| Abstract: | An excavator after over-haul to its valve group could only lift its boom slowly and could not even lower it again. Following analyses and disassembly found that the trouble lay with wrong assembly of spool in the reverse valve for the boom, and the trouble was eliminated after reassembling the very valve. |
