ZF 4657.183.358 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.358 LOOSE PARTS assembly is a critical service kit designed for the WG 210 series transmission. This OEM genuine part includes all necessary fasteners, seals, and positioning components required to secure and align the main housing sections during rebuild or repair. Specifically, this kit interfaces directly with the 4657101082: TRANSMISSION HOUSING, ensuring a precise fit between the 4657201166: HOUS.FRONT SECT and the 4657201170: HOUSING REAR PART. The SKU 4657.183.358 is often ordered alongside the 4657298102: HOUSING REAR SECTION to complete a full structural overhaul of the gearbox.

Symptoms of Failure

When the loose parts in this kit degrade or are missing, operators typically encounter these specific failure modes:

• Transmission fluid seepage at housing joints: Worn gaskets or loose fasteners cause oil to weep between the front and rear housing sections.
• Abnormal gear rattle or vibration: Missing positioning pins allow the housing halves to shift slightly under load, creating audible noise.
• Difficult gear engagement: Misalignment of the housing sections due to degraded locating components leads to binding in the shift mechanism.
• Recurring bolt loosening: If the cap screws lose torque retention, the entire assembly can develop play, accelerating wear on internal bearings.

Technical Specifications

Compatibility

This loose parts kit is engineered specifically for the ZF WG 210 series, but it also cross-references with several other ZF off-highway transmissions. The kit is fully compatible with WG 180, WG 200, and WG 211 models that share the same housing bolt pattern. It is not recommended for WG 120 or WG 150 series due to different fastener lengths. Always verify the housing part numbers before ordering: the 4657101082: TRANSMISSION HOUSING and 4657201166: HOUS.FRONT SECT must match the kit revision.
