Product Introduction: A high-strength cast-iron timing gear with precision-machined teeth and a heat-treated surface for wear resistance. It features a lightweight, ribbed design with a central hub and multiple mounting holes for secure attachment to the camshaft or crankshaft. The gear teeth are precision-ground to ensure accurate meshing and timing synchronization.

Product Function: Transmits rotational motion from the crankshaft to the camshaft, ensuring precise synchronization of the engine’s valve timing and piston movement. This coordination ensures optimal intake and exhaust valve operation, maximizing engine efficiency, power output, and fuel economy. The robust design withstands high torque loads and maintains timing accuracy over long service intervals.

Customer Case Study — Timing Gear 3697562 in Action

In Q1 2024, a fleet management company operating 220+ Cummins ISX-powered trucks across East Africa approached METTLEAD with an urgent procurement challenge. Their existing supplier had delivered inconsistent Engine Timing Gears 3697562 Cummins replacements — resulting in premature gear wear and two costly in-field engine failures within six months.

After receiving METTLEAD sample units for bench testing and dimensional verification, their engineering team confirmed our Engine Timing Gears 3697562 Cummins met or exceeded OEM specifications on every measured parameter — tooth profile tolerance, surface hardness, and runout concentricity. They placed an initial order of 500 units with white-label packaging under their house brand.

Results after 8 months in service:

• Zero timing-gear-related failures across the installed fleet
• 14% reduction in per-unit procurement cost versus their previous supplier
• Lead time shortened from 45 days to 18 days through METTLEAD’s ready-stock program
• Repeat order of 800 units placed for Q4 2024 deployment

This is what happens when precision engineering meets factory-direct efficiency. Your fleet deserves the same reliability.

Frequently Asked Questions — Engine Timing Gears 3697562 Cummins

What engines does the timing gear 3697562 fit?

The Engine Timing Gears 3697562 Cummins is designed for the camshaft gear train in Cummins ISX and X15 series heavy-duty diesel engines. It functions as a direct drop-in replacement for the OEM component without requiring any machining or adaptation.

What material is this Cummins timing gear made from?

It is manufactured from 20CrMnTi alloy steel — carburized, quenched, and tempered to achieve a case hardness of HRC 58–62 and a core hardness of HRC 30–45. This delivers excellent wear resistance on the tooth surface while maintaining impact toughness at the core.

How does this timing gear compare to the original Cummins part?

Our Engine Timing Gears 3697562 Cummins is manufactured to match OEM dimensional tolerances, material specifications, and performance standards. Every batch is inspected for tooth profile accuracy, concentricity, and hardness to ensure it performs identically to the genuine Cummins component in real-world operation.

What causes engine timing gear failure?

Common failure modes include insufficient surface hardness leading to pitting, poor tooth engagement from manufacturing tolerances being out of spec, contaminated lubrication causing abrasive wear, and misalignment during installation. METTLEAD’s strict QC process addresses the first two causes at the production level.

Can I order this timing gear with my own brand packaging?

Yes. METTLEAD offers full white-label and custom packaging services for the Engine Timing Gears 3697562 Cummins — including printed cartons, branded part labels, and customized documentation inserts. Contact our team to discuss your branding requirements.
