Motor offset hangs below centerline. Attached is Compactor manual. Page 66 breaks down the valve.

It's a fixed displacement motor, there's a relief under the attaching bracket , follow hoses off motor. Super simple
I know that, it has CASAPPA KAPPA 30-32 in it.
There’s also supposed to be flow control valve, and I know for sure there’s a check valve and supposed to be anti cavitation valve. I need to know weather it has cross relief also.

Motor offset hangs below centerline. Attach is C6B diagram. Damned near identical, just bigger.

Thanks! unfortunately I need more then that.
And B series is different then C series. C series has its own relief, the question is it one way cross relief or two ways?
This thing works with hydrostatic pump on pile driving barge, so it is little different then regular backhoe or excavator set up.

I keep forgetting that I put the flow control manifold into all of my B series compactors. I've got C4B, C6B, C6C, & C8B compactors in service.
