While waiting, rotate the shaft several times to distribute the oil.
4.
Slide the shaft wrench (A05107A) over the shaft (122) and key.
5.
Rotate the impeller clockwise (viewed from the impeller end of the shaft) and raise the wrench off of
the work surface.
6.
To loosen the impeller, quickly turn the impeller counter-clockwise (viewed from the impeller end of
the shaft) while impacting the wrench handle on the workbench or a solid block.
7.
Repeat step 6 until the impeller becomes loose.
8.
If step 6 and 7 do not work then do this:
a) Place a socket wrench over the cast nut on the impeller hub.
b) Turn the impeller counter-clockwise (viewed from the impeller end of the shaft).
Be sure that the impeller wrench rests on the workbench or a solid block and that the power end is
secure on the work surface.
