Oil pump intermediate shaft breaking

How much pressure is the pump putting out,,,,,unless it’s over a 100 pounds , you shouldn’t be able to break a shaft,,,not a good one .

Is this a fresh build, or a running engine.
You wouldn't believe the debris that'll come outta a used pickup while banging it on side of the solvent tank when cleaning .

A little background will help .
This is a fresh build, pick up is used but CLEANED through and through. New bushing, oil pump, etc.
