David, Tip 1: You should be able to free the impellor by bending/moving one rubber vane tip, one at a time clear of the bronze housing. Start w the straighter ones and just nudge the tip away from the housing and let return. Do each one, one at a time, all the way round or enough to free the impeller. I don't hestitate to do this by hand or with needle nose. Just be gentle.
Tip 2: The curve of the impeller vanes indicates the rotation. Mark the rotation on the housing to help with re-assembly.

I gather that if I pull with pliers, it might happen? So I really need an impeller puller? Dave On Mar 23, 2014, at 9:00 AM, dwight < dwight...@gmail.com > wrote: David What water pump. I have a Sherwood pump on mu Universal M4-30 and I need to be very careful when pulling the impellor off the shaft not to disengage the impellor drive shaft out altogether…if I do that the job of impellor replacement instantaneously becomes a much bigger job.

I tried to use it yesterday and found that there was very little space between the back of the impeller and the housing of the water pump, so I could not get the arms of the puller to grab anything. The arms on the one I bought are quite thick. Do I need a different tool?
