REMOVAL
1. The blower housing face must be removed to gain access to the
impeller. Use an overhead crane or forklift to support the face while
removing.
2. Once the face has been removed, remove the shaft protector (Fig. 1
or 2).
3. Saturate the shaft and bushing using a penetrating lubricant to help
loosen the bushing. Clean any grease or debris from the bushing
and shaft.
4. Remove the 3 bolts attaching the bushing to the impeller.(Fig. 3)
Being careful not to break the bolts. If a set screw is on the lip of
the bushing, loosen it using an allen wrench.(Fig. 4)
5. Using two of the bolts that were just removed screw those bolts
into the threaded holes on the bushing. Drive the two bolts into
the bushing.(Fig. 5) This will separate the bushing from the impel-
ler. Alternate from one bolt to the other driving only about a 1/4” at
a time to keep the bushing coming out straight. It is imperative to
keep the bushing straight to remove it.
IMPORTANT: Be sure to drive the bushing out evenly or it will get in a
bind making removal much harder.
6. If the bushing does not come off using the two bolts, drill and tap
several additional 3/8-16 holes around the bushing. Using Grade
8, 3/8-16 - 2 inch bolts, alternately drive the bolts 1/4” at a time to
remove the bushing. KEEP THE BUSHING STRAIGHT while
removing.
IMPORTANT: If additional holes were drilled in the bushing, it can not
be reused. It must be be replaced.
7. Once the bushing has been removed use an overhead crane or other
suitable device to help lift the impeller out of the blower housing.
8. At this point it would be a good idea to inspect the blower housing
liners and blower housing for any damage or wear. Any damage or
wear to the liners should be fixed by replacing the liners immedi
-
ately.
