I’ve repaired a few Aristo 0-4-0’s split gear plastic bushing thingies on the drive axles. This is just plain old EXTREMELY bad desogn, to use these insane little plastic tubes to hold together, and in quarter, the two halves of a DRIVE axle, for heaven’s sake! Whoever thought it’d be OK to take a drive axle and cut it in half like that anyway?
I jam a piece of brass tubing over that bushing on each side on the main gear after slathering the whole works inside and out with J-B Weld. By the time I’m done, that geared axle set is the STRONGEST part of the loco. Oh, and while I’m at it, I’ve corrected the too small check gauge on these beasts as well…
It’s just amazing to me the Aristo releases them into the market with these obvious and quite serious flaws.
But then, it has to be said that these fixes DO result in a very fine piece of machinery, especially if it has the non-sintered wheelsets. I can count on these beasts to hold up very well at shows where I happily let kids operate 'em all day long… I don’t bother with the smoke and sound effects, and the models are adequately detailed for my use. To me, solid reliability is the most important aspect.
High detailed realism is OK - great -for contests and photography and museums, but nowadays it’s far down my own personal list.
