I suspect that the brushes you got are fine.

Made a stop at a tool guy's shop. Known him for almost 30 years now. He glanced at my schematic, said the bearing part numbers meant nothing, said "we have bearings", bring them in. If I bring him in the whole motor, for $100 or a little more, he'll open it up, presumably replace all four bearings, the brushes, and it will be done. Me, I do not know what I am looking at if there is a problem.

 

So I'm into this saw $50 cash, $60 gas and tolls, $120 motor rebuild, time, wear and tear on both me and the truck . . .  I'm talking myself into thinking it will be a decent deal when all is done. And I can get my money back if need be.

 

The West Philly curb pile is GONE (sob!).  I snoozed, I loozed.

 

The new Delta (SN K8838 = August 1988 ???) weighs a whole bunch but I got it into 3-4 pieces. Got the motor out very easily. The motor guy seemed confident he has the bearings. Took him the motor along with two boxes of Speer Gold Dot 9mm I've had for 15 years. An advance gratuity works wonders.

The Delta part numbers are just that, Delta part numbers. 

The motor guy will replace them using the numbers off of the bearings.

If the bearings have no numbers, he'll go by the bearing dimensions.

That right there Jim...

While you have it apart you might go ahead and replace the belt also.  Likely it still has the original and it's pretty "not so pliable"

DING DING DING ! - The motor was completely disassembled. All 4 bearings fine. Brushes fine. It was the belt. Plus loads of white wispy plastic inside the motor. The seller may have been cutting  HDPE cutting boards or the like.

 

Glad I took it to a pro because I know nothing about electric motors. Reassembly Thursday maybe. Gonna rip a whole lotta wood.

Cool!

To a point.  Wow, is this loud!  The tool repair guy had nothing but trash to say about this motor but hey, it should rip heartpine to its full capacity.  The saw, cast iron top, all metal, it's entry into the club.  A jointer is still on my horizon but a quiet 8" saw with excellent dust collection is on my ticket. 

 

Motor with no blade attached: if you are gonna play this video,

Aaah, that's the sound of more power.

I agree with Dave sounds powerful

It was not bad. Full height through heartpine was a slow push. Before buying I was able to push the saw hard enough to trip the relay thing. But no issues once rebuilt. Granted, I did not try to speed up cutting.

 

That motor is dedicated 120V. Does a 220V motor run more quietly? Power dynamics are better?

 

I did not do the "feel" test on my extension cord. Next time I'll feel it for heat. I "think" that GFI is 12' from the box, run with 14g.

 Sounds OK to me, but SWMBO says I'm DEAF in one ear and can't hear out of the other. 

Full height through a timber of well seasoned heart pine, that wouldn't be a quick push through my saw - even with a new blade.  I'd say you have it running pretty good.  I would visit Harbor Freight for a 12 ga. extension cord, and not plug into a GFI if I didn't have to.  Those last two are just me, no real reasons that I know of...

 Found two yesterday. 

Now have more than enough to reach everywhere in the "Two Weeks From Anywhere" yard.

 I doubt I'll be thinking that if/when I ever have to wind up 500' of it.

 

Probably not as heavy as that 100' 10 ga. cord though. 

I was gifted a 100' reel of 16 gauge with a 15 Amp breaker built in. Stretched to 100', a Skill 77 trips that breaker every time. Kinda worthless in my shop. It'll run a jig saw and a sawsall. That's  about it. I suppose it would power the routers but, there's another circuit fir them.

Your saw is considered to have a direct drive motor.  Here is a comparison.

Not a expert so I searched and found this to give you some ideas. One problem tho and maybe resident electrician @Artie will chime in . Some motors cannot be converted. I do also think 240v runs cooler.

 

 

And here is another result

https://www.woodtalkonline.com/topic/1780-convert-to-220v/

Kinda difficult to say, so many factors. If they were to be used in your own shop, and 220 is available, that’s how I would go. Same, maybe a wee bit more horsepower with the 220v, but 1/2 the amps. Smaller gauge wires=cheaper to wire, breaker difference is marginal. If you were to be using the tools at multiple locations, 120v is most common, and pretty much all 120 cords plug into the standard receptacle. I know my Shopsmith advertises an extra 1/4 HP at 220v. 

Long day yesterday. Started out in first van lost brakes, went out in second.

Got back around 11:00 PM.

 

Somewhere in there is a 1940's-50's Dunlap Bench Grinder that doesn't look like it was used much at all along with a few other goodies. Photos when we get unloaded. Have to have breakfast first though.
