SKU KRAVGX-21
VGX-21 Valve Seat Refacing Unit
The portable VGX-21 has been developed for specialised petrol and diesel cylinder head workshops. Accurate valve seat processing is achieved by means of a spherical spindle guide bearing and a hydraulic ball clamping system. Near-pressure-free centring and braceless fixing of the MIRA rotary head enables precise and concentric valve seats to be produced. The VGX-21 package includes the refacing unit itself, a DT1 toolhead for 21–45 mm diameters, 6 FD-type pilots, 6 SK-type formtools, an AV basic cylinder head support for wall mounting, service tooling, a manual crank handle, an instruction manual with formtool catalogue, and a wooden storage box. Optional accessories include alternative toolheads (DT05, DT2, DT3, DSD), an adjusting micrometer EM25–75, the VD-97 Vario Drive electronic drive unit, and the MUV-95 Multivac vacuum test unit.
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.
