ZF 4657.183.273 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.273 LOOSE PARTS kit is a critical service component engineered specifically for the WG 210 series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure the main housing sections during rebuild or overhaul. The SKU 4657.183.273 sits at the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring precise alignment and leak-free operation under high torque loads. Without this loose parts set, the structural integrity of the entire gear train is compromised.

Symptoms of Failure

• External oil seepage at housing joints: When the 4657.183.273 fasteners lose preload, transmission fluid escapes between the HOUSING REAR PART and main casing, leaving visible drips under the vehicle.
• Intermittent gear engagement noise: Worn or missing loose parts allow micro-movement between housing sections, producing a metallic clatter during acceleration or deceleration.
• Progressive gear slippage under load: As the HOUSING REAR SECTION shifts out of alignment, clutch pack clearance changes, causing delayed or incomplete gear engagement.
• Vibration through the driveline: Loose housing bolts from a degraded 4657.183.273 set create harmonic vibrations that worsen at highway speeds.

Technical Specifications

Compatibility

This genuine ZF 4657.183.273 LOOSE PARTS kit is designed for the WG 210 series transmission family. It is also compatible with WG180, WG200, and WG250 models that share the same housing bolt pattern and sealing geometry. Always verify the production date of your transmission; units manufactured after 2018 may require an updated fastener set. The kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain factory clamping force.
