As a winter project, I've taken the water pump and heat exchanger off my Onan 7.5KW MDJE genset for some PM. The heat exchanger is cleaning up nicely. That's good, it's a $550-$700 part.
The water pump works, and really had no problems before I removed it. However, there's minor corrosion below the weep hole, even though I never saw any evidence of an actual leak. On the off chance the seal is leaking, I'd like to either rebuild it or buy a spare.
But, OMG they want $1,400-$1,700 for the replacement pump!
It's just a pulley-driven impeller pump. Theoretically, I could mount any old pump there, as long as the flow rate matched. I'd just have to drill and tap new mounting holes if they didn't match up.
Any reason this would be a bad idea? Anyone know a good shop on the East coast that does pump rebuilds?
