ZF 4143.103.035 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.035 OUTPUT is a precision-engineered OEM genuine component designed for the output section of ZF HL 100 and HL 270 series transmissions. This part serves as the critical interface between the transmission housing and the driveline, ensuring torque is transferred efficiently from the gear set to the output flange. As a factory-specified replacement, the SKU 4143.103.035 guarantees exact fitment and durability under high-load conditions. It integrates directly with the 4143101031: HOUSING and the 4143298040: CASE to form a sealed assembly that withstands extreme operational stresses.

Symptoms of Failure

• Output shaft oil leaks – Worn seals around the 4143.103.035 often cause transmission fluid to weep from the rear housing, leading to low fluid levels and potential overheating.
• Gear slipping under load – A degraded output component can result in intermittent power loss or hesitation during acceleration, especially in heavy-duty applications.
• Unusual vibration or noise – Excessive play in the output section produces a distinct humming or grinding sound from the transmission tunnel, indicating bearing or spline wear.
• Driveline backlash – If the output part is compromised, you may notice a clunk when shifting between forward and reverse, signaling misalignment with the 0631329135: SPRING PIN assembly.

Technical Specifications

Compatibility

This OEM genuine output part is primarily compatible with ZF HL 100 and HL 270 series transmissions, which are widely used in agricultural tractors, construction loaders, and industrial material handlers. It also fits select models in the WG180 and WG200 families, where the output shaft configuration matches the 24-spline internal design. For precise fitment, always cross-reference the 4143301055: HOUSING and the 4143301045: SCREEN SHEET to ensure the assembly aligns with your specific transmission variant.
