ZF 4657.199.046 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.046 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This OEM genuine assembly contains the necessary loose hardware and small components required to secure and align internal assemblies during a rebuild or major repair. Positioned within the main gearcase, this kit interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure proper torque retention and vibration resistance. The SKU 4657.199.046 is a factory-sealed package that eliminates guesswork when replacing worn fasteners and alignment elements in the WG210 power flow path.

Symptoms of Failure

• Transmission oil seepage at housing joints: When the loose parts in this kit degrade, the seal between the HOUSING REAR PART and the main case can lose clamping force, leading to visible oil weeping around mating surfaces.
• Abnormal gear rattle or whine under load: Worn or missing CYLINDRICAL PIN components within this kit allow micro-movement of internal shafts, producing audible noise during acceleration.
• Intermittent gear engagement hesitation: Loose retaining hardware from this kit can cause shift fork misalignment, resulting in delayed or rough engagement when shifting between forward gears.
• Increased driveline vibration at highway speeds: Degraded fasteners in the 4657.199.046 set reduce structural rigidity, allowing the transmission housing to flex and transmit vibration to the chassis.

Technical Specifications

Compatibility

This genuine ZF 4657.199.046 LOOSE PARTS kit is engineered for the WG 210 series transmission family.
