there should be a small filter in the top of the priming pump or it may have a filter in the bolt of the pipe fitting coming from the tank,bleed the first filter first then the second one there may be a return line on the top of the injector pump bleed this aswell,thats the procedure for bleeding my 956 the injector pump on your tractor will be a different model.how did you get on with the brakes?

no primer pump on these, so think you bleed from the injectors, found dirt in the tank and blew it back with compressor and all flowing well again but will not start.... never got the brakes sorted but will shortly

Both fuel fillters full? I dont no much about that make of tractor ,I find it hard to believe there is no primer! have a look for a bleed screw on the injector pump, if you find one, leave it open and crank the tractor for a while,once you have diesel there start bleeding off your injectors.

does it make any differance when it put to cold start position?

its doesnt. it got a unusual injector pump on it, 4 pipes going in the side, the 2 on top one from the tank and one going out to the injectors but no nut on it so you could bleed it or anything

sounds like a strange kind of pump,is the return line easly identified? you should be able to bleed through that.could you post a pic?

Thelostcountry

John J. Lyons

will try and post pic later,
I opened the pipe from the tank to the pump and i get got good flow of diesel coming into pump, closed this and then opened the pipe leaving the pump to the injectors( and you could hear the release of air for a few seconds) and not getting any diesel flowing when i turn the engine over
i give it a little squirt of Easystart and no go either
