This was originally writen in answer to another former fourm member but contains a lot of useful information uf your having problems with yours running right?

I have an MDC track cleaner that runs flawlessly for me and has for years with just the standard motor and gearing and does not run jerky, as you mentioned in a much earlier post, that your climax was doing. It runs with smooth steady power for me.
Now, contrarly the MDC Climax I picked up in kit form last year does run jerlky as well as having trouble negotiating various areas and turns if they're just slightly too tight.
I corrected the limited truck pivoting problem by using a fine round jewelers file and releived the outer edge of the journal connectors where the truck drive conector hits when the truck is pivoted completely to one side or the other. This made a big difference in a smother running mechanism in tight curves.
Also, ensure that the copper wipers are pressing against the contact screw heads firmly enough and that the wipers are also pushing against the insides of the drive wheels for good pickup.
Thats the only thing I did check last night as I was having problems with the Climax running without sometimes stalling on a 20" radius curve. As soon as I gave it a slight adjustment sidways off she went so I now realize it must be poor electrical pickup of the wheel wipers and I had just securely soldered feeder wires to the track almost right at the stall point too.
I'm going to ensure the truck wheel wipers are making good contact and I'll bet that will solve the problem. I usually bend the wheel wipers in a semi curve on the end to contact the inside of the wheels.
Also be sure to put a rounded bend on the end of the poortioin of the wiper that contacts the screw heads so they don't come in contact with the frame and short out.
