2. Remove the nut, washer and roller (3) from lever assembly (4).
3. Remove the bearing from lever assembly (4) with tool group (B).
4. Remove bracket assembly (1), cap (5), the diaphram, adapter (6) and the gasket from cylinder assembly (7).
5. Pull boot (8) and rod assembly (9) from cylinder assembly (7).
6. Remove lockwire (16), plate (15), piston assembly (13), cup (12), spring and retainer assembly (11) and seat assembly (10) from cylinder assembly (7). Remove seal (14) from piston assembly (13).

Assemble Bucket Positioner Or Lift Kickout Master Cylinder
NOTE: When the hydraulic system is serviced use caution to prevent introduction of foreign material into the brake fluid. Damaged or worn rubber parts are an indication of other fluids in the system. Flush and clean the system with denatured alcohol or clean brake fluid.
1. Put clean brake fluid on the inside parts of the master cylinder at assembly.
2. Inspect the bore in the master cylinder. Use a brake cylinder hone to remove any rough areas or corrosion in the master cylinder bore. If the cylinder bore has deep scratches a replacement of the master cylinder is needed.
3. Make sure the master cylinder bore is clean. Install seat assembly (2) with the seal and the end of the seat that has the larger outside diameter toward the rear of cylinder assembly (1).
4. Install spring and retainer assembly (3) as shown. Make sure the retainer is installed on the small end of the spring. Install cup (4) with the open end toward spring (3).
5. Install seal (6) in the groove of piston assembly (5) and install the piston assembly as shown. Install plate (7) and lockwire (8).
| NOTICE |
|---|
Make sure lockwire (8) is fitted correctly in the groove of cylinder assembly (1) and piston assembly (5) moves back against plate (7). |
6. Install boot (9) on cylinder assembly (1). Install rod assembly (10) in the cylinder assembly and boot.
7. Install the gasket and adapter (12) in cylinder assembly (1). Tighten adapter (12) to a torque of 150 lb.ft. (205 N·m).
8. Install the diaphram and cover (11).
9. Put bracket assembly (13) in position and install the two bolts that hold it to cylinder assembly (1).
10. Install the bearing in lever assembly (14) with tool group (A) until the bearing is in the center of its bore.
