Replacing v belt on grizzly table saw

[Mark Ader]

Hi all. I'm replacing the 3 v-belts on my grizzly G0690 cabinet saw. I ordered the belts from Grizzly after they confirmed the correct size of the part.

The issue I have is I cannot get the belts on both pulleys following the owners manual instructions for detensioning the existing belts. Anyone have this problem? There is a bolt to loosen that allows the motor to move up about a half inch. I have done that I still can't get the new belts on ANY of the 3 positions.

I sent an email to Grizzly asking the same but haven't heard back yet. Any tricks, tips, or something I am overlooking is appreciated.

I have a 691 put have never changed belts.

1/2" sounds on the low side. See if you can get any more movement.

If not place belt in outermost groove of one pulley. Then place it partially in groove of other pulley. Try to rotate pulleys so that belts get pulled into place.

If this works you will have to use a similar method to try shifting the belt inward. Shift belt qhile turning pulleys.

Hope this helps.

Call Grizzly tech support. I have found them very helpful.

[Jeff Miller]

I can't remember for sure but it seems I tilted the saw to 45 degrees to do it .

Just a thought.......but I did get them changed.

Good luck

Well I contacted grizzly tech support. They confirmed I have the right replacement belt and have been responsive to my questions. However, I still am unable to replace the belt. Going on 2 weeks with no tablesaw. I have several thousand dollars of grizzly machines in my garage and am at my wits end. I have asked for a refund of the belts I ordered from grizzly and plan to go the linked belt route.

There simply is not enough slack to roll on the new belts.

[Peter Christensen]

Take the Grizzly belt to an automotive parts place and have them give you the next size up. You could even get the next up from that in case it needs a bit more. Take back the ones that don't fit.

[Yonak Hawkins]

Mark, if you do plan to return the belts, I would recommend segmented belts for your table saw. I have had luck with them for my Jet cabinet saw .. really cut down the vibration.

I have 3 link belts on a G1023, did it before hearing I wasn't supposed to do that and they've been fine far as I can tell. If I were doing it again I'd probably use AX

They're supposed to not take a set like the link belts but are less expensive and might be a little quieter due to less air turbulence. As far as matched sets, modern manufacturing tolerances are likely tight enough that matched sets aren't really required. I don't run my G1023 belts very tight and have no noticeable slippage.

I'm not sure where this truism comes from. I have link belts on almost everything. There is some thought that they are not heavy duty enough when industrial use is their birth place.

Belts for multi-belt sleeves need to be fairly close in size but, for a 10" tablesaw I know many people just run one when changing them out. I'm not recommending this, just stating a practice reported.

[Ronald Blue]

So will the belt even partially hook on the pulley? There is a technique called rolling the belt on. You rotate the pulley and roll the belt on. You start at the outer grrove and work it in to the inner groove. You only need to get it to start to catch the groove to make this work. It's not unusual to have belts that seem to short. If you get the next size longer at the auto parts store you most likely won't be able to tension it. 1/2" of travel on adjustment isn't much. You might also see if removing the tensioning lock bolt will allow the motor to move closer to the arbor pulley. Good luck.

[Mark Ader]

Update: I returned the grizzly belts and ordered regular v belts at 3/8" x 25", the exact measurements of the original belts. Still no luck with rolling them on. I can get one belt on put can't get the others. Anyone who lives in Atlanta want to make a few bucks by doing this for me? Please PM.

I am sorry for your frustration with this. I would be glad to drop by but, I'm out on the left coast. I hope a nearby Creeker will chime in and help you out.

Grizzly youtube video appears to be lots of slack maybe a hint there to help

I replaced my belts with notched v belts with no problem. I actually only use a single belt now because it seems to reduce the vibration down to almost nothing and haven't had any slipping issues. Rolling the belts off was pretty easy. That said, are you sure you got the right belts? If memory serves me, our saw uses Z profile metric belts.

[William Young]

Just a question; Is it possible that there is some sawdust or chips packed in somewhere that is keeping the motor from moving far enough to give the slack you need?

[Ronald Blue]

What William says. Or can the bolt that locks the motor for tensioning the belts be removed to get more travel from the motor? I'm confused on the statement that you can roll one belt on but not the others. Using this technique if it rolls onto the first groove it should't be a problem to step it back to the furthest inside groove.Then repeat with the second and third belts.

[Phillip Gregory]

Make sure to loosen the lower nut on the motor mount plate to completely de-tension the motor. Move the motor upwards and then tighten the nut so the motor weight does not cause it to sag downwards and apply tension to the belts. You can easily remove all 3 belts that way. The set screws on the arbor sheave on my Shop Fox W1820 (aka Grizzly G0691) loosened and I had to remove the belts to tighten up the set screws, and that's how I did it.

a few things to consider

1. You may have pulleys that can run 3/8" belts or 1/2" belts. If so you will need more than 1/2" of motor movement to install.

2. Two of 1/2" belts would be plenty to replace three 3/8" belts but the size would be bigger. Also since the pulley on the arbor is usually at the absolute minimum functional diameter 1/2" belts may not work out well.

3. You may be doing something wrong if you have only 1/2" of adjustment. Maybe that is from the midpoint to the shortest point. If there is room to extend past your previous operating point you will definitely be ok with 26" belts. Try 26" and it will probably work out fine.

4. To get more movement, just loosen the motor mount bolts till the motor can move further.

The stock sheaves are designed for metric SPZ section belts. The belt the G069x series uses is the SPZ 625, which is 10 mm (0.39") wide, 8 mm (0.31") deep, and 625 mm (24.6") long.


2. Two of 1/2" belts would be plenty to replace three 3/8" belts but the size would be bigger. Also since the pulley on the arbor is usually at the absolute minimum functional diameter 1/2" belts may not work out well.

You would need to replace the motor and arbor sheaves, and due to the small diameter of the arbor sheave, use cogged 4L or A section belts if you want to run a 1/2" wide belt on these saws.


3. You may be doing something wrong if you have only 1/2" of adjustment. Maybe that is from the midpoint to the shortest point. If there is room to extend past your previous operating point you will definitely be ok with 26" belts. Try 26" and it will probably work out fine.

There is only about 1/2" of vertical adjustment in the motor due to how the motor mount is designed. The motor mount has two bolt holes. The upper one is a standard round bolt hole that serves as a pivot, and the lower one is semicircular that allows the motor to move up and down relative to the trunnion. There is about 1/2" of vertical travel.


4. To get more movement, just loosen the motor mount bolts till the motor can move further.

That is only true if there is any binding preventing full range of travel. As above, there isn't a bunch of travel, but in my experience, there is enough to get the belts on and off as I have done so on that saw.

I see this thread is a bit old but have you tried warming up the belts a bit say in a bucket of hot water or carefully with a heat gun? Might try some lubrication that can be cleaned off after?

Hopefully the OP hasn’t been scratching his head over this for the past year.

[Mike Kees]

Maybe he just bought a new table saw.

[Lee Schierer]

Remove the bolt completely ad you can probably get enough movement to get the belts on.
