I bought a marklin steam locomotive where the wheels are frozen up or not moving at all. Any help ? Ho can repair it. Thanks

HO gage track and a HO compliant controller. Any hobby shop can sell you the correct parts.

remove screw that attaches the side rod to the drive wheel, place traction tire in groove in drive wheel, replace side rod & screw.

Try cleaning the track AND wheels with an INK ERASER. Put the engine on the track and help it along. It could just be tight from sitting in the box. I live about 8 miles from the Strasburg railroad and have 2 relatives working there. We have ALL experienced the same thing on4 different sets. It isn't just the Strasburg sets that do this, it's most of the new toys. Your Strasburg cars might not connect to other train sets. Their car couplings are different, just like on their real trains.

Proto 1000 and 2000 trains used defective gears between the axles. I just replaced a bunch of them on mine. Find some Athearn SD 40 gears, which are exactly the same, to use as replacements (I got mine from a seller on Amazon for cheap). Get a small screw driver and pry off the bottom of the truck (it will be a long narrow black plastic piece). Pull out the wheelsets and you will most likely see small crack in the gear. Pull the wheels out and discard the gear. Take the new gear and insert the wheels (they go in really hard, so you have to use some force -- I used two pairs of channel lock pliers to get this done). Use a wheel gauge to get your wheels right and then put them back in (you have to line up the little square nuts so they drop in right). Replace the plastic clip on the truck and you are ready to go. This should eliminate your problems.

need the instructions manual for crane 7051

I need the instructions manual for crane 7051 Marklin. Thanks

Probably the springs of the inverter unit are broken or too old. If you replace them by new Marklin springs, it shoud work. Notice that they must be the correct Marklin springs: any other springd probably won't work because their tension is not the correct one.
Best!

Hope you got the set working. If not, look underneath the locomotive near the rear (under the "cabin"). There are two switches, one on either side. One says "Smoke", the other says "Reverse". If the "Reverse" switch was set to "Off" when the locomotive was in Neutral, it will stay in neutral even when the power is cycled or the "Direction" button is pressed on the power supply. Even in Neutral, all the lights will work and I believe the smoke element will heat up but won't puff. Whatever setting the "Reverse" switch is on, try changing it to se if that works. Hope this helps...

You may want to try at this site: http://www.marklin.com/tech/ It is a tech page for Marklin products. I did not dig into the page but it looked like it may have something to help you.
Good luck.

found your couplers and wheels.
