Impeller Half 03807000

Hello Gene, thank you for your question. You should not have to remove the shaft. Here are some instructions from another customer. " I had already removed the broken impeller using a socket set to remove the bolts holding it together. When the new part arrived, I simply fit the slots in the new parts on the pins, held the two pieces with one hand while placing a bolt through the pre- drilled holes. It was easy and took maybe 15 minutes to replace all of the bolts and snug them tight.". I hope this helps!
