7. Remove The ChainCutting Chain

Once the countershaft sprocket is broken loose you can begin removing the chain. Clip-style master links are easy — too easy — to remove. Slip the clip free with a flathead screwdriver. Next, walk the removable plate off the pins by alternately prying the ends with a screwdriver. Eventually, the plate will pop free.

With endless chains or riveted master links, if you don’t have a chain breaker, a hacksaw will do the trick. If you have a chain breaker, you may or may not (depending on the strength of the breaker and the size of the chain) need to grind off the head of the roller pin. Usually, the midpoint between the two sprockets will be the most unobstructed place to break the chain.

Motion Pro’s Chain Cutter & Riveting Tool is about the best one around, though the company also sells less expensive units. Install the correct size breaking tip in the tool, making sure that the tip is withdrawn at least 2mm inside the alignment bolt. Center the pin in the tool and tighten down the alignment bolt with a 14mm wrench to hold the tool in position. Using the 14mm wrench, crank the extraction bolt so that it pushes the breaker tip and the roller pin out of the bottom of the tool. When the pin falls free, back the extraction bolt out until the tip is back inside the alignment bolt. Loosen the alignment bolt until the chain falls free. Repeat if necessary for a master link.
