#40 Chain Breaker Tool

The 40 Chain Breaker Tool is an essential shop and trackside tool for anyone working with #40 roller chain used in quarter midgets, go-karts, and other racing or power transmission applications. Designed to quickly and cleanly remove chain pins, this tool allows racers and mechanics to break, shorten, or repair #40 chain with precision and minimal effort.

Using a threaded drive pin mechanism, the tool pushes the riveted pin out of the chain link, separating the chain without damaging surrounding links. This makes it easy to remove worn sections, adjust chain length for gearing changes, or install new chain segments. Chain breaker tools are commonly used when replacing or resizing chains, ensuring the chain length matches the exact setup needed for optimal performance.

Built for durability and repeated use, a chain breaker is typically constructed from hardened steel to withstand the force required to press out riveted pins. Its compact design makes it convenient for both garage maintenance and trackside adjustments, helping racers keep their drivetrain in top condition.

The #40 chain standard is widely used in karting and racing equipment due to its strength and reliability, making the correct chain tool a must-have for any race team’s toolbox. With a proper chain breaker, chain maintenance becomes faster, cleaner, and more accurate than attempting to remove links with improvised tools.

Perfect for quarter midget racers, karting teams, and performance mechanics, the 40 Chain Breaker Tool makes drivetrain maintenance simple and efficient so you can spend less time in the shop and more time on the track.
