20860656 Actuator | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta actuator used in the special-function hydraulic arrangement on selected TAD76-series installations.

⚙️ Key Features

• Genuine Volvo Penta Hydraulic Auxiliary-Function Actuator - part number 20860656
• Application-specific actuator for the Volvo Penta hydraulic/PTO arrangement
• Works with the corresponding hydraulic pump and mounting hardware
• Controlled travel and mounting geometry preserve the required operating range
• Designed for vibration, heat and repeated duty in an engine installation
• Electrical, pneumatic or hydraulic connection must match the original configuration
• Confirm engine serial number, option code and actuator linkage before ordering
• Engine type: D7-series industrial engine hydraulic/PTO special-function installations

🔌 Function

The actuator receives a control command and moves the associated lever, valve or pump-control element through a calibrated stroke. This allows the engine's auxiliary hydraulic function to engage, regulate or return to its safe position as designed.

⚠️ Common Signs of Failure

• Auxiliary function fails to engage or disengage
• Slow, incomplete or erratic actuator travel
• Fluid leakage or damaged electrical connection, as applicable
• Linkage binds or does not return to its rest position
• Control-system warning or repeated actuator-position fault

🛠️ Service Notes

• Note the fitted position and any linkage settings before removal, so the new unit can be set up the same way
• Isolate the batteries, and relieve any pressure in the system, before disconnecting an actuator
• Check the linkage, pivots and mountings move freely; a stiff or seized mechanism will kill a new actuator as surely as it killed the old one
• Fit it so it works through its full travel without binding and reaches both end positions properly, with the connector seated dry and locked
• Some actuators need calibration or a learning procedure with Volvo Penta diagnostic equipment before they will operate correctly, so check what your engine requires
