In the past, "somebody" (I can find the thread no more) proposed to send me a picture how to disassemble a Budd (old generation, NH). And could it damage anything if I put some "contact spray" (with a brush) on the outer sides of the wheels, where the wipers make contact ?

There are a couple things to be aware of. The trucks have a tongue that slips into the shell (#1 below, but best seen in the exploded view above). You'll need to work the shell over these for removal and reassembly.
Each truck also has a drive shaft (#2 above). These are easy to lose and as far as I know impossible to replace. I tie a thread to these to keep from losing them. The ends are actually very tiny gears and for reassembly I first work them into the motor nest then the trucks. You'll probably have to move the wheels a bit to get it to engage. If the shaft isn't engaged right the trucks won't install right.
There are no wheel 'wipers'. The axle points ride in a 'dimple" (indent) in the metal strip. Use a tip of a sharp object to place the tinyist, smallest drop where you cannot easily get too - the tip of the axle.
First, I don't have a correct contact on one truck, it seems intermitent ; because my system uses a detection of current at the front truck to stop the train, the Budd's (they are used pairwise) run too far with the "problem" truck in front (up to 7 cm) ; second, sometimes the same Budd stalls, and the other one begins slipping ; and this can occur even with the front lights at the "problem" Budd lit ... I must admit that in my room it was not really warm for these tests, so I wonder if there could be some "grease" which is too "thick", because the second one has no issues in the same conditions ... I already sent it back to the German distributor, he says that it has been running without any issues for several days on a test oval (I think at room temperature, this consolidates me in the idea that the problem is temperature related, but how to solve it ? ), so the main problem remaining could be the pickups ...
