Door question

[reaperman1]

Ok guys, try and follow me here. I have an ongoing issue with my Boxer door sagging to one side. The Boxer has a large door that is 28" long x 14" tall and weighs exactly 25lbs (according to my luggage scale). So its rather big and heavy. The constant sag causes the knife part of the stove that comes in contact with the door gasket from being centered.

My theory as to why the door has an issue staying level can perhaps be explained by the hinge pins. There are only 2 hinges on the door, top and bottom. As shown in one of the photos is the threaded OEM pin. The pin or round part, is exactly 1/2" long. Here is the reason I think the round pin itself is too short for the door hinges. The loop on the door and on the stove itself are exactly 1/4" thick. Together, the two loops combined are 1/2" and are mated together by the hinge pin.

Now when you subtract the height of the two washers used on the hinge system. The thicker washer on the of the top of the loop and the other washer in the center where the two loops join together. Your subtracting that much pin length away from what goes into the bottom hinge loop. This loop is the one welded onto the stove. To me, the round part should extend the entire distance to the bottom of the hinge loop. The way it presently is, it only sits half way into the loop. Being there are only these two short hinges that hold the door, I think it would hold better if the pins extended the full length of the hinge rather than only half way into the lower hinge section.

Keeping the hinges tight with the bottom nut it hit or miss. When you tighten a nut it tightens everything. So the door opens hard because it doesnt slide easily on the washers due to everything being tight. And keeping the door tight only works for a short amount of time because the nut will work itself loose and the door sags once again. Am I on the right track here or way off? I've never saw any kind of hinge pin that didnt run the entire lenght of the hinge itself. One photo below shows just how little the pin will is left to drop into the bottom loop compared to the upper loop. Plus a thin washer still needs to be inserted between the two.
