Unlike modern machines and vehicles where every bolt has a torque spec, older items really don't.  I have big tractor manuals that just say to tighten sufficently or similar even on items I would like to Know a torque on.  I have never torqued a pto myself, just tighten it up snug. Should have a lock-washer on it too. The pto has a sleeve/spacer like item between the pto parts and the shaft of engine that you are torqueing on and it won't crush the pto with those parts. Should be spacer, big flat washer, lock washer, then bolt.  OR, there are charts for torque for diff size bolts used somewhere that give the max torque for each size and thread type. This may not apply to this set-up tho, as you won't need the Max torque used on that bolt.
