Piston Bonder

Torque Converter Rebuilding Systems

Jump to Section


The TCRS® piston bonder has a massive capacity to accommodate the increasingly larger pistons and front covers found in today’s torque converters. Thanks to its standard 10″ air cylinder, bonding the Allison 1000/2000 series lock-up pistons is not a problem for the TCRS® Piston Bonder. It’s fast too, with the ability to bond most lock-up pistons, up to 14″ in (36 cm) in diameter, including front covers every eight minutes or less on average.

Simply place the lock-up piston in the bonder and it heats, presses the clutch lining and automatically releases. The easy-adjust timer and dual temperature controls allow users to change bonding cycles quickly depending on the particular piston they’re working with. Aluminum bonder dies, not steel, allow you to heat faster, more evenly and eliminate hot or cold spots (28 in kit). Other dies are also available. A one-piece ring heater maintains even heat. TCRS®’ exacting specifications and quality manufacturing practices require high-quality pneumatic components. An optional storage cart for the dies doubles as a stand for the piston bonder.
