Topic tags/keywords: grizzly motor question tablesaw

Hello, New member here although I had a membership a few years ago but I’m not much of a poster, and I do check in regularly without logging in. Thanks for all the help this forum has given me. I now have a specific issue:

I have a GO715P tablesaw. Bought it lightly used. It was manufactured in 2016 so just 4 years total of light use.
The motor refused to start. Tried to spin by hand ….no luck, completely locked up.

So I thought I would check the bearings since I can do that… bearings are fine. Capacitors seem fine (no swelling/leaking) BUT: The windings had somehow melted/fused themselves to the armature. (forgive if my terminology is off).

OK, Called grizzly. Thought I would order a new motor. NO LUCK> This model discontinued and Grizzly has no motor or even any suggestions. (kinda disappointed that this new of a saw has no major parts available)

Called a local motor shop and they though it would START at $600 to re wind the motor plus any other stuff it needed.

NOPE! the saw is not worth that (to me)

This motor has the support bracket integral to the motor as well as an adjustment bracket welded to the side so a of-the-shelf motor wont work.

While I hope no one here has had this problem, I hope someone may have a solution?
Otherwise, I will have to scrap a 4 year old saw… And to be sure, the new one will not be a Grizzly. I know they make good stuff, but I personally wont go there again unless somehow this can be fixed at a reasonable price.

Thanks
Gary

Wow. Just looked at parts list:

That motor uses a very unusual motor mount.

It only uses one welded tab (unlike Unisaw motor which uses 2), and it has a custom front plate and front bearing mount:
https://www.grizzly.com/parts/grizzly-discd-motor-end-plate/p0715p106-7

2 Recommendations beyond rewind:

1) Create your own Frankenstein motor:
If you can find a 2HP motor with same frame size, and bearings are same (likely); then you can swap the front plate from bad motor to new one. The carefully grind the welds holding the tab to motor case, and weld the tab to new motor in exact same place.
Folks have replaced Unisaw motors by swapping the welded tabs for many decades. Any competent welder (even marginal welder like me), can weld the tabs on new motor frame without damaging the new motor. The key is limiting the current/voltage to avoid burn through.

2) Call Harvey Machinery:
Harvey uses the exact same fence clamping mechanism on their new saws as Grizzly G0715. The G0715 was discontinued about same time Harvey starting selling saws direct in US. If they made the saw for Grizzly, they should also know the motor OEM and be able to order a replacement P0715P106 PN. Expect the process to take 4-6 months if they have ship part from China. Who knows, they might be using that same motor in current model and have spares in California.

FWIW – There is no inexpensive repair path for your saw using a new motor. Motors are not cheap. A new quality Leeson/Baldor 2HP will cost $400+. Even a cheap Chinese made 2HP motor costs $250+. Your only hope of cheap repair is finding a used motor, or a damaged tool with serviceable used motor; and using it to repair the saw.

Best Luck!

Thanks for a fantastic reply!
I have reached out to the Harvey corp and will follow up when I hear back. You are right, the mounts look very much the same.

The information about the welding may be an option, i did not think that was possible without harming the windings, great news. I will search for a motor also.

It is sad that many companies use a proprietary motor or other part, then don’t continue to support the tool. Good luck with your journey.

What is the diameter of the motor and the bolt pattern?

LOL
Just opened the PDF manual for C200 TS. Was guessing before.
Be shocked if the C200-106 motor would not fit your P0715P. Why?

The C200 parts list has the item number for motor as 106. The Grizzly motor is item 106, and they look exact same. Furthermore the arbor casting is also same. The arbor casting is critical part and expensive piece to engineer differently, especially when old design works.

When you see this kind of item number similarity on drawings between Asian made tools, it is not a coincidence. Spent decades working with off shore tool mfg. Engineering and CAD labor in Asia is in short supply, and well paid compared to rest of staff. Marketing teams will reuse existing documentation as much as possible to reduce costs to create new/different ‘customer’ manuals. Identical individual item numbers on Asian tool is big hint to know when Jet, PM, Grizzly, etc; all sell machines made from same original design drawings; even if made by different mfg. Could share tool cloning stories from many decades in past that would make your head explode, but it wonders too far off topic.

Cheers!

short follow up:
Had a quick reply from Harvey Machinery:
”Thanks for reaching out. I’m sorry that Grizzly has stopped ordering G0715P from us for a long time.
This motor is discontinued since there’s no orders. Really sorry for not helping you out.
Sincerely yours,
Jessie”
**

This does give me hope that they still make that motor for themselves.
I followed up with another request specifically asking if the Harvey part 106 (for C200 tablesaw) was same as Grizzly part P0715P 106 .
I requested a price and availability of Harvey part 106.
Will post back when I hear.

Cant get them on the phone. Emails to customer service is only contact.

Last reply from Harvey Machinery:

”I have checked with our engineer that the motor of C200 can not fix Grizzly G0715 saw.
Our motor supplier stopped this model because we are not ordering it any more.

Sorry again for not able to help you.

Sincerely yours,
Jessie Wang

Guess I will be looking for a motor and get the brackets welded to it. May be a couple of months before I get anything done on this now. If I can’t find a used motor i will just part it out.

Have your say...
