Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized main clutches within our power train parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and mechanical transmission configurations, ensuring that every component meets rigorous Komatsu standards for power control and preventive maintenance:
• Machine & Heavy-Duty Main Clutch System Compatibility: Engineered for a broad range of Komatsu classic mechanical drive bulldozers, our main clutch solutions ensure exact material strength ratings, dimensional tolerances, and structural interface definitions for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty Main Clutch Range: 1. Main Clutch Assemblies: Designed with high thermal capacity and strong clamping force to withstand continuous high-output diesel engine torque shocks; 2. Driven & Pressure Plates: Formulated to provide strong static friction and resist carbonization and thermal degradation under frequent half-engagement operating conditions; 3. Release Bearings, Levers & Springs: Treated with extreme high-pressure quenching to ensure smooth clutch release and rapid resetting.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu main clutch parts alongside rigorous high-performance aftermarket alternatives featuring reinforced heat-resistant friction formulas, delivering exceptional operational reliability and extended service lifespan at a cost-effective procurement point for global clients.
Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global main clutch component 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 tens of main clutch assemblies and friction plates matching Komatsu mainstream mechanical drive bulldozers. Backed by barcode-enabled intelligent warehousing and Komatsu cross-reference databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replenishment needs for overseas fleet workshops and minimize equipment downtime caused by clutch slip or burning halting complete machine operations.
• Anti-Rust Sealing and Moisture-Proof Packaging: We implement specialized industrial packaging standards for precision friction planar surfaces, spline inner bores, and release bearings of all pressure plates and driven plates utilizing heavy-duty long-lasting anti-rust oils and independent moisture-proof vacuum plastic sealing bags, while high-density anti-collision pearl cotton and wooden separation strips between large pressure plates ensure zero metal oxidation or moisture absorption during transcontinental ocean freight under salt spray and high humidity environments.
• Heavy-Duty Crated Protection: Bulk heavy-duty main clutch assembly and pressure plate shipments are packed in high-strength export fumigated wooden crates with custom anti-vibration timber blocks and high-strength bolts suspending heavy units off the container floor to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without deformation.
• Consolidated Sourcing for Clutch Overhaul Kits: We support overseas clients by consolidating large main clutches alongside matching full sets of high-strength connection bolts, release bearings, crankshaft rear oil seals, and transmission input shaft oil seals into precise bundled main clutch maintenance kits, achieving a one-stop purchasing model that pairs powertrain service supplies while significantly reducing comprehensive logistics costs for overseas workshops.
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 asset health monitoring reliability.
• Application-Specific Clutch Durability Solutions: We address extreme jobsite challenges—such as heavy rock blasting and high-intensity continuous dozing operations—where original driven plates suffer friction material charring, cracking, and torsional spring breakage under frequent half-engagement high-heat conditions. We also provide professional engineering upgrades utilizing high-strength copper-based or semi-metallic high-temperature-resistant friction materials and high-elasticity strong anti-fatigue clamping springs.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like insufficient power during gear engagement, climbing weakness, or the loss of clutch free play accompanied by release bearing screeches. This focuses on two critical protocols: 1. Free Play Inspection & Adjustment: Technicians must regularly inspect and adjust clearances between release levers and release bearings—strictly prohibiting zero free play that causes release bearings to burn out or leads to insufficient clamping force and clutch slippage; 2. Flywheel Face & Runout Inspection: Service technicians must use dial indicators to check engine flywheel runout when replacing new driven plates, strictly prohibiting flywheel distortion from causing uneven loading and rapid wear on new friction plates.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including main clutch alignment disassembly diagrams, pressure plate bolt cross-pre-tightening torque standards, release lever height adjustment specifications, and visual guides, assisting overseas technical personnel in executing standardized construction.
Call to Action & User Experience
