Hello, hope all is well. Welcome to the forum. I guess it is a possibility your seller did not know much about this item. Hope you got a bargain.

This model was among the first Marklin z scale produced and was sold as number 8800/8805. It was sold in millions of Marklin starter sets and was advertised extensively to announce this new scale to the world. (The was in 1972) This is known as a tank locomotive which has water tanks on each side of the boiler and is highlighted be the fact it has its own coal onboard. No tender required. Your model when working properly, is very reliable and able to pull an impressive number of wagons. I often have said it pulls more than you would expect. Surprisingly heavy, the weight is centered right over the drive wheels. Though originally a three pole motor, this model was update to a five pole, perhaps in the 90s. It is a very good locomotive for the beginner and a true symbol of the Marklin z scale hobby. It is a Br 89 and is out of production currently. It was replaced by the Br 80, but it is possible this one is out of production too.

Do you know if the armature is a three pole or a five pole? Three pole brushes are 8987 five pole are 89871.

Unfortunately, this locomotive uses the actual frame as a housing for the armature and not easily serviced or replaced. Because they are so reliable, and seldom seriously damaged, it is possible it only needs to be cleaned, oiled, and the brushes replaced. If a three poles, it should still perform well. Just clean it up and it will probably be okay. If you decide to do this yourself just be careful, the parts are small and easily lost. The coupler spring is famous for being hard to find. Search this forum for assistance with quartering the wheels and cleaning tips.

Here is a link to the Marklin parts diagram for this one:

Again welcome to this great hobby. Take good care.

Hello, hope all is well.

You are right, if the armature is going to be removed, you need a small puller. I have not done this myself, but I have read about it here, that it is easier to just cut it off.

Since you know it is a three pole, I would mention, any of the brushes will work. If it was a five pole, don’t used 8987. If you need the armature kit, I think www.zscalehobo.com has them, in fact Frank could possibly do the work for you.

I bet you will have this small locomotive working in no time. It will surprise you.

Take good care.

If you are new to Marklin Z you may be unaware of "HOS" or "hardened oil syndrome" caused because the oil Marklin used long ago would congeal and clog the works. If your brushes are still in decent shape then I would suspect a good cleaning and maybe needing a toothpick, brush, etc will do the job. Be careful as some solvents will attack the paint. If the brushes are worn away then the loco was well used and it may not be HOS, just worn out. As pointed out above, if anyone could get it running it would be the Zscalehobo.com

Marklin oil just goes to solid wax. No loco will move, forwards or backwards.

I use lighter fuel to clean locos, usually pull to pieces & put one bogie at a time (to make sure they go back on the correct end) in a container & shake. Then dry parts on paper towel / evaporate.

Make sure electricity is off. Lighter fuel is just clean petrol with the same catastrophic results if not careful.

Re-oil with Faller 170489 oil. Use it sparingly, don't over oil.

Labelle 108 is another popular oil for these little engines and may be easier to get here in the US.
