Joined: 07/06/2013(UTC) Posts: 424 Location: Florida		Back 30 years ago when I was visiting Ottawa in Ontario, Canada, I was offered a box with some Marklin trains in it. The only thing that caught my eye was an SK800 with the tender. I purchased it on the spot and brought it back with me to Florida. I saw that it had a bent axle on the front driver wheel set, so I never ran it. Well it is time to bite the bullet and repair it. It will entail removal of the running gear from both sides, removal of the wheel on the non-bent side then removal of the wheel on the bent end of the axle. Then comes the fun part, straightening the axle and re-assembly. It might be easier for me to just purchase or make a replacement axle. Can anyone recommend a supplier? In any case the lok is on the workbench and will get dismantled today. In the picture you may notice that on the right side, the piston rod and connecting rod are missing. These were most likely damaged when the axle was bent, the lok was probably dropped by the original owner. Here's a few pictures. mb300e4m attached the following image(s):

It just happens that the axle is exactly 2.5 mm thickness which by pure coincidence is the same as many of my older Trix Express lok axles. When re-wheeling older Trix Express, I used to try and re-use the original axles, but so often they would be damaged during the change process so I started making my own replacements using 2.5 mm drill rod. Thank goodness the Marklin axles do not appear to be splined and should just be push fit. Here is a picture of the injured one. mb300e4m attached the following image(s):

I found there may be folks on this list with replacement parts and you could get a personal mail from one of them. ebay Germany has some axles on it now. Ritter and the ttn-shop also carry replacement parts. If you don't see what you need listed, you can always email and ask, because they do restorations and repairs. see links: http://www.ritter-restau...y=1.3.9;artID=6543;typ=1 http://www.ttn-shop.com/...&lang=de&spur=H0 Your SK 800 is in very nice shape otherwise and keep us posted on your progress!

Thanks for the links Seatrains. I have straightened the axle and now that wheel runs truer than all the others. Next comes re-assembly. I will search my parts for the missing rods, although the lok looks OK without them, at least the uninitiated will most likely not notice because of the shroud. I will post some more pictures in a while. Peter B.

I have one very similar to it except that it is a later version (probably from an F 800) , with a slightly different crosshead slider (Who cares? It's not visible anyway!! ) Also has the valve gear connecting rod attached, but it is easy to pop the rivet that holds it to the crosshead. After you do that, it is fully usable on port or starboard (left of right side) If the right size, and you can live with a different crosshead style it's yours!(I'll even pop that rivet for you! ) Cheers jvuye attached the following image(s):

Sometimes people on this forum can help and have the spare parts that you need. Neil. Hello Neil, I was a bit concerned about the condition of the wheel, but the only damage was to the flange which was a bit wonky. With the wheel in the vice, I gave it a few taps using a drift and a tiny hammer and it was fixed. It was fortunate that the wheel was not broken, fractured or bent. I omitted to take a picture of the setup I used to straighten the axle, silly me. Peter B.

The same size as the one in your picture. The SK800 has separate valve linkage and is not connected to the crosshead. Thanks for your very kind offer. Do let me know the price and cost of postage and I will be happy to send you some lolly via PayPal, no fees either. Best regards, Peter B.

Joined: 07/06/2013(UTC) Posts: 424 Location: Florida		I recently received a set of rods all the way from France, for which I owe a BIG thank you to one of our members. They have been installed and all is now well. The next time I have the portable layout installed, I will shoot some video and post it here. Thanks also to all the members who offered suggestions and help. Here is a picture of the completed project. Peter B. mb300e4m attached the following image(s):
