Using a chain pin generally refers to either removing a chain pin to break a chain or installing a new one to connect a chain, typically on a bicycle. The reference focuses on using a chain tool for this purpose. Here's a breakdown of how to use a chain pin, assuming you're working on a bicycle chain:
Using a Chain Tool to Remove or Loosen a Chain Pin
A chain tool is used to push chain pins in and out. Chain tools usually have two slots for chain placement.
- Outer Slot: Used for disconnecting and reconnecting the chain.
- Inner Slot: Used for loosening tight chain links.
Steps to Break a Chain (Removing a Pin)
-
Position the Chain: Place the chain in the outer slot of the chain tool. Make sure the pin you want to remove is aligned with the driving pin of the tool.
-
Drive the Pin: Turn the handle of the chain tool to push the driving pin against the chain pin.
-
Push the Pin Out: Continue turning the handle to push the chain pin partially or fully out of the chain link. The YouTube video reference highlights this process as disconnecting the chain. Important: Do not fully remove the pin unless necessary, as it can be difficult to re-insert.
Steps to Loosen a Stiff Chain Link
-
Position the Chain: Place the chain in the inner slot of the chain tool.
-
Drive the Pin: Carefully turn the handle to slightly push the pin. The goal is to loosen the link, not to remove the pin entirely.
Connecting a Chain with a New Chain Pin
Connecting a chain usually involves either using a master link or re-inserting a chain pin (often a connecting pin specifically designed for this purpose). Here's the general process:
-
Align the Chain Ends: Bring the two ends of the chain together, ensuring they are properly aligned.
-
Insert the Connecting Pin:
If using a standard connecting pin, use the chain tool (outer slot) to carefully press it through the link plates. These pins are often designed to be broken at a specific point after insertion to ensure the correct length.
*If using a master link, follow the manufacturer's instructions, as these usually clip together by hand or with pliers. A master link is a special type of chain pin for easy assembly. -
Break off Excess (If Applicable): If using a connecting pin that requires it, use pliers or the appropriate tool to break off the excess length of the pin.
-
Check for Smooth Movement: Ensure the newly connected link moves freely. If it's stiff, use the chain tool (inner slot) to slightly loosen it, as described above.
