Depends on what's wrong with it. Sprockets usually don't break in any other way than wearing out, and usually require special tools to be removed. Take it to a bike shop.
you would first take a marker and put the sprocket on the ground and where it is bent mark it then put the sprocket on a flat space and heat the part where it is bent take a hammer and hit it soft it should fix it right up
Fig. 11 Valve Timing MarksRemove engine front cover as outlined previously.Remove crankshaft oil slinger.Crank engine until timing marks on sprockets are in alignment, Fig. 11.Remove three camshaft to sprocket bolts.Remove camshaft sprocket and timing chain together. Sprocket is a light press fit on camshaft for approximately 1/8 inch. If sprocket does not come off easily, a light blow with a plastic hammer on the lower edge of the sprocket should dislodge it.If crankshaft sprocket is to be replaced, remove it with a suitable gear puller. Install new sprocket, aligning key and keyway.Install chain on camshaft sprocket. Hold sprocket vertical with chain hanging below and shift around to align the timing marks on sprockets.Align dowel in camshaft with dowel hole in sprocket and install sprocket on camshaft. Do not attempt to drive sprocket on camshaft as welch plug at rear of engine can be dislodged.Draw sprocket onto camshaft, using the three mounting bolts. Tighten to specifications.Lubricate timing chain with engine oil and install cover.
a large sprocket
It depends on whether you are talking about the front sprocket (the one at the pedals, called a chainring) or the sprocket at the rear derailleur. The lowest gear at the front is the smallest sprocket/chainring. The lowest gear at the rear is the largest sprocket. So if you combine the smallest sprocket at the front with the largest sprocket in the rear you have the lowest gear available on your bike.
To replace a bike sprocket, you will need to first remove the chain from the sprocket. Then, use a wrench to loosen the bolts holding the sprocket in place. Once the bolts are removed, take off the old sprocket and replace it with the new one. Secure the new sprocket in place by tightening the bolts. Finally, reattach the chain to the new sprocket.
Sprocket and chain and what?
depends if the sprocket is bigger or smaller than a stock sprocket.
To remove a sprocket using a sprocket removal tool, first, place the tool over the sprocket and ensure it is securely in place. Then, use a wrench to turn the tool in a counterclockwise direction to loosen and remove the sprocket. Be sure to follow the manufacturer's instructions for the specific tool you are using to avoid damaging the sprocket or tool.
first. take the left side rear wheel off. then remove the 4 bolts that hold the sprocket to the sprocket holder. then remove sprocket
A sprocket is a lever.
The sprocket on the nose of the crankshaft that drives the cam sprocket.
A minimum plain bore sprocket is a roller chain sprocket with a hole drilled through the center. A finished bore sprocket is a roller chain sprocket with a hole drilled through the center augmented by either a keyway or set screws.
