My New Holland c 175 loses power after throttling up
For most to provide input, in most all cases it requires a bit more then "loses power after throttling up ". What have you checked? Are the fluid levels OK? Has the hydraulic filter been checked or replaced?
yes, all fluid levels are good, Machine was just serviced 25 hrs ago
What exactly is losing power? Are you talking hyd. function, engine power, elec? If you are talking engine power, most likely you either have an air restriction or fuel restriction. Thee are some other possibilities, but let's not go there yet. Hydraulic power loss at throttle up doesn't make much sense unless there is a filter restriction, or in some cases there is a suction screen in hyd. tanks that can get clogged. If you could describe to us what is happening maybe we could help out better.
Not sure about a NH C 175 but my NH 665 has a like problem a few years ago. I finally found a small inline fuel filter hid up in the left back corner top of the radiator. Mine was plugged. I had replaced the other canister fuel filter/water separator and never new that little bugger existed. A new one took care of the problem.
Being in NY it starting to sound like you have water in the fuel lines or tank somewhere. Pull the fuel filter back off and check for ice in it, then get some Power Service 911 and put in the tank. Your diesel could also be gelling up
I have done the diesel 911 & cleaned the filters, I have fuel in it that has 2x the additive and was road diesel. I am wondering if the line coming out of the tank to the pump has a mesh filter on & if so how would I clean it? Im planning to remove the fuel line from the tank and using an air gun to blow back on the fitting into the tank.
Sounds like a good plan
blow back failed. Wondering now if is air?
Did the air blow back to the tank and you still have the issue, or did the air failed to make it back to the tank?
If the engine has no power because the air is restricted, it will usually blow black smoke (unless it has a manifold pressure sensor to keep the engine from overfueling). Also pretty easy to check the air filter, clean out the housing and run it without the filter for a minute to see if that's the issue (be sure NOTHING can get sucked in there obviously).
The blow back did allow air into the tank and i gave it half dozen blast. smoke is white from exhaust.
White smoke means the diesel is not being burned completely. Most probable causes I think would be either low compression or contaminated fuel with water, or something else. Where do you get your fuel and is this a possibility?
Fuel starvation will cause funny white smoke like this, the injection pressure doesn't build fast enough and the injector opens late, so the "compression" is WAY low, or there's not enough to light it at all and it goes straight out the muffler. If you want to know for sure, tee in a pressure/vacuum gauge before the injection pump and see what the pressure is when you start it, and then when it loses power. There should be a clear difference. Then move the gauge back toward the tank...
