Wibur Curtis Company MCD-7 - Manual (Page 4)

9. Replace with a new spring and reverse steps 4 through 7 to reinstall the drum.
10. The drum assembly should be in place with the handle sticking out from the hole on the right
side of the MCD-7. Slide the side plate through the handle and align the screw holes. Rotate the
handle so that it is pointing down. Reaching in from the top, push the end of the spring though
the side hole on the spring retainer (7). Hold on to these while rotating them (put tension on the
spring) to align with the top screw hole. Insert the screw from the outside, though the plate and
into the threaded retainer. Thread the screw into the spring retainer loosely (not tight).
11. Rotate the handle counter clockwise until the stop bar (19) hits the spring retainer. Hold the
handle in this position while replacing the arm stop standoff and screw on the bottom hole of the
plate. Release the handle. The return spring will now have the proper tension to return the handle
when pulled. The travel of the handle is also limited by the stop bar between the standoff and the
spring retainer. Tighten the screw on the spring retainer.
12. Replace the knob on the handle and put the hopper back on.
