Question Issue with Hog D1X DIN locking screw undoing itself

[Jim Lapenta]

These are the test specs from the class I taught through 2022 when I retired.​

UPDATED Test Bench Specifications 9/29/2019​

Test Range
Intermediate pressure 135 psi, +/- 5psi
Intermediate pressure creep: No more than 5 psi in 15 seconds
Cracking pressure 1.0 – 1.2 with adjustment knob fully open
Closing the adjustment knob will add approximately 1.0

Vacuum leak test 1. No leaks allowed
Bubble leak test 1. No leaks allowed

Torque Specifications
Part Description Torque
D1, D2, D3 DIN Inlet 225-230 inch pounds
DIN Locking Screw 150 inch pounds

HP Port Plug, LP Port Plug 35-40 inch pounds

Turret Bolt 120 - inch pounds
5th Port replacing turret bolt 170 - inch pounds

D2 and D3

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.

Yoke nut 225 - inch lbs.

NANO and EXP Yoke Nut 150 inch lbs.

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

125 is not in the manual I taught from or handed out. Every student got a print copy of the D1, D2, and D3 manuals along with the second stage manual.
I printed them myself and put them in a binder with laminated schematics of the stages.

I did not write the early D1 Manual. That was someone else.

What happened after I became a dealer and instructor was some back and forth with the factory because of that loosening DIN retainer issue, so that got addressed.

That got sorted out more when I did the drafts for the D2 and D3. Then the D1 was updated. Instructors should have been given the new specs, but that was also kind of hit or miss.

Also, when Jack came on, he started requiring instructors to send students' emails to him so that they could be added to the Dropbox account. All the manuals were there, along with any updates that came out to specs, tips for certain procedures, etc.

I don't think that even exists anymore. I used to have a link, but it no longer works.

The problem was that instructors were issuing certs but not sending their student info, and people were unaware of that support option.

The other problem was that some instructors were only covering one reg. The D1. So if they had an old version of the manual, they had the old specs. Had they bothered to cover the D2 and D3 like HOG wanted them to, they'd have seen the update.

I always covered all 3. I always had an example of each and broke each one down to show the differences. And the student would get to rebuild my reg if they didn't have a D2 or D3 of their own.

When I did the course there was somewhere in the TDI/Hog material that said that you only got certified for the regulator model that you owned. I don't remember where that was written specifically, i'd have to check my notes, but I do remember it was stated explicitly. So my instructor didn't 'not bother', he followed those guidelines and only taught me the D1X. He offered to teach me about the D2 and D3 for free afterwards if I ended up purchasing them at some point. I got sent a Dropbox link, which still has the 2017 manual (plus the manuals of every other Hog/edge reg), from where I got the screenshot earlier in this post. From my point of view it seems like an issue directly from Hog. I've even emailed Hog before a couple of times and they never reply to me...

Me too. Never could get newer manuals through official sources. Thank goodness for ScubaBoard.
