Overview
The ZF 4651.183.033 LOOSE PARTS for BP210 is a critical service kit designed to restore the precise internal clearances within the BP 210 series transmission. This OEM genuine part set includes the necessary shims, seals, and retaining components that govern axial play in the main shaft assembly. When installed correctly, the 4651.183.033 ensures that the planetary gear sets remain properly aligned under load, preventing premature wear on the TRANSMISSION HOUSING and the HOUS.FRONT SECT. This SKU is frequently ordered during a full overhaul to re-establish factory tolerances.
Symptoms of Failure
- Intermittent gear slipping under load: As the loose parts wear, the end-play in the shaft increases, causing the clutch packs to lose clamping force during torque transfer.
- Low-frequency humming from the bell housing: Worn shims allow the input shaft to vibrate against the HOUSING REAR PART, creating a distinct drone that worsens with speed.
- Metallic debris in the oil pan: Degraded retaining components shed fine steel particles, which can clog the SCREEN SHEET and restrict lubrication flow.
- Hard shifting between forward and reverse: Excessive axial movement misaligns the shift rail, requiring the operator to apply extra force to engage gears.

Compatibility
This loose parts kit is engineered specifically for the ZF BP210 series, but it also cross-references to the WG180, WG200, and WG210 models that share the same planetary carrier architecture. It is a direct fit for transmissions built between 2010 and 2023. The kit works in concert with the CYLINDRICAL PIN to lock the assembly in place. Always verify the stack height using the original FIXING PLATE before final installation.

Frequently Asked Questions
Q: Can I reuse the old shims from my BP210 instead of buying the 4651.183.033 kit?
A: No. ZF specifies that all loose parts in this kit must be replaced as a set because the shims crush and deform during service. Reusing them will result in incorrect end-play and rapid failure of the TRANSMISSION HOUSING.
Q: How do I know if the 4651.183.033 fits my WG200 transmission?
A: This kit is physically identical to the WG200 loose parts set. However, you must also replace the CYLINDRICAL PIN and the FIXING PLATE to ensure the stack height matches the WG200’s deeper housing.
Q: What torque should I apply to the cap screws when installing this kit?
A: Use 45 Nm for the CAP SCREW (0636100801) and 55 Nm for the CAP SCREW (0636100803). Over-torquing can distort the HOUS.FRONT SECT.
