What are he common problems of an excavators? The maintenance that is required for small excavators is the same as that which is required for larger models, so don’t let their size deceive you. The following are five problems associated with compact excavators that need to be fixed.
- Watch out for the signs of stress.
One of the most frequently neglected service locations on compact excavators is the track tension. The most majority of them are equipped with rubber tracks, which require their operators to make the necessary adjustments in order to maximize their longevity. In addition to this, it reduces the amount of wear that is done to the track and the components of the track. A track that is not properly secured may experience accelerated wear, which will result in additional downtime and a halt in production while a new track is installed. On the other side, a track that is too tight can shred the rubber material and significantly increase the amount of wear that is done to the other components of the track system, such as traction motors, sprockets, and front idlers. Always referring to the operator’s manual and keeping a close eye on the track sag measurement are two things that operators should do on a routine basis to guarantee that the track tension is optimal.
- Put some lard or butter on it.
Operators frequently neglect to grease the pins and bushings during routine maintenance, despite the fact that grease is the pins’ and bushings’ primary source of lubrication. As a general rule, you should always make it a point to lubricate all of the pins and bushings on a daily basis. The operator’s manual will be of assistance in determining each grease location, as well as making recommendations regarding the quantity and quality of grease. It is a good idea to label less prominent grease spots, such as the turntable bearing, using orange marking paint around the grease nipple to serve as a reminder to all of the machine’s users if the machine is used by multiple operators at the same time. This can be done if there is only one machine.
Over-greasing, like under-greasing, can be detrimental. In most cases, one to three oil injections are all that is required to accomplish the work at hand. When there is an excessive amount, not only does it create a major mess but it also poses a threat to the surrounding ecosystem and is a waste of money.
- A gearbox that enables one to propel themselves forward is referred to as a propel drive gearbox.
The propel drive gearbox is one of the most significant components that contribute to the performance of a machine; however, when it comes to maintenance, this component is sometimes neglected. Since gearboxes are typically covered in mud, the fill and drain plugs tend to hide, which means that operators and service employees are rarely aware that they are there. On the other hand, gearboxes need to have their oil changed approximately every 1,000 hours, but this number can vary depending on the manufacturer. Even though gearboxes are very compact in size, they are nonetheless quite expensive to manufacture since they include the same internal components as their more substantial relatives, but on a more minute scale. They typically hold between half a quart and one quart of oil and can change fast in the majority of situations, so purchasing one is a little investment that can pay out in the long term.
- Hydraulic oil replacement
Because it breaks down and loses its viscosity and its ability to keep impurities trapped in suspension, hydraulic oil, like engine oil, can be deceiving. This is because the act of keeping impurities suspended in suspension helps protect all moving parts of the system. Hydraulic systems are useful to accurate tolerances, and the majority of hydraulic problems may track back to polluted or improper hydraulic oil. Hydraulic systems are helpful to exact tolerances.
One of the many important functions of hydraulic oil is that it removes moisture from the system by absorbing it and keeping it away from the hydraulic components. In a hydraulic system that is hermetically sealed and continuously refilled with oil, rust may not appear to be an issue; nonetheless, it is. Make the mistake of presuming that the hydraulic oil is in good condition merely because it seems to be in good condition. When hydraulic oil becomes cloudy, it is well past the time when it should have been replaced. And has lost a significant amount of its capacity to properly protect the components that make up your hydraulic system. Even though it varies from unit to unit, hydraulic oil should be changed every 2,000 to 4,000 hours, as recommended by the majority of equipment manufacturers. Your operator’s manual will provide you with specific information regarding the maintenance schedule as well as the oil requirements.
- Maintain a record of everything.
Despite the fact that it is the most arduous and time-consuming of all chores, maintaining service records and keeping track of bills for repairs, oil changes, and filters must be done. It is possible that in the future it will produce information that will be helpful for evaluating the service life of your equipment. In the end, every piece of machinery will have to be replaced because it will have worn out its usefulness. In addition, if you maintain accurate records, you will have a benchmark to use when determining how well the equipment is operating. And then make an educated decision about whether you want to continue purchasing products from the same manufacturer or switch to a different brand.
It is to your advantage to have accurate service paperwork to present to your dealer in the event that a problem develops with your vehicle. Maintaining accurate records will show both your dealer and the manufacturer that you value the equipment that you have invested in. This is a very significant consideration when dealing with warranty claims. This idea is critical to adhere to regardless of whether you operate a small-excavator fleet or a single unit.
