So this has been documented over here

http://lumberjocks.com/topics/62621

but the executive summary is that the Grizzly G1023 I took
delivery on in May turned out to have no set screws in the
motor shaft keyway. This had to have been a factory
mistake as I can’t believe there’s any way you get all
four locking set screws to back out in under two hours
of total run time on weekends in some guy’s garage.

The original “hey what’s happening here?” video I posted

http://youtu.be/h2YOOANCkKY

And here’s an image of the key causing the obstruction
once I was able to determine what the problem was and
had the table top off.

The key slides back and forth in the slot quite easily with
just two fingers pushing and pulling.

Two people have suggested that the key and/or pulley
or motor shaft might be damaged. One suggested that I
demand a new pulley from Grizzly. I am now concerned
about any long term damage that this may have caused
but do not have enough experience to evaluate this
myself.

Any advice on what I should do? What should I look
for? How should the key fit? How much slop is too much?
Should the key slide easily, or should it be press fit?

Thanks all in advance.

You said the saw has been run for minimal time. I’d say there’s no damage to the saw, though I have seen the sheaves/pulleys get “wallowed” out with extended run time. I’d also guess there’s no damage to the key, though I haven’t seen too many that slid in and out with finger pressure. With the key in place, if you can’t detect any wobble in the sheave I’d replace the set screws, give it a test run, and call it a day.

Checking belt alignment and set screw tightness should have been part of setting up the machine before first use. Go ahead and replace the set screws with self locking ones.

Papadan, this was my first large cabinet saw purchase. I took
about a week to assemble it, taking my time, taking no short cuts
and following the instructions in the manual to the letter.

There was nothing in the manual about checking set screw tightness.
In fact, it’s impossible to get to these screws without taking the
table off, which I doubt too many people do straight off the pallet.

Now I know, and if I ever purchase another I’ll check,
but I can hardly be faulted for what was a manufacturer’s
mistake.

The key can have almost no clearance to a few thousandths clearance. if there is some clearance and no rust the key will slide in and out. If the edges of the key look banged up, there may be some damage to the shaft or pulley. You can get set screws with a locking patch or use a light duty thread locker, one that is not permanent.

Are there marks from screws on the key from the factory install?

If the pulley is busted, replace it. Measure the motor for round out. Install the pulley, measure the pulley for round out. If your happy with what you see, call it a day. I’m sure Grizzly will stand behind their product, but figure out if the motor is running true before bothering them. Also, try running it without the pulley installed to see if it rumbles at all.

That key doesn’t look to be the right size. There should not be any gap showing between the motor shaft and pulley. Is that a crack I see at the bottom of the picture?

How does one measure for round out?

Ron, that’s not a crack, just the way the settled. Are you referring to
the gap between the top edge of the key and bottom of the dado in
the pulley?

The set screws arrived from Grizzly this evening.

So here’s the motor running with the set screws installed.

Perhaps one has wondered what this looks like without the
table and dust shroud installed. I had a sudden urge to run my
fingers along the top of the arbor pulley, but resisted.

I want to applaud you for getting down there and applying your own fix, with grizzly. You could have called grizzly and b itched and moaned until they sent a service tech to you. It seems alot of people on this site want a Ferrari when they order a ford.

Doing this yourself is a lesson learned in life long table saw maintenence and prevention.

Glad to have you on the site and for your through documentation of the problem.

was there a difference betwen the new set screws and the old ones? it is possible the hole for the set screw was not threaded all the way through? I would take the pulley off and make sure that they were. otherwise the setscrew will bottom in the thread and feel tight but not be tight on the Key.

I am glad that you solved your problem. You went above and beyond to get it fixed.

However, even if I ordered a Ford, I would expect all of the bolts and nuts to be in place. Yes, Grizzly is a lower cost option and a pretty good one. Yes, the fit and finish may not be as good as other more expensive ones.

BUT….there is no excuse on earth for not having the set screws in place. I would not have moaned and groaned at Grizzly but would clearly let them know that I was not happy and they should do more than just send me the set screws. There is a certain minimum requirement for equipment and not having the set screws in place just does not make it.

Thank you Red and Paul for your kind words.

I would rate Grizzly’s customer service on this a C+.

When I first called them I had a video uploaded to
YouTube that I expected to be able to walk through
with the tech on the phone. The tech said he
could not access online videos. So I attempted
to explain the problem verbally and that was a complete
and utter failure. Start, stop, back up, correct his
interpretation, reexplain. Just useless. So he said
I would have to email the video file. No urls. The
file itself. And said I could expect a response in
24 to 48 hours.

Well google won’t take files over 25MB and the video
was 41MB, so I went ahead and emailed the url to
the YouTube video.

The second tech, who contacted me the next day
was much more knowledgeable. They did in fact have
access to YouTube and he suggested the set screws
on the pulley may be loose. Note he was still wrong,
but he was close enough to point me in the right
direction and allow me to find the key.

But this is where they really pissed me off. When I
wrote back with video and photographic evidence that
the set screws were missing, and I believe they had
never been installed, the response from the Grizzly tech was
quote, “I cannot speculate as to if they were ever
installed or not.”

Really? Before that I was just annoyed. After that
I was pissed. They have to know that there’s an
vanishingly small chance that those screws backed out
on their own and yet they are going to be all legal
on me? What, did I remove them myself because I
just enjoy hassles? I just found that very, very insulting.

The proper answer would have been, “We are so sorry
that our factory forgot to install the set screws, we will
take steps at our factory to ensure that this never happens
to another customer, and to show our good faith we are
overnighting you the screws. They should be there before
10am tomorrow.”

Instead I got “Eh, we won’t admit that we screwed up,
but we’ll send you a set of screws. They should ship in
3 to 5 business days”. Which means they’ll ship in 5 and I’ll
get them 4 days after that.

The spectacular above and beyond customer service
would have added, “Oh and we know you have to
take the table off to fix this, and we know you ordered
a superbar dial gauge with the saw, so we are going to
send you a master plate to make it easy for you to get
that top back to dead on alignment.”

One of the reasons I chose this saw was because of Grizzly’s
vaunted customer service. In this case, while I have the
screws, I still have a table that I have to get back to dead
on alignment, and I’ve lost about 10 days of use, and Grizzly
really did just the bare minimum they were required to by the
warranty they offer.

So yeah, C+ on customer service. They get the plus, because
after I bitched about their shipping they agreed to send them
by second day UPS.

No one will ever admit guilt and that was what you were asking. I think you got what you asked for at no cost. I am not asking you to change their rating but I find that if I get all huffy with the tech I usually get less.

The other day I was talking about round out. Either attach a dial indicator or anything else you can check relative position to. Make sure the pulley doesn’t wobble up or down, side-to-side any more than you find acceptible. If you find an issue then that would be something to bother Grizzly about. Tighten those set screws down well, they have the tendency to back out.
