Drive Chain And Sprocket Wear Inspection - Triumph Street Triple S 660 cc Owner's Handbook Manual

Maintenance
Drive Chain and Sprocket Wear
Inspection
Warning
Never neglect drive chain maintenance
and always have drive chains installed
by an authorised Triumph dealer.
Use a genuine Triumph supplied drive
chain as specified in the Triumph Parts
Catalogue.
The use of non-approved drive chains
may result in a broken drive chain or
may cause the drive chain to jump
off the sprockets leading to loss of
motorcycle control or an accident.
If the sprockets are found to be worn,
always replace the sprockets and drive
chain together.
Replacing worn sprockets without also
replacing the drive chain will lead to
premature wear of the new sprockets.

To inspect the drive 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 319 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
unevenly or excessively worn or
damaged teeth.
• 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 4 Nm.
