FAQs – Caterpillar C15 Ultra Performance Loaded Cylinder Head (1835296)
1. What makes this “Ultra Performance” cylinder head different from standard replacements?
The Ultra Performance cylinder head features all Inconel valves (both intake and exhaust), a .011 (11 thousandths) fire ring for superior cylinder sealing under high-pressure situations, and higher nickel content casting for enhanced heat dissipation. This combination is specifically designed to handle high-boost applications and extreme operating conditions.
2. What is the fire ring feature and why is it important?
The .011 fire ring is a specialized sealing feature that provides superior cylinder sealing under high-pressure and high-boost conditions. This enhanced sealing capability helps prevent combustion gas leakage, maintains compression, and allows the engine to handle increased power output and boost pressure more reliably.
3. Which Caterpillar engines is this Ultra Performance head compatible with?
This Ultra Performance loaded cylinder head (Part Numbers: 1835296, 20R2645) is designed for Caterpillar 3406E, C15, and C15 Acert diesel engines. It’s engineered as a direct replacement that provides a perfect fit for easy installation across all these engine models.
4. How do all-Inconel valves benefit high-performance applications?
All-Inconel valves (both intake and exhaust) are made from superalloy material that’s many times stronger than steel. This provides exceptional resistance to high temperatures, extreme pressure, and corrosion – making them ideal for high-boost, high-performance applications where standard valves might fail under stress.
5. Is this cylinder head suitable for modified or high-performance engines?
Yes, this Ultra Performance head is specifically engineered for demanding applications. The fire ring design, all-Inconel valves, and enhanced cooling capabilities make it an excellent choice for modified engines, high-boost applications, or any situation where you need superior performance and reliability under extreme conditions.
