This John Deere 490 Excavator Problems and Solutions article will show you some common problems with these machines, as well as some suggestions on how they can be rectified.
John Deere 490 Excavator The throttle is intermittent
If your John Deere 490 Excavator The throttle is intermittent or otherwise not working properly, you’re in need of a new throttle cable. On top of that, you probably want to replace both the right and left hand side cables to prevent issues in the future.
The throttle cable is what allows you to control the speed of your excavator. If it isn’t working properly, you’ll be putting yourself and those around you at risk for injury.
While replacing a throttle cable is certainly not an easy task, it’s one that can be completed without too much trouble. It’s also relatively inexpensive and will save you money from having to bring in professional help.
This video tutorial shows how to install a new throttle cable on your John Deere 490 Excavator.
John Deere 490 Excavator Engine overheating
The John Deere 490 Excavator is a great piece of equipment. However, in the case that you are experiencing an engine overheating situation there is a very specific cause and solution. The radiator fan is located behind the engine compartment doors on the left side of the unit.
There is an air intake located on the bottom left of the door that brings air from outside of the machine directly into the radiator which cools down your engine with fresh air.
If you ever notice your fan running but your engine overheating, this is a clear sign that there is something blocking or restricting airflow to your radiator. After removing all debris/obstructions to airflow we recommend installing a pre-cleaner to catch debris before it enters your machine.
This will keep your fan working at peak efficiency and keep your John Deere 490 Excavator performing its best!
John Deere 490 Excavator Fuel Leaks
The John Deere 490 excavator will leak fuel from the fuel cap and the fuel tank, resulting in wasted fuel and a fire hazard. The cause of this is that the O-ring inside the fuel cap is worn out and needs to be replaced.
The first step is to remove the old O-ring from the fuel cap, which can be done with a small screwdriver or other similar tool.
Next, lubricate the new O-ring with grease and place it into position on the fuel cap.
Finally, insert a new gasket into position on top of the O-ring, replacing it if necessary.
The last step of this process is to replace any worn out parts in your vehicle that may be causing these problems so they don’t happen again.
John Deere 490 Excavator Charging System Troubleshooting
The charging system is responsible for regulating the power coming from the engine to recharge the battery and operate any electrical components. The alternator sends power to the electrical system while the engine is running, and also sends power to recharge the battery when it’s needed.
If you have a John Deere 490 Excavator, you may have experienced problems with your charging system. If so, here are some troubleshooting tips to help you find a solution:
When you start your engine, check the voltmeter reading. It should read about 13 volts or slightly more. If it’s lower than that or jumping around, there’s a problem with your alternator or its connections. Check all of your main wiring connections and fuses between the alternator and starter relay.
If these look good, check for bad diodes in the alternator rectifier assembly by measuring resistance between both terminals on each diode across the DC output terminals of the alternator. If one of them has low or no resistance in one direction, but high resistance in the other direction, it’s faulty and needs to be replaced.
John Deere 490 Excavator Wiring and electrical problems
Hi all, I have a new to me John Deere 490 excavator that I am having some major electrical issues with. When I bought it it had an intermittent problem that would cause the machine to just die. You could unhitch the battery ground and then put it back on and it would start right back up so I thought there must be a bad connection somewhere.
I replaced the battery cables, tested the alternator and made sure everything was good there. The machine still broke down after about an hour of running. It would blow the 15 amp fuse for the main starter relay when it died. So I decided to replace all of the wiring harnesses in the machine to try and fix this issue. Still having problems though. It will run for about an hour then die again randomly, sometimes 20 minutes after starting up sometimes an hour or so after starting up.
I have a meter that I use to check each wire in the harnesses while they are plugged into the different components to make sure they are getting power and not shorting out on anything metal or anything else like that but I am at my wits end with this thing!
John Deere 490 Excavator Hydraulics issues
After I changed the hydraulic oil on my John Deere 490 excavator it would not raise or lower. The arm moved to the left and right with no problems.
The hydraulics had been making a lot of noise and was not performing well before I changed the oil. I was hoping that would solve the problem but all I accomplished was getting the machine running worse than before.
I searched the web for any information about this problem, but did not find anything that helped me. There is plenty of information on how to change the hydraulic oil on a John Deere 490 excavator but not much else.
After working on this issue for several weeks, during my free time, I finally found what the problem was. In my case it was a dirty hydraulic filter. The hydraulic pump draws oil from the hydraulic reservoir through a filter and then sends it to the rest of the system through another filter. Over time these filters get very dirty and need to be replaced.
When you change the oil on your John Deere 490 excavator make sure you change both filters and clean off as much dirt as possible from them before putting them in your machine.
John Deere 490 Excavator Bucket ram lost pressure
Bucket Ram is slow to extend and retract.
1. Check the condition of the oil in the breaker reservoir. If it is milky, change out the oil and test in the breakers. If it passes, clean out the bucket cylinders and service with new hydraulic fluid.
2. Check that the return line from each cylinder is not restricted or clogged.
3. Check for leaks in seals on hoses or fittings that may allow air into system.
4. Check for loose connections at the hose fittings that may allow air into system.
5. Test for proper operation of check valves (one on each side of truck). The valves are located in each supply line at a point just before hose enters bucket cylinder.
6. Check for bent rods on bucket cylinders that could cause binding or other mechanical problems inside bucket cylinder housing or linkage area (arms and pivot points).
The John Deere 490 Excavator is a surprisingly affordable option for serious hobbyists or aspiring professional contractors. With an engine powerful enough to handle jobs twice its weight, and a fully functional hydraulic system for hauling more material than most other options on the market, the John Deere 490 Excavator is nothing to sniff at. If you’re willing to spend the money, this machine will handle most jobs that come your way without a hitch.
