Short Story - blew a hose, replaced hoses, found gunk in coolant, deduced it was oil. Replaced the pump seals and botched it - had coolant leaking out the small weep hole at the base of the pump housing. Re-ordered parts and now going to give it a second try.
I think I might have put the oil seal in backwards. It looks like this (rubber ring)......
I think it goes into the impeller side of the pump with the open end showing the small spring (seen on photo) away from the impleller?
When I finished the assembly, the impeller and geared shaft were very hard to turn by hand. Is that right?
Also, any idea on what the copper ring - also in photo - is for? I don't recall taking one out of the original assembly.
It looked to me like the rebuild was not too difficult, but I think I might be losing my mind. Any advice would help.
