SHACMAN F3000 / X3000 / M3000 / H3000 Balance Shaft Housing DZ97259520911
FUNCTION
1. Housing and Protecting the Balance Shaft Assembly: Serving as the "casing" for the balance shaft, it houses internal components-such as the balance shaft itself, bushings, bearings, and seals-thereby shielding these precision parts from external contaminants (such as dirt and grit), physical impacts, and corrosion.
2. Supporting the Rear Suspension Balancing System: It securely anchors the stabilizer bar (balance shaft), enabling the left and right rear axle assemblies to articulate vertically with relative independence; this ensures that all four wheels remain in contact with the ground when traversing uneven terrain, thereby facilitating an even distribution of load.
3. Transmitting Forces and Torque: It reliably transmits the weight of the rear axle, road impact forces, and torque loads to the vehicle frame, while simultaneously dampening a portion of the resulting vibrations.
4. Maintaining Suspension Geometry: It ensures the precise positioning of the balance arms and the rear axle assembly, thereby preventing deformation or instability within the rear suspension system.
Installation Location
It is installed within the vehicle's rear suspension balance shaft assembly, specifically situated above the rear axle and beneath the frame side member; it serves as a core housing component of the rear suspension balancing system.
Working Principle
The balance shaft housing is a large cast-iron casing featuring an internal cavity designed to accommodate the balance shaft assembly. As the vehicle travels, the rear axles undergo vertical displacement in response to impacts from uneven road surfaces; within the housing, the balance shaft rotates or oscillates-facilitated by bushings and bearings to ensure smooth movement-while the housing simultaneously distributes these forces evenly to the vehicle frame and balance arms, thereby fulfilling the dual functions of balancing the left and right rear axles and dampening vibrations.
Advantages
| Actual Application Effects | Specific Performance (for SHACMAN Delong X3000 / M3000 / F3000 Heavy Trucks) |
|---|---|
| Improved heavy-load stability | Effectively balances the load between the left and right rear wheels under full-load or overload conditions, reduces body roll, and improves passability on complex terrains such as mines, construction sites, and slopes. |
| Buffers road impacts | Absorbs and attenuates bumps and vibrations from the road surface, protects the chassis, rear axle, and cargo, and significantly reduces the failure rate of the rear suspension system. |
| Enhanced ride smoothness and comfort | Works with leaf springs or air suspension to reduce body shaking and driver fatigue, making long-haul transport more comfortable. |
| Extended component service life | High-strength cast iron structure is impact-resistant and wear-resistant, reducing wear frequency of balance shaft bushings, bearings, and other wearing parts, thereby extending the overall suspension system lifespan. |
| Enhanced driving safety | Prevents rear suspension failure, vehicle drifting, or loss of control caused by damage to the balance shaft housing, improving safety during heavy-load transportation. |

Maintenance Recommendations
| Maintenance Item | Recommended Interval | Specific Actions |
|---|---|---|
| Visual Inspection (Cracks, Deformation, Oil Leak) | Every 10,000 km or monthly | Check the housing for cracks, deformation, or oil seepage. Inspect bushings and seals for normal condition. |
| Bolt Tightening Check | Every 20,000 km | Check and re-torque all mounting bolts to the specified value. |
| Lubricant Level and Quality Check | Every 20,000 km | Check if the lubricant inside the balance shaft housing is sufficient, emulsified, or contaminated. Replace if necessary. |
| Balance Shaft Clearance Check | Every 30,000 km | Lift the rear axle and check for excessive play or sticking in the balance shaft. |
| Complete Rear Suspension Inspection | Every 50,000 km | Inspect the balance arm, leaf springs, U-bolts, and other related components. |
| Major Overhaul or Replacement Interval | Every 100,000–200,000 km or when damage appears | Shorten the interval under heavy-load or mining conditions. |
