6 Most Common Kubota L4701 Problems and Solutions
Take a look at the Kubota L4701 issues and their respective solutions outlined below:
1. Diesel issues
The customer's experience with the Kubota L4701 loader was a unique one. After noticing a breakdown, he investigated and discovered that it could be due to an incorrect type or grade of fuel. To prevent any further problems, he made sure to only use oil with an API rating of CF or higher - as recommended by Kubota.
Additionally, the customer identified another potential source of error: faulty fuel pump drive shafts which need proper adjustment and examination in order to ensure they are working correctly. He also noted that water contamination in the fuel system could be caused by low temperature or an incorrect timing of the fuel injection pump, both requiring immediate attention. With these tips from his own experiences with this series loader, customers can benefit from taking similar precautions before running into costly repairs later on down the line.
2. HST problems
This L4701 can experience some hydrostatic transmission problems, including rough shifting. There are a few potential causes of this issue, but one of the main reasons is failure to fully depress the clutch pedal when shifting. To ensure proper operation of the vehicle, it is essential that drivers follow the manufacturer’s instructions regarding how to shift with this type of transmission.
3. Engine problem
The Kubota L4701 is a powerful tractor, but if too much oil is used in the engine, it can reduce power. Overfilling the engine with oil is never recommended and could be one of the causes for an engine problem. Additionally, uneven fuel injection or incorrect valve clearance may also cause issues with the engine's performance.
Another possible cause for an engine stalling out on this model of tractor might be due to low or poor quality motor oil being used. You should always use 15W-40, 10W-30 or SAE 30 grade motor oil in order to prevent these problems from occurring. If you notice a warning light with code P3001 appearing on your screen when temperatures drop below 20F degrees then this indicates that a regen needs to take place - either by yourself if temperatures are milder or by your dealer/service manager if they're colder as this will require a forced regen procedure.
4. Steering issue
The steering wheel spinning without resistance is a common issue for buyers. Low hydraulic oil levels in the tank can be one of the reasons and it requires an addition of oil to resolve this problem. The defective steering pump or the heavily worn steering cylinder may require replacements to rectify this issue. Sometimes, airlocks in the system can cause such problems and releasing them from the system will help solve it. Uneven tire pressure adjustments, leaking connections or broken pumps are also causes that must be checked out and repaired if necessary. Lastly, improper valve timing, high or low compression, worn ear cylinder bores, valves as well as seat leakage should all be inspected to look for any signs of damage that might need repair.
5. Motor issues
Kubota's L4701 motor can overheat when the coolant level is low. To prevent this, regular maintenance and inspection of the cooling system should be performed to ensure that liquid is poured into the radiator up to its recommended level. Additionally, it’s important to clean any debris from the radiator as dirt or debris can cause blockages in air flow. Overloaded engines are also a common source of overheating; if your L4701 experiences this issue, reduce load or shift to a lower gear for relief. Finally, an old fan belt may cause overheating so inspect and replace yours as required. Check tensioner regularly for proper functioning too.
6. Accessories issues
The customer recently acquired a Kubota L4701, but experienced a breakdown with the diesel engine not starting and the starter speed being slow. To rectify these issues, it is important to check the starter and replace it if needed. It could also be that the fuel line is clogged so cleaning and flushing it may help as well as changing out any dirt in the fuel filter. Additionally, piston rings can break over time, requiring new ones to be refitted. Other areas of concern include tank venting restrictions, potential cracking of the driving front axle during operation due to gear or ball bearing failure, checking injection nozzles and pumps for damage, locking differential functions breaking down unexpectedly and examining diaphragm wear or disk worn out on friction clutch components. If white smoke appears from exhaust pipes then replacing piston rings should become an urgent priority.
