ZF 4657.199.013 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.013 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 Series transmission. This genuine OEM part consolidates essential small components—including seals, retainers, and positioning elements—that are necessary for maintaining the structural integrity of the transmission’s internal assembly. Located within the main gear train housing, this kit ensures that all loose hardware remains secured under high-torque conditions. The SKU 4657.199.013 is frequently ordered alongside the 4657101033: TRANSMISSION HOUSING and the 4657201027: HOUS.FRONT SECT to complete a full overhaul of the WG210 unit.

Symptoms of Failure

• Oil leaks around the front housing interface: When the loose parts kit degrades, seals fail, causing transmission fluid to weep from the joint between the 4657201012: HOUSING REAR PART and the main casing.
• Intermittent gear slippage under load: Worn retaining pins or clips within the kit allow shafts to shift slightly, leading to erratic engagement in higher gears.
• Metallic rattling from the bell housing area: Loose fasteners or missing spacers create a distinct chatter during idle, often misdiagnosed as bearing noise.
• Difficulty engaging reverse gear: A compromised 0631306792: CYLINDRICAL PIN within the kit prevents proper alignment of the reverse idler gear.

Technical Specifications

Compatibility

This genuine loose parts kit is engineered primarily for the WG 210 Series transmission, but it also fits the WG180 and WG200 models due to shared housing architecture. It is compatible with both early and late production runs of the WG210, provided the 4657101033: TRANSMISSION HOUSING and 4657201027: HOUS.FRONT SECT are original ZF units. Always verify the 0631306792: CYLINDRICAL PIN is included in your kit before installation.
