ZF 4642.199.797 LOOSE PARTS for WG200 | OEM Genuine Part

Overview

The ZF 4642.199.797 LOOSE PARTS component is a critical service item designed specifically for the WG 200 series transmission. This OEM genuine part functions as a precision-engineered internal assembly element, ensuring proper torque transfer and hydraulic sealing within the gearbox. Positioned within the main valve body or clutch pack region, the SKU 4642.199.797 replaces worn or damaged loose hardware that can compromise shift quality. When paired with a robust TRANSMISSION HOUSING (4644101249) or a TRANSMISSION HOUSING (4644301402), this part restores factory-spec clearances and prevents premature wear on adjacent components.

Symptoms of Failure

• Erratic shifting or gear slipping under load: Worn loose parts cause inconsistent clutch engagement, leading to delayed or harsh shifts during acceleration.
• Internal rattling or metallic noise: Degraded hardware creates excessive play, producing audible knocking sounds from the transmission housing.
• Hydraulic fluid contamination: Fragments from failing loose parts circulate through the system, clogging filters and damaging seals.
• Oil seepage around the valve body: Compromised fitment allows transmission fluid to escape past gaskets, often requiring a new O-RING (0634306323) during replacement.

Technical Specifications

Compatibility

This genuine ZF part is engineered for the WG 200 series, including models WG200, WG180, and WG210 variants. It integrates directly with the COVER PLATE (4644301298) assembly and requires a fresh O-RING (0634306323) for proper sealing. The 4642.199.797 also fits select WG150 and WG250 units when used with the correct TRANSMISSION HOUSING (4644101249) or TRANSMISSION HOUSING (4644301402). Always verify your transmission serial number before ordering.
