OK GC down… when I took out he GC -drive shaft …. found no ROLL pin below the upper brass cup… I will try local hardware store
water pump impeller looked fine bent blades (nornal & flexible) so the last guy who worked on it likely destroyed the roll pin, just took
it out or just forgot to put it back although removal was unnecessary
pump housing got a good brushing small holes cleaned out… new China impeller 277181 going in…same size as the old one strangely for China it has bigger brass core . should be ok …
