2BS315 Transmission First-Gear Central Gear ZL40A.30.5-18

Product Introduction

This ZL30D-11-02 rear stopper with 430mm length is a limit component for XCMG LW500F wheel loader transmission assembly. With external spline structure, it is installed inside the gearbox to limit the axial displacement of internal gear sets and sliding components. It keeps gears and friction parts in correct working position during power transmission, prevents excessive axial movement, avoids gear collision and abnormal meshing, and stabilizes gearbox operation.

The stopper shaft is forged from high-grade alloy steel and undergoes carburizing quenching heat treatment. The spline surfaces are precision machined to achieve high hardness, good wear resistance and strong impact resistance. The whole shaft maintains excellent straightness to ensure accurate positioning and reliable limiting effect under repeated heavy-load impact. Spline parameters, total length and outer diameter fully comply with OEM specifications for direct replacement during gearbox overhaul. It addresses common failures including spline wear, shaft bending, positioning failure and abnormal gearbox noise caused by worn original stopper.

Manufactured strictly in accordance with OEM dimensional standards, this ZL30D-11-02 rear stopper can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished stopper undergoes straightness, spline profile and hardness inspection before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
