g. Locate feed plate (D) on the disc ensuring that

hole in feed plate registers on disc. Position
plate approximately as shown and align holes.

IMPORTANT

Feed plate should be located so that when
holes are aligned, the leading edge of the
feed plate (D) is further from the
accelerator (E) than the trailing edge.

NOTE

Older type feed plates may required
trimming to properly locate on disc.

Locate feed plate (D) on disc and scribe a
trim line on feed plate to clear the
accelerators (E). Trim feed plate to suit.

h. Re-position deflector (C) and align holes.

i. Re-install bolts (B) and tighten to 92 ft·lbf (125

N·m).

Repeat above steps for opposite side.

k. Manually rotate discs to check for interference of

feed plate and adjacent parts.
