If i were you(again just my 2 cents) i would strip the parts(wheels/motor, etc) and make a 2x72 frame for it...Would be pretty easy to do i think.
 
Mike, you're right....remove the rear wheel, figure out how to solidly mount it to the motor shaft, position it a little rearward, line 'em up at the distance for 72" belts, and blammo! Would be a while before it gets outgrown, I would think.

That's a really good idea.

one thought I had was to add a fourth wheel set back and lined up with the current way it's set up. not sure if this would be that much easier than just building one.
 
I looked through a good search and found this model which appears to be your disc/belt model.

It's a discontinued model. If you look at your grinder I believe you'll find the motor mount bracket that's attached with the two knobs is an added part. I could be wrong but I believe someone added the DC motor and when they did that they mounted it farther back. I bet you can either move that bracket back or possibly forward but that's not as likely.
Any way, you'll likely have to modify it more to get it to take 60" or 72" belts.

thanks for looking into it, you're right someone most likely moved things around. the model number does say 6Z117, but it's a "6Z117a" and it appears to be a variant that I haven't been able to find much info on.

I think the wheels are original, and the original belt size. If I have to modify it (seems like I do) might as well try to go for 72.

Its a factory made grinder I found this one up for auction looks like it is missing the disk grinder part https://www.biddergy.com/detail.asp?id=131007&pic=1#img

boy finding info on old dayton tools is a bitch there has to be a source somewhere

Dayton is Graingers house brand. Dayton is also sold by other companies like Drillspot. Call Grainger. Their tech support is great and they will have the info or the will find it and call you back. No reason to rack you brain looking elsewhere unless you enjoy that sort of thing.
 
guys thanks for the ideas and looking into this strange grinder. I really appreciate the help.

I think the ideal thing to do would be to take off the 3rd wheel and mount it further back, above the motor, using bolted down steel tube.

any idea how to get this type of wheel off? there's a small screw on the other side but taking it out didn't seem to phase it... I really don't want to break it.
 
Get a screwdriver and pry off the e-clip, and a snap-ring plier or thin-tipped needlenose plier to remove the ring...wheel should slide right off.
 
looks like you only need to remove the center snap ring, I would guess if you remove the outer ring the bearing will slid out

I got a reply from grainger and it was the cover sheet for the newer model, I guess the tech didn't understand the word vintage LOL
 
The black outer ring or the one under the eclip?

Lol that's weird about their response. The only info I've found online is from past auctions. No one wants to admit the belt length of it. Easy to see why haha.
 
Did you call and speak with tech support? That is the way to deal with Grainger and you will have three ability to ask questions in a timely fashion. The model number is ask you need
 
Got the two clips off. Still won't come off.. there's a washer type bearing under the e clip that's keeping it on. Any idea how to remove it?
 
I would take a brass rod and have someone lift on the pulley and drive it through, if you don't have a brass driver then carefully use a 3/8 or 1/2 inch ratchet extension, there is probably gunk in there from age a little wd40 wont hurt
 
at this point it should just slide off though if it were new? I did pull on the wheel hard enough for it to move the whole machine
 
ya thats what I am thinking, it looks like it has moved enough to cover up the groove that the e-clip was resting in

edit- it takes a surprisingly small amount of dirt to stop a bearing from sliding off the shaft
