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. _____ From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of David Knecht Sent: March 23, 2014 9:49 AM To: CnC CnC discussion list Subject: Stus-List Impeller/gear puller I need to change my impeller and after an earlier discussion and difficulty removing the present one, I purchased an inexpensive gear puller to remove it. 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?
