. Turn the chain until the bolt is in a convenient position, then take the large screw-driver or a rod, and place through the spokes of the rear wheel, letting the bar rest on the frame. This will prevent the wheel from turning, and keep the pedals and sprocket-wheel in position; your fingers may be caught and badly cut if this precaution is not taken. Fasten the small wrench on the little nut, and hold it there with one hand, with the other unscrewing the little screw with a small screw-driver. Should the screw fail to yield easily, a drop or two of kerosene will soften the rust and grit, and help to start it.
Return the nut to the screw end, and place it on the tray. Take hold of one end of the chain, and remove the bar that steadies the rear wheel, then turn one of the pedal cranks, and the chain will come off in your hand. The chain should be placed in kerosene and left to soak.
The enamel of the frame should then be carefully rubbed and polished with canton flannel. A clean piece should be kept for the purpose, for if greasy it gives a dull look to the enamel. The plating should be first polished with a cloth, and then if dull with whiting. Nickel plating takes a beautiful polish with electro-silicon used on canton flannel.
Go carefully over each oil-cup, and be sure it is cleaned, and work around the ends of the axles. Ascertain if either wheel needs adjusting, and look carefully to see that the rims are true. A good way to do this is to hold a pencil-top on the frame against the rim of the wheel, and spin the wheel. If it touches evenly all around, the wheel is true; if uneven, take the bicycle to a repair shop and have the wheels trued as soon as possible.
After cleaning all the bearings, put oil in the oil-cups and replace the chain. It is well to leave the chain soaking in kerosene, and later hang it up to drip, and when dry, it will be found bright and clean; or keep a can of lubricating oil in which to soak the chain, and after draining it thoroughly, wipe clean before replacing on the machine. Take an oil-can, and oil each separate rivet. Start the chain on the sprocket, and pull it over the rear sprocket by turning a pedal crank, bringing the ends on the lower side. Place the bar across as before, to keep the sprocket from moving, and then replace the little screw-bolt, using a small wrench, and a screw-driver that fits the screw. Remove the bar, see that the chain is not too tight, and note if it requires any taking up, an adjustment that is done in the rear wheel.
THE BICYCLE TURNED OVER.
Hold the stick of graphite on a convenient surface of the chain, and turn the cranks; then dust the chain to take off any small lumps of the lubricant, and the wheel is ready to be run. Examine the tires and valves, see that the tires are not too soft, and inflate them. See that the valves are in order, then set the wheel right side up. Replace bell and lantern, rub off any finger-marks, and the bicycle is ready.
If the bicycle has been running for some time, and in spite of the care bestowed on it, the chain runs a little heavy, the pedals don’t spin as they should, or the cranks revolve as often as they might, and the wheels are sluggish, there is no remedy but to take down the bicycle, clean it thoroughly, set it up and adjust it. It will require several hours’ hard work to do this, combined with a knowledge of machinery and a knowledge of bicycle working, or else enterprise, care, and common sense.
Begin work on a wheel perfectly free, as far as the outside can be made so, from sand, mud, and grit. Remove the chain and put it to soak. Have a pan of kerosene, and place each small part in that to soak, and any part that has friction surface or is notably oily or greasy.
