Hook X on spring 1 is more closed than hook Y. Hook Y (the more open one) should be
inserted into hole Z in the lever of arms 2. First of all pass chain K welded to bushing 3
through the spring 1. Then hook Y on spring 1 to hole Z in the lever of arms 2. Hook the
9th link of chain K (counting from that welded to bushing 3) to hook X on spring 1. Hook
the last link V of chain K onto U-bolt 4, then hook the 24th link of chain K (the 6th from the
end) again by means of U-bolt 4 to hole J in the lever of arms 2. That described is the
standard assembly of chain K to spring 1. The figure shows the correct position of the
bushings with chain 3.
In this step use the following parts:
Position 1: 11-13 springs ø7-56x276 (ø0.27”-2.2”x10.87”)
Position 4: 11-13 U-bolts M8 (0.31”)
