Overview
The ZF 4657.183.347 LOOSE PARTS set is a critical service kit designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential loose components required to rebuild or repair the internal shifting mechanism and hydraulic control system. Positioned within the valve body and clutch pack area, these parts ensure precise oil flow and gear engagement. The SKU 4657.183.347 is a factory-sealed kit that includes all necessary seals, springs, and retaining elements to restore factory performance. When paired with a new TRANSMISSION HOUSING, this kit eliminates common wear-related failures in high-mileage units.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn loose parts cause sluggish shifts between forward and reverse, often accompanied by a noticeable clunk. This is a common search query for “ZF WG210 hard shifting fix.”
- Intermittent oil leaks around the valve body: Degraded seals within the 4657.183.347 kit lead to external fluid seepage, particularly near the HOUS.FRONT SECT interface.
- Slipping under load: When internal springs or pistons lose tension, the transmission fails to hold gear pressure, causing RPM flare during acceleration. This symptom often prompts searches for “WG210 slipping repair parts.”
- Erratic shift patterns: The transmission may skip gears or hunt between ratios due to loose detent components, requiring immediate replacement of the LOOSE PARTS kit.

Frequently Asked Questions
Q: Can I reuse old seals from the previous LOOSE PARTS kit?
No. The ZF 4657.183.347 kit is designed for single-use installation. Reusing seals will lead to immediate oil leaks and shift quality degradation.
Q: Does this kit include the CYLINDRICAL PIN (0631306816)?
No. The 4657.183.347 kit contains only the loose internal components. The CYLINDRICAL PIN and CAP SCREW must be ordered separately for a complete rebuild.
Q: How do I verify this part fits my WG210 transmission?
Check the transmission serial number plate. The 4657.183.347 is compatible with all WG210 variants produced after 2005. For earlier units, cross-reference with the FIXING PLATE part number to confirm bolt pattern.
