How is the end of a tailshaft fitted?
How is the end of a tailshaft fitted?
A large nut is fastened and locked in place on the end of the tailshaft: a cone is then bolted over the end of the tailshaft to provide a smooth flow of water from the propeller. One method of keyless propeller fitting is the oil injection system.
When to reject a tailshaft marine survey shaft?
Therefore if crack depth deeper than 1.5 % or shaft diameter (shaft being rule size) the shaft shall be rejected. Repairs of corroded or cracked shafts within limits given above shall be smoothly ground out to reduce stress concentrations to a minimum. The hollows should be filled with propriety metal filler if in way of sealing rings etc.
How is oil injected into a tailshaft propeller?
A large nut is fastened and locked in place on the end of the tailshaft: a cone is then bolted over the end of the tailshaft to provide a smooth flow of water from the propeller. One method of keyless propeller fitting is the oil injection system. The propeller bore has a series of axial and circumferential grooves machined into it.
What should be included in a tailshaft survey?
In the case of initial clearances drawings should be checked and for special materials such as “Tufnol” the manufacturer’s technical information should be heeded to allow for expansion of the bearing material on submersion in water. 1.2.2 Propeller shafts running in white metal bearings – oil lubricated.
Therefore if crack depth deeper than 1.5 % or shaft diameter (shaft being rule size) the shaft shall be rejected. Repairs of corroded or cracked shafts within limits given above shall be smoothly ground out to reduce stress concentrations to a minimum. The hollows should be filled with propriety metal filler if in way of sealing rings etc.
Can a bad shaft bearing cause an oil leak?
If the output shaft bearing becomes damaged, it can cause gear oil to leak from the transmission. An oil leak from the transfer case will put the unit at risk of running low and suffering damage due to lack of lubrication.

Where is the front output shaft bearing located?
A front output shaft bearing is a component that is commonly found on vehicles equipped with transfer cases, such as all wheel and four-wheel drive vehicles. The front output shaft bearing is the heavy duty bearing installed in the vehicle’s transfer case that supports and secures the front output shaft into place.
