Kubota L4701 Problems And Their Solutions
Here is a list of Kubota L4701 Problems and how to fix them. Which are as follows:
(1) Accessories problems
(2) Engine problems
(3) Motor problems
(4) HST problems
(5) Steering problems
(6) Diesel problems
(1) Problem 1: Kubota L4701 Accessories problems
A customer purchased a Kubota L4701 with either a backhoe. There was a problem, and the diesel wouldn’t start. And it took a long time to start.
So, the owner must examine the starter and, if necessary, replace it to fix the problem. Fuel can get stuck in the fuel line. Wash it out and flush it. The fuel filter could have dirt in it, so change it.
Rings on pistons can break. Replace them with a new collection of rings. The tank vent could get restricted.
If a gear and ball bearing fails, the front axle that does the driving can often crack while it’s in use. You must also check this same injection nozzle and the injection pump.
Right away, the lockable differential can break. The diaphragm can break, or the friction clutch’s disks can wear out. If white smoke comes from the exhaust pipe, the piston rings need to be changed immediately.
(2) Problem 2: Kubota L4701 Engine problems
The Kubota L4701’s engine can lose power. This can happen if there’s too much oil in the machine. Some owners tend to put in more oil than they need to. But it would help if you never did this.
Uneven fuel injection is another thing that could be wrong with the engine. The pump that injects fuel can get clogged. Change the pump that injects fuel. This can also occur if the valve is too tight or too loose.
Another customer said that his tractor’s engine had stopped running.
The engine can sometimes stop working when the oil is low. It would help if you used 15W-40, 10W-30, or SAE30 oil for the machine. So, when the fuel is old or dirty, it clogs up the fuel supply pump.
When it gets too cold, the headlight with the code P3001 may appear on the screen. The code means that the vehicle needs to be regenerated.
When the temperature drops below 20 degrees Fahrenheit, this happens, and you have to halt the tractor. If you require a forced regen, only the dealer or one service manager can do it.
(3) Problem 3: Kubota L4701 Motor problems
One Kubota L4701 can get too hot in the motor. It could happen if the coolant level is low. So, users must fill the radiator with the right amount of liquid.
This same radiator gets dirty from time to time. So, it needs to be cleaned. If too many things are on the engine, shift to the lower position or take some things off.
This problem can be caused by a loose or broken fan belt. When it’s time, replace the fan belt. Check this same belt tensioner as well.
(4) Problem 4: Kubota L4701 HST problems
Some problems with the hydrostatic transmission can be seen in this L4701. The shifting is rough because of the transmission.
There could be more than one reason. But one of the primary reasons is that the clutch pedal isn’t pressed down when shifting gears. So, the driver must do what the directions say.
(5) Problem 5: Kubota L4701 Steering problems
The buyers need to understand why the steering wheel is free to spin. One reason could be that there needs to be hydraulic oil in the tank. You have to put oil in.
There can be a lot of wear on the steering cylinder. You might have to make a new one. The steering pump that doesn’t work right can also be a cause—putting in a new pump. The steering wheel only sometimes works well.
The airlock inside the steering system can cause this problem. Get rid of the air in the system. There can also be air leaks in suction lines.
Air can also be made in the hydraulic system. The air needs to be let out of the system. A small light in the tank shows if there is hydraulic oil. Fill the tank up. If the hydraulic steering cylinder breaks, it can be hard to turn the vehicle. So, make something else.
The problem can also be caused by uneven tire pressure. Change the force. There could also be a leaky hydraulic connection. Get rid of the issue.
The power steering pump can get broken. Get the pump fixed. This same power steering can wear out over time. Change it.
Steering problems can also be caused by lousy valve timing, too much or too little compression, worn cylinder bores, valves, and leaky seats.
(6) Problem 6: Kubota L4701 Diesel problems
A customer talked about how he used this L sequence loader. His Kubota L4701 launcher has been acting up as of late. The diesel didn’t rotate.
The problem could be that the wrong kind or fuel rating was used. Ensure that the API rating of your oil is at least CF.
Kubota recommends petroleum with an API rank of CF as well as higher. If your synthetic oil meets those requirements, you can use it in Kubota engines.
Another reason could be that the fuel pump drive is broken. You need to look at it and fix it if it needs to be. When the fuel injection pump timing was wrong, the fuel line wouldn’t get the fuel in time. This needs to be changed.
The drive shaft of the fuel pump can break. Water could get into the fuel, or the energy would be too heavy if the temperature is too low.
Kubota l4701 Review
An L4701 from Kubota is a valuable machine. It has a durable Kubota Diesel engine that is strong and works well. The L4701 comes with 4WD and hydrostatic transmission, which makes it easy to drive on any surface.
The L4701 also has Kubota’s excellent Dynamic Hydro Transmission (VHT), which lets the driver control the speed indefinitely and switch speeds on the fly. The L4701 is a beautiful device for anyone who wants a reliable tractor to do many different jobs.
Code P3001
Your Kubota L4701 may have given you a code error P3001 when it was freezing.
Don’t worry about this code; it just means that the Kubota diesel needs to change its settings to produce higher temperatures. This is called “ReGen.”
When the heat is below 20°F, this usually happens. If you need to compel ReGen, only your Kubota vendor or an authorized service can do it.
Kubota L4701 Hydrostatic Transmission Problems
A few people had trouble with the L4701’s hydrostatic transmission. It appears that the shift is rough because of problems with the transmission.
A rough shift usually happens because the driver doesn’t push down on the clutch pedal. In this case, this could help to look at the workshop handbook and do what it says.
Kubota L4701 Overheating Problems
The Kubota engine usually stays cool, but it can if you don’t take care.
Most of the time, the Kubota engine gets too hot because of the radiator. For example, if it needs more coolant, you must add the right amount.
It’s also possible that your heater is dirty and has built up dirt and dust inside. To keep your motor healthy and running, it’s essential to do regular maintenance. If you think your engine is too heavy, you should lighten the load and shift to a lower gear.
If the problem isn’t with the radiator, it’s generally the fan belt. The belt should be tight enough and in the right place.
The fan belt causing the engine to get too hot is a more frequent issue than you might think. Even the John Deere 1025r tractor has the same problem.
Kubota L4701 Loader Problems
A Kubota BX2380 has the same problem, so it appears to be a frequent issue with Kubota tractors.
When it’s time to put this same loader back on, Kubota owners may have noticed that one side is perfectly lined up, whereas the other pops out.
The only way to avoid this problem is to mount this same loader on level ground, which usually means doing it in your garage.
But if everything is done and you’re still having trouble, don’t worry. All it takes is a bit of manual work (as well as patience) to get it working again.
As you may know, the loader’s bottom left cylinders are linked together. This means that side is forced to be higher than the other.
One way to resolve the loader issue is to try to level the coils by changing how far they extend.
Kubota L4701 problems: are they a deal-breaker?
These problems aren’t bad enough to make me not want to buy them. Most of these problems can happen with any tractor model and are easy to fix with some care and maintenance.
If the tractor is still under warranty, you should talk to your service manager about significant engine problems.
But the problems in this article could be fixed without the help of a professional. You can figure out the problem on your own to save money.
The golden rule is that you should only do something if you know what you’re doing. So, if that’s the case, give one’s machine to a pro.
