ZF 4108.015.050 P 5300 | OEM Genuine Part

Overview

The ZF 4108.015.050 P 5300 is a precision-engineered OEM genuine component designed for the high-stress environment of construction machinery transmissions. This part functions as a critical sealing and alignment element within the main gear housing assembly, ensuring that hydraulic pressure and lubrication channels remain isolated. The SKU 4108.015.050 is specifically machined to interface with the pump drive housing, preventing cross-contamination between the transmission sump and the torque converter circuit. When installed correctly, it maintains the structural integrity of the transmission case, directly supporting the 4108101066 HOUSING and the 4108201298 HOUSING to form a leak-proof assembly.

Symptoms of Failure

• External oil seepage at the pump housing interface: A worn 4108.015.050 component often results in visible hydraulic fluid weeping around the joint between the transmission and the pump drive, particularly during cold starts or high-load operation.
• Erratic gear engagement under load: When this part degrades, internal pressure loss can cause delayed or harsh shifting in forward and reverse gears, especially in WG180 and WG200 series transmissions operating in excavators or wheel loaders.
• Contaminated transmission fluid: Failure of this sealing element allows debris from the torque converter housing to enter the main sump, leading to accelerated wear of the 4108301475 INPUT SHAFT and 0750116277 BALL BEARING.
• Audible whining or cavitation noise: A compromised seal can introduce air into the hydraulic circuit, producing a high-pitched whine from the pump area during operation.

Technical Specifications

Compatibility

This genuine ZF part is primarily designed for use in the WG180 and WG200 series powershift transmissions, commonly found in heavy construction machinery such as articulated dump trucks, graders, and crawler dozers. It also fits select WG150 and WG210 variants where the pump drive housing configuration matches the P 5300 interface. For proper installation, always verify the condition of the 0501215601 OIL LEVEL GAGE and replace the 0501325471 SEALING RING simultaneously to ensure a complete seal renewal.
