I have a 2006 B3030 with a LA403 . It’s leaking oil from the control valve . Any chance others have experienced this problem?

Could you be a little more specific about WHERE the leak is? There are multiple lines, connectors, fittings all over that thing. Is it one of those or what? Take and share a picture of it you can.

You may need to replace one or .ore seals on the spools. A little fuller description of exactly where its leaking would be helpful.

Thanks, I’ll have to try to identify exactly where it is leaking from. All I know right now it’s dripping from the low point of the valve block assembly.
