Re: Water Pump Replacement

Harbor Freight sells a cheap 4-1/2" grinder on sale for $9.99. This can be fitted with either the typical "cup" wheel (actually more dishware than teacup) or with a THIN blade (typically 0.040...

Re: Water Pump Replacement

Likely you would have the same issue with a replacement - or maybe the converse - shaft too short resulting in too much forward-back movement of the shaft/impeller. Sellers generally sell what will...

Re: Water Pump Replacement

Best would be to disassemble the pump and turn the shaft in a lathe.

Given you likely don't have one, an alternative might be found in holding the entire pump in a vise, and by using the fan,...

Re: Water Pump Replacement

The $1 water pump I referred to earlier is now disassembled. It was seized and it took some doing (and a punch and hammer to unscrew the gland nut) to allow removal of the shaft.

Re: Water Pump Replacement

If the pump spins as it is built (check with the fan on) then you can cut down the nose (center shaft extension at the impeller) so without gasket it fits "tight." The additional thickness of the...
