To lower height of fuel tank and chassis i separated hood from frame, snipped all wiring in order to properly handle the frame. I removed both trucks and fuel tank.
Looking at each truck; you'll see a shim sitting across the top of each, the bolster pin on the frame goes in the holes on shim.
I filed each shim down as much as possible, keeping in mind that the shims should have some rigidity for balance.
I used an Emory board for the sanding.
For fuel tank i laid two wood coffee stirrers lengthwise inside; one on left, one on right side and glued in place with a tiny dot of super glue gel.
Both trucks and fuel tank replaced; of note that air tanks restrict maximum lowering of hood due to radial swing of trucks.
This procedure took approx. 3 hours;
My alco demo#2 looks fantastic, the tank rides exactly right and the height issue has been reduced to a practical minimum.
I am an avid HO modeler, I've been working with trains since 1973
