Grizzly G1023SLX - Lost Arbor Nut?

[DanKellen]

Greetings NC Woodworkers, I’m a new member and was wondering if any of you might know where I might find a replacement for my lost arbor nut? I have an old Grizzly G1023 SLX table saw. The arbor nut is lost, and Grizzly tells me that the nut is out of production, and the replacement part will not be available until September. That’s a long time to be out of business! Any ideas or leads would be greatly appreciated!!!

Welome Dan, good place to be -To your issue - Common nut, easy to rebuy find the thread and diameter (I believe it is a 5/8 x 12 tpi Right hand) some models are left hand. Either way, this is a nut that can be purchased. The one thing it does require is that the face is milled flat to properly retain the bladed from shimming (wobbling). If it is a left handed you can buy a unisaw arbor nut they are 5/8 12tpi left handed and is the same spec as the Grizzly.

Where are you located and is your saw right tilt or left tilt? I may have a spare for a right tilt unisaw. I believe they are the same nut.

If this helps:

From Grizz's website:

Appears to be a left-tilt

Thank you very much for the response Casey! I agree with the size, tpi count, and right hand threading - exactly what I discovered as well. Unfortunately I didn’t find that combination to be as common as I had hoped. I spent most of a couple hours online trying to find a fastener/hardware store that would have that specific nut. The most common thread count seems to be 11 tpi for a 5/8” nut. I am hoping someone has found a “honey hole” where they were able to find the elusive “12 tpi” 5/8” nut! Thank you for your time and expertise, and confirming I’m on the right track!

From what I can find, that is a 5/8-12 RH nut. A quick google search lead to this link:

Thank you Fred. I’m in the Charlotte, NC, area, and my saw is left tilt. The threads on my arbor are right handed. I that’s the case with your nut I’d be interested in chatting with you!

Thanks Rick! I found this nut and bought it (for the PowerMatic arbor) and for some reason it’s not threading on my saw. I’m reluctant to force it on - don’t want to bugger up my arbor. I was thinking maybe the machining between the brands is just different enough to not allow them to be used interchangeably? Not sure - was really hopeful when I bought this one.

Well, how about this one:

ARBOR NUT 5/8-12 RH at Grizzly.com

www.grizzly.com

for the current 1023 saws. I'm now curious as to whether your arbor is different from the current production saws.

The PowerMatic nut is an Acme thread ... thought pretty much all of the arbor nuts were ... but if not, that may be why it doesn't fit

Good luck!

Regards,
Rick

I don't think it will work. Opposite threads.

I bet it is the same nut used by Harvey. They might have built your saw in the first place.

 

[Woodman2k]

Grizzly builds there tools in several Taiwanese factories and Harvey only showed up in 1985 so the 1023 was already in production.

Yes, but production of tools tends to migrate year to year. A few still in Taiwan, but I think the big four are all mainland.

The thread size will likely be a square thread rather than an acme if it follows the Delta USA-made Unisaw pattern used for years. The flat top of the threads will lead the inexperienced to conclude it is an acme thread. That was not the case with Delta saws and many other Delta clones. The Powermatic saws do indeed use an acme thread as do many others. A standard V-thread will not work under any circumstances.

See if you can borrow a Unisaw nut from someone to test on your saw. The Marathon-made Delta 7" grinders used a Unisaw nut on their LH shaft and Had an opposite hand threaded nut on the RH side.
