Selecting the right option

For ASA chain the number is the pitch in eighths of an inch: 40 is 4/8 in (1/2 in), 60 is 6/8 in (3/4 in), 100 is 10/8 in (1-1/4 in). The figure after the dash is the number of strands.

This is KCM standard (carbon steel) chain. Step up to H-type where loads are heavier, or to stainless steel, nickel plated or self-lube chain where the environment or lubrication calls for it.

Fitting and use

KCM's power transmission tables note that chain with an offset link transmits 80% of the tabulated power.

KCM says not to replace damaged parts of a chain with new ones. Replace the whole chain, and check the sprockets when changing chain.

Check that a safety cover is fitted before running a chain drive.
