Caterpillar C4.4 Cylinder Block 225-5462 (Fits Perkins 1104D)

Reinforced Durability: Caterpillar C4.4 Block for Industrial Diesel Engine Parts

The Caterpillar C4.4 Cylinder Block 225-5462 is a fast-moving item in our wholesale catalog, designed to support the versatile range of compact construction equipment. Given the widespread use of the C4.4 ACERT engine in backhoe loaders and small excavators, we maintain a steady supply of these castings to help distributors and fleet managers combat downtime. This block offers a cost-effective, high-quality alternative to OEM replacements, specifically engineered to withstand the rigorous duty cycles of urban construction sites.

This “Reinforced Casting” is developed to solve the most common failure point of the C4.4 and Perkins 1104D series: structural cracking caused by thermal stress. By utilizing high-grade alloyed cast iron and optimizing the cooling jacket geometry, this replacement block provides superior resistance to overheating and distortion. It is the ideal foundation for rebuilding engines in the CAT 416E Backhoe or 320D GC Excavator, ensuring leak-free performance under load.

Technical Specifications for C4.4 / 1104D Block

Technician’s Note: Assembly & Inspection

Thermal Stress Warning: The C4.4 engine runs significantly hotter than older mechanical engines due to emissions standards. When replacing a cracked block, you MUST inspect the cylinder head for warping. Installing a flat head onto this new block with a new Multi-Layer Steel (MLS) gasket is the only way to prevent repeat coolant leaks. Do not reuse old head bolts.

Technical FAQ: Caterpillar C4.4 Cylinder Block

Q1: Is this block compatible with Perkins engines?

Yes, the Caterpillar C4.4 is technically similar to the Perkins 1104D series. This block (225-5462) is often interchangeable with Perkins 1104D-E44T applications. Please verify your casting number or engine serial number with us.

Q2: Does this block fit the Mechanical or Electronic Injection engine?

The part number 225-5462 is typically for the Electronic (Common Rail) C4.4 ACERT engines. Mechanical versions (3054C/1104C) use different blocks. It is critical to confirm if your engine has a high-pressure pump or a mechanical rotary pump.

Q3: Why do C4.4 blocks crack?

These engines operate at high internal temperatures to meet Tier 3/4 emissions. If the cooling system is neglected or the engine is overheated, thermal expansion can cause cracks between the cylinder liner and the valve area. Our reinforced blocks are designed to better handle this stress.
