Ok, showing my mechanical ignorance here. Just cleaned out my Covington 10 inch saw and now it won’t take a load. Just a little pressure and the blade stops. Removed the top and tightened the blade as much as I could but now I’m thinking the pulley is loose. Did the pinch test and there does seem to be too much slack. So how do I tighten it up?

I was going to suggest avoiding processed foods. 😄

I have a Covington 14" saw and don't see how cleaning your saw changed any settings unless you removed the glide and blade for cleaning. If the blade is tight you should check both the shaft and motor pulley if they are not keyed so they don't slip. On my machine the belt can be tightened by raising the motor up slightly. I would then check the screw drive and make sure you exert the correct pressure on the blade. Finally, I would make sure the blade is sharp.

When I was rebuilding my home-made saw, I needed a belt to be tighter and fabricated an idler pulley using a pulley salvaged from a junk washing machine. You can see it in the photos in the diy equipment section. The pulley stretches the belt circuit enough to tighten everything. It is just a plastic pulley with a bushing rotation point but it has run hundreds of trouble free hours. Of course there are pulleys that can be adjusted to achieve slightly different diameters (hence tightening or loosing the belt), but there is only so much you can do with them. (one side is threaded on the other side and can be adjusted inward or outward once the set screw is loosened).

I put on a new blade after cleaning and I’m hand feeding so not an auto feed issue. When you mentioned that changing the height of the motor will tighten the pulley, that made a light go off in my head. I remember that’s what I did a few years ago when I got a new belt. I’m going to give that a try in the morning and keep my fingers crossed.

Couldn’t move the motor any more to tighten belt so bought a new belt and everything is back to normal

Mapleann, I removed the bolts that came with the machine and replaced with longer bolts with the same diameter. This allows for adjustment when the belt stretches. I also like the idler pulley that Peruano suggested.
