Service
If the unit requires more than installation of a service kit,
it is usually quickest and easiest to send the unit to the
Graco distributor for repair or replacement.
•
If the vanes need replacing, or foreign material is
present in the motor chamber, an experienced
mechanic may remove the end plate opposite the
drive shaft end.
•
New vanes should have the edges with cut corners
(or the notched edges, if the vanes are reversible)
pointing toward the bottom of the vane slot.
Remove the Siphon and Helix
Tubes
1.
Remove the bearing nut (8). See F
. 10.
2.
Remove the two diagonal socket-head screws (24)
and lockwashers (25) protruding from the top of the
siphon cover (6).
3.
Remove the siphon tube (4) as follows:
a.
Rest the agitator on its side on the drive belt
housing so the inlet is lower than the outlet. This
orientation prevents fluid from running into the
bearing and drive belt area.
b.
Pull up on the fluid outlet fitting (41) to remove
the siphon tube (4).
4.
Remove the three hex-head screws (14a) from the
bushing (14), and install the screws into the
bushing's threaded holes as shown in Detail A of
F
. 10. Tighten the screws evenly to loosen the
bushing from the helix tube (7).
5.
Pull the helix tube (7) through the bottom of the
agitator housing (3).
Moving parts, such as an impeller blade, can cut or
amputate fingers. To reduce the risk of serious injury,
always shut off the agitator and disconnect the air line
before moving, checking, or repairing the agitator.
NOTICE
Do not pry with a screwdriver. It will dent the surface of
the plate and body, causing leaks. Use a puller tool,
which will remove the end plate while maintaining the
position of the shaft.
