1.08 If the impeller does not immediately
come off of the splined shaft, use the
BK01MK04 Impeller Extraction Tool.
Bolt the extraction tool to the impeller
using (2) 5/16–18x1” long shoulder
bolts. Hand tighten a ¾-10 jacking
screw into the center hole until it
presses against the shaft.

the
disassembly.
Using a socket or wrench, continue
tightening the jacking screw until the
impeller breaks free and slips off of the
shaft.
Note: The impeller is dynamically
balanced
and
should
be
replaced if signs of damage or
excessive wear are detected.
1.09 Lift the top assembly off of the crates
and set on top of blocks placed under
the diffuser cover as shown below.
Ensure the blocks don’t block access to
the (3) socket cap screws on the
underside of the diffuser cover. Keep
the overhead lifting devise attached to
the Lifting Hanger shackle for stability.
