Overview
The ZF 4642.330.224 INTERMEDIATE FLANGE is a precision-engineered OEM genuine component designed for the WG150 series transmission. This critical part serves as the structural bridge between the main transmission housing and the rear output assembly, ensuring correct axial alignment and torque transfer. The SKU 4642.330.224 is machined from high-strength cast iron to withstand the extreme torsional loads common in heavy-duty industrial applications. When installed, it mates directly with the TRANSMISSION HOUSING (4642101109) and the TRANSMISSION HOUSING (4642301205), forming a sealed, rigid interface that prevents misalignment during operation.
Symptoms of Failure
- Oil seepage at the intermediate joint: A worn or cracked 4642.330.224 flange often allows transmission fluid to escape between the housing sections, leaving visible drips under the vehicle or equipment.
- Vibration during gear engagement: When the intermediate flange loses its dimensional integrity, the output shaft can wobble, causing noticeable shuddering or vibration when shifting under load.
- Metal debris in the oil pan: As the flange surface degrades, small metallic particles may break free and circulate through the system, often detected during routine oil analysis.
- Difficulty maintaining gear position: A warped flange can alter the alignment of the shift mechanism, leading to intermittent gear slippage or incomplete engagement.

Compatibility
This intermediate flange is primarily engineered for the ZF WG150 series, but its design also accommodates the WG180 and WG200 transmissions when used with the correct adapter kit. It is not compatible with the WG120 or WG250 series without significant modification. For proper installation, ensure the mating surfaces are clean and use new GROOVED STUD (0631311009) fasteners to achieve the specified torque. The TYPE PLATE (0730365125) should also be replaced if the original is damaged, as it provides critical identification data for the assembly.
