The Most Common John Deere 12.5 Liter Engine Problems
- Engine Oil Leaking Problem
Most of the users of John Deere faced the leaking issue in the 112.5-liter engine.
The users mentioned that the engine oil leaks and sometimes mixes with the coolant. This problem is caused only if the seals or engine tubes are leaking.
Therefore, you can resolve this problem by installing new seals and tubes in the engine.
However, installing new seals and tubes will cost a lot. Thus, to save your money, claim the warranty of your tractor.
- Water Pump Problem
On the other hand, the users of John Deere also faced a water pump leaking problem in the 112.5-liter engine.
However, this problem should be fixed as soon as possible. If you do not replace the water pump on time, the water will start mixing with the engine oil and can cause serious issues in the tractor.
- Engine Stalling Problem
Aside from the water pump problem, the users also experienced the engine stalling problem in the 112.5-liter engines of John Deere.
This problem is caused due to negligence in the maintenance of the tractor.
Therefore, addressing the reason behind this problem is necessary, and all that you have to do is to inspect the following things
- Oil Level
- Air Filter
- Fuel Type
- Oil Type
- Fuel Pump
- Fuel Injectors
- Fuel Filter
Thus, to fix the engine stalling issue, these are some reasons that need to be inspected.
Therefore, start the inspection from the oil level, and top it up if it is lower than the specified level. After inspecting the oil level, you need to check the air filter.
It is because if the air filter is blocked, then you will face the engine stalling issue.
If the air filter is the case, then replace it from the nearest service centre.
On the other hand, if the air filter is not the case and you are still facing this issue, then the fuel type can be the reason that is causing this problem.
Therefore, if this is the case, drain the fuel from the tank and fill it with the recommended one for your tractor.
Moreover, you can also face this issue if the oil type is wrong. Therefore, always use the correct type of oil recommended by the company.
After you are done inspecting, the oil type inspects the fuel pump and the fuel filter.
It is because if there is any blockage in them, then the tractor’s engine will stall. If this is the case, then replace them from the service centre of John Deere to fix this issue.
Aside from the fuel filter and the fuel pump, you can also run into the engine stalling issue if the timing of the fuel injectors is unadjusted.
Thus, you can resolve this by adjusting the timing of the injectors.
- Engine Performance Problem
Most John Deere users also faced performance issues with the 12.5-litre engine. This problem cannot be ignored because 12.5-litre engines are powerful.
Therefore, you need to replace the fuel filter and the tractor’s air filter to fix this issue. Moreover, you can also run into this problem if the fuel pump is defective.
If the fuel pump contributes to this problem, then all that has to be done is to replace it from the authorized service centre of John Deere.
However, replacing it will cost a lot. Therefore, claim the warranty of your tractor to save money.
