HI Im having problems with my d6r it has no power i changed both the primary and secondary fuel filters but that did not work it just turned over 4000 hrs i checked to see if the line from the tank is open its fine i can get rpms on the dash but it has no grunt its like working at half throttle in first gear i stuck the blade down deep and could only get 1250 rpm any body have any ideas
Its not the same, but it maybe
When you open the throttle full open, fast, do you get a little black smoke?
My dump truck Ford 3306 Cat, starting having low power issues(no black smoke) I changed every filter I could find, I thought it was the turbo, checked it and it turned OK, no binding. I was connecting the inlet hose to the turbo and just happen to hit/bump one of the steel lines on the back of the injection pump, I noticed the line was broke at the nut and the line was just bouncing back and forth, causing the aneroid valve not to open causing low power. If I hadnt found this, I was going to have the diaphragm in the aneroid changed, its something I didnt want to tackle.
Installed new line and the power was back and the little smoke.
If you have a air cooling radiator, check the hoses, they get leaks and suck outside air. This is usually blue or red hoses about 3" X 6"
Do you hear the turbo spool up?
These things are usually simple, but tough to find
Good info on this site
Good Luck
