DRIVE CHAIN ADJUSTMENT
Pull the chain to check
for wear.
Movement here should
be minimal
MAINTAINING THE DRIVE CHAIN
If the chain is not too dirty, the operation of lubrication
is normally sufficient to clean the chain.
When the accumulation of dirt on the chain (sand,
mud, asphalt particles or other foreign materials) is
excessive, the chain must be washed with a brush and
kerosene. After washing, the chain has to be dried by
towelling it off and hanging in the air.
To obtain good performance and long life, the chain
must always be kept well lubricated.
A lack of lubrication increases friction between chain
rollers and sprocket surfaces, resulting in an increase
in friction, therefore an increase in the working
temperature of the components. This will result in the
lubricant burning and becoming less effective,
therefore increasing chain wear.
Risk of injury
Excessive Chain Tension
An over-tight chain increases the working loads
between the pins and the rollers, overheating the
chain thus consuming the lubricant more rapidly.
This causes the chain to wear faster.
Moreover, if the motorcycle is ridden on rough
roads or trails, the chain is subjected to extremely
hard shocks by the up and down lever action of the
swinging arm. This can lead to premature failure of
the chain and damage to other parts of the
motorcycle.
Excessive Chain Slack
A chain that is excessively loose is subjected to
hard whiplash like vibration shocks during
acceleration.
This adds to the force applied to the chain, causing
the chain to jump over the sprocket teeth possibly
causing harm to the vehicle or rider.
