Porter Cable 75182 repair, or just trash it?
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.
FWIW: collet runout solution for these motors
Recently bought one of these motors with an Excalibur router table, and found excessive run out- as in you could see the wobble as it idled down. Researched on line and found this is normal- mine measured .004" and there are examples showing that up to .006" run out is common.
I followed advice posted by precise bits .com, picked up their ER style nut and collet set for the Porter Cable, and things are much smoother now. Not a cheap kit, but incessantly pounding your bits, workpiece and the motor itself is senseless.
Kit included ER-style nut and matching wrench, 1/4 and 1/2" collets plus some cotton applicators and collet care sauce. A thorough dissertation on collet care and use is included, so I'll be more attentive to the spindle on the shop bot as well. Not bad for under $100.
So- while tending to these motors, I'd recommend you take a look at their offerings.
