How do I get into a USA GP 38 headlight

I am sure that someone has done this but I would like to know how to get into the cabin section of the USA trains GP38 and remove the headlights and do a couple of other things to the cabin. In particular how is the removal of the floor in the cabin effected. I can see that the floor comes out but it appears to be jammed or is it glued in to place. Any help as usual is always welcome.

Grant,
You have to drop the carbody off of the frame first.
All the screws are recessed underneath, in real hard to get places, such as under the fuel tank and under the trucks. You need a #1 long Philips, preferable with a JS head.
I have done a few GP38’s sound conversions, but I don’t have one here now to give you exact instructions. I usually add another figure to the cab, so it is really easy once the body and cab are removed.
I know this prolly doesn’t help much, but it’s the best I can do right now.

Before you try to remove the floor from the cab, you need to undo the springs on both doors. Once you have the cab removed from the body and the battery boxes, you should be able to remove the cab interior from the cab shell. I had no problem removing the interior from the GP-38 that I worked on.

Grant, I don’t recall who posted this, or where. I own a GP38, so I kept a copy of it. Hope it helps you!

“Well got the early holiday a gift a brand new SP GP38-2 from USA Trains, via a local dealer. The engine required some addons and so this is where the sound system came in. The engine out of the box was flawless, though I would have preferred the older lettering to the Speedo Lettering on the engine. But why whine right, so I got that baby out of the box, unwrapped it and began surgery with a #1 Phillips. The fuel tank must first be removed, and there are only two screws holding it in place. Once those were off, the cover easily comes off. Surprise!!! They have a wire taped on the bottom awaiting your sound system. In this case the Techs at Phoenix have the most pleasant voices so I got their sound system again. Installing it, I opted to go the non trigger method and stick simply with the track voltage rather than sensors. Wise Move! The speaker with Phoenix sound systems has 4 screw holes, but the GP only has 3 in a triangled layout. So a little bit of glur to the rescue on the edges, what would I do without a bottle of Zap. Glued it, hit it with the stiffener spray, task done, speaker installed. Next was the volume switch. This required installing a drill bit sized 1/4 inch. I wisely chose the back of the fuel tank offset of the buttons and higher up. Than came the board. First I got the speaker in place than the volume control and finally the power wires from the engine. Remember that when doing the wires with the Phoenix connector plug. Red goes in number one and Green in number two. Nailed that and finally stuck the double-stick tape on the back board, than mounted the board inside the front tank wall. You will have to carefully bend up the speaker wire attachment end leads to squeeze and mount the battery between the speaker and the board with the other two double-stick tape squares that Phoenix supplied. Once that was accomplished plugged the battery in and I buttoned it up. I generally leave the computer plug off and I am not a big sensor fan as with the voltage determining sounds on a diesel it is much simpler and you can pull sound fx by shifting the voltage up or down on the transformer. Next were the wheels. I HATE traction tires, they even smell horrible too. So that means the wheels were next. I got two pairs of the F3 wheels in a bag from the dealer as the gp wheels and f unit wheels are the same.”

“Took the gear box cover off, 6 screws and it pries off, no problem. Took the two end truck side screws off and pried gently the wheel out of place. Than got the solid wheel with no traction tires and got it in place. A little extra grease for the ends of the axle and those babies slipped into the journals with no problems. There is a small squared gold seat on the axles between the gear and the wheel. You must seat this flush and even in the block or you will never get it to work right. Repeated this procedure on the other motor block and plenty of grease and than buttoned them up, well not quite. I also HATE pickup shoes so all four as usual had to go, and go they did, than I buttoned that sucker up. Those were all the easy parts. Now came the Dallee Dual Mars Light. What would a SP engine be without a Dual Mars Light…right?”

“Okay getting the screws off, I learned a lesson from the half burning GP30 which I corrected This time I cut the L.E.D.'s from the ceiling board and removed the cab only. Once the cab was off I went to work on carefully getting the ceiling of the cab off. Cut the Dallee leads and did the wire routine which by the way is a major pain in my Coal Burner! Got the LED’s in place and finally I soldered the leads to the old led mounts on the board. The Dallee board has stick-em tape. I decide to stick in on the ceiling. Once done, I got back to assembling this and it worked pretty well as far as the reassembly went.”

“With all of this work done, the time had come so out went the ol’ Bridgeworx and hooked it up to the outdoor layout. On the bottom of the GP38-2 are four switches. The smoke unit off, left that way. Honestly with Diesels I never use smoke. Motor is always shipped on so that was a no brainer. Than there are the lights and the sound. Those on. Got the engine on the layout. Turned the power on and crossed my fingers.”

“PROTOTYPE here we come. Everything but a snowplow as most SP’s had them by default, but not USA or Aristo. So went ahead and throttled it up. Sound comes on turbos kick in, loud too, enough to bug a few bad neighbors (pun) and than no pickup shoes. I had to use some old LGB brass which was not well cleaned. But the USA wheels without the pickup boots worked flawlessly, and I really do mean that as to where my old LGB lococ would be very jerky at many places, the USA pickup is far superior. I guess that is why LGB is OOB…you figure that one out. Metal wheels I hooked up 25 cars and no problems the engine handled them without traction tires. Than I noticed something. Ah the Lars lights, they worked and they worked very well. No more shorts like a issue in my GP30 a while back which I ended up fixing. Man seeing those mars lights blink was very cool indeed. My only complaint is that Dallee needs to make them blink a bit faster. Perhaps if they can view some train videos they can time them from there. Well with all of this nailed down, it was time to pack everything away. Just as I put away the last of my Sunday railroad stuff, someone walked in with a new holiday gift for me, a USA SP-GP9 and let me tell you with the vintage “Black Widow” paint scheme, and that was no plain bergie.”

Gentlemen.
Thank you for your help. After reading these posts I had that unit in bits in about 10 minutes flat. now I can get on with installing LED’s for headlights and making a couple of tiny little changes to the lighting else where. Mainly for current saving on the batteries. The USA lighting really does draw some amperage. Again many thanks to you all.

Everything on a USA Trains engine draws a lot of amperage!!

But they do run damn good and tough!@
