I purchased a 37613 pair of PA-1's from Germany. The passage overseas was a little rough. The packaging could have been better.

When I removed the engines from the box, there was a small spring resting in the bottom of the box. Figured it came from inside the engine. this is a picture of it. It's about 5 to 7 mm long.

Spring37613.JPG I went through the manual that came with it but the only thing I saw was a tension spring the looked like it had a couple of loops on each end.

Does anyone have an idea of where this might of come from?

Part #69 is a spring for the coupling shaft at the rear of the locomotive. To determine if this is the part that has fallen out, manually shift the coupler from side to side. If it does not self guide itself back to the centre position, the spring is likely the one that fell out and needs to be reinserted.
The part is the same on both the powered and the dummy unit, so you will need to check both.

It's not blurred, just the forum has automatically enlarged it. If you actually click on the image you'll see it correct size

That doesn't look like a coupler centering spring to me. I looks too robust and it doesn't have the loops at each end for connecting.

There's always the possibility that it ended up in there by mistake and it doesn't even belong to that engine.

I see where cook_nz also replied and others have mentioned resizing can blur the picture.

As a test, I took several photos and selected the one that is the clearest. It's from a 12 MP smartphone. I then screen captured just the spring and part of a millimeter metric ruler. The spring is 5 mm long.

Clicking on the image brings up the way it looks on my monitor. That's about the best I can do.

I'll try moving the couplers and let you know the results.

Take a look at the parts diagram that is supplied in the box.
Look at #47, a small spring that allows the dummy truck to be spring cushion mounted.
The parts diagram is page 42 of 44 total pages.

Seeing the new image, I would have to concur that it is most likely the part 47. The exploded view diagram does not specifically show how this part is held in place.
There is a screw from the inside housing which goes into the metal top part of the bogie, with part 47 inserted above the middle of the 3 axles. The same part is used in the same position on the motor bogie too. Based on the diagram, I can't see how it would serve for suspension, but it might serve as a contact to the middle axle for electric purposes.

Based on this, you will have to inspect all 4 bogies until you find the one with the missing part.

The diagram has part 47 as a "druckfeder" which Google Translate has as a "pressure spring". Seems about right. ThumpUp

Yup. It does look like the spring and where it might go. Thanks! Guys!!

Now I've got to figure our how to approach this without messing up two nice engines!!
