SKU MIRBB-86
MIRA BB-86 Counterbore Unit for recutting diesel sleeve counterbores
The BB-86 is a portable and easy-to-operate tool for recutting diesel sleeve counterbores in engine blocks. To ensure a proper seal between the engine block and wet liners, the counterbore seat must be refaced during engine overhaul or in the event of leaks. The unit centres automatically on the engine block and is secured by a strong electromagnet, ensuring that the refaced counterbore seats are automatically parallel to the sealing surface. The operation can be performed on installed or removed engine blocks, as well as on built-in underfloor engines. The BB-86 is available in three sizes based on inside magnet diameter: Mini (154 mm), Standard (170 mm), and Giant (198 mm), plus an Extension variant for depths up to 200 mm. Each unit is supplied complete with a turning handle, service tooling, instruction manual, and a wooden storage box. A wide range of MIRA cutting tools (MB85–MB139) covering bore diameters from 73 mm to 220 mm are available for use with the unit.
