The shaft is wider than the impeller housing , and impeller housing will only move up about 1/4 inch , it seems as if it is coming across obstruction on shaft itself
This is an old thread but I have a B100
I have followed the above but my impeller housing will only come up about 1/4 inch , and the drive shaft is wider than the impeller because the drive shaft narrows.
It looks like the only way to replace impeller is to take drive shaft off
How is this...
