Re: [z_scale] Gear Issue
- Have you tried swapping the gears? Since you have at least two identical
chassis, you therefore have four identical kingpins and four identical spur
gears. By mixing and matching, you may be able to more easily isolate the
problem. I find it hard to believe that the truck is misaligned,
especially to the degree that would cause a problem with the meshing of the
gears - besides, the truck is cast, not machined.
It sounds like you've cleaned the parts sufficiently; much more so than I
ever have, anyway. Perhaps the kingpin or the spur gear is bent, which
would also cause them to mesh improperly. If so, these parts are easily
So far, the only Marklin parts I've found to be misaligned in my own
experience are the rolling stock wheelsets, which is understandable, given
the mixture of plastic and metal.

I just did a swapping of the gears, and it appears to be the truck itself. On the 88571 the truck is plastic. At this point, I really do believe
that somehow, perhaps as it was cooling after manufacturing, it developed a slight bend to it? Not much of a guess but the gears and
pins all seem sound.
Since the gears function well in the other truck.....
I've had an really lousy bit of luck lately with gears! Still waiting for my 88861 gears as well.

fill the hole with putty and drill a new one, but that wouldn't be very strong.
Your best bet is a new truck.
With the tolerances as tight as they are in these things, it's a wonder it
doesn't happen more often.
If debugging is the process of removing bugs, then
programming must be the process of putting them in.
