Hydraulic System
IMPORTANT: When sliding the rod and piston assembly
in the tube, prevent the threaded end of the tube from
damaging the piston seal (Fig. 8-89, 14). Keep the rod
centered within the tube to help prevent binding.
13. Carefully insert the rod (Fig. 8 -89, 6) with all
attachments straight into the tube (4). Use a pin
spanner wrench begin to thread the head gland into
the tube. Install new locking inserts (9) into the head
gland. Continue to thread the head gland into the
tube and torque to 300-400 lb/ft (407-542 Nm).
Remove the compression tool.
14. Install new oiled o-rings and back-up rings on the
pilot check valves (Fig. 8-89, 5). Lubricate the valve
and rings with clean, filtered hydraulic oil. Install and
torque to 30-35 lb/ft (41-47 Nm).
15. If necessary, install both grease fittings (Fig. 8 -89, 2)
into their threaded holes in the cylinder tube eyelet.
16. Test the side tilt cylinder at low operating pressure
[100 psi (6,9 bar)]. Verify that the piston and rod
move freely in both directions.
17. Increase the operating pressure to the maximum for
the cylinder [1750 psi (120 bar)]. Verify that the
piston and rod move freely in both directions.
18. Retract the piston fully and cap the hydraulic hose
ports. Install the cylinder on the carriage. Lubricate
the self-aligning bearing (Fig. 8 -89, 3) via the grease
fittings (2) with multi-purpose grease before
operating the side tilt carriage on the vehicle.
