HiCustomer Welcome to JA. I am Buddy, and i will try and help you out.

If it is not time for a stationary/parked regen, you will not be able to do one without a laptop with detroit software. If it is requiring a stationary regen you can do it. Here is information card on how to do it, and what the all the warning lights mean. I hope this helps you out. If you have anymore questions, just ask.

Thanks

Thanks for your promp response. My real problem is low power. I was suspecting my low power problem was possibly due to a plugged particle filter and it needed cleaning. I just bought the truck 3,000 miles ago and have little history on it except the engine was overhauled about 35,000 ago with a notation on the repair order that it was not covered by warranty. I have a series 60 430-470 hp with a 3 axle trailer at 96-98K it will outrug the mercedes at 85K with a two axle trailer. The truck is not here but in town about 70 miles away and I will check for a regen switch Wed this week when I go there. I'm not sure I have a regen switch on the dash. No boost pressure gage so I can't read the turbo boost. Maybe I'll have to pay for a dyno.
Expert:  Buddy replied 4 years ago.
Thanks for the accept.Trucks that require regens did not start till 2007. So your truck might not have a paticurlate filter. These engines are notorious for the exhaust brake sticking and causing the truck to loose horsepower. I would inspect and make sure linkage is hooked up and that it moves. If that is good, i would verify air filter is good and replace filters. Then you could pressure test your charge air cooler and make sure it is not leaking anywhere. It should not leak no more then 5 psi in 15 seconds. Make sure all air piping clamps are tight. Let me know what you come up with, and if you have anymore questions, just ask. Also if you reply please include the last 6 of the truck vin #.

Thanks
Buddy

W27709. Earlier I said I hadn't done anything to find out the problem but I did have the air charge checked at a truck shop and they said it was OK. No specifics. I will check the clamps. Air filters are new at oil change 3,000 miles ago and I changed the fuel filters then and also just recently to be sure. Engine exhaust brake check sounds like a good idea. I see in your profile you like tindering with farmall tractors. I farm and have a IH454, a IH574, a JX65, and two big 4WD's.
Expert:  Buddy replied 4 years ago.
Thanks for the info. Your truck does not show it has a aftertreatment device.So that will rule out the needing a regen. It does not have any open recalls on the engine or the truck. The engine shows it has had alot of warranty repairs. I also noticed were the the turbo brake assembly has been replaced a 3 times. So this will be a place to check. I would also check fuel pressure at the filter housing. It should have minimum of 29 psi at idle and 80 – 94 at hi speed. If it is low, then you will have a problem from the pump back to the tank. I hope this helps you out. If you have anymore questions, just ask.

My father in law has a IH 574. I have super c and a M farmall. They are alot of fun.

Customer: replied 4 years ago.
great. Thanks for the check out on the VIN. Is it possible to send the report to me? I'll check that fuel pressure and exhaust brake out. Is the fuel pressure gague in the tank or external near the injector pump? I'm going to town and check it out today if the trailer is in. It's in town waiting for a grain trailer to come in so I can bring both back to the farm. I'll take care of you later on the accept. I didn't know quite how this worked and logged in and asked a second question and got somebody else who responded in a very general way. He wasn't a mercedes mechanic. He was a clark equipment guy and doesn't know the engine. I don't want to lose you and try to come back again. I've had a couple of M's and they were great tractors. They start great. I liked to hear them start and they have that smooth sound.
Expert:  Buddy replied 4 years ago.
Thanks for the accept. No need to click accept again.

To check fuel pressure, you would have to tee into a fitting at the fuel filter housing. Some have a quick connect pressure port for a gauge and others you have to tee into one of the banjo fittings with a special fitting to check pressure.If you have anymore questions, just ask. You can reply back to this post will be okay.

Buddy, its been a month since I talked with you. I went to Arizona for a while and enjoyed the warm weather. I stopped to see relatives along the way down and back. I got the fitting to check fuel pressure and its just about zero. I bought a new 100 lb glycerin filled guage thinking maybe the first one was bad but it reads nothing, however, there is fuel in the line so there must be some pressure. Can it run even with low power with no pressure to speak of? I bought a fuel pump but it looks like there might be quite a bit to remove to get it in there. Should I do it myself or is it something I should have the shop do?

Expert:  Buddy replied 4 years ago.
Thanks for getting back with me. I am ready for some warm weather. It has been pretty nice here for last couple days.
Engine should definatly have alot more pressure then that. I would recommend bypassing primary fuel system and running it straight out of a bucket to make sure there is not something else a issue.These pumps can be a pain to put on, after you do a few it does get easier.For the average person i would recommend caring it somewhere to get it replaced. Getting to the mounting bolts is the hardest thing to do, they are allen headed bolts. Once pump is off you would want to check the drive gear to make sure it is not slipping also, this was a problem on the early 4000 engines, but the truck would normally not start if this was the issue. Also were are you checking fuel pressure. Here is a picture of location, you can check it at the top fitting or the lower fitting.
If you have anymore questions, or info just ask.

Thanks
Buddy

At the upper one number 2. that before the filter right?
Expert:  Buddy replied 4 years ago.
That is the correct place to check. You definatly found your low power problem issue. If you could i would try and bypass everything on suction side and run it straight out of a bucket and see if you still have low pressure.If you still had low pressure it would have to be fuel pump,fuel pump drive, filter housing, or check valve. Couple things you can check also is to make sure that your pipe stand that fuel filter slides down over is not cracked or missing and also seen issues with the return check valve causing low fuel pressure. It is at return line at lower section of the fuel filter housing. I hope this helps you out. If you have anymore questions, or info just ask.

Thanks
Buddy
