Just to update this thread, I replaced the bearings in my 21-5 yesterday using an OFNA bearing puller and an oven preheated to 350 degrees. The front bearing came right out using the bearing puller while the rear fell out after being in the oven for 20 minutes. The new bearings when in without incident. So for those of you running plus size bearings the TKO are a great upgrade for your mill.

Thanks to everyone who chimed in on this point. Thanks to Peter Martin from TKO for his input.

im replacing the rear bearing in my v spec with a tko ceramic that i ordered yesterday. I heated the oven to 450, let the motor stand for about 7-10 minutes and then took the case out with a glove, lightly tapped the case against the table untill the rear bearing fell out.

I do have a question though, since the front bearing is like new i decided not to replace it, is it safe to re-use a bearing after the block has been heated with the bearing in the oven in order to remove the other? or does the oil from the fuel re-lube the bearing once ran again and all should be good?
