drive is often overlooked for its efficiency, when in fact it is an
extremely effective method of transmitting drive with up to 95% of the
power being transferred from one shaft to another. In addition to
efficient transmission, chain drive is also flexible and adaptable,
avoiding the need to cut special gears to change ratios, when off the
shelf products can be matched to most tasks, simply be changing sprockets.
drive chain of any vehicle is one of the most important components and yet
normally gets the least attention. The standard drive chain of older
motorcycles and cars are of the "Roller Chain" type. The chain consists
of two major parts, 1) the pin link and 2) the roller link.
links get their linear strength from the side plates that keep them
together. A "Heavy Duty" chain will have thicker, stronger side
plates and thus greater overall strength. The pin link is very simple in
design having only two rods or pins connecting the side plates. The roller
link is more complex, consisting of two hollow bushings connecting the
side plates surrounded by a movable roller.
are several types of drive chains to cope with everyday cycling,
industrial applications, to racing superbikes:
as described above.
similar to the standard but equipped with a rubber o-ring at each end
of the pin. This o-ring traps in lubricant and keeps out road grit and
moisture, thus prolonging the life of the chain.
these chains incorporate oil-impregnated sintered metal bushings
inside the rollers that gradually release oil to the chain.
Master link: most
vehicle chains are connected into a loop by a master link. This is a
single pin link with
pins that allow the attachment of a removable side plate. The side plate
is held in place by a spring clip.
Chain: some vehicles are equipped with an endless chain that does
not contain a master link but are connected back unto itself when
produced. These chains must be removed by removing the swingarm of the
more you care for your chain, the longer it will last. In this case
where high pressures are applied for short duration, lubrication is
important. After each run in adverse salt or dusty conditions the
final drive should be cleaned and lubricated.
the chain from the vehicle and soak in kerosene (I know gasoline will
also clean a chain but due to its fire potential, use kerosene).
road grime and slight rust is a problem, scrub lightly with a hard
bristle or metal brush.
the chain over the pan of kerosene and drip dry.
your way down the chain testing the rollers and flexibility between
each link. If you find links that will not flex
freely even after forcing them, the chain needs replacing.
the chain on the floor and measure out 1 foot. Grab the chain at each
end of this foot length and push the chain links together. Now pull
outward on the chain and note any change in its length. It is
recommended that this movement be no more than 1/4 inch. Check the
rest of the chain in 1 foot lengths. If the
slack is more than 1/4 inch for any foot, the chain should be replaced.
is commonly done by using one of the aerosol can chain lubes
available. CAUTION: if your chain is of o-ring
design, make sure the chain lube is compatible.
second way to lube your chain is by purchasing a can of solid lube.
This material has to be heated, melting the solid, and the chain
dipped in. The chain is hung over the can and allowed to drain and
harden. This form of lube is longer lasting and will protect your
chain the most.

the chain adjuster on your rear axel indicates that the chain needs
replacing, do so.

Whenever you check your chain, check your rear and drive sprockets also.
The teeth on both sprockets should be uniform and symmetric. If they
appear hooked or worn, they probably need replacing. Grant you, not
