The BlueSpot Motor Cycle Chain Breaker is designed for the repair, splitting, and riveting of new and old motorbike chains. Manufactured from hardened, heat-treated steel, this tool is suitable for use on chain pitches from 35 to 630. It features removable pin guides for improved accuracy and can be used on engine timing chains. The set includes three push pin sizes (2.2, 2.9 & 3.8mm) for various chain pitches, allowing for the removal and replacement of rivets. The square design enables it to be bolted to a work surface, fastened in a vice, or held by hand. The handle winds the push pins to remove rivets from chain links for alteration, and the same action is used to replace rivets with the use of the adaptor press plate and riveting and pin anvil. Heavy-duty chains may require grinding off pinheads before breaking. Rivets and consumables are sold separately. The kit comes in a handy carrying case for storage. To activate the manufacturer's lifetime guarantee, register the product on the BlueSpot website within 30 days of purchase.
