the pinion and weld the first
threaded bush onto the gate as
shown in Fig. 16.
4) Slide the gate manually making sure that the rack rests on
the pinion. Weld the second and third bushes.
5) Position another rack element next to the first and use a
section of rack to set the teeth of the two elements in phase
as shown in Fig. 17.

bushes. Proceed in this manner until the rack covers the
entire length of the gate.
