Kubota D972

[WA221]

I bought a excavator. It's a Komatsu brand w mostly Kubota engine and I suspect Hydraulic pump. But, I can't seem to locate any information to assist me. Today, I pulled the motor and hydraulic pump, as one. Uncertain of how these bolt up . any feedback will be welcomed tia

Is this a gasoline or LP engine?
