7 Most Common Problems with Kubota RTV X1140

The X1140 is well-built and lacks the weak plastic components that are common on today’s UTVs.

A Kubota diesel engine with a displacement of 1123cc powers the show. Motorcycles with greater engines are available. At 3000rpm, the maximum output is estimated to be 24hp (18kW).

A hydrostatic gearbox transmits this amount of torque to the wheels. Front diff is a limited-slip unit, while the rear diff has a diff lock that is controlled manually by a foot control on the driver’s left side. We like this since the operator selects when and for how long to utilize the diff lock.

However, if you are a heavy driver, certain elements of the car may give you a headache. Problems might also arise as the ride grows stale. Today, I’ll go through some of the most typical issues with the Kubota RTV X1140.

Common Problems of the Kubota RTV X1140:

1. Loose Drive Shaft

If you notice that your RTV is having this problem, take it to the dealer and have a replacement U-joint fitted. Depending on the age of the RTV, the dealership may be able to repair it at a reduced cost.

An issue with the driveshaft might also manifest itself in unusual sounds. The driveshaft’s ability to rotate appropriately can be hampered if the bushing or bearing that supports the driveshaft or the driveshaft U-joints wear out or break.

At low speeds, a squeaking U-joint in need of lubrication might also make a squeaking noise. A defective CV joint can be identified by clicking or knocking sounds. These kinds of noises indicate that the car needs to be repaired as soon as feasible.

2. Brake Issues

Customers have complained about the Kubota RTV braking mechanism on several occasions. Even when the brakes are applied, the car tends to go ahead. The problem is most prevalent while braking quickly, but it seldom happens under typical braking circumstances.

The problem is linked to the speed lever assembly, however, following further investigation; no particular cause has been identified.

If the braking system leaks, you’ll have a hard time getting the pressure up to where it needs to be. It doesn’t have to be a large leak for you to notice that anything is wrong.

You should examine the brake lines from the master cylinder to the brake calipers once again. Drag a clean piece of paper along the brake line to make it simpler to pick up any leaking brake fluid.

3. Transmission Problems

The transmission can develop this problem if you use mixed transmission fluids instead of the prescribed Super UDT. If the problem remains after using the prescribed transmission fluid, the problem might be the relieving pressure in the port block.

If one of the clutches fails to engage, your ATV may not be able to drive forward. While in gear and applying throttle, listen for any unusual or strange noises coming from the belt housing region.

You’ll need to open the belt shield and look at how the clutches work to learn more. When the motor is running, take your fingers and any loose items away from the clutches.

4. Windshield Issues

According to Compactor Tractor Review, RTV owners are complaining about the difficulties of putting windshields on Kubota-s with plastic roofs.

Although there have been no major complaints concerning windshield installation on metal roofs, your owner’s handbook will instruct you on how to properly install both.

When fitting a windshield into a plastic roof, Kubota recommends leaving the interior roof mounting bolts removed. The bolts on the front roof mounting brackets are the only ones that must be kept unfastened during installation. You may now reinstall the plastic roof after the shield has been placed.

5. Carburetor Problem

I would first examine the carburetor. All you have to do now is spray some carb cleaning or ether down the carb and see if your engine will start. Alternatively, Pouring gas in CARB to start. (Pouring gasoline into the carburetor is dangerous and should not be done unless there is no other option for starting your car)

If it does start, but then dies immediately, we now know there’s an issue supplying gasoline to the carburetor. We know this because the engine starts when the carb has fuel. Check to see whether gasoline is going to the carburetor right now.

If it still won’t start, you could have a gasoline delivery problem from the carburetor to the engine. That indicates that the issue is further down the road. If that’s the case, there might be a compression issue.

6. Fuel Injector

If you suspect a problem with your fuel injectors, I’d consider cleaning them first before investing in new ones, since they may be rather costly. You must first disconnect the fuel lines from the fuel injectors.

You may also totally remove the fuel injectors and immerse them in fuel injector cleaning. You are free to use any carb cleaner or fuel injector cleaner you like.

You can use another way if you don’t want to remove the fuel injectors. You’ll still need to disconnect the gasoline lines and let all of the gas out. The fuel line will then be filled with fuel injector cleaning, and the fuel lines will be reconnected.

7. Fuel Pump

I’d recommend blowing air into the fuel pump to ensure that petrol can flow freely through it. However, if you have a vacuum pump, you won’t be able to do so. Some diaphragms might be harmed in there.

Pull the vacuum connection to the fuel pump off and rev the engine to ensure your vacuum-operated fuel pump is operating properly. A significant quantity of suction should be felt at the carb’s mouth.

To make sure you’re getting gasoline to the carburetor, clean the fuel line and replace the fuel filter if you can. Examine the fuel pump for signs of wear and cracks in the hoses.

Your carb will not obtain any gasoline if there is no suction in the pipe. A fracture in the vacuum fuel lines or a malfunctioning fuel pump is the most likely cause.

We use a Kubota out at our land. Ours has been very solid the last 5 years, but unfortunately, just recently it developed some sort of problem where you can still hear a clicking noise from the engine area when you shut it down and the only way to get it to stop is to unplug the battery. So we are about to send it in and have it serviced.”

 I have an older 1140. It has been a good machine for what I use it for on my ranch. Not fast at all but I don’t care about that. The one problem that I have is that the radiator is placed so that the dust from the front tire kicks up right into the radiator and caused the machine to overheat. The new machines have the radiator up front to correct this problem.”
