We are trying to replace the spindle belt on our Doosan but cannot remove the air cylinder at the top of the spindle assembly / draw bar. We have removed the 4 bolts and can rotate the cylinder (until it bumps into the motor). When we try to lift the cylinder we feel a mechanical stop after about .03".
Any ideas on how to proceed? The mechanical drawings are (intentionally) vague and we can't see enough detail to determine what to remove.
Thanks for your help.
Edited- Typo on model. It's a DNM 400
Found the answer.
1) remove the 4x M8 bolts holding the cylinder down to the black base plate, remove cylinder.
2) Remove the 6x small bolts in the ring that times the drawbar to the spindle, remove the ground "rod stopper".
3) The stopper is a threaded ring. Insert one bolt into any of the 3x holes in the face of the "End stopper", stack up washers under the allen head to prevent bending the bolt. Strike the bolt with a brass punch to rotate the stopper in a counter clockwise direction (Righty tighty, lefty loosie).
4) Pull out the base plate and you're good to go. You have access to install the belt
