ZF 4616.199.140 LOOSE PARTS for WG65 | OEM Genuine Part

Overview

The ZF 4616.199.140 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 65 Series transmission. This assembly consolidates essential hardware and sealing elements required during a major overhaul or when replacing the main transmission housing. The SKU 4616.199.140 ensures that all loose components—including fasteners and gaskets—are matched precisely to factory tolerances, preventing contamination and maintaining hydraulic pressure integrity. When paired with a new TRANSMISSION HOUSING, this kit guarantees a leak-free seal and secure mounting of internal valve bodies.

Symptoms of Failure

• External oil seepage around the housing flange: Worn or degraded loose parts cause fluid to escape, leading to low transmission fluid levels and eventual gear slippage.
• Persistent hexagon screw loosening: If the original fasteners fatigue, you may hear rattling or experience vibration during gear shifts, indicating the need for replacement screws like the HEXAGON SCREW.
• Intermittent pressure loss: Damaged sealing elements within the loose parts set allow air ingress, resulting in delayed engagement or harsh shifting in WG65 transmissions.
• Contaminated fluid from loose debris: Broken hardware can shed metal particles into the oil circuit, accelerating wear on clutches and bearings.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 65 Series, but its hardware and sealing profile also apply to closely related models. It is commonly used in the WG180, WG200, and WG250 transmissions where the housing bolt pattern and O-ring grooves match the WG65 design. Always verify the specific housing variant; the kit integrates with the HEXAGON SCREW and HEXAGON SCREW to secure the valve body assembly. For additional sealing, the O-RING and SEALING RING are included in the set to prevent fluid bypass.
