When there is a break in the propeller shaft, the usual thing to do is to use a universal joint. The tool is commonly used to secure the shaft to the shaft of the airboat. However, many of us are not aware that it is not always the best choice for repairing propeller shafts. There are many reasons why you should never use a universal joint when repairing your shaft.
As I mentioned above, the best option to repair a broken propeller shaft is to use a universal joint. The only problem with this tool is that it's costly and can be found in almost any boat supply stores. It's also fairly difficult to find replacement parts.
Here's another reason a universal joint is rarely used. The shaft and its bearing are both made from steel. When you use a universal joint to join them, you may cause the shaft to crack or bend, which would certainly require replacing it altogether.
Some tools just don't cut it to join these materials properly, so you'll have to make the shaft fit and make it fit the right shape. The cost of the universal joint is pretty high too. Since you will be using this to join several shafts to your airboat, you will pay several hundred dollars in the end.
Let's take a look at why a universal joint is used in propeller shaft maintenance. The shaft is one of the most critical components on your airboat. It is the one piece that holds everything together. It's a basic requirement that you replace it every time you have a problem with it.
One of the problems that regularly occur when working on a propeller shaft is either a melted part or damaged bearings. Mashed parts are caused by a buildup of excessive heat inside the shaft. For instance, when you turn the propeller on and get it going, the friction increases. The more friction you experience, the faster the shaft spins, and the harder it works.
Now the shaft is reaching its maximum performance, it simply cannot take it anymore. It over-heat and spits out the melted metal to the atmosphere.
Bearings are exactly what they sound like: they are a piece of metal that holds the shaft together. They are also a major component that wears out over time. When the bearings are worn out, you cannot apply as much force to the shaft, thus reducing friction and speeding up the process.
Mashed parts are common in damaged bearings. The reason is that damaged bearings break down and leave behind sharp edges and chips that can lead to melted parts and more abrasive chips.
The reason why you must replace the shaft if you notice it is wearing out is that it is the main connection between your propeller and your motor. Without it, you will not be able to make full-throttle turns. If the shaft fails, you may even lose control of your boat, and that's not something you want to happen.
Another reason why the universal joint is used in propeller shaft maintenance is that when used improperly, it could get out of balance. If the shaft is already out of balance, then it will not rotate properly and will either need to be replaced entirely or a new one installed.
Last but not least, it has to be said that why the universal joint is used in propeller shaft maintenance is because you can use it with just about any shaft. With just about any shaft, it will hold it in place.
