New replacement motors?

[suprb6970]

I have been searching for new replacement motors. I have found none.
Here is what I have learned by searching.
Tyco US1 used a box style box of course, but not all box style motors are same from this era.
US1 used a Barrel Brush Mabuchi or Johnson Motor. Tyco did use this motor in other slot cars. but none of them are the same as US1.
They used this motor in later HP2 curve hugger and early Command Control cars also early Jam car vans. The later Jam Car chassis (TCR) used a Mabuchi motor NOT Johnson no barrels. You can tell the difference in the chassis. The newer chassis has a large hole in the center the chassis, the older does not.
The differences are significant. The HP2 motor the output shaft is too short for US1.
The Command Control motor is also too short. The Jam Car motor is close but also too short. Command Control armature windings are different also Command Control (TCR) used a VAC output power supply and not VDC. Ideal TCR chassis also use Johnson Motors but are once again too short.
Other Tyco products use box style motors to but they are Mabuchi Motors, such as HP7 chassis.
These other Johnson Motors can be useful. You could use the parts to rebuild your old motor if your armature is still good.
