The HP chamber is the same as the D2 80-90-inch lbs.

Note that with the D3, make sure the hex is seated firmly to avoid stripping the fitting!
Din housing parts are the same as the D1 – 225-230 for the Inlet and 150 for the locking screw

D3 Turret to body connection, no torque just tight with no movement, binding against thrust washer or visible gap.

Thanks @Jim Lapenta . I have a D1 manual revision dated 17 October 2017. It has 125 inch-lb rather than 150 still written on it. The test bench table also says 125. I must be missing the most recent manual then. Curious, I thought I was sent the correct link to Hog manuals last year.

And there it is, from the horse's mouth. Jim, you wrote the early manuals, didn't you?
I have no clue why 125 psi is in the current manual.

See, funny business and politics over informing the 100% people faithful

Yeah, @happy-diver , I have to be a little more circumspect with my advice these days, lol!
What I'd do on my own regs might not match the manual. Jes' sayin'

Dude the land of the free, the home of the brave, well the braves are gone, and you're not free, so it must just be
the home of the plain on the land somewhere

Now please try and understand I am refering to those living their lives crippled under possible threat of litigation
Not, by any means, a reference to ones, virility

Using the boot-pound method

Ohhhh I'm in the dark depths of Belize or one of those other places where the rich people go

Ohhhh my reg is leaking through the din thing Ohhhh who am I going to call rsingler

What about Jim Lapenta, "Who you gonna call, Reg Busters?" ha ha ha I really don't think so

What are those torque specs that I really don't understand how to implement anyway

I Know, we can fix it however we can with whatever we have like when diving and then just go diving

You will never ever know if you never have a go!

In that Belize with ALL those other rich people or one of those other places where the rich people go
