Sourcing ZF Engine Connections: The Difference Between Basicpower (Trumpet) and Ergopower (Membrane) Flywheels
Sourcing ZF Engine Connections: The Difference Between Basicpower (Trumpet) and Ergopower (Membrane) Flywheels


Introduction: A Critical Mechanical Difference
When sourcing engine connection parts for a ZF transmission, a key mechanical difference exists between the Basicpower and Ergopower M series. They use different flywheel connection types, and ordering the wrong mounting parts (like the bell housing or intermediate ring) will halt your repair.
This guide from Tianjin XiaoHang Construction Machinery Co., Ltd. clarifies this difference, drawing on our 20 years of technical expertise.
Section 1: Ergopower M Series – The Membrane Connection
Flexible Plate Design
The Ergopower M series often utilizes a Membrane (a flexible diaphragm plate) to connect to the engine flywheel. This design requires specific mounting components.
Section 2: Basicpower Series – The Trumpet Connection
Rigid Bell Housing Design
The Basicpower series (including 4BP230) typically uses a Trumpet style connection, which is a more rigid bell housing design, similar to the older WG200 series. This requires a different set of mounting hardware.
- Key Part Example: For a 4BP230 (BOM 4681.084.018), this assembly includes the main CONVERTER BELL 4681.330.001 and the INTERMEDIATE RING 4681.330.011. These parts are not compatible with a Membrane-style connection.
