Overview
The ZF 4642.199.387 LOOSE PARTS for WG200 is a critical service kit designed to restore the internal sealing and fastening integrity of the WG 200 series transmission. This OEM genuine part, identified by SKU 4642.199.387, contains the specific loose hardware and sealing elements required to secure the 4644101216: TRANSMISSION HOUSING and the 4644301223: TRANSMISSION HOUSING during a major overhaul. Without this kit, reassembly of the main casing is not possible, as it provides the necessary fasteners and seals to prevent fluid migration and structural loosening.
Symptoms of Failure
When the components within the 4642.199.387 kit begin to degrade or are missing, operators will notice specific operational issues. Common failure symptoms include:
- External oil seepage at housing joints: Worn seals or missing fasteners from this kit allow transmission fluid to escape, leaving visible drips on the bell housing.
- Transmission gear slipping under load: Loose internal hardware can cause the valve body or clutch packs to shift position, leading to intermittent power loss.
- Abnormal vibration or rattle from the transmission casing: If the 0631311009: GROOVED STUD is compromised, the housing may not clamp evenly, creating audible noise.
- Incorrect identification after service: A missing 0730365067: TYPE PLATE can lead to confusion during rebuilds, as the transmission model cannot be verified.
