you were right...I need to buy a hydraulic trolley to move this heavy excavator.

hi kevin,
from the dimension you gave, i assume its a 20mm dia bore cyclinder, which same as mine. i am using this for the 650:




its an industrial pump. the flow rate for the pump its 0.2cc/rev and 0.1cc/rev. directly couple to a outer-run. it able to perform smoothly.
what do u think kevin? i can sell this to you as used parts for RM600 a pump attached together with outer-run as a set.

[while i just got a smaller pump, believe to be lower flow rate but able to deliver enough bar, run smaller motor for better energy efficient, but yet to full test it.]
