My ShopBot was 10 years old when I bought it 5.5 years ago. I don't know if the router motor (3.25 hp Porter Cable 75128) was 10 years old or not, but I've used it regularly for the last 5.5 years. This week it was noticeably louder and I could see blue sparks through the vent holes in the housing. I swapped it out with a spare from my conventional router table and it's obviously smoother and quieter.
My question: Is it worth trying to rebuild the old motor or just scrap it? I assume it needs new brushes, but is there more to it than that? Even rebuilt, will it be worth using or is it likely worn to the point that it has excessive run out?
If anyone has had one professionally rebuilt I'd appreciate contact information and an approximate cost.
I've ordered a replacement already and if anyone's interested I got it for $285.99 delivered from "Factory Authorized Outlet". There's a $20.00 discount until the end of the year and free shipping. They didn't collect tax for me, but YMMV on that. I bought the one I just put in the ShopBot for $255 or so back in 2011. I guess $30 isn't too bad over 4 years.
Thanks.
