Boy your spot on ! Just going thru a DW708 and DW718 I thought Dewalt loctited the bearing in place. I ended up breaking the outer race so I could get to the inner race. Man it's one stubborn..... I'm going to cut the inner race off. Can't heat it and can't get puller on it. I didn't know the fan was part of the armature I thought it might be so I left it alone. I used to work in a motor rewind shop so it's straight forward but geeezzzz it aint easy. Thanks for your videos they help !
I would not advise putting the armature in the vice like that. pressure on the fins and windings is not good, damage some of the windings and you'll almost certainly require the armature to need rebalancing. these are super high speed motors, the slightest vibration means more bearing replacement more often. Also make sure you use high speed bearings. Most places have to order them in, they are 5 times more expensive than the standard cheap ones but last a very long time. Do it once do it well
Great informative video! thanks for publishing it on you tube! Could I ask you how would i tear down my Rigid 12 inch miter saw so I can get to the bearing by the blade.? Thanks, I greatly appreciate your assistance. Flywelder 3-3-2011
What symptoms suggest a failed bearing? My 12" dewalt feels/sounds like the rotation is being slightly restricted. This occurred after cutting Hardie board for a few days. Is this the bearing? Brushes? Thanx
Eyal Volki The removal of the belt pulley is pretty straight forward. Remove he retaining bolt or nut. The pulley and shaft are keyed to insure a snug fit and sometimes the manufacturer will use loctite on the shaft to help hold the pulley in place.

I buy a facom bearing puller RE: U.306-180, can i used it to extract some induction motor bearing?
@therockkkkher In this case, the bearing itself was the part that had failed and needed to be replaced.

Just removed front bearings on my two saws the 708 and 718 man it was like pulling teeth !
why not showing how to remove the belt pulley?
