Maintenance And Adjustment
102
To inspect the chain and sprocket wear:
Remove the chain guard.
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
centre 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 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 authorised Triumph
dealer.
Refit the chain guard, tightening the
fixings to 9 Nm.
