TKO Ceramic 12x21x5mm Rear Engine Bearing (TRX 3.3) (1)
excellent bearing for the older novarossi .12 engines with the 12mm crank, 2 gallons in my nova/top.12 and bearing is still smooth and slick. also when installing make sure the balls are facing outward towards backplate.

This bearing is very very poor I killed two motors with this bearing first was a os 18tm the balls well out the race and wipe out the piston and sleeve. That wasnt enough for me so I gave TKO another try. This time the victim was eb mod os18tz race failed again balls and metal shreds destroyed the motor. Only ran 4 tanks with this motor after break in, This motor was still new. Learn from me save yourself some money and some tears dont F N buy this [email protected]
