In vehicles the tailshaft transfers power from the gearbox to the differential, as opposed to a driveshaft which transfers power from the differential to the wheels or other mechanical parts, causing rotation.
Tailshafts in marine vehicles refer to the rear section of a ship’s propeller shaft. It is usually a metallic rod which holds the propeller and is connected to the power engine.
In any vehicle they can endure a large amount of stress and torsion (twisting). While they are designed to carry these forces, over time they can become damaged or out of balance, affecting the performance of the vehicle.
Simple wear and tear can cause tiny deviations from “true”, like a quarter of a thousandth, but this is enough to cause an unbalancing effect and potentially serious (and expensive) issues.
Maintaining and Repairing Tailshafts
In standard road vehicles, a slightly out of balance tailshaft can cause problems of safety and performance, but is generally manageable.
In heavy industrial vehicles, trucks, mining vehicles, marine vehicles and high speed racing cars, problems are multiplied and magnified and require highly specialised engineering and balancing equipment to repair them.
Such problems may also point to other deep-lying issues with the mechanics of the vehicle, like universal joint failure.
It takes properly-licensed and experienced specialists to repair such problems with high performance vehicles. A licensed specialist will be able to carry out repairs on site and return your vehicle to tip-top condition, re-balancing or rebuilding the tailshaft to ensure maximum safety and reliability into the future.
