I replaced the pump on my raw water pump -- it was a JABSCO 2620 and had been unmaintained for entirely too long. I replaced it with an identical model to be sure mounting would work. I tried to replace the pulley itself, even buying the identical Chicago Die Cast 400A pulley. The pulley arrived WITHOUT the cutout for the key on the end of the Jabsco shaft, so I went back and reused the old pulley. I ran her seemingly without trouble for about 20 hours over the last two weeks. I checked several times over the first few hours, and didn't notice anything wrong.
Today I took a look for a different problem, and was horrified to discover bronze shavings all over the engine compartment. Apparently the pulley had slipped down further on the shaft and scraped along the outer edge of the pump. Currently, the pulley is not even remotely in contact with the pump, so the pulley is definitely sliding along the shaft while it spins.
It's not directly an Atomic 4 question, but I'm hoping someone has some suggestion on how I might keep the pulley in a fixed position along the pump shaft. Help?
