Has anyone had problems with the fuel filters on volvo excavators? We can only go about 250 hrs before they have to be changed. You will be working and have about 5 minutes of warning, machine will loose power, then it will completly cut off leaving the machine stranded in all types of places. will not crank until the filters have been replaced. Other than that it has been a great machine!
At MCM we had this problem too. The 460s were not too bad about it. But the 700 was bad. Dead on at 250 hours it would do the same thing your talking about. Our Cat 320Cls and 320Clus were just as bad about fuel filters.
Surely that would have more to do with fuel quality than the machine?? What ambient temperatures is this occuring at??.
I work at a Volvo dealer and I have never heard of that one before.
I would agree with that. Fuel filters are much more efficient on tier 3 engines with some down to 2 micron to ensure that the fine tolerances in the injection system are protected. Also an important point... if you are in the habit of filling fuel filters prior to installation make sure the fuel is clean and you fill the filter from the outside (unfiltered side).
It's not the fuel b/c we have no other problems we we using it in the other equipment we have. we get 500- 600 hrs out of them We work in temps ranging from 20- 100 degrees F. Nothing drastic.
filters we have the same problem on a Friends farm he has three fendt tractors ,one is common rail and needs filters changing 250- 300 hours the others not common rail go to 500 no problem ,they all use the same diesel,but different types of filter hope this helps cheers graham
I'm sorry to disturb you in this topic, but as it's speak about problem's on Volvo excavator :beatsme On one machine the engine doesn't stop even we turn the key on off position , did anyone have an idea about that or have the same trouble in the past ? :notworthy
Alfapillar: check your stop magnet. Has been a known problem on the c-model wheelloaders. May be the same here. They moved it on later models, and added a wire to have it out of the engine vibration.(moved away from the engine.) On the exc: Is there a 250h change on the filters? If it is, i bet the onboard computer turns the engine down if u don't change filters in time..... The tier 3 engines are very dependent on clean fuel to comply to emission standards. Computers controll everything on machines today.
No, the book said it should go about 500 hours, last change i think we only got about 200 hrs out of it
OK... This is a little nut to crack. There might be a wrong adjustment on the sensor that measure the pressure/wacume over the filter. Or u got very bad fuel with much particles/things that clog up the filter. Haven't been into this problem though....
Chris, Does the Volvo have a drain on the prefilter? If so, crack it a few times a week. The other thing I did with the Cat 320s was crack the drain valve on the bottom of the fuel tank every morning. Usually when it gets cold out. You wouldnt think this would be a big deal until you do it. A lot of the time the stuff coming out would be brown, not pink/red like offroad fuel is. But you have to do the drain tricks first thing in the morning. Before start up. This gets everything in the system that has settled out overnight. Josh
Other than that how do you like the machine? I've heard good things about Volvo
Like you said other than that it is one outstanding machine, very nice cab loaded with all types of options. Its has more power than many of the other brands of equipment, compare to a deere the volvo is twice as fast. Plus its easy on the operator!! I enjoy operating it.
I suspect your problem is a combination of things. Firstly, as mentioned, modern fuel injections systems are very suseptible to particulate damage so the filtration is becoming more critical. Secondly, due to the nature of the injection systems and the very high pressures more fuel is recirculated back to the tank for cooling. This basically means you are filtering the fuel more. The other big factor is fuel quality control is not what it used to be....well...more to say it is manufactured to the mimimum standard whereas in days gone by they did the very best they could, as a matter of providing the highest quality they could. Fuel being shipped down under is prepared for a particular climate/month. If the fuel is not used in that temperature range or the weather turns cold then you will have problems. I have personally pushed a number of brown sausages out of the fuel lines of loaders in cold weather cause they just wont start. Once upon a time fuel was manufactured for us to be good at anytime of the year.
Dirtman, when writing the book the manufacturer selects the recommended service interval on a global basis as they don't really have any control over local fuel quality. It could be that you (or Volvo) need an additional pre-filter to allow the scheduled maintenance intervals to be realised. I would talk to your dealer to see what they think and whether some pre-filter may be needed to allow you to work without those interruptions.
It has 2 filters on it. The big metal one that screws on beside the fuel take and then the paper filter that goes on the motor. must be volvo's setup because a buddy of ours has two volvos about the same age of ours and they have the exact same problem. Both of us have different fuel suppliers too. Has anyone else noticed it, but within the last couple of months the off road fuel has gone from a dark red color to a more pinkish red color? Anyone know why.
We're currently running six Volvo excavators and we have not experienced this problem.
Does it have anything to do with that low sulfur off road diesel crap? I know when we started running the low sulfur on road in the trucks we lost a mile or so per gallon.
This has a smell more of a factory problem than just plugged fuel filters. Fuel filters don't just plug all at once and right on schedule. They don't kill the motor without a fair amount of time slowing down the engine speed first. The salesman should be called into the office and put on a hot plate until the problem is resolved. I would be looking for fault codes in a display panel somewhere. If there are supposedly safety systems that shut down the engine when the filter does what it's supposed to do, then I would refuse to work underneath it. I've seen many situations where an engine shutdown will put people in plenty of danger. Setting man holes comes to mind but I'm sure others here will think of other times. As to the comment on fuel quality I don't buy into that in any way. The USA has gone to low sulfer diesel which has an inherent need to produce higher quality fuel. Very shortly we will be using ultralow sulfer diesel which has to be even better. If you are getting dirt or water in your fuel, your supplier should be getting cooked on the same burner as the Volvo salesman.
John, Western Australia has been on Low Sulphur since 2000. The issue is not dirt or water in the fuel...its a case of manufacture quality being good enough for the new generation engines. The political spin on low sulphur said things like "cleaner" and higher quality" ... well, aside from the reduction in sulphur and various additives for lubricity nothing has changed...its as simple as that. Please have a read of this: http://www.fuelsavingsite.com/articles/diesel_fuel_quality.php I've no doubt that this guy is spin doctoring to some extent because of his "vested interest but he does put it in a nut shell. Not 12 years ago when I was handling a lot of fuel the shelf life of diesel was measured in years...up to 100 years for NATO spec F76....now we are talking months or weeks.
I agree with u squizzy, diesel fuel quality has not risen over the years. Here by us we are using military F-34 fuel on everything that moves. And thats kerosene + some additives. Sometimes we are unlucky and go empty and have to get diesel in our tanks, when not close to a military gas station. Fill your tank 2 -3 times and the diesel leaves all kind of **** inside the tanks, lines and system. When we then add F-34, that is thinner and a real cleaner for the system, Hell brakes loose. Filters then get clogged and we have to go to the workshop and flush the whole system. It's realy unbeliavely how much polution its in the diesel fuel. A fuel system runned on F-34 is absolutely steel clean inside, the fuel is like water and u can se the bottom of the tank through the fuel. Try that on diesel.... F-34 has a lot of other drawbacks but that's a different discussion... I would first take som samples of the fuel and see how the quality is on it. Then take a talk with the dealer regarding the problem.
power boost on ew170 volvo excavator Theres no power at the thumb button on joy stick or on the rocker switch from hammer/boost. Also the lift man with barbells on instrument panel doesnt light up during prestart check. Checked all the fuses and looked for relays behind the seat. We have no electrical books on this for me to go by. Mechanic said that it wasnt important but it runs the hammer on the same control button. Any information i could get to help me find the solution to this problem would be greatly appericaited.
look on the right side of the cab. there should be a row of switches, look for the one that has a grapple/ hammer picture on it ( i will look tomorrow but i think that is whats on it) take the switch and move it back and forth from the thumb to hammer position. On our if you accidentally hit that button while the machine is running the thumb will completly drop all the way down, and wont go back up. you have to cut the machine off, wiggle the switch while the machine is off and leave it in the thumb postion before cutting it back on, then it should work. Then the light of the man with the weights will light back up on the control screen Hope that helps.
Welcome to HEF tw 692000! :drinkup
yes i know of that switch on my machine it is a pic of man with barbells /hammer , the trash thumb is on a pedal on the floor.I checked this switch with a test light no electrial power is there or on the joystick push button that activates the power boost/hammer. The man with weights on the control screen will not light up @ all even during prestart when it goes through its start up test the man quit lighting up like it did when the boost worked! thank you 4 all the information i'll try what you said and see if that works !
thank you!!!!:drinkup cheers:usa
I have a mitsubishi engine. When I rev. it up it dies. Would it be the fuel filters
Welcome to Heavy Equipment Forums loneranger16125! :drinkup
I have a 160 and had the same problem for the first 1000 hrs. after that is got better for some reason.
Welcome to Heavy Equipment Forums MDD! :drinkup
thanks Countryboy, I joined a while back, but havnt posted till now.
I'll help you out and turn your second post into a thread in the Excavator Forum. It will be called "Volvo Turn-table seal problem".
I had the same problem with my loader and was told to use that lucas fuel conditioner, it worked it still happens but very rarely plus it feels like it has more power but not sure about that.
Just wondering if you have noticed any discolouration of the fuel. becouse there have been cases of a bacteria that grows in the fuel, and it turns it almost black, but what it does is coagulates in the filter paper of the filters and totally restricts the flow, it starts with a batch of contaminated fuel and just keeps growing.. worth a look?
240 does this to Yes this has happend to our 240 Volvo hoe also,it gave us a code which the dealer said was low fuel pressure,we changed filters twice and the way it went?I thought it was bad fuel but none of the other machines did this?
Is there a screen in the fuel inlet at the pum some exc. have a banjo fitting at the transfer pump take it out and see if screen is plugged.
