Engine Parts/Turbochargers

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized turbochargers and components within our engine parts catalog to support diverse heavy-duty equipment:
• Machine & Engine Series Compatibility: Engineered for a broad range of Komatsu heavy-duty engines, our parts ensure exact flange dimensions, wheel tolerances, and actuator profiles for a 100% perfect match, lossless alignment, and factory-grade boost performance.
• Complete Turbocharging System Range: 1. Heavy-Duty Turbocharger Assemblies: Units manufactured with high-temperature high-nickel alloy turbine housings and high-strength aluminum compressor wheels to ensure sustained high-efficiency boost pressure under extreme operating conditions; 2. Electronic Variable Geometry Turbochargers (VGT): Perfectly matched to modern electronic control Komatsu engines to deliver precise flow control and low-speed torque bursts across all operating ranges; 3. Turbo Core Cartridges & Repair Kits: Precision dynamically balanced rotating assemblies (CHRA), thrust bearings, journal bearings, and efficient sealing rings to satisfy economical overhaul needs; 4. Intercooler Hoses & Boost Pipes: Reinforced silicone hoses and clamp assemblies capable of withstanding high-pressure and high-temperature airflow impacts.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu turbocharger assemblies alongside rigorous bench-tested aftermarket parts, delivering exceptional reliability and extended service lifespan at a cost-effective price point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global turbocharger procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of hundreds of differing specifications of Komatsu mainstream heavy-duty excavator and bulldozer turbochargers. Backed by barcode-enabled intelligent warehousing and Komatsu parts databases, we guarantee precise matching and immediate dispatch upon order confirmation to minimize jobsite downtime caused by turbocharger bearing seizure and power loss.
• Vacuum Sealing and Crated Packaging: We implement specialized industrial packaging standards for turbochargers featuring internal rotating assemblies operating at rotational speeds exceeding 100,000 RPM with strict balance and cleanliness requirements alongside vulnerable external machined flanges and thin-walled housings, utilizing high-hardness plastic dust plugs to seal inlet, outlet, oil feed, and drain ports, and employing fully sealed vapor corrosion inhibitor anti-rust vacuum plastic wrapping to completely isolate marine humidity and micro-dust, backed by high-density molded foam suspension fixation and specialized fumigated solid wood export heavy-duty crates to ensure components do not suffer rotor shaft bending, housing impact breakage, or rust during transcontinental ocean or air transit.
• Consolidated Sourcing: We support overseas clients by consolidating turbochargers alongside matching engine oil filters, air filters, oil coolers, exhaust manifold gaskets, and overhaul kits into precise bundled shipments, maximizing container space utilization and significantly reducing international freight costs for overseas machine maintenance facilities.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for power unit induction assets.
• Application-Specific Durability Solutions: We address common field issues in extreme jobsite environments, such as dusty open-pit quarries and high-heat desert mines where factory turbochargers suffer compressor wheel destruction from micro-dust ingestion through compromised air filters and bearing seizure caused by oil coking from high heat. We also provide professional engineering upgrades, including wear-resistant fully floating bearings and high-temperature high-nickel alloy turbine sections.
• Troubleshooting and Installation Guidelines: We address common user concerns regarding Komatsu excavator exhaust blue smoke, significant power drops accompanied by high-pitched whining noises, or repeated bearing failure on newly installed turbochargers by providing professional diagnostic and replacement guidance. This includes emphasizing the mandatory execution of a pre-lube and oil feed protocol to thoroughly clean or replace turbocharger oil feed lines, inject clean oil into the oil inlet during installation, and manually rotate the shaft to prevent dry-start bearing scoring, while instructing technicians to thoroughly clean accumulated oil from intercoolers after oil leakage events to prevent runaway engine acceleration caused by oil ingestion into combustion chambers.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering Komatsu turbocharger oil feed and drain bolt torque specifications, exhaust manifold installation sequences, and boost pressure testing standards, assisting overseas technical personnel in maintaining standardized installations.
