2nd gear drive friction disc for ZL40502BS315 transmission 20309000201

Product Introduction

This 20309000201 second gear drive friction disc is a core clutch friction component for the 2BS315 series planetary transmission, widely used on XCMG ZL40 and ZL50 wheel loaders. Installed inside the gearbox’s 2-speed clutch assembly, it controls the power engagement and disengagement of the second gear, transmitting torque and realizing smooth gear shifting during loader operation.

The friction disc adopts high-performance friction material compounded on the metal substrate. The surface is precision grooved, which optimizes oil circulation and heat dissipation during frequent shifting. It maintains stable friction coefficient under continuous heavy load and high temperature, resisting thermal fading and surface glazing. The precisely machined inner mounting holes ensure accurate positioning and even force distribution, avoiding partial wear, slipping or burning of the friction plate under construction site, mining and earthmoving heavy-duty working conditions.

Manufactured strictly in accordance with OEM dimension standards, this friction disc can directly replace the original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every piece undergoes flatness inspection and friction performance testing before delivery. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
