To guarantee a perfect seal between engine block and wet liners, the counterbore seats in an engine block must be refaced during engine overhaul and in case of leaks. This job is rapidly and simply carried out with the portable and precise BB unit. Its centering is automatic and the unit is clamped by means of an electro magnet. As the unit is placed directly on the sealing surface of an engine block, the refaced counterbore seats will automatically be parallel with the sealing surface. The refacing procedures can be carried out on installed as well as on removed engine blocks or even built-in underfloor engines.
Supplied in wooden box. Tools have to be ordered seperately.
