Overview
The ZF 4657.183.287 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential fasteners, seals, and positioning elements required to secure the main transmission housing sections during rebuild or repair. The SKU 4657.183.287 ensures that all loose hardware—including bolts, pins, and retaining plates—meets ZF’s exacting tolerances for clamping force and vibration resistance. When replacing major structural components like the TRANSMISSION HOUSING or the HOUS.FRONT SECT, this loose parts kit is mandatory to maintain proper alignment and prevent fluid migration between chambers.
Symptoms of Failure
When the components within the 4657.183.287 kit degrade or are improperly torqued, operators typically encounter these specific failure modes:
- External oil seepage at housing joints: Worn or missing fasteners allow the HOUSING REAR PART to separate slightly, causing ATF to weep under pressure.
- Intermittent gear engagement hesitation: Loose hardware in the rear section leads to micro-movement of the HOUSING REAR SECTION, misaligning shift rails.
- Abnormal driveline vibration during load shifts: Degraded fixing plates or cap screws fail to dampen harmonic resonance between the front and rear housing assemblies.
- Contaminated oil from debris ingress: Gaps caused by missing cylindrical pins allow road grit to enter the clutch pack area.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my WG210 instead of buying the 4657.183.287 kit?
A: ZF explicitly discourages reusing cap screws and cylindrical pins due to torque-to-yield stretching. The 4657.183.287 kit provides new, pre-coated fasteners that ensure correct clamp load and prevent housing distortion.
Q: Does this kit include the screen sheets for the valve body?
A: Yes. The 4657.183.287 LOOSE PARTS kit contains both the 4657301032 and 4657301033 screen sheets, along with the FIXING PLATE to secure them.
Q: Will this part work with a ZF WG180 transmission?
A: Yes, the 4657.183.287 kit is mechanically interchangeable with WG180 and WG200 series housings, provided you also replace the TRANSMISSION HOUSING gasket set separately.
