I have put the fan into the radiator twice on the MH44, this time it did not hurt anything. I have the part at the machine shop getting repaired.
The water pump has a slide on hub for the fan that locks with a setscrew.
The first one was cracked where the setscrew goes in. I thought it would stay put with locktite on the screw, wrong.
I pulled a flange off another bad water pump I had. the flange did not want to go on the new pump, so I cleaned the inside with the dremel until it slid on, well I did not get it perfectly round and it would rock a little, well it came loose.
