D7 17 A restoration

Hi, Ali.
That sounds like a good plan to me. If it is done in a tradesman-like manner, the materials that you mentioned should support the D7 frame and engine. The only suggestion that I would offer would be to provide some means of stopping the frame from sliding sideways on the top beam. You could perhaps weld some 1/2" plate vertically on the ends of your top support beam rising a couple of inches above the top of the beam to stop any chance of the frame sliding sideways off the support. It might be embarrassing - or even dangerous - if that happened

It would also help in this regard to screw or bolt a GOOD piece of 1" thick hardwood to the top of the top beam, making sure that the vertical plates on the ends are still protruding above the timber.

Just my 0.02.

in last few day I built the stand , the post are 4 in diam 1/4 in steel, the top bar 4x4 1/4 in steel .
next i will post pictures

Here is the picture of the stand , it is a monster, may be over kill, but will be safe

it span exactly the width of the D7 front Noze which is 41 in from outside of post to post.
There is a couple thing to be done yet, 1 is to add as Deas suggest an end stopper and flat piece of wood on top.

Hi, Ali Sleiman.
I'm no expert but I think your D7 should be able to rest its chin on that stand quite safely. Maybe overkill as you said but better that than waking up find that your 'beloved' has fallen down on top of you.

Just my 0.02.

Deas thank you for the support , the D7 total weight is near 27000 lbs , this will only support the front end.
yes we do not it too have fallen and specially on on me.

Always look a the worst that can happen,and add more support.Uncle was putting new under carriage on his HD21,had track frames off well supported on wood planks but it was out side and we had a real wet spell which allowed it to sink until it lay on its side.It didn't hurt anyone but was major job getting it back to upright again.So if your not working inside I would make the base bigger. Hope all goes well for you.

Looks like a good strong fab job. If any dought on rolling forward or back when both frames are under weld in an X brace or two from front to back to tie the two stands togather as one stiff unit. Good luck on your reassembly and keep us posted.

Looks good. In my option, it’s better to be little “Over Kill” than under. I would go along with old-iron-habit's suggesting to tie the two stands together. ….if one end moves the other one will come along as well, better to be together than spread out if for some reason it becomes unbalanced. Just my thoughts. But at any rate play it safe.

Today my sone & i were able to jack the machine from the old sagging wood and put the stand on the front of the machine [attachment=18166]D7 Front stand support deployed1.jpg[/attachment][attachment=18167]D7 Front stand support deployed 2.jpg[/attachment]
I agree with you old iron and kelly,
Now the stand it is place , my plan now is to put on ends of the top bar a peice of 3/8 angle iron to keep from shifting side to side . and to the bracing as you suggeted for more support for forward and back support.
