Overrunning Clutch (2nd Axle Shaft) 272200270 (5132) 2BS315A(D) for ZL4050 Transmission

Product Introduction

This overrunning clutch assembly (part number 272200270 / 5132, model 2BS315A(D)) is fitted to the 2nd axle shaft of ZL4050 transmission. It acts as a one-way power transfer component inside the gearbox. The overrunning clutch allows torque transmission in one direction while freely rotating in the opposite direction, realizing automatic speed switching during gear shifting and preventing power backflow in the loader’s planetary transmission system.

The assembly integrates large outer gear, inner gear set, needle roller overrunning clutch, ball bearings and fastening bolts. All gear components are forged alloy steel with carburizing and quenching heat treatment, featuring high tooth surface hardness, strong wear resistance and impact resistance. Precision gear grinding ensures low meshing noise and stable load bearing under continuous heavy-duty working conditions. The one-way clutch core is precisely matched to guarantee reliable engagement and disengagement. All mounting holes and spline dimensions strictly follow OEM specifications for direct replacement in ZL4050 transmission.

Manufactured strictly in accordance with OEM dimensional standards, this overrunning clutch assembly can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished assembly undergoes tooth profile inspection and one-way rotation performance testing before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
