Usage:
Start By:
a. remove blade lift cylinders
Typical Example
1. Remove bolts (6) and the lock from the blade lift arm. Remove pin (7) that holds the blade lift arm to blade lift bar (5).
2. Fasten a hoist to blade lift arm (4). Remove bolts (1) and the lock. Remove bolt (3) and plate (2) from the pin. Remove the pin that holds the blade lift arm to the frame. Remove the washers from between the blade lift arm and the frame.
3. Remove blade lift arm (4). Weight is 90 Kg (200 lb.).
Typical Example
4. Remove seals (8) and bearings (9) from the frame with tooling (A).
Typical Example
5. Remove bolts (11) and retainer (12). Remove the washers and the shims from under the retainer. Push yoke (10) out of the lift arm enough to fasten a hoist to it. Remove yoke (10). Weight is 18 Kg (40 lb.). Remove the washers and the seal from the yoke.
Typical Example
6. Remove two bearings (13) from the lift arm by putting a saw cut down the length of each bearing. Be careful not to cause damage to the inside surface of the lift arm.
7. Repeat Steps 1 through 6 for the other blade lift arm.
Install Blade Lift Arms
Typical Example
1. Install the small bearing in blade lift arm (4) with tooling (B). Install large bearing (13) in the lift arm with tooling (C). Install the bearings so they make contact with their respective shoulders.
Typical Example
| NOTICE |
|---|
Tooling (B) and tooling (D) must be used to install the bearings to prevent damage. |
2. Install new seal (14) on yoke (10) with tooling (C). Install washers (16) on the yoke. Fasten a hoist to yoke (10). Put it in position in the lift arm.
3. Install a new seal on retainer (6). Put shims (17), washers (15) and the retainer in position on the lift arm. Install the bolts that hold the retainer to the yoke. The shims are used to get .25 mm (.010 in.) maximum end clearance of the yoke. The yoke must rotate freely in the lift arm.
Typical Example
4. Install new bearings in the frame with tooling (B). Install the bearings to a depth of 9.53 ± 0.41 mm (.375 ± .016 in.).
NOTE: Lower the temperature of the bearings to -21° C to -32° C (-6° F to -25° F).

Tooling (B) must be used to install the bearings to prevent damage. |
Typical Example
5. Install four new seals (8) in the frame with tooling (A). Install the seals with the lip toward the outside and even with the outside surface.
Typical Example
6. Fasten a hoist to blade lift arm (4). Put it in position on the frame. Put the washers in position between the lift arm and the frame. Install the pin that holds the lift arm and the frame. Install the pin that holds the lift arm to the frame. Make sure the groove in the pin is in alignment with the opening in the lift arm. Put the lock in position in the lift arm. Install bolts (1) that hold it.
7. Put lift arm (4) in position in blade lift bar (5). Install the washers between the lift bar and the lift arm. Install pin (7). Make sure the groove in the pin is in alignment with the opening in the lift arm. Put the lock in position in the lift arm. Install bolts (6) that hold it.
8. Put plate (2) in its correct position on the pin. Install bolt (3) that holds it. Tighten bolt (3) to a torque of 130 ± 7 N·m (95 ± 5 lb.ft.).
