ZF 4644.199.971 LOOSE PARTS for WG200 | OEM Genuine Part

Overview

The ZF 4644.199.971 LOOSE PARTS kit is a critical service component designed specifically for the WG 200 series transmission. This genuine OEM assembly contains the essential fasteners, seals, and small hardware required to secure and seal internal transmission elements during a rebuild or major repair. The SKU 4644.199.971 is typically installed within the main valve body or clutch housing area, ensuring that loose components remain properly torqued and aligned under high-load conditions. When paired with a new TRANSMISSION HOUSING (4644101216) or a TRANSMISSION HOUSING (4644301223), this kit restores the structural integrity of the gearbox assembly.

Symptoms of Failure

When the ZF 4644.199.971 LOOSE PARTS kit deteriorates or is improperly installed, operators will notice distinct failure modes. Oil seepage around the transmission housing joints is a primary indicator, often accompanied by intermittent gear slippage under load due to loosened valve body bolts. Another common symptom is audible rattling or vibration from the bell housing area, suggesting that internal fasteners have backed out. Finally, erratic shift timing or delayed engagement can occur when these loose parts fail to maintain proper hydraulic pressure within the WG200 series.
