table saw squeals and blade stops when ripping wood

When I am ripping wood using the table saw the headstock squeals and the blade stops.
This was a gradual thing.
It seems like the belt is slipping when under a load...and then the saw blade stops turning.
Would putting on a new drive belt fix this.
I have a 1962 Mark V with a 1 1/8 horse motor.
Thanks for any help.

You need to do a lub, oil and filter like pit stop and then BEFORE you make any more sawdust do a complete table/fence alignment. Then check to make sure you have a sharp rip blade installed.
Unless you are ripping 4" oak, you should not have these symptoms.

if you still have the gilmer drive the clutch could be slipping. here is an adjustment for that posted by billmayo I think.
Good luck.

I can't find the adjustment procedure on your post Mike. Can you please tell me where it is?
Thanks

If you have a '62 1 1/8HP Mark
5' THERE IS NO CLUTCH.
Have you ever adjusted the poly-v belt tension?
Also a true rip blade works wonders.

I didn't think the POLY V was standard until 64

This I why I suggested checking on the gilmer.
If I'm mistaken please excuse me.
I am trying to find the post on the gilmer rebuild.

Bill talks about testing the gilmer clutch.

Easy to understand the confusion.
A couple of 'paragraphs' above the 1964 one is this.
1960 to 1963 Brown/Gold/Tan/Anniversary Model- The introduction of the Poly-V drive system (the inside of the top belt is a serpentine).
I believe in 64' they went to gray. Never mind, that happened in 63!!!

I have not adjusted the polydrive. I will look up that procedure and try that....I also need to clean & lube it as the first person stated in his response.
I found the statement in the shopsmith serial number site you referred to regarding the polydrive where it states:
"1960 to 1963 Brown/Gold/Tan/Anniversary Model- The introduction of the Poly-V drive system (the inside of the top belt is a serpentine)." .....This is what I have.
The serial Number stamped on the circular steel plate of my shopsmith is 371598. The plate also says "Mark 5" along with "Yuba power productions Inc. Cincinati Ohio"
Even considering I got 10 years on this unit......it is still in better shape than me.
Thanks everuone for all your help.

Please also perform the fence alignment as Dusty suggested. I was having this problem as well as burning wood during cuts and found I was using excessive force to rip material (excessive force with any tool is always dangerous).
Aligning the fence did wonders!! Now I always have clean easy cuts and no bogging down. Based on the age of your machine you may want to either sharpen or replace your blade as well. Add a new/freshly sharpened blade to the fence alignment and all of a sudden you have a new machine!!
Good luck and keep us posted.

I found the gilmer rebuild thread by mickyd

Probably not needed here but I said I would try to find it.
There is a reference to it in this thread
https://forum.shopsmith.com/viewtopic.php?t=3078
which is also a great thread for general rebuild and maintenance issues
Thanks again to mickyd for all this shared information.
