Product Introduction: A high-density cast iron flywheel with a precision-machined friction surface and integrated ring gear (for starter engagement). It features evenly distributed mounting bolt holes for crankshaft connection, dynamic balance calibration, and a heat-treated surface for wear and high-temperature resistance. Some models are equipped with a ring gear press-fitted structure for easy replacement.

Product Function: Stores the rotational kinetic energy generated by engine combustion strokes to drive the crankshaft during the intake, compression, and exhaust strokes, ensuring smooth and continuous engine operation. The friction surface provides a mating surface for the clutch (in manual transmission systems) to transmit torque to the transmission, and the ring gear cooperates with the starter to realize engine ignition startup.

Your engine’s heartbeat depends on a flywheel that refuses to quit. The Engine Flywheel 5269358 for Cummins ISF2.8 Diesel Engine delivers rock-steady rotational energy storage, smooth clutch engagement, and vibration-free power transmission — exactly the way Cummins engineered it. Sourced through METTLEAD Truck Parts’ factory-direct supply chain, this flywheel meets strict OEM dimensional and metallurgical standards while giving procurement teams the pricing edge they need on bulk orders.

Whether you’re restocking a regional parts warehouse or fulfilling a fleet maintenance contract, this flywheel keeps your Cummins ISF2.8-powered vehicles turning over reliably — shift after shift, mile after mile.

Key Features and Buyer Benefits

Precision-Balanced for the Cummins ISF2.8 Platform

Every Engine Flywheel 5269358 undergoes dynamic balancing to minimize torsional vibration across the full RPM range of the Cummins ISF2.8 diesel engine. This protects crankshaft bearings, extends clutch disc life, and preserves drivetrain integrity over hundreds of thousands of kilometers.

OEM-Matching Material Composition

Cast from high-carbon gray iron (HT250/FC250 equivalent), the flywheel’s friction surface is hardened to 180–230 HB, matching the original Cummins specification for heat dissipation and wear resistance during repeated clutch engagement cycles.

Direct Cost Savings Without Quality Compromise

METTLEAD’s factory-direct model eliminates middlemen. Procurement managers consistently report 30–45% cost reductions compared to sourcing through traditional OEM dealer networks — without sacrificing dimensional accuracy or material grade.

Ready-to-Install Fitment

Bolt pattern, ring gear tooth count, and pilot bearing bore are machined to exact OEM tolerances. Zero modification is required — the flywheel drops directly onto the ISF2.8 crankshaft flange and mates with standard SAE clutch assemblies.

Strict Quality Control at Every Stage

Each flywheel passes through coordinate measuring machine (CMM) inspection, hardness testing, and dynamic balance verification before shipping. Defect rates are held below 0.3% across production batches.

Technical Specifications – Engine Flywheel 5269358

Application Scenarios – Where This Flywheel Works

The Cummins ISF2.8 diesel engine powers a broad family of light-duty commercial vehicles across global markets. The Engine Flywheel 5269358 serves as a direct replacement in the following platforms:

• Foton Aumark / Ollin Series – Light-duty urban delivery trucks widely deployed across Africa, Southeast Asia, and South America.
• Foton Tunland Pickup – Utility pickup trucks used in mining support, agricultural logistics, and rural transport.
• GAZ Gazelle Next (Russia/CIS) – Commercial vans and chassis-cabs running the ISF2.8 for last-mile delivery.
• BAW / BAIC Light Trucks – Municipal and construction-site vehicles requiring frequent clutch engagement under heavy loads.
• Bus & Minibus Platforms – Passenger transport vehicles in emerging markets where the ISF2.8 provides a fuel-efficient, low-emission power unit.

In every scenario, the flywheel absorbs cyclic torque impulses from the ISF2.8’s four-cylinder combustion sequence and delivers consistent rotational inertia to the transmission input shaft — critical for smooth shifting under load.

OEM/ODM Capability – Custom Packaging & White-Label Supply

METTLEAD Truck Parts supports flexible business models beyond standard supply:

• White-Label Packaging – We print your brand logo, part number, and barcode directly on the box. Your customers see your identity, not ours.

• Private Catalog Integration – We supply technical datasheets, high-resolution product images, and fitment data formatted for your ERP or e-commerce system.
• Volume-Tiered Pricing – MOQ starts at just 10 pieces. Deeper discounts activate at 50, 100, and 500-unit tiers — structured to reward growing partnerships.

Every white-label order passes through the same quality control pipeline as our branded inventory. The label changes; the standard does not.

Client Case Study – Engine Flywheel 5269358 in Bulk Fleet Supply

A Nairobi-based fleet parts distributor managing aftermarket supply for 800+ Foton Aumark trucks approached METTLEAD with a recurring problem: inconsistent flywheel quality from multiple suppliers was causing premature clutch failures and costly vehicle downtime.

After switching to METTLEAD’s Engine Flywheel 5269358 for Cummins ISF2.8 Diesel Engine, the distributor reported:

• Zero warranty returns across 3 consecutive quarterly shipments (total: 420 units).
• 22% reduction in clutch-related service calls across their client fleet within 6 months.
• 38% landed-cost savings compared to their previous branded OEM channel.

The partnership expanded to include flywheels, clutch pressure plates, and crankshaft rear oil seals — all sourced through METTLEAD’s Cummins engine parts catalog.

Frequently Asked Questions – Engine Flywheel 5269358

Is this flywheel an exact match for the original Cummins 5269358 part number?

Yes. The Engine Flywheel 5269358 replicates the OEM blueprint — identical bolt circle diameter, ring gear tooth count (129T), pilot bore dimension, and friction surface finish specification (Ra ≤ 1.6 μm). It installs without any machining or adapter modifications on the Cummins ISF2.8 crankshaft.

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

Under standard commercial vehicle duty cycles (urban delivery, mixed highway), the flywheel reliably exceeds 200,000 km before the friction surface requires resurfacing or replacement — consistent with OEM longevity expectations for the ISF2.8 platform.

Can the friction surface be resurfaced (machined) during a clutch replacement?

Absolutely. The gray iron composition and 180–230 HB hardness range allows standard flywheel resurfacing on a lathe. We recommend maintaining a minimum thickness of 25.4 mm after machining to preserve safe rotational mass and heat sink capacity.

Does this flywheel come with the ring gear pre-installed?

Yes. The 129-tooth ring gear is thermally shrink-fitted to the flywheel body during manufacturing. It arrives ready for starter motor engagement — no separate ring gear purchase or press-fitting is needed.

What packaging protection is provided for international shipping?

Each flywheel is individually wrapped in anti-rust VCI film, cushioned with high-density foam, and packed in a reinforced corrugated carton rated for ocean freight stacking. Palletized orders receive additional stretch-wrap and corner protection.

How does METTLEAD verify flywheel balance before shipment?

Every production batch undergoes dynamic balance testing on a dedicated balancing machine. Residual imbalance is held within ≤ 5 g·cm — well within the Cummins ISF2.8 engine’s tolerance window for NVH (noise, vibration, harshness) performance.
