With Or Without An Elevator - Graco 25C483 Instructions-Parts List Manual

With or Without an Elevator

1. Install the agitator shaft (33) by threading it into
the stub (6) on the bottom back gear housing (1).
See Figure 2.
2. Slide the agitator shaft through the large hole in
the center of the drum cover.
3. Rotate and align the three tapped holes in the
bottom of the housing with the three through
holes in the drum cover.
4. Thread three hex head screws (45 not shown)
with thread sealant (not provided) up through the
drum cover and into the bottom housing. Torque
them to 75 in-lb (8.4 N-m).
5. Assemble one pair of agitator blades (34) so that
the four through holes in the blade halves are
lined up.
6. Push four cap screws (35) through the four holes
in the blades, and start the four lock nuts (36)
onto the cap screws.
7. Slide the loose blade assembly up the shaft, and
position it approximately 13 in. (33 cm) from the
bottom of the shaft.
8. Tighten the lock nuts evenly to draw the blades
together until they are tight on the shaft. Torque
the locknuts to 50 to 55 in-lb (5.6 to 6.2 N-m). A
gap will remain between the blade halves.
9. Repeat steps 4 and 5 with the second pair of
agitator blades.
10. Position the second blade assembly near the
bottom end of the shaft, but not on the bottom
plug (40).
11. Rotate the lower blade assembly so that it is
oriented 90 degrees relative to the upper blade
assembly, and torque the lock nuts to 50 to 55
in-lb (5.6 to 6.2 Nm). A gap will remain between
the blade halves.
