Dewalt table saw 744 type 1 problem

[Elche]

My 4 year old table saw wich I use often the motor started to make like a squealing noise at start-up for awhile and all of a sudden yesterday it starts up but with very little power I can't even cut anything and it smells like something is burning so I thought the brushes are gone but after I checked them they look fine with not so much wear what do you guys think it is bad motor?
Thanks in advance for your help.

Hey elche,
chances are the rear or commutator end bearing has seized causing the initial noise..the burning may be the hsg starting to melt around the bearing..ugh..You will need to address this as soon as possible..remove the rear motor hsg and inspect..if not too much damage you may be able to just replace the bearing and rubber boot or sleeve..worst case is replacement of the housing and a shorted or damaged armature..
you may also want to replace the front bearing..this may also be for the service center to perform..hope this is helpful..

Thanks Craig, it is the bearing at the back of the motor don't see any signs of anything melted so I will replace both bearings don't want to take any chances on the other one going bad just another dumb question, how do I remove the bearings?
Thanks again.

Hey,
The best way is to pull the bearings is with a OTC #1020 puller [brand]..you may be able to find one or something compatible at your friendly auto store..last resort is stopping into a local repair shop and having them pull it for you..no matter what you do be careful not to damage the armature or fan...[ there are other clever ways to remove but you real;ly have to be careful..]
take care..!

nope,
just do a google search for a otc puller and you should have a few links come up..they range from about $28.00 to $48.00..but just check out what it looks like and you can probably get something close at an auto or hardware store..[hopefully around half the cost!]..
if you do have a local repair shop nearby it might be best just to have them pull them off..heck.. they might not even charge you..! hee..hee
