ZF 5838.300.024 OIL FEED COVER | OEM Genuine Part

Overview

The ZF 5838.300.024 OIL FEED COVER is a precision-engineered OEM genuine component designed to regulate and direct pressurized lubrication within ZF heavy-duty transmissions. Positioned on the lower valve body or main casing of the transmission, this cover ensures a consistent flow of hydraulic oil to critical rotating assemblies, including the differential and axle bevel gear sets. The SKU 5838.300.024 is machined from high-strength aluminum alloy to withstand constant thermal cycling and high-pressure fluid dynamics. Without this cover, the transmission’s internal lubrication circuit cannot maintain proper oil pressure, leading to accelerated wear on adjacent components such as the 5838022003: REAR AXLE and the 5838109001: DIFFERENTIAL.

Symptoms of Failure

• External oil seepage around the transmission housing: A cracked or warped oil feed cover allows pressurized ATF to escape, leaving visible puddles under the vehicle after shutdown.
• Intermittent gear slipping under load: Insufficient oil delivery to the clutch packs causes delayed engagement or momentary loss of torque during heavy excavation or grading operations.
• Elevated transmission operating temperature: A restricted oil feed cover reduces lubrication flow, causing friction-generated heat to spike above normal thresholds.
• Whining or grinding noise from the differential area: Starvation of the 0750117075: TAPER ROLLER BEARING leads to metallic debris generation and audible distress.

Technical Specifications

Compatibility

This oil feed cover is engineered for ZF WG-series powershift transmissions commonly installed in construction machinery. It is a direct fit for the ZF WG180, WG200, and WG310 models. The part also integrates with the 5838300128: DIFFERENTIAL HOUSING assembly, ensuring proper oil routing to the planetary gear sets. Always verify your transmission serial number before ordering, as minor revisions exist between early and late production units.
