Blade Lift Bar

Usage:

Remove Lift Bar

Start By:

a. remove centershift lock

1. Lower the blade to the ground.


Typical Example

2. Fasten a hoist to centershift cylinder (8). Remove the bolts and cap (7) from the cylinder. Remove the insert and the shims from the ballstud. Move cylinder (8) free of the blade lift bar (3). Remove the insert from the rod end of the cylinder.

3. Remove the bolt and clip (6) from the lift bar.

4. Fasten a hoist to the lift bar.

5. Remove bolts (1) and lock (5) from each end of the lift bar. Remove pins (2) and (4). Remove the washers from between the lift arm and the lift bar.

6. Remove blade lift bar (3). Weight is 115 Kg (253 lb.). Move the lift bar out toward the rear of the machine. Lower it to the ground. Move the hoist free of the frame. Remove the lift bar out the side of the machine.


Typical Example

7. Remove the seals and the bearings from each end of the lift bar with tooling (A).


Typical Example

8. Remove seal (9) from the lift bar. Remove snap ring (10). Remove two bearings (11) and the spacer from the lift bar with tooling (A).

Install Blade Lift Bar


Typical Example

1. Install new bearings (11) in each end of the blade lift bar with tooling (A). Install the bearings to a depth of 10.31 ± .406 mm (.406 ± .016 in.) from the outside surfaces of the lift bar.


NOTICE

Tooling (B) must be used to install the bearings to prevent damage.


2. Install the four new seals in each end of the lift bar with tooling (A). Install with the lip of the seals toward the outside of the bore. Install the seals even with the outside surfaces of the lift bar.


Typical Example

3. Install the snap ring in the centershift lock bore of the lift bar. Install the two bearings and the spacer between the bearings with tooling (C). Install the bearings and the spacer so they make contact with the snap ring.

4. Install a new seal in the centershift lock bore of the lift bar with tooling (A). Install the lip of the seal toward the outside surface. Install the seal so it makes contact with the snap ring.


Typical Example

5. Fasten a hoist to blade lift bar (3). Put it in position on blade lift arms (12). Install the washers between the lift bar and the lift arms. Install the two pins that hold the lift bar. Make sure the grooves in the pins are in alignment with the openings in the lift arms.

6. Put the locks in position in the openings in the lift arms. Install the bolts that hold the locks.


Typical Example

7. Fasten a hoist to centershift cylinder (8). Put it in position on ballstud (14). Put the inserts in position on cylinder rod (13) and cap (7). Put cap (7) in position on the ballstud. Install the bolts that hold the cap to the cylinder rod.

NOTE: Install 5P0960 Multipurpose Grease on the inside surfaces of the inserts and the ballstud.

NOTE: Refer to Remove and Install Ball and Socket Joint.

8. Put clip (6) in position on the lift bar. Install the bolt that holds it.

End By:

a. install centershift lock
