T&T: Changing John Deere Raw Water Pump Impeller

[Jim Ague]

>> The impeller acts as if it is restrained by something.

I've found a flat blade screwdriver can help. Stick it part way in between a 
pair of vanes. Press the blade against the shaft part of the impeller and 
use the housing of the pump as a fulcrum to work the impeller out. Pulling 
with a needlenose plier on an opposing vane at the same time helps create a 
wiggling action.

Using a plastic wire tie or two to squeeze the vanes of the new one always 
helped me get it back in.

>> impeller moved very little.  I then sprayed PB Blaster thoroughly in and
>> around the impeller and giggled it to allow the fluid to seep into 
>> cracks.

Jiggling will help much more than giggling. This is no laughing matter.

And don't be afraid to use sailor talk as necessary.
