612600020416 Flywheel For Truck

The 612600020416 Truck Flywheel is a core power transmission part for heavy-duty trucks, mainly matching diesel engines like WD615, WP10 series. It stores rotational inertia, stabilizes crankshaft speed, and drives clutch, starter, and other auxiliary components to work. This ensures the engine runs smoothly during startup, acceleration, or load changes-super important for vehicle power stability and driving reliability. We use good materials and precise manufacturing to make it: the flywheel body is high-strength ductile iron (QT500-7, wear-resistant and impact-proof). The friction surface is quenched (hardness HRC 45-55, anti-slip and wear-resistant). The keyway is precision broached (fits crankshaft shaft head, no loosening). The installation holes, bolt specs, and outer diameter fit the original engine system exactly, so it installs with no mods. It handles tough conditions-180℃ engine heat, 5-500Hz vibration, and oil/grease erosion-without deformation, friction surface wear, or keyway damage. Swapping it is easy: no need to adjust engine position or transmission connection, just disconnect the clutch, remove the bolts, install the new flywheel, fasten the bolts, and test engine operation. Before shipping, we test 'em strict: dynamic balance test (unbalance ≤5g·cm), hardness test (friction surface HRC ≥45), and durability test-so it's reliable.

Product Model: 612600020416

Applicable vehicles: Heavy-duty trucks with WD615/WP10 diesel engines (Sinotruk, Shacman, Foton Auman)

Type: Truck flywheel (ductile iron body + quenched friction surface)

Function: Store rotational inertia, stabilize crankshaft speed, ensure power transmission stability

Material: Flywheel body (QT500-7 ductile iron); friction surface (quenched); keyway (precision broaching)

Installation: Direct replacement-fits original engine interface and bolt specs

Working conditions: -30℃~180℃; max bearing torque ≥800N·m; ≥600,000 km life

① Strong torque bearing capacity: High-strength ductile iron body + optimized structure provide sufficient load-bearing capacity, stabilizing crankshaft rotation. Power transmission efficiency 25% higher than ordinary flywheels.

② Stable operation: Precision dynamic balance treatment reduces vibration, ensuring engine runs smoothly with no jitter (rotation error ≤0.05mm).

③ Perfect for matching models: Made to original engine design-installation holes, bolt spacing, outer diameter match. No adapters or position adjustment needed-saves 35% maintenance time vs universal flywheels.

④ Durable & reliable: Quenched friction surface resists wear, high-strength ductile iron resists deformation. Works stably in extreme temps and high loads-lasts 600k+ km.

This Flywheel (Model: 612600020416) is only for heavy-duty trucks with WD615/WP10 series diesel engines, suitable for Sinotruk, Shacman, Foton Auman. It won't work on gasoline engine trucks or non-matching diesel engines (CA6DL, ISDe series). Those have different crankshaft structures, interfaces, or torque needs-this flywheel won't fit or work.

Q1: Works on gasoline engine trucks?

A1: No-gasoline engines have different structures/torque characteristics. It causes mismatched installation or power failure, leading to engine damage. Get the flywheel for gasoline engines instead.

Q2: Engine jitters after new flywheel install?

A2: First check bolt tightness. If good, check keyway fit with crankshaft. If fit, check dynamic balance. Still jittery? Replace the flywheel (rare defect).

Q3: How to maintain the flywheel?

A3: 1. Check bolts for looseness every 50k km (retighten if needed); 2. Clean friction surface often to remove oil/debris; 3. Inspect friction surface for wear/cracks-replace if wear exceeds 0.5mm.

Q4: Need to replace clutch plate with new flywheel?

A4: Not mandatory but recommended. New flywheel works best with well-maintained clutch plate-old ones affect power transmission. Inspect clutch plate and replace if worn.
