Picco motors use 7x19x6 front and 14x25.4x6 rear. I just put the block with bearings in the oven at 400 degrees and get the motor over 350 and the rear bearing should just fall out with a little tap and I use my tire wrench to tap out the front. I put the new bearings in the freezer and put them in cold with the block still hot. PS wear gloves. www.tkocompetitiondev.com click on rc specialties then click on ceramic bearings then 14.25.4x6 and you will have your bearing
