Dear Ventana, On quick

Dear Ventana,

On quick glance, and with no other info to go on, it _looks_ like the motor and PCB from a Athearn (Current/Horizon-era) SW1500 or similar. If it is as suspected, then yes, it should run fine on a analog layout.

Note the little circuit board plugged into the rainbow-colored loom or wires (9-pin JST socket). Again, if this is what I _think_ it is, it's a "dummy jumper" to allow running on analog.

To convert to DCC:

- remove that "dummy jumper"

then either
- plug a NMRA 8-pin decoder into the 8-pin socket on the main PCB

OR

- plug a 9-pin decoder into the 9-pin JST loom where the dummy jumper was plugged in

Hope this helps,

Yes, sorry, i meant to include that it is off a Athearn SD70ACE.  thanks for the link.

I need to replace the dogbones to make this work in a Athearn GP40 bluebox.  I found these http://www.athearn.com/Products/Default.aspx?ProdID=ATH90114which are close to my rough measurement of 1".  Does anyone have an idea if I am on the right track?

I'd be getting out the micrometer and make sure of the required measurement.

I see they have a set that measures 1.055". It may be easier to shave .055" off those than try to stretch the ones you linked to.

Close only counts in horseshoes.

lol, thanks, Alex.  I

lol, thanks, Alex.  I re-measured and it's 3/4" from the worm gear to the flywheel and about another 1/4"  into the flywheel.  I'll order them, I think it will work.

thanks for the help.
