Product Features

• Structure: A one-piece, high-strength alloy steel forging, with an integrated starter ring gear on its outer circumference. The center hub features precision-machined mounting holes for connection to the crankshaft, and the friction surface is hardened and ground for flatness.

• Performance: The alloy steel construction provides high inertia to smooth engine power delivery, while the hardened friction surface withstands the pressure and heat of clutch engagement. The integrated ring gear ensures reliable starter engagement.

• Design: Factory-balanced to minimize vibration, with direct-fit mounting holes for easy installation. The precision-machined friction surface ensures consistent clutch performance and long service life.

Core Function

• Stores rotational energy from the engine’s power strokes, releasing it during compression strokes to maintain smooth operation and prevent stalling at low RPM.

• Provides a friction surface for the clutch disc, enabling power transfer between the engine and transmission.

• Drives the integrated starter ring gear to crank the engine during startup.

Flywheel MC13 201-02301-6104 – Genuine SINOTRUK Engine Flywheel for Heavy-Duty Performance

When your MC13 engine demands uncompromising rotational stability and seamless power transmission, the Flywheel MC13 201-02301-6104 SINOTRUK delivers exactly that. Engineered to OEM specifications, this flywheel serves as the critical link between your engine’s crankshaft and clutch assembly — storing kinetic energy, dampening torsional vibrations, and ensuring smooth engagement every single time your driver shifts gears. Sourced directly from our factory supply chain, this part arrives at your warehouse faster, priced leaner, and built tougher than aftermarket alternatives.

Key Features and Benefits of Flywheel MC13 201-02301-6104

Frequently Asked Questions – Flywheel MC13 201-02301-6104

Q1: Is this flywheel a direct replacement for the original SINOTRUK MC13 engine flywheel?

Yes. Part number 201-02301-6104 is manufactured to OEM dimensional and material specifications. It bolts directly onto the MC13 crankshaft flange without any machining or adapter required.

Q2: What is the expected service life of this flywheel under normal operating conditions?

Under standard heavy-duty trucking conditions with proper clutch maintenance, this flywheel is engineered to exceed 500,000 km. However, aggressive driving habits, frequent overloading, or clutch slippage can accelerate wear on the friction surface.

Q3: How do I know when the flywheel needs replacement?

Common indicators include excessive clutch judder during engagement, visible heat spots or cracks on the friction face, abnormal starter motor noise (indicating ring gear wear), and measurable runout exceeding 0.15 mm on the clutch mounting surface.

Q4: Can this flywheel be resurfaced instead of replaced?

Light resurfacing is possible if the friction face shows minor scoring without heat cracks. However, if material removal exceeds 0.5 mm from the original specification, or if heat discoloration penetrates deeply, full replacement is strongly recommended to maintain clutch performance and safety.

Q5: Does the flywheel come with the ring gear pre-installed?

Yes. The flywheel ships as a complete assembly with the hardened ring gear already shrink-fitted to the flywheel body, ready for immediate installation.

Q6: What is the minimum order quantity for bulk procurement?

We accommodate orders from single-piece samples to full container loads. Contact our sales team to discuss volume pricing tiers that match your procurement schedule.
