Hello everyone,
What a nice little community I've stumbled into, I'm hoping you'll might be able to help me.
I've got the itch to repair and refurbish my old Tomy Trains (Red No.12, Green No.78 and Blue intercity 125).
Reading over the more common issues and fixes I've come to the realization that my gears are really beyond repair, to many cracks, the timing is off up and down the gearbox, its not really a gearbox anymore more of a click&snap box. I'm opposed to using donner units as it kills one train for another.
Does anyone have a convenience list of the full gear set in these old units?
The Pins, rods and springs are in good shape, so they can remain, its really the gearing. unless the timing issues are also releated to housing wear. The plastic on metal pin mounts grinding and wobbling, (how tight should the pins rest in their recesses?
Thanking you for any help you can provide.
