The brake group contains springs that are under compression. To prevent possible personal injury from flying parts, the brake group must be disassembled exactly as the following steps describe. Do not remove bolts (3) until after bolts (5) are slowly loosened and removed.
1. Remove four bolts (2) and plate (1) from the steering clutch and brake assembly.2. Fasten a hoist and tooling (A) to brake group (4). Remove brake group (4) from steering clutch group (6). The weight of the brake group is 326 kg (719 lb.).
Bolts (3) and (5) hold a spring under compression. To prevent possible personal injury from flying parts, bolts (5) must be removed before bolts (3).
3. Loosen bolts (5) slowly and evenly to partially release the spring tension in the brake group. Remove bolts (5) and retainer (7) from the brake housing.4. Remove eight discs (12) and seven plates (11) from the brake housing.5. Turn the brake group over.6. Loosen seven bolts (3) slowly and evenly until the spring tension in the brake group is completely released.7. Fasten a hoist and tooling (A) to brake housing (14). Remove the brake housing from retainer (9). The weight of the brake housing is 84 kg (185 lb.).8. Remove two rings (15), two springs (16) and ring (17).9. Remove piston (13) from retainer (9).10.
