Tunnel Thruster · Bow/Stern Thrusters
Inspecting and maintaining a TT-500 stern tunnel thruster involves careful attention to several critical components. Regularly check for wear on propeller blades and their O-rings, ensuring they remain free of damage and maintain proper operation. The propeller well’s sealing should be inspected for leaks or oil leakage signs, with any issues addressed promptly to prevent water ingress. Axial and radial play in the bearings must also be monitored; exceeding normal values could indicate wear that needs addressing. Hydraulics require periodic checks for contamination, moisture, and fluid degradation, with filters replaced according to manufacturer guidelines. Overall, diligent maintenance is crucial to ensure the longevity and reliability of this powerful thruster system.
