Drivetrain/Friction Materials

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized friction materials and transmission rebuild components to support diverse heavy-duty equipment (e.g., CAT 950/966/980 loaders, D6/D8/D9 dozers, and 770/777 mining trucks):
• Machine & System Compatibility: Engineered for a broad range of Caterpillar equipment series—covering transmission clutch packs, wet brake assemblies, and steering/final drive clutches—our parts ensure exact inner/outer tooth profiles, tooth counts, widths, thicknesses, and outer diameter dimensions to guarantee a 100% perfect match.
• Complete Friction Materials & Component Integration: 1. Paper & Sintered Bronze Friction Discs: High-load paper-based discs featuring smooth engagement and high thermal capacity, alongside sintered metallic bronze discs engineered for extreme loads and frequent high-torque engagement; 2. Matched Steel Mating Plates: Counterplates manufactured from high-grade alloy steel with precision surface grinding and heat treatment to guarantee zero warpage and uniform clamping pressure; 3. Complete Transmission & Brake Rebuild Kits: Comprehensive overhaul kits packaging friction discs, steel plates, seal rings, O-rings, and springs to satisfy total overhaul requirements.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Caterpillar friction components alongside rigorously tested heavy-duty aftermarket options verified through severe mining bench testing, delivering exceptional friction coefficients and extended wear life at a cost-effective price point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global machinery precision functional component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Massive Inventory and Part Cross-Reference: We maintain large-volume stock of thousands of differing specifications of CAT mainstream transmission and brake friction discs and steel counterplates. Backed by barcode-enabled intelligent warehousing and heavy machinery parts databases, we guarantee precise matching and direct dispatch upon order confirmation to minimize equipment downtime caused by clutch slippage and brake failure stoppages.
• Moisture-Proof and Flat Anti-Stress Packaging: We implement specialized industrial packaging standards for paper-based friction discs vulnerable to moisture absorption, warping, and stacking pressure deformation, utilizing independent vacuum moisture-proof plastic sealing, shock-absorbing blister trays, thickened rigid cartons, and oil-proof inner linings to ensure parts do not suffer moisture absorption, distortion, or edge bruising during transcontinental ocean or air transit.
• Consolidated Sourcing: We support overseas clients by consolidating precision friction disc repair kits alongside matching transmission overhaul parts, drive axle assemblies, or hydraulic pumps into precise bundled shipments, maximizing container space utilization and significantly reducing international freight costs.

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.
• Application-Specific Durability Solutions: We address common field issues in extreme working environments, such as high-intensity continuous loading, open-pit mining frequent sharp turns, and heavy-duty braking, where original paper-based friction discs carbonize and peel rapidly under high temperatures and high pressures, and brake discs experience thermal ablation and seizure. We also provide professional engineering upgrades including high-temperature high-energy sintered bronze friction discs and high-thermal-conductivity composite mating steel plate combinations.
• Troubleshooting and Maintenance Guidelines: We address common user concerns regarding transmission slippage and brake failure by providing professional diagnostic and replacement guidance. This includes comprehensive failure diagnostics helping technicians determine whether faults stem from normal friction disc wear, insufficient system oil pressure from seal leaks, or thermal ablation caused by inferior transmission oil failing to meet Caterpillar TO-4 specifications, alongside emphasis on deep flushing of entire transmission and brake hydraulic circuits and coolers to remove residual carbon deposits and metal fragments and prevent secondary contamination and burnout of new parts.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering Caterpillar clutch clearance measurement standards, friction disc pre-lubrication soaking guidelines requiring complete immersion in clean Caterpillar TO-4 specialized oil prior to installation, and alternating steel counterplate stacking sequence guides, preventing dry friction burnout caused by improper installation.
