Help!
HET Motor Bearing Dimensions

I have a 700-60-1485 with a sloppy front bearing.
I need to know the OD and thickness, I know the ID is 5mm
Thanks,
Bob

I usually take the bearing out and measure it. I have gotten away with just using a metric ruler on some of my nitro engines.

I tried to remove the front and read plate on a 700 series motor and had to make a special puller to remove the from plate on the motor.

I had to use alot of heat in the plate since it epoxied on.

I did not even try to remove the rear plate, since there was no place to pull from.

Hope this helps.

Here's an update the bearing is 13 x 5 x 4.
But how do we get the bearing out???
Well Stu came to the rescue and told me how.

First take two 3mm x 5mm cap hols bolts and thread them into two opposing holes on the front bearing plate. The Cap head bolts will keep the bearing plate from spinning.

Place a metal hose clamp at the back of the motor around the rear bearing plate don't over tighten it.
Take a torch and heat up the front bearing plate area around the circumference of the motor to soften the thread locking compound that the factory uses.

Once hot place the motor front down into your bench vise and turn the motor to the right as it is a left hand thread. The Cap head bolts will keep the bearing plate from spinning.

Be aware that there is a brass spacer washer on the back end of the shaft so don't loose this when you pull the stator out.

I am guessing that "to the right" means clockwise if it is a left hand thread??? And for a rhetorical question..... why would they make it a left hand thread?

So the motor torque tightens rather than loosens the front plate when running.

I agree, the motor can run in either direction.
