Then the top and bottom of the conical burr, and the flat area in the middle of the
aluminum holder for the bottom flat burr ('burr driver"), which abuts the bottom face of
the bottom conical burr.
In all cases of precision reassembly, rotate mating
parts against each other and by doing so make
certain by sound and feel that contaminants haven't
fallen into mating surfaces.
Install the screw (with moving wiper) in the center of
the rotating burr assembly. Tighten the screw while
holding the shaft by use of the pin.
Install the static wiper. It should be just clear of the
rotating burr assembly. The foot of the wiper that goes under the screw head should lie
alongside the static flat burr. Use a business card or similar to set the leg of the wiper to
just clear the moving flat burr. Make certain that the
moving wiper does not hit it. The screw must be
firmly
tightened or the wiper can rotate out and
interfere with the moving wiper.
When you reinstall the bottom funnel, you should
likewise rotate it against the mating surface at the
top of the funnel to make sure it mates cleanly with
the mounting surface. Then loosen the hollow nuts
that retain the clips, slide the clips into the slot in the
bottom funnel and retighten them.
The moving wiper should run just clear of the inside of the bottom funnel. The
clearance should be about the thickness of two business cards or less. This is a
precision part and was checked on assembly. If the wiper has too much clearance or
rubs against the bottom funnel, it has been bent out of shape.
