ZF 4657.183.154 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.154 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 210 series transmission. This assembly contains the essential loose components—including seals, retainers, and positioning elements—that secure internal sub-assemblies within the main gear case. As a precision-engineered replacement package, SKU 4657.183.154 restores the original clamping force and alignment between the TRANSMISSION HOUSING and the HOUS.FRONT SECT. Without these loose parts, the entire WG210 clutch pack and planetary gearset cannot maintain proper axial play, leading to premature wear across the drivetrain.

Symptoms of Failure

• Intermittent gear slipping under load: When the 4657.183.154 loose parts lose their retention integrity, the HOUSING REAR PART can shift, causing clutch packs to slip during torque transfer.
• Oil seepage at housing mating flanges: Worn or missing loose parts allow the CYLINDRICAL PIN to loosen, breaking the seal between the front and rear housing sections.
• Metallic rattling from the bell housing: Degraded fasteners within this kit permit the screen sheets and oil feed housing to vibrate against the case wall.
• Delayed engagement when shifting from Neutral to Drive: Insufficient clamping from the loose parts set reduces hydraulic pressure to the forward clutch circuit.

Technical Specifications

Compatibility

This OEM genuine loose parts kit is engineered for the ZF WG 210 series, but it also cross-fits select earlier models. Verified compatible transmissions include the WG180, WG200, and WG210 variants used in off-highway trucks, wheel loaders, and mobile cranes. The 4657.183.154 set directly replaces the fastening hardware for the TRANSMISSION HOUSING and HOUS.FRONT SECT interfaces. Always confirm your transmission serial number against the ZF parts catalog before ordering, as the WG215 and WG250 series require a different loose parts configuration.
