General Safety Information

WARNING

– To avoid serious injuries:

• Obtain and read the service instructions

carefully prior to installing the parts. Loose,

worn, or damaged parts may cause serious

injury to the rider.

We strongly recommend only using genuine

Shimano replacement parts.

• Read these Technical Service Instructions

carefully, and keep them in a safe place for

later reference.

NOTE:

• The CJ-8S40 cassette joint should only be

used with sprockets from 16T to 23T.

• When lubricating the chain or the sprock-

ets, be careful not to get any oil on the

rubber bellows or the rubber cover of the

cassette joint.

• For maximum performance we highly

recommend Shimano lubricants and

maintenance products.

• Parts are not guaranteed against natural

wear or deterioration resulting from normal
