6341 no power

[tagew]

Hello, I have a 6341 from year -98 with 2150 hours on meter and it has very low power, specially when it is cold. Sometimes it is so low so it is nearly cant run on 5 gear with empty tractor. Sometimes it would be better after a while and sometimes not. I have replaced the fuelfilter but it did not help .I also was thinking on handbrake but it is not the problem. Has anybody got this problem or somethig like this? Does anybody have a idea where to start for solve this problem?

Br Tage W.

the front brakes could be hanging on. it has been known to happen with tractors that are not used every day.

Yes, I have also thinking about that with front brakes but after a while with driving it is not warm at all when I put my hand on it, should it not be warm if it was a problem there.
Im am thinking more on some fuel problem common for all cylinders because engine is running fine so I dont think it is something on one or two cylinders.

Yes, it was the front brakes. Some problem in air assisted headcylinder for frontbrakes, there was a lot of rust in headcylinder so I have to change it to a new one and air cylinder was also hard to move and the hole who let leaking air was full of dirt so air pressure go to brake fluid reservoir and give bubbles and airpressure into brakefluid. After change of frontbreke headcylinder and cleaning and a little lubrication with teflon on air part of this cylinder everything is working properly again. I could not find that frontbrakes would be warm even if I checked them with termal camera.
