Check 1994 john deere 490e excavator oil level and pressure
HELP! I just inherited a John Deere 490e excavator. It has been on the property for about 5 years. It has about 5400 hours on it. I have no idea if it has ever had an oil change or not, and hardly ever do I find any maintenance records from previous owners.
I have read the operators manual, but it does not give very good instructions on how to check the engine oil level or pressure, as well as checking the coolant level and pressure.
Can someone please give me simple step by step instructions on how to check these things? I am new to this equipment, and I don’t want to run it without knowing what the levels are at.
1994 john deere 490e excavator Air filter is clean
Air filter is clean with no leaks. The air inlet hose has a small hole. I have not figured out where the hole is coming from. It will be fixed when I figure it out. I am selling a 1994 John Deere 490e excavator. It needs work but is a good machine. The engine is good and it runs and drives. The under carriage has been replaced in the past and has 95% life left on it. It has low hours for its age of around 14000 hours.
All hydraulic cylinders are tight but one cylinder on the stick has developed a leak which could be an easy fix but I just don’t have the time to get into it right now because we are busy working with other machines. The engine blows some oil at the rear seal and there are a couple of other seals that need to be replaced also on the engine as well as oil leaks at the front and rear drive shafts but they are not bad leaks at all and won’t hurt anything until they can be fixed later down the road.. There is also one hydraulic line that needs to be replaced because of wear and tear that comes from use over time.
Check 1994 john deere 490e excavator fuel level
The 1994 John Deere 490E excavator is a large piece of machinery, and fuel can be an expensive commodity. Checking the fuel level on this machine is important to ensure it has enough fuel to carry out its intended function. The fuel tank holds more than 65 gallons, so running it dry could be costly.
The process for checking the fuel level on this machine is a simple one, requiring only a few minutes of your time.
Step 1:Turn off the engine and exit the cab of the John Deere 490E excavator.
Step 2:Step over to the left side of the rear hood and locate the side inspection door. Open this door by lifting up on the handle until it locks into place.
Step 3:Locate the dipstick attached to the fuel tank, which sits just inside this inspection door. Remove the dipstick from its housing and clean it with a rag or paper towel to remove any debris or residue that may be present. Once clean, reinsert it into its housing, but do not allow it to touch the bottom of the hole as you do so. Remove and check it again for residue that may have come up with it when you pulled it out of its housing.
Check 1994 john deere 490e excavator hydraulic oil level
Unscrew the oil fill cap, which is a small metal cap located on top of the hydraulic tank. Pull the dipstick out of the hydraulic tank, and wipe it off with a clean rag. Push the dipstick into the hydraulic tank as far as it will go, and pull it out again. Look at the end of the oil stick to read your fluid level. The oil level should be between “full” and “add.”
If you need to add oil, then remove the oil fill cap and pour in a small amount of hydraulic fluid. Reinsert the dipstick and check your fluid level again. Continue adding fluid until you have reached a full level on your oil stick.

We have not been able to fix a problem with a 1994 John Deere 490e excavator losing power so far
We have not been able to fix a problem with a 1994 John Deere 490e excavator losing power so far. The machine starts and runs fine in cold weather but when it warms up the engine will start to gradually lose power and eventually die.
We have replaced the fuel filter, air filter, oil and oil filter, cleaned the fuel tank and fuel pump screen, checked the fuel pressure at the injectors and even replaced the ECU unit but nothing has fixed the problem.
I think we are getting to two possibilities: 1) We may have somehow damaged one of the injectors by disconnecting them or 2) There is a problem with some kind of sensor or computer control unit that won’t let the machine run properly once it warms up.
Has anyone else had this kind of problem with this machine? I am at my wit’s end.
