Re: [DML] Water pump pulley came off on its own

["Harold McElraft" <hmcelraft@xxxxxxx>]

I have not seen one of Grady's pumps but this surprises me. The 
pulley should be a tight compression fit. Is the pulley split or 
broken any where?

If not broken, one quick way to fix it would be to put on the pulley 
and use the tapped hole in the pump shaft, used to "press" on the 
pulley, to hold the pulley in place by putting a permanent bolt 
there? You would need to get the washer sizes correct because the 
pulley completely pressed in place may expose some shaft and a 
washer will have to be used to fill up that gap and make a tight 
fit. I'd also use some lock-tite to be sure the bolt stays put.

Another way would be to have the front extension metal of the pulley 
drilled and tapped for a set screw. Put the pulley on - "press" the 
pulley on to the shaft - be sure to get it all the way on - tighten 
the set screw. The weight of the set-screw will off-set any drilling 
done so balance should not be a concern.
