    B7500 wont rev past 2,000 rpm

    Mines an 2003 with 330 hours on it. The weirdest part is how it was working one day and then the next it just started going to 2300 rpm. My 03 chevy dually I have had the cluster rebuilt twice in it so I guess the tach on my tractor not reading right isnt that unfeasible.

    B7500 wont rev past 2,000 rpm

    The dash has a line at 2600 rpm saying 540 PTO. So I going off that assuming that if my PTO is at 540 rpm then the engine must be at 2600 rpm and not the 2300 rpm indicated by the tach.

    B7500 wont rev past 2,000 rpm

    Tested the PTO RPM today. When WOT (tach showing 2300 rpm not 2600) where the 540 PTO line is at the PTO is at 542 RPM. So if the RPM is at 542 rpm then the tach must be off correct?

    B7500 wont rev past 2,000 rpm

    Called injection pump service place here and talked to them for almost 30 mins. They felt like it was not the injection pump based on everything I tried and how the tractor was running. They told me to test the PTO RPM so I ordered a $20 tool to test the PTO RPM. If it 540 rpm then its going to...

    B7500 wont rev past 2,000 rpm

    It's hard to say if the tach is correct. It seems correct. Hooked up my 4 ft shredder and shredded 1 acre and rpm never dropped any whole time. I checked the linkage again, both foot feed and hand throttle are going all the way to the stop. Does these have injection pump?

    B7500 wont rev past 2,000 rpm

    The air filter is brand new, I also pulled the air filter out and it didn't change the rpm any. I checked the linkage and both the foot pedal and hand level are making the linkage go all the way to the stop. The linkage adjustments look like they have never moved since everything looks equally...

    B7500 wont rev past 2,000 rpm

    I unhooked all the fuel lines and drained about 2 gallons of diesel out and changed the fuel filter. The filter looked pretty good, had just a hair of trash in it. All the lines had diesel flowing out of them like crazy, none seemed restricted. The tractor revs to 2200-2300 ( thought 2000) rpm...

    B7500 wont rev past 2,000 rpm

    I use my B7500 every couple days usually, when I got on it the other day it wouldnt rev past 2,000 rpm. I used it and tried rev'ing several times and it would always stop at 2,000 rpm. I took the covers off and verified the linkage was still going all the way wide open and it is. My next step is...
