The Ruich Value 225-5462 is an OEM-spec replacement cylinder block for the Caterpillar C4.4 4.4L engine. Fully cross-compatible with the Perkins 1104D platform, it features CNC line-bored main saddles to resolve cylinder scoring in CAT 416E backhoes and 320D excavators. Fleet supply and export ready.
In the compact and mid-sized earthmoving sector, the Caterpillar C4.4 4.4L diesel engine provides the essential balance of fuel efficiency and raw hydraulic power. Acting as the heavy-duty foundation of this powertrain is the Caterpillar C4.4 cylinder block (OEM 225-5462). Engineered from high-density gray cast iron, this parent-bore block is heavily utilized in high-cycle construction equipment. For fleet managers seeking a reliable C4.4 engine replacement, our factory-direct casting restores the exact structural rigidity required for relentless 320D excavator cylinder block applications and continuous backhoe loader duty cycles.
Equipment operating in severe-dust and high-heat environments often succumb to premature bottom-end failures. The most devastating of these is parent-bore cylinder scoring caused by dirt ingress or prolonged overheating, which permanently damages the integral cylinder walls. Furthermore, extreme torsional loads can lead to a spun main bearing if the block’s main tunnel loses its alignment. Our replacement blocks neutralize these threats. Every casting is 100% pressure-tested to prevent thermal cracking and features meticulously CNC line-bored block main saddles, guaranteeing perfect crankshaft alignment to prevent future bearing seizures.
Understanding cross-platform architecture is vital for modern engine rebuilders. Because of the joint engineering heritage, this block effectively bridges the gap for the Perkins 1104D block requirements, servicing both CAT construction machinery and Perkins-powered industrial generators. By choosing our wholesale CAT engine blocks, independent workshops bypass prolonged dealer backorders and secure a mathematically exact fit for their heavy equipment engine rebuild programs, ensuring maximum uptime for mixed commercial fleets.

Yes, structurally they are identical. Caterpillar and Perkins share engine architectures in this displacement class. The CAT C4.4 is the Caterpillar-branded version of the Perkins 1100 Series (specifically the 1104D). The 225-5462 bare cylinder block casting drops directly into either application, utilizing the same 105mm bore diameter and accessory mounting points.
Diagnosis: The C4.4 is typically a “parent bore” engine, meaning the pistons ride directly on the cast iron block without replaceable wet liners. If you experience severe parent-bore cylinder scoring from dirt ingestion or overheating, the block must be bored to an oversize spec. Solution: If the scoring is too deep to safely bore oversize without compromising cylinder wall thickness, replacing the bare block with our new 225-5462 casting is the safest, most durable repair method.
Diagnosis: A spun main bearing usually occurs due to a catastrophic loss of oil pressure or when the block’s main bearing tunnel becomes warped from extreme overheating or heavy lugging. When the tunnel is no longer perfectly straight, the crankshaft binds, tearing the bearing shell from its seat. Solution: Our replacement blocks are CNC line-bored at the factory with the main caps installed. This guarantees absolute straightness in the main tunnel, providing the correct crush on new bearing shells.
