Overview
The ZF 4651.183.040 LOOSE PARTS for BP210 is a critical service kit designed to restore the internal integrity of your BP 210 series transmission. This OEM genuine assembly contains the essential loose components required to maintain proper clutch pack clearance and hydraulic pressure within the gear train. Identified by SKU 4651.183.040, this kit sits directly within the main shaft assembly, acting as a precision spacer and retention set that ensures the planetary gearsets remain correctly indexed. When replacing major structural components such as the TRANSMISSION HOUSING or the HOUS.FRONT SECT, this loose parts kit is mandatory for re-establishing factory tolerances.
Symptoms of Failure
- Erratic gear engagement and delayed shifting: When the 4651.183.040 components wear, you will notice a pronounced hesitation when shifting from Neutral to Drive or Reverse, often accompanied by a harsh “clunk.”
- Low hydraulic pressure warnings: Worn loose parts within the BP210 can cause internal leakage, triggering diagnostic trouble codes for low main pressure, especially under heavy load.
- Metallic debris in the transmission pan: As the retaining elements fatigue, small metal particles will appear in the fluid, indicating that the HOUSING REAR PART or HOUSING REAR SECTION may also be compromised.
- Intermittent loss of forward or reverse motion: A sudden inability to move the vehicle after a stop, followed by a temporary return of function, is a classic sign of failing internal loose parts.

Frequently Asked Questions
Q: Can I install the 4651.183.040 loose parts kit without replacing the housing sections?
A: Yes, but we strongly recommend inspecting the HOUSING REAR PART and HOUSING REAR SECTION for wear. Worn housings can cause premature failure of the new loose parts.
Q: How do I know if this kit fits my specific BP210 transmission?
A: Verify the transmission tag located on the TRANSMISSION HOUSING. The SKU 4651.183.040 is designed for all BP210 variants with a serial number prefix of “BP210-“.
Q: What is the typical lifespan of these loose parts?
A: Under normal operating conditions, the 4651.183.040 components last 300,000 to 500,000 miles. However, if you experience the symptoms listed above, immediate replacement is advised to avoid damage to the HOUS.FRONT SECT.
