About three or four years ago I pressed buy on impulse on Ebay for a brand new Norwegian Shunter 36334 on a BW Bahn Saturday promotion/auction. If fitted with nothing I already had but I would make the following statement to the jury 1) it looked nice 2) it was cheap and very good against the list price 3) its digital function were limited to lights but when your as deaf as me that hardly matters.

It arrived and a new item had also arrived from MSL so it got little attention. The few times I operated it it seemed a little "stiff". During lock down boredom I tried it out on the layout and it hardly moved. A light oiling per manual did nothing to improve matters. the manual appears not to want you to go further and take the body off.

Any suggestions or experience with this little fella?

I have a 36334 that works ok. I searched a Norwegian forum for this problem. It seems to be a well known one on this model. Two metal clamps that are holding the engine together are a little bit too tight. Release the tension a little seems to help. (It is not the two black plastic clamps that are holding the engine in posistion.)

It is correct that this model comes from the factory with very limited light functions. The only light function is shunting signal with marker lights front and rear on (aux1 and aux2). However, you can program other functions too. Light forward and light backward have another intesity than aux1 and aux2. Aux3 and Aux4 is connected to a PCB with red lights in the top of the drivers cab. The red marker light in the drivers cab is not prototypical correct in Norway. One day I will try to swap them with yellow ones (or even better - all the lights warmwhite). Then it will be possible to give the correct tripple A signal for line duty as well as shunting signal.

I opened up my 36334 and compared with the description on http://forum.mjf.no/



It must be the two metal clamps in red circle that it refers to that can be adjusted briefly to make the engine run better if they are too tight.



It is only the two black plastic pieces that are holding the engine in posistion. I would check if the gears are alligned properly and remove the engine to see if it moves around freely - eventually adjust the clamps briefly if it doesn't.
