Overview
The ZF 4108.015.017 P 5300 is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This part functions as a critical internal support element within the planetary gear set, ensuring correct axial alignment and load distribution during high-torque operations. As an integral piece of the ZF drivetrain assembly, it directly interfaces with the INPUT SHAFT to maintain gear mesh integrity. The SKU 4108.015.017 is manufactured to original factory tolerances, guaranteeing a direct fit without modification. When installed alongside the HOUSING, this part prevents unwanted axial movement that can lead to premature wear across the entire transmission system.
Symptoms of Failure
- Transmission gear slipping under load: When the 4108.015.017 wears, the planetary carrier loses its precise positioning, causing intermittent gear disengagement during excavation or lifting operations.
- Metallic grinding noise from the transmission housing: A worn part allows metal-on-metal contact between rotating assemblies, producing a distinct grinding sound that intensifies with engine RPM.
- Oil contamination with metallic particles: As the component degrades, fine steel shavings enter the hydraulic circuit, often visible during oil changes or filter inspections.
- Vibration through the chassis during gear shifts: Excessive clearance in this part creates driveline shudder, particularly when transitioning between forward and reverse gears in loaders or dozers.

Compatibility
This genuine ZF part is engineered for use in the following transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG240 series. It is also compatible with certain iterations of the Ecomat 4 and Ecomat 5 transmissions used in wheel loaders, graders, and dump trucks. Always verify the existing HOUSING part number before installation to ensure correct fitment. For transmissions requiring a new GASKET, we recommend replacing it simultaneously to prevent fluid seepage.
