In your very detailed paper you write :
Now I just need to get 2 thumb screws out and two slackened to change the impeller
May I add one piece of advice based on pratical experience as one day or another a screw or a bolt will escape your fingers and fall into that extremely deep pit that houses the engine, so deep that human hands cannot reach the bootom watever the location of the human body. Of course a magnetic ‘finger’ will help provided the screw is made of magnetic stainless steel.
This is why I always install a robust bag under very close to the candidate falling bolt, screw or filter or whatever is the candidate, supermarket bags made of thick platics being ideal.
