Does anyone have repair experience with the Delta "direct drive" (actually
gear drive) table saw motor units ? Mine has been acting funny , has almost
a "howling" sound under load , and today the blade stalled in a cut . Motor
still at full RPM , blade dead stoppped and that noise coming from the motor
unit . I know there is slippage in there , need to know if this is a major
repair or just an overload device that I've , well , overloaded .
If this turns out to be a big deal I'll just move the fence over to the
"new" belt drive unit I got at a yard sale (25 bucks) . I did nurse it
through cutting all the OSB pieces for the trusses I'm working on , so it's
not time-critical for now . I'm suspecting the driven gear on the arbor
shaft is pressed on and is slipping ...

First reaction would be to check to see if any of the shafts are keyed, if so, check and make sure none of the
keys are sheared.

My first reaction would be to check to see if the blade is tight. I had
a circular saw that did not seem to hold a blade tight, no matter how
tight I made it. It was a cheap saw that appeared to be needing brushes
anyhow because of the sparks that came out of the holes by the motor. I
just bought another saw rather than screw with it.

If it's not a loose blade, or a sheared key, you probably have a
stripped gear, or a bad bearing which is allowing the gears to slip. If
that's the case, you might have a costly repair, if you can even get
parts for it. Delta is a good brand name though!

That would involve disassembly and there's no time for that right now . I
gotta get this roof on as soon as I can . Also , if it were a sheared key it
would most likely not drive at all and/or make a different sound . Depending
on what I find when I have time to dig into it there may be a key installed
(I love having a machine shop) but more likely is that I'll start using the
other saw I just bought .

A stripped gear wouldn't drive at all . Anything short of a stripped
helical gear I can probably fix in the shop . Just gotta figure out the
time/cost/benefit to see if it's worth my time . Thus the question about
direct experience with these motor units . Blade is tight BTW .

It could easily drive with a sheared key 1f the set screws were still in place. It would drive but slip as
you have described. Regardless, I would stop using it or fix it before you completely destroy a shaft.

I'm done with it for now - and if I trash a shaft I can just make a new
one on my lathe or repair the old one ... the only thing I can't do is
helical gears . But why , when I have another saw that just needs a fence ?

You need to go to "Bargain City".

Just go to the nearest big city ghetto and look for a guy standing on a
street corner wearing a long trenchcoat. Years ago, those guys just sold
stolen watches, but since watches are not used much anymore, because of
cellphones, those guys now have stolen powertools, phones, computers, tv
sets, and even table saws under those coats. Buy em CHEAP!!!
And if you give the guy a tip, he might even give you a "discount
coupon" for low cost prostitute service. (Her job is to teach you how to
use that saw).... Plug in the saw..... Now pull out your dick!!!
