While the impeller rotation still has a block (Figure 2), use a piece of long, heavy bar
to lever against the arm of the lathe dog in a counterclockwise direction (You should
be facing the drive end of the shaft.). Be very careful and avoid damaging either the
keyway or the shaft. Once the impeller is dislodged, take out the lathe dog, the wood
block and the key.

Remove hardware attaching the rotating assembly to the pump casing. Use the
jackbolts to detach the rotating assembly by pulling directly away from the pump
casing, then tag and tie the rotating assembly shims to simplify reassembly.
NOTE:
If you prefer, a tool for disassembly may be obtained from Weir Specialty
Pumps. Should you select this option, follow all instructions included in the
package. You may construct a tool that is similar if you use a ½-inch pipe
made of schedule 80 steel or malleable iron with a standard tee connection
(Figure 2). All threads should be ½-inch NPT. Do not build the tool
beforehand.
