on a Pinnacle PFII-P1 1-21-E01 / 34-2853do I is the impeller 'screwed on the motor shaft' with 'left-handed' thread? and HOW do I unscrew it to replace the gasket behind the impeller? What do i hold on to to unscrew it?

A  Answered on 11/5/2022 by InyoPools Product Specialist Hector F.

Hello Seikhaus, yes these impeller screws reverse thread to the motor shaft. You will want to hold the shaft steady at the end/back of the motor where it is squared using a wrench. Here is our "How to replace a pool pump motor" general guide that should offer some clarity with that.
