G0516 Pulley/Belt question
Hello, I'm new to this forum but have been reading it almost non-stop since I found it last week! Have found many answers to questions I had, but one question I haven't been able to find an answer to...
I recently purchased a Grizzly G0516 which came with a 31" belt. It was all I could do to get it in place on the pulleys and now I can't get it off to change speeds. The motor is rigidly mounted, no hinge, so how does it get out of the way to provide slack? Am I just being dense here, or did they send me a short belt? Should I go with my instinct, cut the belt and replace it with a 32 or33 inch belt?
Thanks in advance for any advice.

Re: G0516 Pulley/Belt question
the belt tensioner is right above the motor between the coged pulley and the v pulley
losten it and all should work out also consider the v belt rides over the top of the tensioner and not under it

Re: G0516 Pulley/Belt question
Thank you for your reply. I can see the belt tensioner and it is not the issue. I have it completely loosened and not even in contact with the belt, yet I can't get the belt off the pulleys or into another groove.
After close examinaton, seeing as there is no way to move the motor to provide slack, I am convinced the belt that came with the machine is just a little too short. Perhaps someone grabbed one out of the wrong bin or something.... No matter. I've decided to replace it.
Has anyone measured the circumference of the belt on their own G0516?

I think the belt on mine is also too short.

Re: G0516 Pulley/Belt question
Sorry to revoke the old thread, but I recently experienced exactly the same problem. The belt is already so tight as-shipped that belt tensioner is not even needed. I find it impossible to take the belt off without damaging it.
Did anyone have luck with replacing this belt with 32 or 33" as suggested by Longstride?
I researched it a bit and found that the belt is of 3L type/profile. I have found this: "Gates TruFlex - FHP V-Belt" which is 3L, 32" (33" also available), for a very reasonable price at o'reilly. Would this work, or do I need a stronger belt that this? There are stronger (and more expensive) versions of 3L by the same manufacturer, but I am not sure what would be strong enough for the machine. The belt desription says "Gates Truflex(R) V-Belts are recommended for lower horse-power lawn and garden equipment, heating and home air conditioning drives, light-duty appliances, shop and miscellaneous fractional horsepower applications."
But this is vague - if I remember correctly, G0516 is 3/4HP motor - would that be on par with 'lower horse-power lawn and garden equipment etc'?

Re: G0516 Pulley/Belt question
My money says it will probably serve perfectly well. Unless you're taking some serious cuts, it's unlikely you'll be using much of the 3/4 horse at your disposal. And, should the belt fail, you'll know to step up to the next strongest. Failure of the belt would most likely be nothing more than an inconvenience.

Re: G0516 Pulley/Belt question
I wanted to update everyone interested in this topic - today I bought both 32 and 33" belts, as suggested. Both of them are now too long - the belt tensioner does not have enough travel to tighten them. I removed the original 31" after applying great force (scary), and reinstalled it for slow rpm. But it still does not feel right. The belt tensioner is not even needed for 31", but 32" is already too long. It looks like 31.5" would be the right length.
Re: G0516 Pulley/Belt question
Converting 31.5" to metric, it is a suspicious 80 cm! I bet you need a metric belt for this machine.
If NASA could lose a Mars spacecraft because of failure to properly convert SAE to Metric, it makes sense that Grizzly might have made a similar mistake! A little less serious, though...

NP317, great insight, thanks!
I will look into metric belts.

How about making and installing a larger
diameter idler pulley on the tensioner plate
to allow using the 32 inch belt
It looks like there is more then enough
clearance to do that in the above picture.
just a thought.

Re: G0516 Pulley/Belt question
ken572, thank you for the suggestion.
I will look into that - I don't see a problem, as there is plenty space inside.
However, I was hoping for a quicker/easier solution, this is why I was looking for slightly larger belt.
Contrary to my intuition, 32 is too long, even though the travel of the tensioner is quite long - I was not expecting that 32 would be so long that the travel would not cover that.
For a new tensioner, I need to look into available parts or make one myself.
