How To Install Chain Connecting Link

Proper installation of your roller chain connecting link is essential for ensuring proper performance and preventing premature failures during operation. We created two diagrams below to demonstrate the correct way for installing a chain connecting link.

Installing Spring Clip Connecting Link

During clip connecting links utilize a spring clip as a retaining method for holding the exterior side-plate onto the link. They are designed with unique pins that are grooved to accept the install of a spring clip. Take a look at the above diagram for a visual as to the proper way to install a spring clip connecting link. The clip itself should be installed to where the opening is facing in the opposite direction of travel, this prevents the clip from coming off due to debris or "catching".
Note: It is imperative to not spread the opening of the clip too far apart as it can degrade the action of the clip and weaken its holding power.

Installing Cottered Connecting Link

Standard cottered connecting links utilize two cotter keys as a retaining method for the exterior side plate, with the exception of API cotter connecting links, these use a J-hook cotter and should follow the same installation directional guidelines as a spring clip installation. Cottered style connecting links are capable of traveling in both directions and should have a 60° leg-spread angle for optimal retaining as the diagram above shows.
Note: Never attempt to re-use cotters that have previously been used and never use commercial cotters because they typically are not hardened or as strong as the cotters we supply with our connecting links.
