Overview
The ZF 4657.183.294 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This OEM genuine part set contains the necessary hardware and small components required to secure and align internal assemblies within the gearbox. As a loose parts package, it functions as a consolidation of fasteners, spacers, and alignment aids that are essential when rebuilding or servicing the main transmission housing. The SKU 4657.183.294 is typically replaced during a major overhaul to ensure all mounting points meet factory torque specifications. This kit works in direct conjunction with the 4657101082: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to maintain structural integrity under high-load conditions.
Symptoms of Failure
When the ZF 4657.183.294 LOOSE PARTS begin to degrade or are missing, operators will notice distinct operational issues. Oil seepage at the housing joint is a primary indicator, as the included seals and bolts lose their clamping force. Abnormal gear rattle or vibration during acceleration occurs when internal alignment pins become loose, allowing the 4657201170: HOUSING REAR PART to shift slightly. Intermittent loss of hydraulic pressure can develop if the fasteners securing the valve body interface are compromised. Finally, difficulty engaging forward or reverse gears may arise when the loose parts fail to maintain proper spacing between the 4657298102: HOUSING REAR SECTION and the main case.
