How Does the Lenco 2 1/4 Stroke Actuator Work?

This actuator functions by converting electrical energy from the 12V system into mechanical motion. When activated, it extends or retracts its piston rod (5/16″ diameter) up to 2 1/4 inches, adjusting the position of trim tabs on the boat hull. This adjustment controls the boat’s attitude on the water, improving handling and reducing drag.

The actuator’s sealed hydraulic system ensures smooth operation, while built-in overload protection prevents damage from excessive force or impacts. It’s compatible with various trim tab switch controls and can be integrated into manual or automatic trim tab setups.

Key Components of the Lenco 2 1/4 Stroke Actuator

Understanding the key components helps with installation and maintenance:

• Hydraulic Cylinder: Houses the piston and fluid for linear motion.
• Piston Rod (5/16″ Diameter): Transfers the force to the trim tabs.
• Electric Motor: Powers the hydraulic pump within the actuator.
• Seals and Bearings: Protect internal components from corrosion and wear.
• Mounting Brackets: Secure the actuator to the boat’s hull and trim tabs.

Maintenance Tips for Lenco 2 1/4 Stroke Actuator

To maximize the lifespan and efficiency of your Lenco 2 1/4 Stroke Actuator, regular maintenance is essential. Marine environments can be harsh due to saltwater exposure, UV rays, and constant vibration.

Here are some practical maintenance tips:

• Regular Cleaning: Rinse the actuator with fresh water after every trip to remove salt deposits and dirt.
• Lubrication: Apply marine-grade lubricant to pivot points and the piston rod to prevent corrosion and ensure smooth motion.
• Check Electrical Connections: Inspect and clean battery and wiring connections to avoid voltage drops and corrosion.
• Inspect Seals: Periodically check for hydraulic fluid leaks and replace seals as necessary.
• Winter Storage: If storing the boat in cold climates, ensure the actuator is retracted and protected from freezing conditions.
