Inquiry (采购产品): NABCO PUMP I have a Koehring 6608 excavator with an Isuzu 4BB1 diesel engine with a NABCO hydraulic pump bolted onto the output end of the engine. I see no numbers on the pump but it is a bank of three pumps bolted to each other in tandem. Two of the pumps will not adjust at the OV valve and I suspect they may be bad. Where can I have the pump tested and rebuilt if necessary? What would be a coste estimate for this work? Best case worse case?
