ZF 4657.183.063 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.063 LOOSE PARTS kit is a critical service package designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential loose hardware and small components required to secure and align internal transmission 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 clamping force and alignment of the planetary gear sets. The SKU 4657.183.063 is a factory-sealed package that eliminates guesswork during overhaul, providing every fastener and spacer needed for the WG210 core assembly.

Symptoms of Failure

• Transmission housing oil seepage at mating flanges: When the loose parts kit components wear or corrode, the seal between the HOUSING REAR PART and the main case can degrade, causing slow oil weeping that leaves residue on the bell housing.
• Audible rattling or vibration during gear engagement: Worn CYLINDRICAL PIN components within this kit can allow slight movement of the valve body or clutch pack, producing a metallic chatter under load.
• Intermittent gear slippage under heavy torque: Loose or missing fasteners from the kit can cause the clutch housing to shift out of alignment, leading to pressure loss and delayed engagement in forward gears.
• Difficulty shifting into reverse or low gear: Degraded locating pins and washers in the 4657.183.063 set can misalign the shift rail, creating a hard shift condition that worsens as the transmission heats up.
