Star Dreamer Posted July 25, 2017 Report Share Posted July 25, 2017 Have you ever thought of using a Hollo-Bolt for the fastenings to the tubes? They are made for structural applications to tube steel. It would eliminate the sleeves in the tubes and only need holes in one side. I am not sure if they are available in the Grade 8 though.

ALLOY Posted July 25, 2017 Report Share Posted July 25, 2017 By no means do I understand all the dynamic but when I look at the connection to the frame it looks like a pivot that will (for lack of knowing a better term) twist the bolts holding the hitch to the angle. The bolts would see less twist if the long horizontal pieces of angle was on the opposite side of the HSS from the frame bolts or there was a piece of angle on both side of the HSS at the connection (8 bolts instead of 4) to the frame. 2011 Cameo 34SB3 Link to comment Share on other sites More sharing options...

JT, think of the 1/2" bottom plate as a diaphragm plate with the tube, ET frame and angle acting as a stiffener to prevent out of plane buckling. What you have is a single sided connection angle which would not be OK in my world due to AISC connection guidelines (take a look at the PDF link that I posted for my suggestion) but would work engineering wise. For any engineering problem, you can have a LOT of solutions, all of them will work but some will be better than others depending on shop time and equipment. I just happen to avoid a single bolt connection for anything unless I don't have any other options. 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...

Drive on .......(forget the bolts.....I vote stainless 321 upset rivets hole-filling in six-d-spacing-five-rows...... drawings to be issued shortly.....standby....) Yes Dolly, OVERBUILDING, has been my mantra since I started playing with things "heavy" such as fifths, HDTs, hitches and heads. One sleeps better at night and the few extra (or even extra, extra) pounds of steel doesn't make a diddly difference. This kind of thinking is diametrically opposed to machines and products that take flight, but that is a totally different world, different engineering and most definitely different price point for products offered in that world. I agree wholeheartedly that for any engineering "challenge" there will be as many solutions as the number of engineers looking at it. And some of these engineers (usually old goats) might even "conceive", twins, triplets, or quadruplets. I am utilizing a methafor, here, speaking about ideas only, not a result of young billy goats pursuing yews in heat. Although, this old goat is still interested in occasionally casting a sideways glance at a yew, he has more time to study esoteric things such as 150 ksi, grade 8 bolts in shear and tension. For the benefit of the younger (still yew chasing) generation, 3/4" bolt is 53,000 pounds in tension and 40,000 pounds in shear, there will be 4 of them in shear in this "solution" for a total of 160,000 pounds. I would venture it's OVERBUILT AND OVER-DESIGNED. The 5/8" bolt is 36,000 pounds in tension and 28,000 pound in shear, there will be four of them in shear for a 112,000 pounds and 8 of them in tension for 288,000 pounds, although alternately (depending whether the forces are generated by pulling away or stopping) either front or rear tube will be compressing against the angle taking the tension away in that area. Having observed and measured actual forces pulling fifths with a strain gauge instrumented king pin, we observed 1/8 G on takeoffs and 1/2 G on stopping (with the trailer brakes disabled) and that was being as aggressive as we dared to be doing it. This translates on 20,000 pound trailer to about 2,500 pounds pull on the hitch taking off and to 10,000 pounds push on the hitch stopping. Of course these numbers are out the window if you go in the ditch or lay the trailer on the side. Link to comment Share on other sites More sharing options...

You brought up a situation that I weigh every time I consider letting someone else "touch my equipment". Will they use my wallet to change out parts until it appears to be fixed? Will they screw something else up that I won't come across until later? Will they even put all the fasteners back in? Will they torque things correctly? Will there be damage to the vehicle with the famous " I didn't do it....it was that way when it came in" Or will they charge 10x what the job is worth, hoping I agree to a free muffler bearing repack. In almost every case, I can't deal with the collateral damage or wallet rape, and do the work myself, even if I have never done the job before. On the up side, it is apparent there is one good diesel mechanic (that also does hitches) in Florida that I would trust if I had a problem 2009 Volvo 780 D16 535hp 1850 ft-lbs I shift 3.36 Thermo King Tripac APU DIY Bed and Frame Extension ET Hitch, Stellar EC2000, EcoGen 6K 2002 F350 CC Dually w/ Lance 1181 2012 Mini Cooper S 2007 Teton Royal Freedom " The only place you will find success before work is the dictionary " Link to comment Share on other sites More sharing options...
phoenix2013 Posted August 14, 2017 Author Report Share Posted August 14, 2017 I have two mechanics pondering this "situation". One very good friend of mine (we've known each other for years) who used to teach diesel technology at a junior college in New Hampshire. Not just theory, they would take clunkers from local businesses and a year or two later deliver zero time truck. The other is a local diesel mechanic and his primary clientele is boat owners. So working on a truck in a garage is a "luxury" for him. He had the engine stripped right down to pistons in eight hours and the bottom off and the pistons and liners out in about three. Not his first rodeo. Link to comment Share on other sites More sharing options...

But, it runs far better than when I took it in....
