Overview
The ZF 4642.199.455 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 200 series transmission. This assembly contains the essential loose hardware and fasteners required to secure internal components during a rebuild or major repair. Positioned within the main gear train housing, this kit ensures that shift forks, bearing retainers, and clutch packs remain properly torqued under extreme operational loads. The SKU 4642.199.455 is the factory-authorized replacement for worn or damaged loose parts, guaranteeing exact fitment and preventing premature wear on adjacent assemblies such as the 4644101223: TRANSMISSION HOUSING and the 4644301225: TRANSMISSION HOUSING.
Symptoms of Failure
When the ZF 4642.199.455 LOOSE PARTS begin to degrade, operators will notice distinct operational issues. Transmission housing oil seepage often occurs around the bolt bosses if the fasteners lose their clamping force. Intermittent gear slipping under load is a common complaint, as loose hardware allows shift forks to drift out of alignment. Abnormal metallic rattling from the bell housing indicates that retaining clips or washers have fatigued. Finally, difficulty engaging reverse or low range can be traced back to loose parts compromising the shift rail alignment. Addressing these symptoms early with the genuine 4642.199.455 kit prevents cascading damage to the 0730365125: TYPE PLATE and the 4644301298: COVER PLATE.
