Travel Unit 12)Base plate attachment Attach O-ring (1-23) and the 4 O-rings (1-22) to the top surface of the flange (11). Attach the knock pins (1-19) to the base plate (1-2-1). Place the valve plate (1-21) mounting surface of the base plate downwards and tighten it to the flange with the hexagon socket head bolts (1-11). Cautions: a. Apply grease to the O-ring (1-23). b. Do not apply grease to the O-rings (1-22). c. Attach the knock pins with their tapered sections up. d. Attach the base plate after applying hydraulic oil to the valve plate surface and cylinder block (1-4-1) surface. e. Be careful that the valve plate does not fall because the valve plate mounting surface of the base plate is pointing down when the base plate is attached. f. Check the mounting position of the O-rings on the flange and the position of the holes for the oil path on the base plate to attach the base plate. g. Check the position of the knock pins mounted to the base plate, the spring (1-18) mounting holes on the base plate and the flange-side knock pin holes, and the spring positions to attach the base plate. h. When tightening the socket head bolts, screw in all of the bolts around the circumference evenly.
