Title: New gears Railtruck On30 bad result.
Post by: Hobojohn on January 25, 2017, 05:38:16 PM
Got a whole new set of gears for the Bachmann On30 truck. Assembled them, the result was very disappointing for me.
Instead of a smooth running truck, which I expected, I got a noisy, shaking, wobbling result with a slow and heavy running truck.
Assembled, dissassembled,  cleaned about three time, every time it got worse, The led wires broke and in the end I got a short circuit somewhere in such a way that the motor does not want to run anymore.

Yes I know what I was doing..

Wished I had not taken the truck apart and only replaced the rear axle where the crack was and not the whole drive train.
It seems to me that the white gears are slightly larger than the black crackling ones.
What caused in my case a slow and heavy wobbling drive of the truck
It was a nice rebuild truck with a Backwoods Miniatures cab on it and a Boulder Valley Box.
Even with sound.
The gears cracked while the truck was only laying in its box....

It is dead now............ :'(

Sorry Bachmann

A small history about one of my two rail trucks.
10 years ago i bought the #1.
It ran awful and i mailed Mr.B telling them so.
I didn't know about the splitgear syndrome then.
They sent me a complete unpainted new one for parts so i could repair the #1.
It ran like clockwork and i put it away on the shelf.
Then the splitgear issue erupted on the net and i ordered two repair kits just in case.
A month ago i decided to run #1 again, no joy , splitgear.
just by standing around.
I tried to fix the gears and demolished one set.
I took the second set and it moved with a lot of gear grinding from the diff.
It is sitting on it's shelf again as a static model :(

I've long heard about the gearing problem on the rail buses and rail trucks (and seen first hand on another guy's layout the way Bachmann On30 shays come apart over time), and it's sad to see.
Bachmann stuff, in many cases, is 'bullet proof' in it's design and function.
But a few of their designs seriously fell through the cracks.
I'm just glad my beloved On30 ten-wheelers didn't have this issue generally like the others have...
