My cousins farm was flooded and his 42,000 lb. Hyundai excavator which was sitting on a levy became partially submerged and will continue to be for another couple of days. So it will have been submerged a total of about 3-4 days. The water didn't make it up to the engine but there was about 6 inches of water in the cab and of course the entire undercarriage was submerged. What do you recommend doing before he fires it up again?

Thank you.

KwD75, I apologise for not replying sooner. We had a Komatus 400 go into the river in the San Juaquine River delta in California at 4 months of age. It was nose first with the batteries going under water. The water is subject to a 2 to 3 foot tide so it is quite brackish. The machine was only under for 4 hours because we luckily had a 300 ton hydro on site. The batteries were so dead they would not take a charge the next morning.The current from the batteries went to groumd through the swing bearing causing etching on the balls and also on the race. Even if the batteries didn't discharge water and silt will get into the swing bearing and it should be checked out while the insurance co. is still on the line as a premature failure later is very expensive. Also check for water getting in to the swing transmission through the oil check dip stick. Due to the corrosive water on our site every wire,electrical componate, circle bearing, and swing transmission bearings had to be replaced. VERY EXPENSIVE Good Luck RT

Be sure to grease the swing bearing every few degrees while swinging the machine to flush out the mud and water the best you can.

We do this every few weeks anyway to make sure the bearing is clean and greased up good.
