Overview
The ZF 4681.271.001 CLUTCH is a critical internal component engineered specifically for the BP 210 and BP 230 series transmissions. This OEM genuine part functions as the primary torque-transfer interface, engaging and disengaging the driveline to enable smooth gear shifts and controlled power delivery. Positioned within the main shaft assembly, the clutch directly interacts with the TRANSMISSION HOUSING to maintain alignment and structural integrity. The SKU 4681.271.001 is manufactured to ZF’s exacting tolerances, ensuring a precise fit and reliable operation under high-load industrial conditions.
Symptoms of Failure
- Delayed or harsh gear engagement: When the clutch disc wears thin, you may notice a lag between shifting and actual gear engagement, or a jarring “clunk” as the transmission catches up.
- Torque converter shudder at low RPM: A worn 4681.271.001 clutch can cause vibration or shuddering during acceleration from a stop, particularly in BP 230 series units.
- Oil contamination with friction material debris: As the clutch lining degrades, fine particles enter the hydraulic circuit, often clogging the SCREEN SHEET and reducing system pressure.
- Slipping under load: A failing clutch will allow the engine RPM to rise without a corresponding increase in vehicle speed, especially when climbing grades or carrying heavy loads.

Compatibility
This clutch is a direct replacement for ZF BP 210 and BP 230 series transmissions. It is also compatible with the following ZF models that share the same clutch pack architecture: WG180, WG200, WG210, and WG230. The part integrates with the HOUS.FRONT SECT and the HOUSING REAR PART to form the complete clutch drum assembly. For proper installation, ensure the CASE is free of scoring and the pilot bearing bore is within specification.

Frequently Asked Questions
Q: How do I know if the 4681.271.001 clutch is the correct part for my BP 210?
A: Verify your transmission model number on the data plate. This clutch fits all BP 210 and BP 230 series units, as well as WG180 through WG230 models. If your unit has a 271 mm clutch drum diameter, this is the correct part.
Q: Should I replace the screen sheets when installing a new clutch?
A: Yes. We strongly recommend replacing both the SCREEN SHEET (4681301016) and the SCREEN SHEET (4681301017) simultaneously, as worn clutch debris often contaminates these filters.
Q: What torque specification is required for the cap screws holding the fixing plate?
A: Use 25 Nm for the CAP SCREW (0636100801) and 40 Nm for the CAP SCREW (0636100803). Always use a torque wrench to avoid distortion of the clutch pack.
