Hi! First post here - have an old Akerman EC230B excavator and the hydraulics/ joysticks packed up today. Boom up/ down, in/ out and bucket grab/ release are super slow as if there's a lack of oil pressure. Also rotation is slow. Plenty of oil in the system. Machine seems to be tracking perfectly well. Seems to be flashing an error code 'E137' on the dash but struggling to find any workshop manuals etc.. Any help greatly appreciate! Cheers
Good day EC230B Nice to see the old beasts still running, first check the servo pressure nothing will work good unless this is performing as it should - Error 137 is for an "Extra indication" so not to sure what this is connected. Workshop manuals were never made so it is pointless to search. The servo test point is just behind the cabin you need 60 bars pressure both at high and low revolutions. if you need more help drop me a line. Kind regards Uffex
Good day I have been correcxted Volvo did produce a manual for the EC230B I am not sure how recent your machine is but much of that will match if you can find one. Kind regards Uffex
