YES!!
no. snap it on and send it.

If it has tits, it's a liabilititty.
Use a hardened drive or there may be risk of it twisting and snapping off.
The gasket is optional. You also wipe a skin thin coat of rtv and just torque it down. Both are machined flat...
I agree.....but I've also always said if the gasket is there, use it. I agree too, the hardened shaft is a requirement for me with an HV pump.

Push the button, Max...
You can go either way, gasket or no. The factory didn't, but you can.
To me it's a possible failure point that, if it goes, can kill your engine.

Depends on which oil pan you're using.

Yes to both.
Never ran a hardened drive on any HV pump unless I was running thicker oils or if the engine was in a race car.
You got lucky. .......and not like on prom night.
i don't know man.... this seems like some boogie man or big foot situation.
everybody's fretting and hand wringing about spinning gear or snapping the end off, but i haven't seen any widespread accounts or pictures of such incidents.
stripped hex ends, sure. i've seen plenty. but straight failure, like in life, eludes me.
I tend to do what the oil pump companies say do. All of them I've seen say to run a hardened shaft with the HV pump, so I do it. As cheap as they are, it's kinda a no brainer.
i'm not a betting man... but i'd wager that they're all hardened to some degree...
too bad i don't have any spare shafts kicking around here, i'd take 'em for cute meet with the grinder and see what sparks fly.
It's not "just" the hardening. Here is a stock shaft VS a hardened HP shaft. Look at the transition where the shaft forms the hex. The smooth transition will always be stronger than a straight cut with a lathe. Look at the red circle. That's a "real" HP hardened shaft. Even some advertised as hardened don't have that smooth transition. That's a recipe for cracks to form under a heavy load. Use what you want. I ain't letting a hundred bucks at the most risk my build.
by golly, this is my first rodeo! is that dog with horns?! why are there clowns here?
well, i shouldn't make light of it. that was probably educational for those that didn't know the subtle nuances.
anyway you ever seen one broken, first hand account?
On a Ford, yes. Valve seals turn to broken hunks of plastic, fall into the oil pan and say hello to the oil pump, lock it down and snap the shaft. Seen it more than a few times. On a Mopar, no. But it's certainly happened. I can't fathom this is even an argument. Are you that frakkin cheap? Nevermind. I already know.
ah, so that'd be a no then.
from one dedicated cheapskate to another, i'll take that as a compliment. however i prefer the term: skinflint
Well sure. I said no on a Mopar. I'm a total skinflint. Just not a stupid one.
just checking, that was a "no" on seeing a failure on a mopar right?
....and I ain't calling you stupid, Buckwheat. I'm sayin I ain't a stupid skinflint.
