When the engagement among chain and sprockets becomes defective or any component that brings about excessive decline during the strength on the chain happens, exchange the whole chain. When any on the following problems come about during the chain you use, exchange the whole chain to keep security.
When a chain is worn near to the “Elongation restrict of chain” .
?When a flaw or crack takes place in the plate.
?When a flaw or crack or defective rotation of a roller is observed.
?Whenever a chain link is stiff.
?Whenever a pin is rotated.
?When a pin is bent or otherwise deformed or when a plate is critically warped.
?When rust buildup prevents smooth bending of the chain.
?When diluted sulfuric acid or any other corrosive materials is deposited.

Replacement of sprockets and just how to order
The daily life of sprockets is generally several times the lifestyle of a chain, but when the teeth are worn for the reason that of insufficient lubrication or damaged simply because of a shock 
load, and so forth., the sprockets needs to be replaced.
?When placing an purchase, please specify the following when the chain No. is identified.
one. Chain No. and variety of strands
2. Type of sprockets
3. Shaft hole diameter (d) (This is not necessary if you drill this hole; in this instance, drill a hole not exceeding the utmost shaft hole diameter.)
4. Number of teeth
5. Hub diameter (DH) and length (L) (during the situation of non-standard sprockets)
6. Whether the tooth heads are hardened
Specify the following items, should the chain No. is unknown
1. Tooth thickness (T)
two. Root diameter (DB) (Caliper diameter (DC) while in the situation of odd-number teeth)
