IMPORTANT: The bearing must be installed in the bore of the piston rod as shown in Fig.10C.9.
Fig. 10C.8. Seating Gland with Lock Ring Fig. 10C.9. Cylinder Rod Bearing Installed
A. Cylinder Rod
B. Retainer Plate
C. Install Bearing with Slots Positions as Shown
7. If bearing (24) was removed, press the new bearing in the rod eye. Install new O-rings (23) into
bore of bearing (24). Install retainer plates (25 and 26). Torque the bolts to 130 [Nm].
8. If removed, install new cylinder bushings (2) onto cylinder housing yokes.
9. Install the cylinder manifold (9, Fig.10C.1) and tube (4) to the cylinder (7). Using wire, secure
the rod end (6) to the cylinder (7).
5. INSTALLATION
1. Attach a hoist sling to the blade lift cylinder (7, Fig. 10C.1) as was done in removal procedure
and position it in the lift yoke (3).
2. Check to be sure pins protrudes 3 [mm] from the machined surfaced of yoke caps (8).
3. Slip yoke caps (1, Fig. 10C.2), marked sides appropriately matched to lift yoke (2) A to A and B
to B.
4. Secure the yoke caps (8, Fig. 10C.1) to the lift yoke (3). Check to be sure that pins are still
engaged in the hole in the yoke bushings. Torque the mounting bolts with washer to 450 [Nm].
5. Secure the lift cylinders (7) to the frame with the cylinders hangers. Remove the hoist sling.
6. Connect the cylinder hoses (5) to the cylinder manifold (9).
7. Remove the wire securing the cylinder rod ends (6) of both cylinders to the cylinders (7). Start
the engine and extend the cylinder rods as necessary to connect rod pins (1) to the blade (2).
8. Disconnect the lift cylinder hangers from the frame and extend the cylinders rods until the eyes
line up with brackets on the rear of the blade. Insert the lift cylinder mounting pins (1) through
the bracket, aligning the lock hole in the pins with the lock holes brackets. Secure the pins (1)
with the locking hardware.
9. Vent the hydraulic system and add oil as necessary, refer to the OPERATOR'S MANUAL.
Visually check for oil leakage.
10. Cycle cylinder a few times. Recheck cylinder and cover bolt torque.
