ZF 4616.199.171 LOOSE PARTS for WG65 | OEM Genuine Part

Overview

The ZF 4616.199.171 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 65 Series transmission. This OEM genuine part contains the necessary loose components required to maintain proper internal clearances and secure mounting within the gearbox housing. Positioned within the main casing assembly, this kit ensures that all fasteners, seals, and positioning elements remain intact during high-torque operations. The SKU 4616.199.171 is factory-matched to ZF’s original specifications, guaranteeing a direct fit without modification. When paired with a new 4616101116: TRANSMISSION HOUSING, this loose parts set restores the structural integrity of the WG65 unit.

Symptoms of Failure

• Transmission oil weeping from casing joints: Worn or missing loose parts can cause sealing surfaces to separate, leading to slow oil loss around the housing flanges.
• Audible rattling or knocking from the bell housing: Loose fasteners within the 4616.199.171 set allow internal components to shift, creating metallic noise during gear changes.
• Intermittent gear engagement hesitation: When these parts degrade, alignment of the shift mechanism becomes compromised, resulting in delayed or rough engagement.
• Vibration at highway speeds: A failing loose parts kit can unbalance the transmission assembly, transmitting excessive vibration through the driveline.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 65 Series transmissions, including models such as WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is also suitable for select off-highway and marine variants sharing the same housing architecture. For proper installation, always verify that the 0636011118: HEXAGON SCREW and the 4616301307: HOUSING are inspected concurrently. Additionally, the 4616301309: HOUSING must be checked for wear to ensure a complete seal.
