Dave, I thought I still had a pretty good recollection of that nightmarish arrangement. A stainless socket head screw to replace the one that’s in there would make it easier. It is very tight in there. I’m sure the clip made.it easier to deal with in later years. I’m glad the impellers on these seem to last quite a while. Replacing it again is not a job I look forward to. I used all sorts of magnets and pliers and whatnot to get that screw back in.

Yes – I’ve already checked and the screw appears to be a 4 mm metric that’s 3/4 inch long – I’m going to get a hex or allen head for it. i don’t know if it’s always been really tight ir if the plastic it threads into shrunk slightly over time tightening it’s grip on the screw.

I pried the plastic parts the screw goes into off the metal shaft they pivot on with the screw backed out almost all the way, but still with the pin through the shift rod – I think I can start the new screw in those parts a couple turns before I put them in the motor and then put together in reverse order of my disassembly so I do’n risk losing the screw. I just have to watch I don’t drop parts 36, 37, and the screw down the housing.
