    pc75uu-2 swing gear oil question

    Hi everyone, I hope someone can shed some light on this. The manual is not super clear, but I assume that the zig/zag shaped dip stick right behind the boom is where the SAE30 oil goes for the swing gear,. I can't really tell from the stick what full is. The oil is so thin is doesn't really...

    What's this for on a Komatsu PC75-2UU?

    Yes it appears it was originally purple and you're probably right it is for the fuel bowl and it was just water/diesel from that mixing with the coolant in the pan that I was seeing on the ground. I've still got a coolant leak somewhere I can't easily see it I guess. I took the bolts off the...
