    Normally this item would not be removed and inventoried separately when dismantling a machine. I ran a part number search for you and found one company with a match. Garage Alain St-Pierre 418-251-1052 Aside from that, you can go to machinerytrader.com and search the part number yourself to find matches.

    I always thought the 3rd pedal was for straight line travel on the cats ?

    HKX should have one that'll fit. Does it have to be a Cat one? Your part number didn't work in CatStore. I used a 2KW s/n, and came up with a 121-1814. $700 UsD new.

    Good day Sir From our experience you can use any proprietary hydraulic supplier providing the input and secondary pressures match that of the host machine, example pilot pressure 40 bars (Or 570 psi) output or secondary pressure 0-40 or 0-570psi normally those pedal valve may take some adaption. See KPM or Bosch-Rexwroth catalogue.You may be able to find such a control vale from a breakers yard. An alternative would be to use a switching solenoid valve, such a system utilises existing circuit controls for example the bucket controls We have done this on a number or occasions and works well providing the operator is made aware of the system. That will take care of the control options, depending on the main valve configuration we can help further we need some info. The move forward with the project drop a line with some shots of the main valve chest to [email protected] Kind regards Uffex
