Aquadrive 6040453 – CV21 Adapter Flange 4" for ZF HBW / HSW450D, TMC40-60, PRM 80-150 Gearboxes
The Aquadrive 6040453 Adapter Flange is designed to connect Aquadrive propulsion systems with compatible marine gearboxes. It forms the mechanical interface between the gearbox output flange and the Aquadrive constant velocity drivetrain assembly.
This adapter flange is engineered for Aquadrive CV21 propulsion systems (CVB21.20) and is compatible with several marine transmission models including ZF HBW, ZF HSW, TMC and PRM gearboxes. Precision-machined mounting geometry ensures proper drivetrain alignment and reliable installation.
Selecting the correct Aquadrive adapter flange is essential for proper system integration. The adapter allows the Aquadrive thrust bearing and constant velocity shaft assembly to connect correctly to the gearbox flange, helping maintain smooth torque transmission while reducing drivetrain vibration and misalignment loads.
