Maintenance
81
To inspect the chain and sprocket wear:
Stretch the chain taut by hanging a
10 - 20 kg (20 - 40 lb) weight on the
chain.
Measure the length of 20 links on the
straight part of the chain from pin
center of the 1st pin to the pin centre of
the 21st pin. Since the chain may wear
unevenly, take measurements in several
places.
If the length exceeds the maximum
service limit of 12.6 in (320 mm), the
chain must be replaced.
Rotate the rear wheel and inspect the
drive chain for damaged rollers, and
loose pins and links.
Also inspect the sprockets for unevenly
or excessively worn or damaged teeth.

Note:
• Illustration shows wear on
sprockets mounted on the left hand
side of the motorcycle. For
sprockets mounted on the right
hand side of the motorcycle, the
wear is on the opposite side of the
tooth.
If there is any irregularity, have the drive
chain and/or the sprockets replaced by
an authorized Triumph dealer.
