ZF 4657.183.371 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.371 LOOSE PARTS for WG210 is a critical internal component set designed to maintain precise hydraulic and mechanical clearances within the WG 210 series transmission. This OEM genuine part, identified by SKU 4657.183.371, functions as a collection of fasteners, seals, and positioning elements that secure the main valve body and clutch assemblies. Without these loose parts, the transmission cannot maintain proper oil pressure or gear engagement. This kit is typically installed during a full rebuild or when addressing internal wear, and it works in direct conjunction with the 4657101082: TRANSMISSION HOUSING to ensure all components remain seated under high torque loads.

Symptoms of Failure

• Erratic shifting or delayed engagement: When the 4657.183.371 loose parts degrade, the valve body can shift out of alignment, causing harsh or delayed gear changes. This is a common long-tail search query for “ZF WG210 shifting problems.”
• Internal oil leaks at housing joints: Worn seals or loose fasteners from this kit allow transmission fluid to escape between the 4657201166: HOUS.FRONT SECT and the main casing, leading to low fluid levels and overheating.
• Unusual metallic rattling from the bell housing: If the fixing plates or pins in this set become loose, they can vibrate against the 4657201170: HOUSING REAR PART, producing a distinct noise that worsens under load.
• Intermittent loss of drive: A failure of the positioning elements can cause the clutch pack to slip intermittently, often misdiagnosed as a solenoid issue.

Technical Specifications

Compatibility

This 4657.183.371 loose parts kit is specifically engineered for the ZF WG 210 series transmissions. However, due to shared architecture, it also fits the WG180, WG200, and WG250 models when used in conjunction with the correct 4657298102: HOUSING REAR SECTION. It is not compatible with the older WG120 series without additional adapter plates. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: Can I reuse the old fasteners from my WG210 instead of buying this loose parts kit?
A: No. ZF specifies that all cap screws and pins in the 4657.183.371 kit are single-use due to torque-to-yield requirements. Reusing them risks fastener fatigue and internal oil leaks.

Q: Does this kit include the screen sheets for the oil filter?
A: Yes. The 4657.183.371 set includes both the 4657301032: SCREEN SHEET and 4657301033: SCREEN SHEET as part of the standard package.

Q: How do I know if my transmission uses the WG210 or WG200 housing?
A: Check the casting number on the 4657201170: HOUSING REAR PART. If it ends in “1170,” it is a WG210 variant. If it ends in “1166,” it is a WG200.
