Ok thanks. I read through most all of the TMs a while back but i did skip some spots I didn't feel applied to me. Water fording probably being one of those as I don't recall it. Around here if you get to water you already went through a ton of trees and then down steep banks... There wasn't a lot of oil but will keep an eye on the air tanks. Thank you for the help.
Sounds like the previous owner hadn't drained the air tanks like they should have. Both tanks are supposed to be drained every time the truck is driven because of oil and water accumulation, which is normal. A lot of oil could indicate a problem, but you won't know that until you get the truck up and running and drive it for awhile.
Yes. The plug you see is stored in a blank hole and is moved to the open hole before fording deep water. After fording, it's to be removed from the open hole and put back in the blank storage hole.
All the above info is in the TM.
