Watching the forum for a while, great resource. I have a few mfx all running on a mobile two. My 95.9 is the only noisy one and only in one direction. I have lubricated it at the points on the underside, tried reversing the center pick up as well, even tilting it a bit since it seems directional (plastic on one edge). All to no avail. It's a slight clicking, sounded to me like the gears meshing? And it's totally smooth in the opposite direction. I tried removing the four screws in the exploded diagram on the underside (part 13) but the bottom plate wouldn't come loose and I didn't want to force it. How does it come loose ? I'm thinking i need to get to the motor am I wrong? Any thouhts welcome.
Thanks again

Thank you!!! I notice the slider has one end with a plastic leading edge. I won't touch that end but will try to put a slight arc in the center. Other end has the std curve to it to keep from catching. The engine runs great other than the click in one direction, and its well oiled at this point lol. So maybe that's not the cause. I Tried reversing the pick up is there a preserved direction for the vt95.9????? Thanks again!!!

I would suggest you loosen the screws on the motor brush plate and see if moving that around, making sure it is seated properly, makes any difference. I don't know if this is a work drive loco, so don't know if you will be able to rotate the motor by rotating the wheels. If you do go this route take the brushes out first.

Well i was able to open it up. I checked page 34 of the manual good summary to open it up. There was some grease but i added a bit. With the passenger floor off the motor is loose in vertical and a bit horizontal. The passenger floor acts as the upper motor mount. The Floor and the four main screws around the floor hold the motor in place. I tried slow running it wo the floor and the sound came on in one direction as the motor hopped off the gear, clearly not meshing ideally. I assume this is the case as its the same sound with the floor back on. I tried it "as is" w grease and floor snugged, same sound. Tried adding a small bit of rubber above the motor between the floor and upper of the motor same sound. Reverse is still silent but forward is the "clackity of the gears" alas... Ill just have to think of it clicking along the tracks w sound off. It may be a touch quieter going over a switch but not sure how's that plays into the equation. I took some pics but not sure how to load them. May not be of use since I couldn't quiet it. Thanks again to all

Lol quite true. It is an otherwise nice model. I did notice that while my mobile control 2 was set to set "stop" on more than one occasion it didn't see the VT when I placed it back on the track. It need a power down. I have about 10 engines all parked but live. I have had one full reset event I don't know what caused it but all of my running engines are mfx so not brutal as it found them all. I had to reset many sub parameters. But I can't say if it was the VT. I emailed Marklin day of my last post but haven't heard back. Should they be emailed in German or English. Better luck with one or the other???As for the VT I now just run it with driver facing the trailer.
