Specification

Description

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.
