ZF 4143.103.036 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.036 OUTPUT is a critical OEM genuine component engineered for the final drive assembly of heavy-duty ZF transmissions. This part serves as the primary output flange or hub, transferring rotational torque from the transmission’s planetary gear set to the driveline. Positioned at the rear of the transmission housing, it interfaces directly with the output shaft and seals the drivetrain against contamination. The SKU 4143.103.036 is precision-machined to OEM tolerances, ensuring a secure fit within the HL 100 Series and HL 270 Series transmission families. When installed alongside the 4143101034: HOUSING and 4143301055: HOUSING, this output component maintains structural integrity under high-load conditions.

Symptoms of Failure

• Oil leakage at the output seal area: A worn 4143.103.036 output flange can cause transmission fluid to weep past the seal, leading to low fluid levels and potential gear damage.
• Vibration or driveline shudder during acceleration: When the output hub develops play, it induces noticeable shaking, especially under load, mimicking a failing universal joint.
• Intermittent gear slipping or loss of power transfer: A cracked or fatigued output component can cause the transmission to momentarily lose engagement, resulting in erratic shifting.
• Metallic debris in the transmission pan: Friction between a failing output flange and the 4143298040: CASE can shed metal particles, contaminating the hydraulic system.

Technical Specifications

Compatibility

This genuine ZF output component is designed for the following transmission models, primarily within the HL series: HL 100, HL 270, WG 180, WG 200, and WG 250. It is also compatible with select Ecomat and Ecolife variants that share the same output flange geometry. Always verify the spline count and bolt pattern against your existing assembly. The 0631329135: SPRING PIN is frequently replaced concurrently to secure the output hub to the shaft.
