Not universally true Bob, not even close. Many of the MTH dummies do not have gears. Some just have the gears on the actual axles, but not the intermediate gears or the drive gear that engages the motor worm. I just stuck another set in the box from a repair, no gears in sight in the dummy trucks.The dummy trucks are the same as the powered trucks. They even have gears on the axles. Easy to convert a powered unit to a dummy. Just remove the motors, pickups and electronics. I've done it.
Yes. The motor is assembled to the motor mount. That assembly is connected (through the frame) to the truck. To make a powered unit into a dummy, you first remove the motor/motor mount assembly from the truck, then remove the motor from the motor mount and then finally reconnect the motor mount (through the frame) to the truck.On MTH can you remove the motor and still have the truck attached?
