• Design: Directly interchangeable with the original equipment housing, ensuring a perfect fit and seamless integration with the vehicle’s powertrain system.

Core Function

• Provides a rigid enclosure for the clutch assembly and flywheel, protecting them from dirt, debris, and external damage.

• Maintains precise alignment between the engine crankshaft and transmission input shaft, ensuring smooth power transfer and reducing wear on clutch components.

• Serves as a mounting base for the starter motor and other powertrain accessories, ensuring their stable operation.

Flywheel Housing D02C-101-34+B SHANGCHAI – Premium Engine Component for Heavy-Duty Applications

When your fleet depends on uninterrupted power delivery, the flywheel housing isn’t just a cover — it’s the structural backbone that marries your engine to the transmission. The Flywheel Housing D02C-101-34+B for SHANGCHAI diesel engines delivers precision-machined alignment, robust vibration dampening, and long-service durability that keeps your trucks earning on the road, not sitting in the workshop.

Sourced directly from METTLEAD Truck Parts, this genuine-spec flywheel housing meets OEM dimensional tolerances and material standards, giving procurement managers the confidence of factory-direct pricing without compromising on fitment accuracy.

Key Features and Benefits

Engineered for Structural Integrity

• High-Grade Cast Iron Construction — Resists cracking under sustained thermal cycling and torsional stress, extending replacement intervals significantly.
• Precision-Bored Pilot Bearing Seat — Ensures concentricity within ±0.05 mm, preventing premature clutch and transmission input shaft wear.
• Integrated Mounting Bosses — Machined bolt patterns align perfectly with SHANGCHAI D-series engine blocks, eliminating field modification.

Performance You Can Measure

• Vibration Attenuation — The mass-optimized wall thickness absorbs harmonic resonance generated at high-torque operating ranges (1,200–1,800 RPM).
• Corrosion-Resistant Finish — Phosphate-coated surfaces resist moisture ingress in humid or coastal operating environments.
• Exact OEM Weight Balance — Maintains factory-calibrated rotational inertia, protecting crankshaft rear seals and bearings from uneven loading.

Procurement Advantages

• Factory-Direct Pricing — No middlemen. You deal with the source, keeping landed costs competitive.
• Rapid Lead Times — In-stock availability with dispatch within 3–7 business days for standard orders.
• Custom Packaging & White-Label Options — Ship under your own brand identity to your downstream customers.

Technical Specifications

Application Scenarios

The Flywheel Housing D02C-101-34+B SHANGCHAI serves as a critical drivetrain interface component across a wide range of heavy-duty commercial vehicles and industrial machinery powered by SHANGCHAI diesel engines:

• Heavy-Duty Trucks — SHACMAN F3000/X3000, SANY mining trucks, and CAMC heavy haulers equipped with SHANGCHAI SC-series powerplants.
• Construction Equipment — Wheel loaders, excavators, and concrete mixers relying on SHANGCHAI engines for sustained high-torque output.
• Bus & Coach Platforms — Intercity and transit buses using SHANGCHAI D-series engines where drivetrain alignment is mission-critical for passenger comfort.
• Generator Sets & Marine Auxiliary — Stationary and marine-rated SHANGCHAI engines where the flywheel housing also serves as the PTO mounting interface.

Whether your vehicles haul aggregate across African mining roads or deliver goods through Southeast Asian logistics corridors, this flywheel housing is built to endure the punishment of real-world commercial operation.

Strict Quality Control

Every Flywheel Housing D02C-101-34+B undergoes a multi-stage inspection process:

1. Raw Casting Inspection — Ultrasonic testing for internal voids and porosity.
2. CNC Machining Verification — CMM (Coordinate Measuring Machine) checks on all critical bores and faces.
3. Surface Finish Audit — Roughness measurement (Ra ≤ 6.3 μm on mating surfaces).
4. Final Assembly Fit Test — Trial fitment against reference engine block and transmission bell housing.

Frequently Asked Questions

What is the function of the flywheel housing on a SHANGCHAI engine?

The flywheel housing D02C-101-34+B acts as the rigid structural link between the SHANGCHAI engine block and the transmission bell housing. It maintains precise crankshaft-to-input-shaft alignment, absorbs torsional vibration, and seals the flywheel cavity against dust, moisture, and debris ingress.

How do I verify that D02C-101-34+B is the correct flywheel housing for my engine?

Cross-reference the part number stamped on your existing housing or consult your SHANGCHAI engine nameplate data (engine model, serial number, and production date). The D02C-101-34+B fits SC-series engines with SAE #1 pattern transmissions. Our technical team can confirm compatibility if you share your engine details.

What causes flywheel housing failure in heavy-duty applications?

Common failure modes include fatigue cracking from misaligned transmission installation, thermal stress fractures near the starter motor bore, and corrosion-induced material degradation in high-humidity environments. Using an OEM-spec replacement like the D02C-101-34+B with proper torque values on mounting bolts prevents most premature failures.

Can this flywheel housing be used with non-OEM transmissions?

Yes, provided the aftermarket transmission uses a SAE #1 standard bell housing bolt pattern and pilot bore diameter. We recommend verifying concentricity with a dial indicator during installation to ensure alignment stays within the ±0.1 mm total indicator reading (TIR) specification.

What is the recommended installation torque for the flywheel housing bolts?

SHANGCHAI specifies mounting bolt torque between 90–110 N·m for M12 Grade 10.9 fasteners, applied in a star pattern sequence. Always use new lock washers or thread-locking compound as specified in the SHANGCHAI workshop manual for your engine variant.
