    Ex 60 track runs slow in forward & fast in reverse

    if it were a main relief valve then the rest of the machine would be effected. to eliminate that possibility you would check you pressures on all your circuits by going into service menu and stalling it out. The pressures should be the same. the boom may have a boost pressure on it may be a...

    NEED HELP WITH HITACHI EX 400lc-3!

    when booming down I helps retard the cylinders so it will not run away on you and hit the ground hard. sometimes when they get stuck in just the right position they will cause the boom to raise very slowly. This is just a check I do when there is contamination in the control valve especially if...

    Alternate route for hydraulic plumbing????

    I to agree with John C , cause I have done the same thing only I bought the weld able fittings to go onto the pipes. you can get them in J.I.C. or a split flange. worked really well and cost effective.

    excavator boom not moving

    If all the other controls work then it just in the circuit for the stick. This will also tell you if you have a pilot problem or a delivery problem. If none of them work then look at all you filters first(pilot and main hydraulic filter). Its cheap easy and you will know if there was a...
