General Information
There are a number of industrial silent chain manufacturers in the United States and each produces different types of silent chain. Chains from different manufacturers differ in design and therefore should not be interconnected, nor should their parts be interchanged. These instructions illustrate and describe the procedures for connecting and disconnecting some of the most common silent chains. For information on chains not shown here consult the manufacturer.
Safety
Serious personal injury can result if safety rules are not followed. Observe the following safety precautions when installing a chain:
*Shut off power to the equipment and lock out the power switches before installing chains.
*
Always wear safety glasses to protect your eyes.
*
Wear protective clothing, gloves, and safety shoes as appropriate.
*
Support the chain to prevent uncontrolled movement of the chain or parts.
*
Restrain shafts and sprockets from free rotation where such rotation could permit uncontrolled chain movement and cause personal injury or equipment damage.
*
Use pressing equipment to remove or install press fit pins or link plates. Keep tooling in good condition and use it properly. If pressing equipment is not available contact the chain manufacturer for additional guidance.
*
Know and understand the chain construction, including the correct direction for pin removal
and insertion, before connecting or disconnecting a chain.
Connecting Side Guide Chain

2. Insert a drilled connecting pin.
3. Insert a short pin next to the drilled pin, making sure that the convex pin surfaces are facing.
4. Secure the drilled pin using a roll pin.
