I have an HO scale Bachmann B23-7 that I want to convert to DCC.  How do I remove the motor brackets so I can separate and isolate the motor from the chassis?  Thanks much for any help.

Look at the exploded diagram: http://www.bachmanntrains.com/home-usa/dwg/dwgs/HO_B23-7_DIESEL.pdf

You should be able to disengage the motor bracket 'hooks' from the bottom of the loco, then lift the bracket up and out.

If at first you don't succeed, throw it in the spare parts box.

Hi Len:

Thanks much -- unhooking the latch from the chassis seems to be my problem -- one bracket is no problem but the one on the other side just does not seem to budge.  I'll keep working at it -- hopefully not until it breaks because there are no replacement parts.

I usually slide a tooth pick in to keep the first side from reengaging while I work on the second side.

Hi Len:

Thanks;  I couldn't get the toothpicks to work and manged to break one of the brackets - I don't think Bachmann has replacements for sale -- here comes the jury-rig or a lot of parts for the parts box .

Will this work? Similar ones for the F7A/B, GE 70 Tonner.   Joe

Hi Joe:

Thanks;  one of those cradles just might work -- very interesting, if they fit the chassis screw holders holes, they would also solve the problem of insulating the motor from the chassis -- I was going to use electrical tape.  I guess I'll be calling the parts dept. on Monday.

Thanks again.

RTV rubber makes a great motor mount,just keep it out of the motor and brush holders. It has slow cure time so everthing can be adjusted and set,and is semi permanent meaning the motor can come out without much trouble. Also dampens the motor sound and vibration to no noise.
