Overview
The ZF 4657.183.015 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 series transmission. This genuine OEM part contains the essential small components—including seals, retainers, and fasteners—required to properly secure and seal the main housing sections during a rebuild or overhaul. Without this kit, the structural integrity of the gearbox is compromised, leading to fluid migration and potential internal contamination. The SKU 4657.183.015 is engineered to match factory tolerances, ensuring that the TRANSMISSION HOUSING and its adjoining sections remain perfectly aligned under high torque loads.
Symptoms of Failure
- External oil seepage at housing joints: When the loose parts in this kit degrade, you will notice fluid weeping between the HOUS.FRONT SECT and the main casing, especially after extended operation.
- Gear slippage under load: Worn retaining elements allow the HOUSING REAR PART to shift minutely, causing intermittent loss of hydraulic pressure and clutch pack disengagement.
- Abnormal vibration or driveline noise: A loose CYLINDRICAL PIN within the assembly can create a knocking sound during gear changes, indicating that the structural alignment is failing.
- Contaminated transmission fluid: Failed seals in the loose parts set allow dirt and debris to enter the oil circuit, accelerating wear on clutches and bearings.

Compatibility
This genuine ZF 4657.183.015 LOOSE PARTS kit is primarily designed for the WG 210 transmission series. Based on its structural role, it is also compatible with the WG 180 and WG 200 series, as these models share the same housing interface geometry. The kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, and it secures the HOUSING REAR PART using the included CYLINDRICAL PIN. Always verify your transmission model tag before ordering.

Frequently Asked Questions
Q: Can I use this 4657.183.015 kit on a WG 180 transmission?
A: Yes, the loose parts kit is cross-compatible with WG 180 and WG 200 series transmissions, as the housing bolt patterns and pin locations are identical to the WG 210.
Q: What is the typical lifespan of these loose parts before replacement is needed?
A: Under normal operating conditions, the seals and pins in this kit last approximately 500,000 miles or 10 years. Replace immediately if you observe any oil seepage at the housing joints.
Q: Do I need to replace the CYLINDRICAL PIN separately if I buy this kit?
A: No. The 4657.183.015 kit includes the CYLINDRICAL PIN and all necessary fasteners, so no additional parts are required for a full housing reseal.
