CHAIN MAINTENANCE
Although both chains are lubricated,
it
is advisable to remove the rear chain at
intervals and thoroughly clean and re-grease (See below).
Cleaning and Greasing the Rear Chain. Remove all external dirt by brushing
vigorously with a wire brush. Soak the chain in
a
parafin bath, moving
it
about until
the joints are washed clean. Finally rinse in clean paraffin and leave to drain and dry.
The chain after drying will then be ready for lubricating. Immerse the chain in
a
bath
or
grease which has been melted over a pan of boiling water. The chain should
remain in the bath for five to ten minutes, being moved about freely to ensure
penetration of the grease into the chain bearings. Allow the grease to cool to its
normal state, then take the chain out of the bath, wipe off the surplus grease and
replace the chain on the machine. When fitting the spring clip fastener on the
connecting link, care must be taken to ensure correct fitting. The fastener is
roughly the shape of a fish, and, if
it
is remembered that a fish swims nose
first
and
the fastener is fitted so that the nose (closed end)
is
always proceeding
in
the forward
direction when the machine is running, the fitter will have an easy aid to memory.
It
is
a
good plan to carry out this cleaning and greasing service at the beginning of the
winter, half-way through the winter and
at
the commencement of the summer.
