High-Performance Replacement Friction Discs for CASE Construction Equipment: Technical Guide
High-Performance Replacement Friction Discs for CASE Construction Equipment: Technical Guide

CASE construction machinery, from legendary backhoe loaders to powerful dozers, is built for versatility and endurance. The heart of these machines—the transmission and wet brake systems—requires high-quality friction discs to ensure responsive handling and reliable stopping power. For equipment owners and spare parts distributors, finding replacement friction plates that deliver OE-level performance is critical. This guide covers key CASE series: 134, 190, and 243.
CASE OEM Cross-Reference & Technical Specs
Our aftermarket friction components are engineered to provide consistent torque transfer and quiet operation for CASE industrial drivetrains.

|---|---|---|---|---|
| 1341144C1 | 133 * 92 * 2.3 | Internal 38T | Premium Sintered Bronze | CASE 580 Series Backhoe Loaders |
| 190440A1 | 158 * 105 * 2.5 | Internal Teeth | Sintered Bronze | CASE 521 / 621 Wheel Loaders |
| 243026A1 | 178 * 122 * 3.2 | External Teeth | Sintered Bronze | CASE Dozers & Crawler Tractors |
Optimized for Engagement and Wear Resistance
CASE machinery often operates in varying soil conditions, putting constant stress on the clutch packs. Our replacement friction materials are formulated to provide:
- Controlled Coefficient of Friction: Designed to offer a stable μ (0.33 - 0.36) for smooth gear transitions and reduced hydraulic shock.
- High Thermal Capacity: The copper-based sintered material efficiently dissipates energy, preventing surface glazing and core plate distortion.
- Oil Flow Management: Precision-stamped oil grooves ensure a consistent lubricant film, vital for the cooling of CASE wet brake and clutch units.
Quality Assurance Standards
We ensure that our CASE-series parts meet the high expectations of global maintenance professionals:
- Core Plate Hardness: Tempered steel cores resist bending under high clamping forces.
- Dimension Verification: Parallelism is held within 0.05mm to prevent drag during disengagement.
- Spline Integrity: Every 38T or custom internal gear profile is master-gauge tested for a perfect fit on original CASE shafts.
