The apparatus to insert and remove the mounting bolts (10) in the openings (5) of a housing (1) of a sieve exchange unit, for a filter change, has a supply of external heat to expand the openings. The bolts are pressed through their enlarged openings with reduced resistance. Preferred Features: The outer zone of the housing is defined by its outer surface on one side and a limit surface on the other side, which is central between the outer surface and the opening wall. The heating system is a heated plate or strip, a heating channel system (4) or a heated cartridge. The bolts are cooled along their longitudinal axis, to prevent expansion. |
