Kubota SVL65 2 Problems: Here Are the Issues and Fixes

Kubota is a popular brand when it comes to diesel engines under 100 hp, and is also a well-known innovator in the fields of compact tractors and diesel ride-on lawnmowers. One of its key entries in the compact track loader (CTL) segment of the market is the SVL65 2.

The Kubota SVL65 2 seeks to elevate itself from the competition by its light weight that allows better maneuverability and advanced hydraulic system for various heavy work applications.

Its packaging certainly offers an irresistible choice for enterprising individuals or companies but there are a few problems that you may want to know about it first before purchasing one or if you are a new owner of the unit.

What You'll See Here

The Kubota SVL65 2 is an interesting CTL. However, based on the common complaints about it, here are some problems that it is prone of:

• Hard Starts
• Engine Stalling
• DPF Light Activation
• Overheating
• Hydraulic System Failure

Most Common Problems Found in the Kubota SVL65 2 and Their Possible Solutions

The Kubota SVL65 2 is packaged to be a tough piece of machinery. It is also known for its stability, power, and durability. There are, however, several problems that you should pay attention to when operating it, these include:

1. Hard Starts

Hard starting in the Kubota SVL65 2 can be caused by several factors. The most common of them include fuel getting too viscous, oil viscosity getting too high in winter, the presence of oil or water in the system, or a blown fuse.

Fuel getting too viscous is usually caused by cold weather. The solution is to use a lower-viscosity fuel or add a fuel conditioner to the tank. Oil viscosity getting too high in winter can also cause hard starting. The solution is to use a thinner oil or change the oil filter.

The presence of oil or water in the system can also cause hard starting. The solution is to have the system flushed and refilled with fresh fluids. It should also be bled if its air mixture is above the recommended amounts. Likewise, a blown fuse can cause hard starting. The solution is to replace the fuse.

Hard starting can also be caused by a number of other factors within the ignition or charging system of the vehicle. If the problem persists, it is best to consult a qualified technician for further diagnosis and possible repairs.

2. Engine Stalling

If the Kubota SVL65 2 engine frequently stalls, there are a few things you can check to try and diagnose the problem. Although many things can cause this, the most common in this product are clogged air filter and the fuel system needing purging due to contamination.

First, check the air filter for any visual indications of clogging. If it's still relatively new or it still shows signs of functionality, you may get away by simply cleaning it. However, if it's already worn or due for a replacement in accordance with its manufacturer's recommendations, replace it as needed.

Next, purge the fuel system by running a small amount of fresh fuel through it if it displays signs of contamination. Replace any worn or damaged parts if needed. Most of the time, it's the fuel filter that needs to be changed when it comes to matters related to dirt or debris build-up in the fuel system.

For a good measure, check for any leaks in the fuel system. If you find any, repair or replace the parts causing them. Following these steps should help you get your engine up and running again.

3. DPF Light Activation

The DPF light on your Kubota SVL65 2 may turn on for a number of reasons. Your owner's manual will likely have a section dedicated to this particular light, but we'll go over the basics here.

The DPF, or diesel particulate filter, is a device that captures and stores exhaust soot in order to reduce emissions. Over time, the soot accumulates and needs to be cleaned out, and this is called regeneration. Regeneration can happen passively, through the use of heat from the engine, or actively, through the use of additives injected into the exhaust stream.

If the passive regeneration process doesn't work properly, the DPF light will come on to let you know. This could be due to several issues, including a blockage in the DPF, fuel quality problems, or an issue with the exhaust gas recirculation (EGR) system.

If you see the DPF light come on, it's important to take action right away. If the regeneration process is allowed to continue without being fixed, it could lead to damage to the DPF itself - and that could mean big bucks to repair or replace it.

There are a few things you can do if you see the DPF light come on. First, check your owner's manual to see if there are any specific instructions for your vehicle. If not, the general rule of thumb is to avoid extended idling and driving at low speeds. These can make the problem worse and make regeneration less likely to happen.

If the light doesn't go off after a day or so of driving, it's time to take your Kubota SVL65 2 to a dealer or service center for diagnosis and repair. They'll be able to help you figure out what's causing the problem and get it fixed so you can get back on the road without any more hassles.

4. Overheating

Overheating in the Kubota SVL65 2 can be due to several different issues in the cooling system. The most common cause is a faulty thermostat, which can bring the engine to overheat by not regulating the flow of coolant properly. Other potential causes include clogged radiator grille fins and contaminated coolant.

Fuel injection calibration issues can also result in the engine overheating. The lack of fuel causes some pistons to not fire at all, forcing the ones that do to work harder to compensate. Overheating results from that. One more common reason why diesel engines overheat is clogged fuel injectors, which are caused by deposits accumulating in the injector nozzle.

The best way to diagnose the cause of overheating is to take the vehicle to a qualified mechanic and have them perform a thorough inspection. They will be able to identify the root cause of the problem and recommend the best course of action. In most cases, cleaning, repairs, or parts replacements will be necessary to fix the issue.

It is important to avoid overheating the engine as it can cause serious damage. If you notice that the engine is starting to overheat, pull over and turn off the engine as soon as possible. Once the engine has cooled down, check the coolant level and add more if necessary. If the problem persists, contact a qualified mechanic for further assistance.

5. Hydraulic System Failure

The hydraulic system of the Kubota SVL65 2 compact track loader is a key component in its operation. The system uses fluid pressure to push the pistons in the cylinders, which in turn move the tracks.

The main cause of hydraulic system failure in this specific product is a clogged oil filter. This can happen if the filter gets old and starts to break down, or if there is debris in the oil. Another common cause of hydraulic system failure is a leak from hoses or joints. These leaks can be caused by wear and tear, or by damage to the hose or joint. The third most common cause of hydraulic system failure is the inability of the seat to detect an operator. This can happen if the seat is damaged or if the wires that connect the seat to the machine are damaged.

The best way to prevent hydraulic system failure is to regularly check the oil filter and replace it when it gets old. It is also important to check the hoses and joints for leaks and to replace them if they are leaking.

In addition, if the seat is no longer detecting an operator, its wiring and/or sensor should either be fixed or replaced. On the other hand, it may be possible that there's something wrong with the installation of the seat or the seat itself. If any of these is the case, have the seat installed properly, or just buy a new one that's compatible with your CTL.

Replacing the oil filter, hoses, and joints are all fairly simple tasks that can be done by anyone with basic mechanical knowledge. However, replacing the seat and fixing the electrical components linked to it may require the assistance of a qualified technician.

Conclusion

The problems with the Kubota SVL65 2 shown here are in no way a reflection of the overall performance or reliability of the CTL. There are units that have lasted years without experiencing any of the issues shown here and some have manifested issues outside of the ones discussed here. The problems identified here are only the most common subject of complaints if you tally up the concerns relating to the product.

No matter what kind of trouble you are experiencing with your Kubota SVL65 2, don't skimp on the services of a qualified mechanic so you can easily and conveniently get matters sorted out in no time.
