1. A method of installing a cutting wheel (12) at a cutting wheel transmission (14) of a slurry wall cutter (10), wherein the cutting wheel transmission (14) and the cutting wheel (12) have fastening means (20, 22) for fastening the cutting wheel (12), positioned linear in a telescoping spatial relationship to at least two spacer elements (24) arranged at the cutting wheel transmission (14), said method having the steps:
guiding the cutting wheel (12) to the cutting wheel transmission (14);
aligning the cutting wheel (12) relative to the cutting wheel transmission (14) so that the fastening means (20, 22) are opposite one another, without contacting one another in so doing;
connecting one respective centering element (30) to the spacer elements (24);
aligning the cutting wheel (12) relative to the spacer elements (24) by means of the centering elements (30), with the fastening means (20, 22) not contacting one another; and
displacing the cutting wheel (12) to the spacer elements (24) by the centering elements (30) so that the fastening means (20, 22) come into engagement with one another.
