Block of cylinders of an incomplete complete set

All interfaced details are picked up for dimensional groups, all gaps meet standards. On the block the cam-shafts which are not a part of this remkomplekt, the valvate mechanism, a head of the block of cylinders and hinged units are separately mounted. Costs of machining are minimum or are not required absolutely.
