So, with all the rain we've been having we haven't had to pump water for a week. But we forgot the pump was still at the dam...and was under two-feet of water!
We dragged it out yesterday but I haven't decided how to approach it just yet.
I'm thinking I'll drain the crankcase, put in a litre of diesel and slosh it all around to try to clean it out. Pull the plug and spray WD40 into the cylinder to break up any water in the ring grooves, then drain the diesel overnight, fill it up with fresh oil, run it for maybe ten minutes to clean out all the galleries, then drain and refill it with fresh oil.
Anybody had to deal with something similar, I'm sure it happens a lot
