ZF 4616.199.175 LOOSE PARTS for WG65 | OEM Genuine Part

Overview

The ZF 4616.199.175 LOOSE PARTS kit is a critical service component designed specifically for the WG 65 Series transmission. This OEM genuine part consolidates essential hardware elements that secure and stabilize internal assemblies within the gearbox. As a loose parts set, it provides the necessary fasteners and spacers to maintain precise alignment of the clutch and planetary gear sets. The SKU 4616.199.175 is frequently ordered during major overhauls to replace worn or damaged hardware, ensuring the transmission housing remains properly sealed and structurally sound under high-torque conditions.

Symptoms of Failure

When the components within the 4616.199.175 LOOSE PARTS kit degrade, operators often notice distinct operational issues. Transmission oil leaks from the main casing joints are a primary indicator, as degraded hardware compromises seal integrity. Another common symptom is gear slipping under load, particularly during upshifts, caused by loosened fasteners allowing internal components to shift. You may also experience abnormal vibration or rumbling from the transmission housing, which signals that critical spacers have fatigued. Finally, difficulty engaging reverse gear can occur when the loose parts fail to maintain proper axial clearance within the WG65 assembly.

Technical Specifications

Compatibility

This LOOSE PARTS kit is engineered for the ZF WG 65 transmission family, but its hardware design also supports several other ZF models that share the same casing architecture. It is directly compatible with the WG180, WG200, and WG250 series transmissions. Additionally, the 4616.199.175 set can be used in WG120 and WG150 units during rebuilds, provided the main housing is from the same generation. Always verify that the 4616101137: TRANSMISSION HOUSING and 4616301304: HOUSING are in good condition before installing this kit.

During installation, the loose parts interact directly with the 4616301309: HOUSING to ensure proper torque distribution. For complete assembly integrity, we recommend pairing this kit with a new 0636011118: HEXAGON SCREW set to achieve factory-specified clamping forces.
