B7500 Stalls w/load

[dillo99]

wow...I don't know. Definitely sounds like an air or fuel problem - one or the other is being limited somehow. I doubt it has anything to do with your hydraulics.

Thanks Mike--went to the Kubota shop--they swear its fuel so I'll drain the take AGAIN--look for water--hunt for an additive to clear injectors--and keep finders crossed!! Cats are good for doorstops and Teriyake-did I say tha outloud!

O.K.--HERE'S THE SKINNY---DRUM ROLL!!!!!!!!!! Apparently when I changed the fuel filter I forgot to fill the filter and bowl before reassembling it to the tractor. Hence the Air in the fuel system***--So to fix the problem follow the rubber hose up from the fuel filter to a nut that is between two rubber hoses. 14mm box wrench loosen the nut--have someone crank(not start) the engine--I saw 6-8,9 small pinhead bubbles come out until it "cranked" fuel--tightened her down--NO Stall w/Load-runs great--just as it begins to snow again. If that didn't work next stop loosen an injector and crank it clear of bubbles.

Interesting............my 7500 has an auto shut off when you remove the bowl. By the time it is back in place the bowl is running over. Job done.

lloydtilton,
Thanks for posting this. Could be helpful for the rest of us in the future.

My posting was a thanx for those who offered a possible solution; an hopefully helpful to those who come after. Manually filling the filter bowl leaves a "bubble". Once you get one or two threads on the stationary lid(not a firm bite) there is (I'm told later) an auto fill aspect to the B7500 that will fill the bowl to a spill over--which is what you want to prevent a bubble in the system. Thanx to Mark for the tactful observation that all was well until IK laid my hands on it and to Back track all I touched--Thanks again!! Now--I need suggestions for a reasonabley priced B7500 shop manual. Let's seee what else I can break--Thanxx all--RJ
