    Default TP4050 V1 motor bearing size

    Anyone know the size bearings used in the TP Power 4050 V1 (gold end bell) motor? The OSE store lists sizes for the older V2 and I'm not sure if they've changed.

    I haven't had the time to pull the motor and pop the bearings to measure myself. I'll get around to it eventually and will post the measurements here.

    8 x16 x5. All the 5mm output shaft are machined down from 8mm on the ones I have. I just replaced a set in one motor last week.

    Thank you. And just to confirm, this was a 3 piece design, with gold end caps?

    Turns out my bearings weren't bad. First run after the Boca swap, still had the squeal. It was caused by a cooling hose stuffing tub seal that was a bit too tight. Oh well, spare bearings are never a bad thing.
