I got a really good deal (FREE) on a Mattel ride on Caterpillar dump
truck for my son at a garage sale. It had no markings or battery, so I
popped in a 12V motorcycle battery. When I switched it on, I heard two
pops from the back of the vehicle. I think that I burned out both
motors. So now I'm looking for replacements.

Since my quest began, I've learned that this toy takes a 6V battery to
drive both motors. I guess this explains the "pop" sound and confirms
my theory of the motors being blown.

The local repair shop wants $20 each and $100 to install them, which
is way more than the toy is worth--new. Does anyone know how I can buy
these myself? The shop wouldn't tell me anything.

Thanks for all the help.

Usually a DC motor will run just fine on 2X the rated voltage for at least a
while, are there any fuses? I suggest checking for voltage at the motors and
working backwards. If they are in fact bad, remove one and look at the size,
you should be able to find a surplus motor that can be made to fit. Electric
motors from micro miniature to massive multi-hundred horsepower industrial
motors tend to come in standard frame sizes and mounting configurations so
it's usually not too hard to sub one.
