Description
This product is a CAT C4.4 engine long block assembly, specially designed for ionExcavator construction machinery & excavators. As a core replacement power assembly for excavators, it fully integrates cylinder block, cylinder head, crankshaft, piston & connecting rod, valve assembly, timing gear chamber and other complete internal core components. It is a pre-assembled semi-finished product, which can be directly installed in situ to match original CAT excavators and construction machinery without additional assembly of spare parts, and is suitable for heavy-duty construction conditions including engineering construction, mining operation and earthwork construction.
Advantage
OEM-level precise matching: Fully compliant with the original structural dimensions, mounting holes, oil & gas circuit interfaces of CAT C4.4 engine, 1:1 adapted to original vehicle pipelines and circuits, realizing non-destructive in-situ installation without modification or polishing.
Fully pre-assembled structure: Completed cylinder block & head assembly, valve grinding & adjustment, crankshaft & piston assembly, timing system calibration before delivery. Ready for direct installation after arrival, greatly reducing maintenance downtime.
High-strength durable material: The cylinder block and head are made of high-strength wear-resistant alloy cast iron. Internal moving parts are processed with precision heat treatment, featuring high pressure resistance, wear resistance and high-temperature fatigue resistance, perfectly adapting to harsh heavy-duty construction site conditions.
Strict factory inspection: Each assembly undergoes air tightness test, oil pressure test and valve sealing test before delivery, eliminating oil leakage and air leakage risks, with excellent stability after installation.
Cost-effective replacement solution: Equipped with the same installation performance and service life as brand-new original complete engine, while with much lower procurement cost. It is the best cost-effective choice for excavator overhaul and engine replacement.
Performance
Applicable model: CAT C4.4 diesel engine for construction machinery & excavators
Structure form: In-line 4-cylinder, water-cooled direct injection diesel engine long block semi-assembly
Power matching: Fully consistent with original rated power and torque output curve; power response and fuel consumption performance after installation are identical to original factory engine
Durability performance: Vulnerable parts including bearing bushes, pistons and valves adopt high wear-resistant technology, with heavy-load fatigue resistance and excellent stability for continuous construction site operation
Application scenarios: Engine overhaul, replacement and renovation of excavators, loaders, pavement machinery and other construction equipment
