Overview

The ZF 4657.183.433 LOOSE PARTS kit is a critical OEM genuine service set designed specifically for the WG 190 series transmission. This assembly group contains the essential fasteners, seals, and positioning components required to secure the main transmission housing sections during rebuild or repair. As a loose parts kit, it replaces all worn or damaged hardware that can compromise the structural integrity of the gearbox. The SKU 4657.183.433 is factory-matched to ensure precise fitment when paired with the TRANSMISSION HOUSING, providing the necessary clamping force and alignment for long-term reliability.

Symptoms of Failure

When the components in this loose parts kit degrade, operators often notice transmission oil weeping from housing seams due to compromised bolt tension. A second common failure is gear engagement hesitation or slipping caused by housing misalignment. Technicians also report abnormal vibration during torque converter lockup when the front section fasteners lose their preload. Finally, difficulty shifting between forward and reverse gears can indicate that the rear housing section has shifted out of tolerance, requiring immediate replacement of the 4657.183.433 kit.
