MAINTENANCE AND ADJUSTMENT
112
To inspect the drive chain and sprocket
wear:
▼ Remove the drive chain guard.
▼ Stretch the drive chain taut by
hanging a 20 - 40 lb (10 - 20 kg)
weight on the drive chain.
▼ Measure the length of 20 links on
the straight part of the drive chain
from pin center of the 1st pin to the
pin center of the 21st pin. Since the
drive chain may wear unevenly, take
measurements in several places.
▼ If the length exceeds the maximum
service limit of 12.6 in (320 mm), the
drive 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.

▼ If there is any irregularity, have the
drive chain and/or the sprockets
replaced by an authorized Triumph
dealer.
▼ Reinstall the drive chain guard and
tighten the fasteners to 80 lbf in
(9 Nm).
