Overview
The ZF 4651.183.041 LOOSE PARTS for BP230 is an OEM genuine component designed to secure and stabilize critical internal assemblies within the BP 230 series transmission. This part functions as a retention and alignment kit, ensuring that key elements such as the TRANSMISSION HOUSING and the HOUS.FRONT SECT remain correctly positioned under high torque and thermal stress. The SKU 4651.183.041 is specifically engineered for the BP230 series, where it acts as a loose-parts kit containing fasteners, spacers, and positioning elements. Without this kit, the transmission’s structural integrity can be compromised, leading to misalignment of the HOUSING REAR PART and the HOUSING REAR SECTION.
Symptoms of Failure
- Transmission oil leaks at housing joints: When the 4651.183.041 loose parts degrade, the clamping force between the front and rear housing sections diminishes, allowing transmission fluid to seep out along mating surfaces.
- Intermittent gear slipping under load: Worn or missing components from this kit can cause the TRANSMISSION HOUSING to shift slightly, resulting in gear engagement issues that worsen during heavy acceleration.
- Abnormal vibration or driveline noise: A loose housing assembly due to failed retaining parts creates play in the drivetrain, producing a low-frequency hum or knocking sound during deceleration.
- Difficulty shifting between forward and reverse: Misalignment of the HOUS.FRONT SECT relative to the rear section can bind the shift mechanism, requiring excessive force to change gears.

Compatibility
This OEM genuine part is primarily designed for the ZF BP230 transmission series. Based on its structural role, it is also compatible with the following ZF models that share similar housing architectures: WG180, WG200, WG210, and HP500. The 4651.183.041 kit is essential for any rebuild involving the HOUSING REAR PART or the HOUSING REAR SECTION, as it provides the necessary fasteners to maintain factory tolerances. Always verify your transmission’s serial number before ordering.

Frequently Asked Questions
Q: Can I reuse the 4651.183.041 loose parts during a rebuild?
A: ZF recommends replacing this kit entirely during any major overhaul. The fasteners and clips are designed for single-use torque retention, and reusing them can lead to loosening over time.
Q: Does this kit include all necessary hardware for the BP230 housing?
A: Yes, the 4651.183.041 contains the specific clips, dowels, and shims required to mount the TRANSMISSION HOUSING and both front and rear sections. However, cap screws like 0636100801 are sold separately.
Q: How do I verify if this part fits my ZF transmission?
A: Check the transmission model plate for BP230, WG180, or WG200 series. If the housing uses a split-case design with a separate HOUS.FRONT SECT and rear section, this kit is compatible.
