Replacement Friction Discs for Adams Motor Graders: Technical Specs for OEM 402303, 402304 & 402430

Update time : 2026-03-09 08:42:20

In heavy-duty road construction, the reliability of a motor grader's transmission is paramount. Selecting the right replacement friction disc for Adams equipment is not just about matching dimensions; it is about ensuring thermal stability and torque consistency. This guide provides a detailed technical breakdown of the most common OEM parts: 402303, 402304, and 402430.

OEM Cross-Reference & Specifications

Precision-engineered aftermarket solutions designed to meet or exceed original performance standards.

OEM Part Number	Dimensions (mm)	Material Type	Primary Application
402303	352 * 203.2 * 4.8	Sintered Bronze	Adams Motor Grader Transmissions
402304	301.5 * 174.6 * 4.0	Sintered Bronze	Clutch Control Units
402430	381 * 203.2 * 4.8	Sintered Bronze	Main Drive Systems

Advanced Friction Material Technology

The 402xxx series for Adams graders requires superior heat dissipation. Our aftermarket components utilize Sintered Bronze (MCFK SI), which offers unique advantages:

Thermal Stability: Maintains a consistent friction coefficient (μ ≈ 0.35) up to 350°C.
Wear Resistance: High-density copper matrix extends service life in high-torque environments.
Shear Strength: Reinforced teeth structure to prevent mechanical failure during intense grading.

Our Quality Assurance Protocols

To ensure 100% fitment and performance, every batch undergoes strict QC:

CNC Machining: Thickness tolerances are maintained within ±0.05mm.
Hardness Verification: Rockwell hardness testing (HRB) for structural integrity.
Surface Finish: Precision grinding for optimal mating plate engagement.

Disclaimer: All manufacturer's names, OEM part numbers, and descriptions are used for cross-reference only. Our products are high-quality aftermarket replacement parts.

A technical analysis of high-performance replacement friction discs for Adams graders. This guide covers the dimensions, material standards, and application fitment for OEM part numbers 402303, 402304, and 402430, ensuring reliable transmission and braking performance in heavy-duty environments.

What performance tests are required for wet clutch friction plates?

Dec 16,2025

Wet clutch friction discs are critical for transmission performance and durability. This guide details essential performance tests—friction coefficient analysis (μ-v, μ-p, μ-T), durability & wear life simulation, thermal fade/recovery, mechanical strength, and lubricant compatibility—conducted per SAE/JIS/OEM standards. Ensure your clutch components meet rigorous quality benchmarks for smooth shifting and long-term reliability in demanding applications.

What consequences may arise from the deterioration of friction plates within a bulldozer's transmission?

Dec 15,2025

Friction plates are critical to a bulldozer’s transmission, controlling speed and power output. Damaged or worn plates lead to unstable operation, accelerated wear of gears and bearings, increased downtime, and higher long-term costs. This article explains why timely replacement is essential for safety, performance, and extending your equipment’s lifespan.

A Casual Discussion on Brake Pad Friction Materials

Dec 12,2025

A vehicle's braking system is as critical as its engine—your ultimate safety relies on the friction material within your brake pads. This article explores the science behind friction materials, explaining how complex formulations—comprising grinding fillers (e.g., zirconium silicate), wear reducers (graphite), and functional fillers—work together to balance performance factors like friction coefficient, noise, wear, and heat resistance. We break down common formulations (semi-metallic, ceramic, low-metallic, hybrid) and their ideal applications, debunking myths like judging quality by magnet attraction. True performance depends on R&D expertise and tailored formulations, not just material presence.
