can diesel harm hydraulic system?

so we had a little mishap at the pump last night, my guy opened the back of the skidsteer (to get access to the diesel cap, and instead of opening the diesel cap, opened the hydraulic fluid cap, and the resevoir was filled with diesel!!! (damn case for putting both caps in similar areas/locations, anyways, we loaded the skid onto the trailer, and promptly got it back to the shop, drained all the resevoir, so the question here is, if diesel is a oil base, and our skidsteer uses 10w30 as hydraulic fluid, when we put the new fluid in, do we need to do a flush? or well the little bit of diesel that is still in the system just mix in with the 10w30? i am leaning towards draining it again and replacing the fluid a second time, but would love to hear thoughts on this

I think you are on the right track. You may want to run it a bit between changes.

just talked to the dealer, he says the diesel could soften all the rubber seals, in pumps, hoses, valves, rams, etc, praying the flush is going to work

The only harm it does is weaken the seals. If you didn't run it with fuel in it and drained it you should be fine.

It always amazes me as to how people can do this. Are you in that big of a hurry or are you that blind to not see where you are putting the fuel in your machine, not trying to pick a fight, but honestly.
I work part time for a rental company and 2-3 times a year someone will fill up the hyd tank with gas on our wood chipper, the best part is that the hyd tank has a lock and is bolted shut, people take the bolt off and all to do this. Just amazes me and then they wonder why they are being charged for 15 gallons worth of hyd oil, where if they would have paid attention to where the gas tank is when we showed them initially it would not have been and issue. rant over!

for the record, it was a stupid move, (and i stood there and watched it happen) a combination of, working late, being tired, inexperience, and not paying attention. I am going to weld half chain links right by the hydraulic cap, and run a zip tie through it so that it doesn't happen again. hoping this doesn't become a $1000+ mistake, could be a hard lesson learned

Arm isnt in the way.

I was exausted from being up 36 hours, it was freezing, and had a million things to do that morning, machine was covered in a couple of inches of snow too.

Just wasn't thinking straight. Sh!t happens.
