  1. Well. The valve block had an internal fault. It would have had to be sent away to a specialist, so they replaced it with a secondhand one free of charge. Machine is not even in warranty, so very good of them really.

     

    sounds more like an inherent fault if the dealer replaced it for nowt

  2. I am starting to suspect some kind of debris lodged somewhere too I have removed three pressure relief valves now, and cleaned them with an airline, so starting to suspect the block where the oil comes into before the valves operate the tracks is the fault.

     

    stop farting about and stick a guage on it until you do its a total guess

  3. I must have inferred something wrong from what Breezeblock had found then.

     

    I thought top high speed was with both pump outputs controlled by a pressure operated diverter valve.

     

    it is according to the diagram but the pressure gets limited to 120bar the 2 speed part is controlled by a solenoid

    did you get a gauge on it yet until you do its just guesswork

    ps excuse my poor English I am **** at explains things

  4. I've had a look at the diagram and from what you describe it looks like the 3cc section of the pump is bypassing the valve limits it to 120 bar when its activated bringing in both pumps to increase the flow and 170 bar when its not so you definitely need to start by putting a gauge on it

  5. tdl is my employer and we are the only sany dealer in the uk have a look at sanys website they do a huge range of equipment and are one of the biggest manufacturers in Asia I have had a look at them and they seem pretty well screwed together Malcolm plant and ab2000 in Scotland have started buying them as well they use the same components as most other manufacturers there are some pretty good deals to be had

  6. i agree, hmm a crafty fellow might but a straight through exhaust and bypass it. put a blank on the return.:thumbup:

     

    you can't do this as the pressure across the dpf is monitored by the ecu all the time thats how it knows the restriction is there and its also got a thermo couple in it as well the only way to get around it is reprogram the ecu and get shot of the egr and the dpf or buy a machine from abroad without all that crap fitted
