Caterpillar C18 Crankshaft 222-3236 for CAT 988H & Marine Power

Extreme Duty Power: Forged Caterpillar C18 Crankshafts for Mining & Marine

Industrial Diesel Engine Components reach their zenith in the Caterpillar C18, an 18-liter powerhouse driving the world’s largest wheel loaders and marine vessels. Ruich Value is your premier source for high-performance internal components designed to match the immense torque and continuous-duty requirements of this heavy-industrial engine.

This forged steel crankshaft, referencing OEM 222-3236, is engineered for the Caterpillar C18 ACERT engine. To cope with outputs often exceeding 800HP and extreme marine duty cycles, our crankshafts are manufactured from premium micro-alloyed steel with deep fillet hardening. This ensures exceptional resistance to the high-amplitude torsional vibrations characteristic of long-stroke engines. Whether you are powering a remote genset or a 988H wheel loader in a quarry, our C18 crankshaft restores the uncompromising reliability expected from Caterpillar’s top-tier machinery.

Technical Specifications for CAT C18 ACERT Forged Crankshaft

Technician’s Note: Installation & Inspection

Technician’s Note: The C18’s massive displacement creates significant torsional vibration. When installing a new 222-3236 crankshaft, it is absolutely critical to inspect or replace the viscous vibration damper. A failed damper is the primary cause of snapped crankshafts in C18 marine and genset applications due to unchecked harmonic resonance.

Verified CAT C18 Engine & Equipment Applications

Why Source Heavy Duty Parts From Ruich Value?

• Forged for Mining: We exclusively supply forged steel crankshafts for the C18 to handle the shock loads of mining excavation and continuous marine thrust. Cast iron is strictly prohibited for this application.
• Marine Grade Precision: Our journals are finished to marine-grade tolerances to ensure hydrodynamic stability even under pitch and roll conditions.
• Stroker Validation: We verify the specific stroke length (183mm vs 171mm for C15) to ensure you receive the correct C18 part, avoiding costly displacement mix-ups.
• Heavy Logistics: Packaged in reinforced, moisture-resistant crates to withstand ocean freight and long-term storage in humid environments.

Technical FAQ: Caterpillar C18 Crankshaft

Q: Can I use a C15 crankshaft in a C18 engine?

A: No. Although the C15 and C18 share the same cylinder block bore, the C18 achieves its larger 18.1L displacement through a longer crankshaft stroke (183mm) compared to the C15 (171mm). The crankshafts are physically different and not interchangeable.

Q: Does this crankshaft support Marine Classification Society standards?

A: Our aftermarket C18 crankshafts are manufactured to meet or exceed OEM dimensional and material specifications suitable for marine use. However, for vessels requiring specific class certification (like ABS or Lloyd’s), please consult our technical team regarding available documentation.

Q: Is this crankshaft suitable for repowering older 3406E engines to C18 specs?

A: Converting an older 3406 or C15 block to C18 specs (“stroking it”) requires extensive modifications including pistons, rods, and clearance machining. While the 222-3236 crankshaft is the core component for this, it is a complex custom build recommended only for expert engine builders.
