Description

EC #40 Chain Breaker Tool – Heavy-Duty Rivet Extractor for #40 Roller Chain


The EC #40 Chain Breaker Tool is a professional-grade chain rivet extractor and installer, designed to make cutting and reassembling #40 roller chain fast, clean, and secure. Whether you're adjusting chain length or performing drivetrain maintenance, this tool delivers the durability and precision needed for racing go-karts, industrial machinery, and other high-torque applications.


Unlike lighter tools that may bend or break, the EC 40-1R-BK is built to punch out chain pins cleanly and rivet them back in place, eliminating the need for weaker master links. It’s the go-to tool for racers and mechanics who need a reliable way to modify #40 pitch chain.


Note: This tool is designed exclusively for #40 pitch roller chain. It will not fit #41, #415, #420, or #428 chains due to size and width differences.


Key Features:

  • Precision-built for #40 pitch chain (1/2" pitch, 0.312" roller width)
  • Heavy-duty steel construction for long-term reliability
  • Cleanly removes and re-rivets chain pins without damage
  • Ideal for racing applications, industrial use, and custom builds
  • Compact and easy to use in the shop or on the go

Why Use a Chain Breaker Instead of a Master Link?

Master links are convenient but can be a weak point in high-stress applications. A proper riveted connection provides superior strength, making chain breakers a must-have for racing, off-road, or industrial environments where reliability is critical.

FAQ

1. What chain sizes does the EC #40 Chain Breaker fit?

This tool is specifically designed for #40 pitch roller chain only. It will not work with #41, #415, #420, or #428 chains due to size and width differences.
