7 Most Common Kubota SVL75-2 Problems and How to Fix Them

The SVL75-2 is one of Kubota’s newest compact track loaders for residential and commercial projects. It’s a powerful, versatile, durable track loader designed to complete the job.

You can use this loader for various tasks like grading, hauling heavy loads, and digging trenches. Despite being a robust and reliable compact loader, this Kubota model is prone to some issues. The most common Kubota SVL75-2 problems are losing power, engine overheating, problematic starts, excessive smoke from the exhaust, fuel issues, hydraulic system problems, and electrical issues.

So, how do you fix these problems? Read on as we dissect Kubota SVL75-2 issues and effective fixes.

Kubota SVL75-2 Losing Power

The SVL75-2 compact loader can start to lose power while operating and eventually shut off. Usually, this problem occurs after using the loader for an extended period.

If your loader loses power on the field, the following might be the culprits:

  • A defective fuel injector
  • Clogged inlet elbow
  • Clogged fuel filter
  • Issues with the gears

How to fix:

A loader that loses power despite having a full tank might have issues with the inlet elbow or fuel filter. So, inspect the inlet elbow and fuel filter for clogs. If the inlet elbow has dirt or debris, disassemble and clean it.

Then, check for a dirty or clogged fuel filter and replace it. After this, drain and refill the tank with fresh, clean fuel.

If the two fixes don’t resolve your problem, check if your fuel injector is dirty or faulty. Clean any grime or debris with an effective fuel injector cleaner. If this won’t fix the problem, replace the four injectors.

The next components to check are the gears. If the 1st and 2nd gears are out of place, readjust them and tighten the gearbox cap.

Starting Issues

The Kubota SVL75-2 is prone to starting issues after operating for several years. The loader might have difficulties starting or fail to start at all.

In most cases, starting problems with your compact loader might result from the following:

  • An empty fuel tank
  • A dead battery
  • Clogged fuel filter
  • A blown-out fuse

How to fix:

Turn off the engine and let it cool before resolving these Kubota SVL75-2 problems. Then, check the fuel tank to see if it’s empty. If it’s empty, the loader won’t start. So, refill the tank with fresh fuel. Then, check for dirt or debris on the fuel filter. Replace the filter if it appears clogged or worn.

If the starting issue persists, inspect if the battery is dead and try recharging. Then check for clogged terminals or loose connections. Use battery terminal cleaner or baking soda to remove the corrosion. If the battery connections are loose, tighten them.

Lastly, check for a blown fuse and replace it if necessary.

Kubota SVL75-2 Fuel Problems

Fuel-related problems in your SVL75-2 compact loader can affect its performance. The most common causes of fuel problems in your loader include:

  • Old or contaminated fuel
  • Fuel leakage
  • Dirty fuel system

If your loader has some of these problems, you might notice signs like low engine power, rough idling, and stalling.

How to fix:

Fuel can go bad in the fuel line, especially when you store your compact loader for more than six months without running the engine. The diesel deteriorates and forms a ‘gummy’ substance. This substance clogs up the fuel filter and injector.

Moreover, dirt and debris can contaminate the fuel and clog the fuel line. Drain the old or contaminated fuel and clean the fuel system to fix these issues. If you’re storing the loader for many months, especially through winter, add diesel stabilizer to help the fuel last longer.

If the issue results from fuel leaks, inspect the leaking parts and replace them. You can also clean the fuel pump and injectors to remove any clogs. Then, replace the filter if it appears clogged.

Hydraulic System Issues

Problems with the hydraulic system of your SVL75-2 loader might result from the following:

  • Damaged or worn hoses
  • Low hydraulic fluid level
  • Damaged hydraulic pump

Kubota SVL75-2 hydraulic problems come with signs such as leaks, slow response, and noisy operations.

How to fix:

Check for a faulty hose or pump if the hydraulic fluid leaks from the system. Replace a damaged hose and hydraulic pump.

If the hydraulic system responds slowly, check the fluid level. If it’s low, add more. Contaminated fluid might also cause a slow response. If this is the cause, drain the fluid and add a fresh one. Then replace the fluid filter as it might be damaged.

Noisy operations result from the air in the hydraulic system or clogged filters. Open the bleed valve to bleed air out and replace a clogged filter.


Engine overheating is one of the most common Kubota SVL75 2 problems you might experience with your loader. When this happens, your compact loader might have a faulty water pump, clogged radiator, or low coolant level.

Operating a loader with an overheated engine can cause severe damage and costly repairs.

How to fix:

Regular maintenance can help prevent most Kubota SVL75-2 problems. If you’ve neglected routine maintenance, the overheating issue might result from a clogged radiator. Clean the dirt, mud, and debris on the radiator. If there’s stubborn grime, use a cleaning product to remove it.

Next, check for a low coolant level and top it up if necessary.

If you suspect the overheating problem results from the water pump, check if the seal is the culprit. Install it correctly or replace it if necessary. Seek advice or help from a professional to replace a faulty water pump.

Excessive Smoke From the Exhaust

Excessive smoke from your Kubota SVL75-2 might indicate a problem with the fuel system. Using contaminated or old fuel could lead to black smoke from the exhaust.

If the compact loader’s engine runs too rich, this might be another cause of smoky exhaust. This issue results from a clogged fuel filter or a faulty fuel injector.

Another cause might be an overfilled oil reservoir. Excessive oil might seep into the fuel lines and mix with the diesel fuel. When this happens, the engine runs poorly and produces excessive smoke from the exhaust.

How to fix:

If you suspect that old or contaminated fuel causes smoky exhaust, drain the fuel and add a fresh one. Then, inspect the fuel filter and replace it if it appears clogged. If there’s still black smoke, check for a faulty fuel injector and replace it if necessary.

If your loader has an overfilled oil reservoir, drain the excess oil and the contaminated fuel. You can also replace the damaged fuel lines and filter.

Electrical System Issues

Electrical issues in your SVL75-2 loader might cause starting problems and malfunctioning lights. If you experience electrical issues with your loader, check the following:

  • A dead or faulty battery
  • Corroded battery terminals
  • Loose or damaged connections
  • Blown fuses

How to fix:

The battery is the leading culprit when it comes to electrical problems. Check if low voltage is the cause and recharge the battery fully. If it fails to hold a charge, check for a faulty charging system and replace it.

If the battery won’t charge, check for corroded terminals and clean them with a battery terminal cleaner or baking soda. Replace the battery if it’s faulty.

Next, inspect the connections and replace any damaged wiring. You can also tighten any loose connections.

Lastly, check for blown fuses and replace them if necessary.
