Overview
The ZF 4642.103.200 OUTPUT for WG150 is a critical driveline component engineered to transfer rotational force from the transmission’s planetary gear set to the output flange. Situated at the rear of the WG150 series housing, this OEM genuine part ensures precise torque delivery and maintains proper alignment within the gear train. The SKU 4642.103.200 is machined from high-strength alloy steel to withstand continuous heavy-load cycles in construction, agricultural, and material handling equipment. When paired with a robust TRANSMISSION HOUSING (4642101108), this output component forms the backbone of the driveline’s structural integrity.
Symptoms of Failure
- Output flange oil leaks: Worn seals around the 4642.103.200 allow transmission fluid to escape, leaving puddles under the vehicle and causing low fluid levels.
- Gear slipping under load: A fatigued output shaft can cause intermittent disengagement from the planetary carrier, resulting in sudden power loss during acceleration or climbing.
- Excessive driveline vibration: Bearing surface wear on this part creates radial play, transmitting harsh vibrations through the driveshaft at highway speeds.
- Metallic grinding noises: Internal spline degradation produces a distinct grinding sound when shifting between forward and reverse gears.

Compatibility
This genuine ZF output is primarily designed for the WG150 series but also fits select variants of the WG180 and WG200 transmissions when used with the correct adapter kit. It is fully compatible with the TRANSMISSION HOUSING (4642301208) found in later WG150 revisions. For proper identification, always verify the TYPE PLATE (0730365125) on your transmission before installation. The output shaft is secured using a GROOVED STUD (0631311009) to prevent axial movement during high-torque operation.
