Checking Chain And Sprockets For Wear - Husqvarna TC 250 2010 Workshop Manual

Checking chain and sprockets for wear

Check chain wear as follows:
- turn the adjuster screws to stretch the chain taut;
- mark 20 chain links;
- measure distance "A" (centre distance between 1st and 21st link).
Check the transmission sprocket for damage or wear. When worn down like the
sprocket shown in the figure, it must be replaced.
Wheel misalignment causes abnormal wear, making the motorcycle
unsafe to ride.
Dirt caked on sprockets and chain collected while riding on muddy
or wet terrain increases chain tension. If you expect to ride on
muddy or wet terrain, slacken the chain a bit. Riding on muddy
terrain significantly increases chain and sprocket wear.
