BS428X22 Transmission Oil Pan ZL20-034001

Product Introduction

This ZL20-034001 BS428X22 transmission oil pan acts as the oil sump for wheel loader transmission assembly. It stores transmission lubrication oil and serves as the bottom sealing housing of the gearbox. It collects lubricating oil, keeps impurities settling at the bottom, and protects internal transmission gears, bearings and clutch components from external dust, mud and impact damage.

The oil pan is fabricated from thickened steel plate with stamping and welding process. The flange edge is precision machined with evenly distributed bolt holes to guarantee uniform compression of the sealing gasket and prevent oil seepage. The exterior is coated with durable yellow anti-corrosion paint, resisting rust, mud splash and abrasion in mining and earthmoving harsh working conditions. The built-in oil outlet interface is precisely positioned for convenient oil draining and maintenance. The reinforced structural design effectively resists deformation from collision and vibration during loader operation.

Manufactured strictly in accordance with OEM dimensional standards, this transmission oil pan can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished oil pan undergoes tightness pressure testing and dimension inspection before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
