34-444 blade height adjustment causes arbor pulley/belt to hit the underside of the table top

I was here a few years ago with a different problem (could not level the splitter) on my table saw. I thank everyone who helped me fix the problem you all were very helpful.
Now I noticed a different problem…
The arbor/pulley hits the underside of the top. I can turn the height wheel CCW and lower the blade a little that it won’t hit. It seems to me that there should be a stop to prevent this from happening. Can anyone help?

Is this new? Has something happened or some changes made recently that might cause it or contribute to it? New belt for instance? Have you had a significant kick-back that might have changed some alignment or broken something somewhere?
I assume this is a contractor style saw. If so, can you try adjusting the position of the motor or the belt length to change the angle of the belt between motor and arbor? Can you shift the position of the arbor pully on the shaft a bit to maybe make it clear the underside of the table in a better place?
bilyo...Thanks for the input...
This is a new problem I noticed when raising the blade. I changed the belt to an Accu-Link right after I got the saw (about 2 years ago).
Yes, it is a contractor saw. I'll check to see if the arbor can be moved. I measured the belt compared to the old one, but I am sure that I can remove a link or two and see if that helps.
I was hoping that maybe there is a stop pin that would limit the height movement of the arbor. I can't find such information on the internet.
I was thinking that adding a link or two would allow the motor to lay down a bit more and change the angle of the belt downward. Depending on where exactly the rubbing is occurring, it might help.
I had this model saw in my shop for several decades, mine being a mid-1980s vintage. If I understand your problem correctly, the arbor is rubbing on the bottom of the table when the blade is fully raised. My old saw did the same thing. Makes a heck of racket, doesn't it? I simply (and eventually) learned to not raise the blade fully while it was spinning. Mind you, I'm talking about backing the elevation wheel off maybe a 16th of a turn. I never thought to investigate whether there was a stop that could be adjusted. I suspect it's something endemic to that particular model, but perhaps the Arbor link belt rides a bit higher in the arbor pulley than the traditional v-belt did.
Not to mention the burning rubber smoke and smell!
You may have something there. I did not look at the new belt to see how high it rode on the pulley. I used the backing off the method you talked about and it does work...maybe it is supposed to work like that...:(
