Replacing the motor in a Dapol 14xxx engine

[Jaycee068]

I have a 14xxx with a dead motor/jammed drive chain. Does anyone know how to remove the motor from the chassis? I've got the bodywork off.

Ta.

Before dismantling further is there still a circuit from wheels one side to wheels the other side ? A meter on ohms is the ideal test method, but a 9V battery, some wire and a 12V light bulb to create a simple test circuit will do. (Or if a DCC decoder is installed, try a reset and readdress on programme track.)

Thanks for the prompt reply. I've had the chassis on the track and tested with a multimeter. I get 12v across the motor terminals with the power dialled right up so I think there's definitely power coming through the pickups. No life from the motor though. I'll check the ohms and see if there's anything going thro the motor itself.

Afraid I can't help, in fact I had to google Dapol N gauge 14xx, didn't realise they did one and wanted to be sure this wasn't a missposted query for the "built by everyone but Bachmann", 00 scale one.

Rotate the motor by hand whilst checking for continuity, some motors are series wound and will either indicate continuity or not, others are parallel and you can measure the resistance/check continuity through each pole.

OK, so no reading across the motor terminals when tested for resistance. Looks like I've got a dead motor.
