Bad motor, I think?

[ecg123]

Was running my big rock a couple of weeks ago and started running real slow and I heard a whining noise coming from it. Today I pulled the motor out and pinion and spur gears looked fine. I hooked the motor back up to the truck. And that was where the sound was coming from. I heard the bearings go bad in the motor regularly. Just want to make sure before I buy a new motor. Thanks

Take the motor cap off and have look if the front or rear motor bearing are still OK or not. If so and the rest of the motor is still good all you need is replace the bearing(s).

You can also get a very good aftermarket brushless motor for a pretty good price. Stock motor is a 3660 motor and 3200kv.

Here is a good match:

Bearings are shot. Will order some new bearings later. I found a new motor on Jenny’s for 36 dollars. I am going to repair the old motor for an extra. Thanks for all the help guys!!!

The motor I posted is only $5 more and is a much better motor than the stock Spektrum motor that you will get from JennysRC.
