ZF 4657.101.041 TRANSMISSION HOUSING for WG210 | OEM Genuine Part

Overview

The ZF 4657.101.041 TRANSMISSION HOUSING is the central structural core of the WG210 series gearbox. This OEM genuine part encloses the planetary gear sets, valve body, and clutch packs, providing the precise alignment and oil-tight environment required for high-torque industrial applications. As the main casing, it absorbs all operational stresses and thermal expansion. The SKU 4657.101.041 is a direct factory replacement, ensuring exact bolt-hole patterns and sealing surfaces for a reliable rebuild.

Symptoms of Failure

• External oil seepage at mating flanges: A cracked or warped housing allows transmission fluid to escape, often visible as drips near the bell housing or rear seal area.
• Gear engagement hesitation or slipping: Internal distortion of the housing can misalign shafts, causing intermittent power loss under load.
• Unusual metallic whining or grinding: Bearing bore wear within the housing leads to excessive gear lash and audible noise during acceleration.
• Contaminated fluid from cracked casting: Hairline fractures allow debris ingress, accelerating wear on clutches and valves.
