D6 underwater

Bluecat · 2025-02-11 00:06

Rain came unexpectedly and flooded the area. The machine was about halfway submerged. Replaced the batteries. When draining the oil there was 13 gallons of water that came out first. The fuel was full of water as well. Both have been drained and refilled, the filters changed. Engine still seems hydro locked. Starter engages but won’t crank. Still have full power, no codes. What should I do next?

    I would pull the nozzles and turn it over by hand to force water out of cylinders

    You may have a bent rod at this point.

    After you do what pittsburg cat man says, could you do a compression test and find out if you had a bent rod that way? If not what's the best way? Just thinking out load here.

    Problem is that a rod can be bent just a hair and appear normal, but will grenade or start knocking eventually. Only a disassembly can tell foresure, but that being said lots of people have taken a chance and got away with it. Others have not been so fortunate. Simon C

    Seen a Cat excavator that got drowned that an electrical charging problem. When they opened the bonnet they noticed the alternater missing ,so was #1 piston. Yep the oils and filters were changed but the injector weren't pulled. It only takes a few drops of water on top of the piston to bend a con rod.

    Even if the engine mechanicals are ok, the electrical gremlins that swam in and made that machine home will never ever go away . . .

    Unless if a new harness is available or the old one can be repaired. On the old stuff, there was not a lot of wiring, but on new stuff, your going to have fun. Simon C
