• 1. For roller chains with RP body pin type, grind down one end (on the same side) of the two pins on outer link until they are flush with the plate.
  Avoid overheating the chain when grinding.
  Poly-steel chain do not have rivets, and there is no need to scrape them off.
  RS08B-1 to RS16B-1 use pins with simple cut and connect specifications. There is no need to scrape off the pin fastening rivet.
• 2. For roller chains with a CP body pin type, remove the cotter pin or other fastening parts.

• 3. Pass the roller chain through the groove in the chain vise, and lightly tighten the roller of the part to be disassembled with the jaws of the chain vise.
  Poly-steel chain and Lambda Chain, please follow the procedures in sections 1.3 and 1.4.
  For multiple strand Super chain, pass the lowest roller through the jaws of the chain vise.

• 4. Place a primary punch that matches the size of the roller chain on the head of the pin that you have just cut, and hit the head of the primary punch with a hammer.
  At this time, alternately strike the pair of pins on outer link so that they come out parallel to each other. Continue striking until the pins are just about to come out of the outer plate.

  Figure 4. Hitting the pin with the primary punch

  
• 5. Use a secondary punch and hammer to remove the pair of pins from the outer plate.

• 1. For roller chains with RP main pin type, grind off one end (same side) of the two pins on outer link with a grinder (same procedure as in 1.1).
  For roller chains with a CP body pin type, remove the cotter pin and other fastening parts.
• 2. Remove the two pins from the same outer link.

  Figure 5. Cutting with a chain screw

  

• 1. Support the outer plate of the chain on the support, hold the head of the pin with the special punch, and lightly hit the head of the punch with a hammer.
• 2. Apply a large amount of force to Inner link to prevent damage.

• 1. For roller chains with RP main pin type, grind off one end (same side) of the two pins on outer link with a grinder (same procedure as in 1.1).
  For roller chains with a CP body pin type, remove the cotter pin and other fastening parts.
• 2. Use the cradle and dedicated punch of Lambda Chain cutting tool to cut the chain. The cutting method is as described in section 1.1, except that the dedicated cradle is used instead of the vise.
• 3. When removing the pin with a punch, tap it gently alternately to remove it.

When connecting roller chains, it is convenient to use the sprocket teeth. Follow the steps below.

• 1. Wrap the roller chain around the sprocket so that both ends of the roller chain are on the sprocket.
• 2. Insert the connecting link into the joint.
• 3. Insert connecting link plate and then secure it with a fastening part such as spring clip, split pin, or spring pin.
• 4. For F-type connecting links, lightly tap connecting link plate with a hammer to insert it into the specified position, then secure it with a fastening part such as a spring pin.
• 5. Protect the sprocket teeth from being struck by hammering, etc.

Figure 8. Joining at the sprocket

This is a method when sprocket teeth cannot be used due to layout restrictions.

• 1. Wind the roller chain around the sprocket and pull both ends of the roller chain with Chain Puller (see accessories) or wire.
• 2. Insert the connecting link into the joint.
• 3. Insert connecting link plate and secure it with fastening parts such as spring clip, split pins, or spring pins.

Figure 9. Joining shafts

1. spring clip

spring clip are primarily used on connecting links of roller chains RS60 and below.
When connecting, insert the connecting link plate onto the pin, then securely insert spring clip into the grooves of the two pins on the connecting link.

If spring clip is stretched too far, it will not insert properly and will fall off.

spring clip should generally be attached in the direction of the roller chain movement as shown in Figure 10.

Figure 10. spring clip installation direction

2. Cotter pin

With the exception of some environmentally resistant and special Drive chain Drive chain the split pins used are heat treated.

The split pin should be opened at an angle of about 60°. Do not reuse split pins or use commercially available split pins.
