No.
If you have two chain rings you already have a front derailer, which will do the job of a chainguide.

In a Motive Gear application guide, these are referred to as internal kits.
On a bicycle, as seen from the right(drive) side, the chainwheel(s) and the sprocket(s) and the chain will be rotating clockwise. If the bike has a rear derailer the tension pulley will also be rotating clockwise while the guide pulley will be rotating counter-clockwise. If the bike has an internally geared hub the gears inside there can rotate in different directions (or not at all) depending on what gear the bike is in.
Installing a chain link fence can be a time consuming but rewarding task. A great how-to guide is available online at www.yourfencestore.com/cl/clinstall.
How do you adjust timing chain on a 1990 sentra?
Very important. Without it, the chain could fall of. Also it keeps tension on the chain for correct timing.
Yes, its actually a chain that looks like a motorcycle chain. It goes around a set of gears and has a spring loaded tensioner made with plastic. The tensioner looks like a small curved lever with a guide for the chain to run over and a coil spring around its bolt to provide the tension. After many miles, like 120-150K, the chain stretches and the tensioner wears out. The first symptom is a ticking noise that sounds like a valve tap and rough idle. The noise is the loose chain slapping the front case cover. I just had mine changed for a cost of around $800. You have to remove everything on the front of the engine and then drop the oil pan to remove the front cover which adds to the cost. You also must change the chain, gears and tensioner assembly at the same time, it comes as a set.
OK... there is a lot of confusion on the belt/chain thing. How your able to tell on any vehicle is to look at the timing cover, which is located behind your accessory drive belt(s). If the cover is plastic then you have a belt, if it is metal (usually aluminum or steel) then it is a chain. The reason for this is that a chain needs to be oiled where a belt does not. And if there is oil present then it has to have a tight seal so it doesn't leak. A belt just needs to be free of dirt and moisture so a plastic covering with a gasket works just fine. I have known this to be true with every car I have touched in the last 20 years. Now there are some cars that have multiple chains, not too many people know this. They are usually found on vehicals that are V-shaped motors with DOHC's (but not all of them). The main chain runs around the crank and the 2 intake cams then there are secondary chains that runs from 1 of the intake cams to the exhaust cam (example...Nissan 350zx). These timing covers are also metal. Now with all that cleared up, your Focus has a timing chain and they are typically changed around 120,000 miles. The guide and the tensioner are usually what wears out making the chain loose and slip off the timing gears. But "rule of thumb" is change the Guide, Tensioner, Chain, Cam and Crank gears as all the parts wear together (don't change the chain and not the gears). You will hear some people say that they don't need changing which is true to a minimal extent. With the chain and gears being metal they are designed to last a really long time but however the guide and tensioner are made up a composite nylon/plastic material that does wear out (again usually about 120,000 miles). And back to the "rule of thumb" change everything together. Come to think about all this information, what is the exact question your asking?
I most likely corresponds to the chain's drive pitch or gauge or another special characteristic of that specific chain. First figure out who makes the chain, then consult a guide to their markings, usually available on their website.
Not recommended.
Self propelled lawn mowers have gears or chain links attached on the axles that mesh with drive gears mounted on a shaft connected to the engine crankshaft. They move by themselves at a steady speed. The rate of speed on some models can be set by the operator at slow, medium or fast depending on how fast the operator wants to walk and guide the mower at the handle bars. On steep climbs they are easier on the operator because with a normal walk behind the operator has to push and guide the lawnmower from the handlebars.
who replaced the chain guide because it sounds like the timing might be off a bit like it skipped a few teeth when the guide broke from the slack.
