Genuine HOWO Parts - VG1246020010 High-Tensile Flywheel Bolt for Sinotruk WD615 & D12 Engines

The flywheel bolt might be a small component, but it carries the entire torque load of your HOWO truck's drivetrain. The VG1246020010 bolt is specifically engineered for the flywheel assembly of Sinotruk WD615 and D12 engines.

As a specialized supplier of HOWO parts, we provide these bolts in the original factory standard. They are manufactured from high-tensile alloy steel (12.9 Grade) to handle the intense heat and rotational stress of heavy-duty operation. Using non-genuine or substandard bolts here is a major risk, as a single bolt failure can lead to catastrophic transmission or engine block damage.

Technical Specifications

Why "Genuine" is Non-Negotiable:

1. Thread Precision: The VG1246020010 features rolled threads (not cut), which increases fatigue resistance. This ensures the bolt maintains its pre-load even under constant harmonic vibrations.

2. Torque Consistency: Genuine Sinotruk bolts are designed to be torqued to specific yields. Aftermarket replicas often snap or stretch before reaching the required 280-300 Nm (plus angle) specification.

3. Anti-Corrosion: Each bolt is phosphate-coated to prevent seizing, making future maintenance or clutch replacements much easier.

Mechanic's Tip: Always replace the full set of flywheel bolts (usually 8 or 10 depending on the crankshaft flange) during an engine overhaul. Flywheel bolts are 'stretch bolts' and should never be reused
