5-2 Lower Mechanism: Travel Drive Unit 9.) Assembling the brake piston (1-15) Assemble the D-rings (1-16, 1-17) onto the brake piston (1-15). With the side with the larger diameter of the brake piston (1-15) up, assemble it onto the flange (1-1). Note: a.When installing the D-rings (1-16, 1-17), generously apply grease on the rings. b.Using a positioning jig, align the knock pin holes of the base plate (1-2-1) on the flange (11) and the brake piston (1-15) so that they are arranged in line, and then assemble the brake piston (1-15). c.When assembling the brake piston (1-15), apply grease on the external surface and inside the bore of the flange (1-1). d.Assemble while evenly pressing down the brake piston (1-15) so that it may not incline. Assembling the piston as inclined may cause operational failure or ripping of a D-ring.
10.) Assembling the spring (1-18) Assemble the springs (1-18) into the bores (at eight locations) provided for assembling the springs (1-18) on the brake piston (1-15).
