Contaminated hydraulic oil

[Johnherbert]

I have some milky hydraulic oil that needs changing. How do I flush all the oil from the lines that go right to the grapple on my crane ?

its probably just milky where its met the water. Drain resevoir down  and clean out. It'll flush through when you add fresh. Change filter also.

 

 Other than that you'd have to disconnect at the actuators, let it out and then just carefully bleed it afterwards. Unless its milky through out i just do the reservoir bit.

Thanks for that. Would certainly save a lot of hassle that way ?

Yep as always, basic maintenance first then if it raises any doubts go a stage deeper.
