New Holland L565 Losing power

ncaaref · Dec 9, 2016

Hi all I have a New Holland L565 that has been losing power when under a load. What I have done thus far to fix it is;
Replace both Fuel filters
Replace both Air Filters
Took apart and cleaned injectors (A Side not here, After doing this I am now getting blue smoke while it is running.)

None of the above has worked. What am I missing and where do I go from here. I can't even back drag without it bogging down.
thanks

Make sure that you don"t have a fuel restriction between the tank and the pump. There is a strainer at the discharge of the fuel tank that can clog, the line from the tank to the filter can clog or be pinched, the fuel filter head and be obstructed, the line from the tank to the pump and be blocked or pinched, if you have a lift pump I may have a filter that"s clogged or the pump is shot. Changing the fuel filters is the easy first step and that didn"t fix it, so you have to look for other causes.
Blue smoke is lube oil burning and that"s another issue. Worn rigs is the usual cause of that. But if your machine was running well and now it"s lacking power, I"d suspect inadequate fuel delivery. Worn rings are a gradual thing usually caused by wear.
