    Cat 257B 2 down on power

    Thanks for your help. The silt is accumulating in the small filter between the tank and the engine mounted transfer pump. I'm considering getting a hand pump and syphoning the last qtr tank out through the fuel pickup to try and speed the cleaning process. Those small filters are $13 each, so if...

    Cat 257B 2 down on power

    Thanks for the diagram..it really helps.I am using the machine daily (building my own house) and cat dealer is 1 hour round trip away, so I can't spend a whole day repairing, so I will have to take it in steps. I removed the fuel line, cleaned lines and changed the small filter.it was loaded...

    Cat 257B 2 down on power

    After THOROUGHLY cleaning the engine compartment, I can get a better view. After putting a light close to the small fuel filter and shaking it, I can see some garbage that has settled in the bottom. I will change it shortly and run the machine for awhile and see if that could be the issue (or a...

    Cat 257B 2 down on power

    I don't have a pump on top of my filter except "hand priming button. I have 3 fuel lines that go through the lower bulkhead: 1 goes to the injector rail (I assume return to tank) 1 goes to small filter before 3 inch pump mounted on side of engine (I assume it's called transfer pump, from this...

    Cat 257B 2 down on power

    I called cat today and they said $98 for a "transfer pump" I asked if that was the only one they had and they said "no, they have a priming pump also" I didn't get the price since they mentioned the transfer pump first. I asked if the priming pump was primarily for starting or running and the...

    Cat 257B 2 down on power

    I disassembled the fuel cap and cleaned the foam filter....It seems to be getting worse. It's doing it now at 1/2 tank when on an incline. It did it today and I opened the cap. It did not help the problem. It was still down on power and didn't get better after a few minutes. I refueled it and it...

    Cat 257B 2 down on power

    I listened for the pump and couldn't hear anything obvious (although it's hard to hear with the stupid beeper going.. I still don't know what purpose the beeper serves since I sat in seat, lowered arm, fastened seatbelt and beeper still goes....maybe a battery run-down protection) Anyway, best...

    Cat 257B 2 down on power

    Except for suction the first time, haven't really noticed any. Will listen for fuel pump tomorrow.Do the pumps go out gradually or just quit for good? I.e. Work intermittently? Or would it run for awhile without the pump working, and just bog down when you burn some fuel off and get on a slope...

    Cat 257B 2 down on power

    The filter was changed by the dealer when I bought it. I have "looked at the separator" (the clear bowl right?) but have not emptied it since it happened on 1st, 2nd and 3rd tank of fuel since it was changed and it didn't appear to have any water in it. I' m suspecting the cap too, mainly due...

    Cat 257B 2 down on power

    I have a 1900 hr 257b that I just bought. Near the end of the first tank of fuel, it went down on power(like I let off the throttle) it would surge like it was starving for fuel. When I took the cap off, it was "suctioned" to the tank. I refueled and it worked normal for quarter of a tank then...
