To inspect the drive chain and sprocket
wear:
• Stretch the drive chain taut by
hanging a 10 - 20 kg weight on the
drive chain.
• Measure the length of 20 links on
the straight part of the drive chain
from the pin centre of the 1st pin to
the pin centre of the 21st pin. Since
the drive chain may wear unevenly,
take measurements in several plac-
es.
• If the length exceeds the maximum
service limit of 321 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 une-
venly or excessively worn or
damaged teeth.
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 re-
placed by an authorised Triumph dealer.
Brakes
Brake Wear Inspection
Warning
If fitting new proprietary brand brake
pads, check that the carrier plate of
the brake pad is at least 4.5 mm thick.
Fitting brake pads with the carrier
plate less than 4.5 mm thick may result
in brake failure due to the possible loss
of the brake pad as it wears.
Brake pads must be inspected in ac-
cordance with scheduled maintenance
requirements and replaced if worn to, or
beyond the minimum service thickness.
If the lining thickness of any pad is less
than, 1.0 mm (0.04 in) (front) or 1.5 mm
(0.06 in) (rear), replace all the pads on
the wheel.
