Installing the Spring and End Cap
1.
For XL 1127 to XL4581 place the retractor plate on top of the piston.
2.
Insert the springs (26/27) into the face of the piston and then the end cap onto
the springs.
3.
Pass the correct Hytork retractor rod through the end cap (refer to Figure 4) and
screw it into:
—
For XL 26 to XL681 the pistons (20)
—
For XL 1127 to XL4581 the retractor plate
4.
Line up the end cap so that the safety symbol is correctly positioned for
easy reading.
5.
Prevent the “hold-nuts” to rotate by one wrench. Use another wrench, to screw
the adjusting nut on the Hytork retractor rod in until the end cap is completely
engaged in the body.
6.
It will be necessary to push the end cap into the body to overcome the
O-Ring compression.
7.
When the end caps are in place and the SAFEKEYS fitted correctly, remove the
Hytork retractor rods and replace the sealing bolts (28) and seals (29).
