6. Apply a layer of bearing lubricant 1/4 inch high to the seat of each wear
saddle, making the layer as wide as the saddle and touching the rear
angled surface.
7. Install one platen adjust bracket and platen adjust bracket bushing
together onto the longer platen shaft, with the screw at the top of the
bracket. Keep the bushing installed in the bracket with the open side of
the bushing facing downward.
8. Place the remaining bracket and bushing onto the left side mechanism
base platen seat so that the seat is between the flanges of the bracket and
the bushing. The open side of the bushing should be facing downward.
9. Insert the shorter platen shaft through the bushing and bracket and
through the opening in the left side plate. Rotate the longer shaft into the
opening in the right side plate and position the adjustment brackets with
the bushings as shown in Figure 5–4.
The open side of each bushing must face down so the platen shafts can
rest on the wear saddles and the machined base platen seats are between
the two flanges of the bushing. Each bushing and bracket must also be
centered relative to each other.
