Overview
This genuine OEM part, the ZF 4657.183.009 LOOSE PARTS set, is a critical service kit designed specifically for the WG 210 series transmission. It contains the essential small components required to secure and seal the main structural elements of the gearbox. Positioned at the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, this kit ensures proper alignment and oil-tight integrity. The SKU 4657.183.009 is frequently ordered during a full rebuild to replace all loose hardware that cannot be reused, preventing future mechanical play and fluid loss.
Symptoms of Failure
When the components within the 4657.183.009 LOOSE PARTS kit degrade or are missing, operators will notice distinct operational issues. The most common symptom is external oil seepage at the housing mating flanges, often mistaken for a gasket failure. Another clear indicator is abnormal gear rattle or vibration during acceleration, caused by loose fasteners allowing the housing sections to shift. Technicians also report erratic shift timing as internal clearances change, and in severe cases, metal debris in the oil pan from sheared retaining pins. Addressing these failures early with this genuine kit avoids costly damage to the HOUSING REAR PART.
