The Ruich Value 219-5843 is an OEM-spec aftermarket cylinder head for the Caterpillar C7 7.2L ACERT engine. Featuring an 18-valve OHV design and reinforced injector sleeve bores, it provides a direct-fit solution for Freightliner M2, Ford F-650, and CAT 324D excavators. Bulk pricing available from warehouse stock.
The Caterpillar C7 7.2L engine is a pillar of the medium-duty truck and construction industries, powering everything from Ford F-750 utility fleets to high-cycle mining excavators. At the heart of this ACERT platform, the Caterpillar C7 cylinder head (OEM 219-5843) manages the critical air induction and fuel injection sequences. Ruich Value supplies this precision-engineered top-end assembly to uphold Caterpillar’s rigid QDR (Quality, Durability, and Reliability) standards. Manufactured from high-density gray cast iron, our cylinder heads restore factory-spec 16.2:1 compression and thermal stability required for both heavy-duty earthmoving and on-highway logistics.
Modern C7 engines frequently encounter severe thermal failures, most notably injector sleeve failure and microscopic cracking between valve seats. These issues lead to coolant-fuel mixing and a sudden loss of combustion pressure, resulting in persistent overheating. Our replacement 219-5843 heads are specifically designed to address these failure modes. We utilize an 18-valve configuration (3 per cylinder) with improved coolant passages and high-grade valve seat inserts to resist the extreme exhaust gas temperatures (EGTs) characteristic of HEUI and Common Rail injection cycles.
Engine rebuilders and commercial workshops operating in the global heavy equipment parts network demand uncompromised dimensional accuracy. Every 219-5843 assembly, which cross-references to 236-4739 and 10R-8884, is 100% water jacket pressure tested and vacuum checked before dispatch. Whether you are maintaining a CAT 324D excavator or performing a high-standard overhaul for a Freightliner M2, our factory-direct inventory ensures your 7.2L engine achieves its maximum operational life. We support bulk orders for large-scale fleet maintenance and municipal service programs.

The C7 uses brass injector sleeves to isolate fuel and coolant. Constant thermal expansion and high-pressure vibration can cause the sleeve’s O-rings to fail or the brass itself to erode. This results in fuel entering the cooling system. Our new 219-5843 cylinder heads are machined with optimized sleeve seats to provide a superior mechanical seal compared to aging original castings.
There is significant confusion here: the Caterpillar C7 is a 3-valve per cylinder engine, totaling 18 valves (2 Intake, 1 Exhaust). It is not a 24-valve engine. Using an incorrectly specified head will lead to immediate timing and breathing failure. The 219-5843 is the correct 18-valve architecture. Always confirm your valve count by checking the rocker arm arrangement before ordering.
To ensure a perfect seal and prevent head gasket failure, the bolts must be tightened in a specific sequence. For the C7 ACERT, the standard procedure is an initial torque of 160 Nm (118 ft·lb), followed by a 90-degree turn, and another 90-degree turn. You must use brand-new bolts every time, as they are Torque-to-Yield (TTY) fasteners and stretch permanently during installation.
