    Note: Install the hose clamp on the hose assembly before connecting the hose assembly to the head end of the cylinder assembly. Do not tighten the hose clamp at this time.

  1. Use spacer (43), grommet (53), clips (51) and (52), and bolt (56) in order to attach hose assembly (49) to the cylinder assembly.

  1. Remove support under carriage assembly (33). Raise or lower the carriage assembly in order to align the holes in the cylinder rod eyes with the holes in link assembly (26). Connect the cylinder to carriage assembly (33) with fittings (21), pins (27), bar (28), bolts (29), and washers (34). Tighten bolts (29) to a torque of 120 ± 20 N·m (90 ± 15 lb ft).

    Note: Insert pins (27) into carriage assembly (33). Be sure that the holes in the pins and the holes in the carriage assembly are aligned horizontally.

  1. Tighten all hose clamps. Check all connections for leaks and make repairs, if necessary.

  1. Check the oil level in the hydraulic tank and fill the tank, if necessary. Cycle the cylinder in both directions in order to purge air from the lines and from the cylinder. Refill the hydraulic tank to the FULL mark.
