Maintenance and Adjustment
Chain and Sprocket Wear Inspection
1. Measure across 20 links
2. Weight
Stretch the chain taut by hanging a
10 - 20 kg weight on the chain.
Measure the length of 20 links on the
straight part of the chain from pin centre of
the 1
st
pin to the pin centre of the 21
st
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.
If there is any irregularity, have the drive
chain and/or the sprockets replaced by an
authorised Triumph dealer.
2
The use of non-approved chains may result
in a broken chain or may cause the chain
to jump off the sprockets.
Use a genuine Triumph supplied chain as
specified in the Triumph parts catalogue.
Never neglect chain maintenance and
always have chains installed by an
authorised Triumph dealer.
If the sprockets are found to be worn,
always replace the sprockets and drive
chain together.
Replacing worn sprockets without also
replacing the chain will lead to premature
wear of the new sprockets.
