580753410 (020237-0) Craftsman Pressure Washer - Overview

I loosened the rear motor mounts which protrude through slots in the frame using a 15mm open end allowing the engine to be moved enough to pass the front mounts through both the frame and the engine mounting holes. The upper bolts on the front mounts don't have enough clearance for a socket or box end and the open end gets less than a quarter turn at a time unless you remove the wheels. I just took my time and tightened the nuts being careful not to round the corners. The lower bolt/nuts present no problem.
