Hi guys, how do I know the capacity of my Hydraulic pump? I have three choices. 6.5GPM, 13GPM or 23.5GPM.

I think I found it. 13.5 GPM AR103033.

I see you already found it.
6.5gpm was without power steering
13gpm was with power steering
23.5gpm was an option, which I doubt not very many, if any had.

Thank you for the information. Mine is a power steering model. Good nugget.

Are you positive 6.5 gpm pump wasn't utilized on earlier models below serial # 045,200 that could have open center power steering?

There is a pre serial number range consideration for the pump. Mine is a later model.

I went by the serial number he posted

Sorry I misunderstood your reply. I thought you were referring to all yr models.
