July 5 2020, 2:30 AM - Unplanned Generator Outage. Awoke in the morning to find the water pump seized, generator shut-down in overheat condition. Engine is #00118, Yanmar 4TN82E-UK. Closest water pump cross I could get was off a John Deere 675B skid-steer loader.

M801272 hose from pump to thermostat housing

Instead of the JD hose, I picked up a Gates 18320 Hose ($12.99 at O'Reilly's) and cut it to fit-- it's got a tight bend that 3/8 heater hose won't do.

The Water Pump was a eBay clone for $75 shipped. but it came with the Yanmar part number 129002-42004 taped to it's box and the gasket too.

I'm not sure how full the system is... the hose to the top of the radiator is mighty soft and squishy. Generally not thrilled by how the cooling loop is laid out, but it should work for now. I will be checking level next few times I run it to hopefully burp the air out.

The foam sound/heat insulation in the generator bay was crispy and failing. This will be replaced with fiberglass duct board, or maybe some Roxul foil faced mineral wool board. I'll also need to get the fans above the generator functioning again.
