Leaking Dewald hydraulic pump

[Terry’s Atrium]

Hi, I have a 2005 Atrium diesel pusher with 3 slides. I have a Dewald hydraulic pump that operates the leveling jacks and 3 slide outs. The pump reservoir is leaking. I’ve looked at the power gear manual and have done some research and it looks like Dewald was purchased by Lippert. Before I go down a rabbit hole, I’m wondering if anyone has had to tackle this problem and either obtained a rebuild kit or replacement pump from Lippert? Or perhaps had the existing Dewald pump rebuilt?

Any assistance and info will be greatly appreciated.

Thank ou!
