Caterpillar C15 Crankshaft 221-9360 for CAT 385C Excavator & Peterbilt 379

King of the Road Durability: Forged Caterpillar C15 Crankshafts for Heavy Haul

Industrial Diesel Engine Components are tested to their limits in the Caterpillar C15, the legendary powerplant that drives both massive mining excavators and long-haul trucks. Ruich Value is your premier source for high-performance internal components designed to match the immense torque and horsepower of the “Big Cat” engine family.

This forged steel crankshaft, referencing OEM 221-9360, is engineered for the 15.2L Caterpillar C15 engine (including 6NZ and ACERT models). To cope with outputs exceeding 600HP and 2,000 lb-ft of torque, our crankshafts are manufactured from premium steel alloys with deep fillet hardening. This ensures exceptional resistance to torsional fatigue and bending stress, whether you are hauling heavy loads up a mountain grade in a Peterbilt or pushing overburden in a D8T dozer. Restore the heartbeat of your heavy equipment with a crankshaft built for extreme duty.

Technical Specifications for CAT C15 Forged Crankshaft

Technician’s Note: Installation & Inspection

Technician’s Note: The leading cause of broken crankshafts in C15 engines is a failed torsional vibration damper. When installing a new 221-9360 crankshaft, it is mandatory to replace the vibration damper (harmonic balancer). A worn damper cannot absorb the twisting forces of the 15-liter engine, leading to rapid fatigue failure of the new crankshaft nose or webs.

Verified CAT C15 Engine & Equipment Applications

Why Source Heavy Duty Parts From Ruich Value?

• Forged for Power: We exclusively supply forged steel crankshafts for the C15 to handle the massive firing pressures of this 15-liter engine. Cast iron alternatives are simply unsafe for this application.
• Dual-Market Validation: Our C15 crankshafts are proven in both off-highway mining (yellow iron) and on-highway heavy haulage, covering your mixed fleet needs.
• Precise Balancing: Each unit is dynamically balanced to minimize vibration at high RPMs, protecting your main bearings and block.
• Secure Packaging: Given the size and weight of the C15 crank, we use reinforced steel-banded crates to ensure safe global delivery.

Technical FAQ: Caterpillar C15 Crankshaft

Q: Is this C15 crankshaft interchangeable with the 3406E?

A: In many cases, yes. The C15 block architecture is based on the 3406E. The Ruich Value replacement for 221-9360 is widely compatible with late model 3406E (1MM, 2WS) and early C15 (6NZ) engines. However, always confirm your piston skirt clearance and nose gear configuration with our team.

Q: Does this crankshaft work for Twin Turbo C15 ACERT engines?

A: Yes, the forged steel construction is designed to handle the higher cylinder pressures of the ACERT twin-turbo system found in machines like the D8T and 385C. It meets the strength requirements for these high-stress applications.

Q: What bearing sizes are available for this crankshaft?

A: We supply this crankshaft with Standard (STD) journal dimensions. If you are rebuilding an engine, we can also supply matching tri-metal bearing kits (Main, Rod, and Thrust bearings) in Standard or Oversize configurations upon request.
