Hello,
I recently bought a 24" Covington used.
I am having a real hard time getting the blade off of the saw and putting a new blade on it.
I made a spanner wrench. When I used it, it just bent the wrench.
I bought a spanner wrench from covington. It also bent.
I'm not sure what I am doing wrong and would really appreciate help getting the saw up and running!
Thanks in advance.

If anyone has a link to a covington 24 video tutorial or how to change the saw blade that might be really helpful!

Are you turning the nut the correct direction for the threading?

Are you turning the nut the correct direction for the threading? That's a great question. On my other saws, the nut goes the opposite direction as the blade turns. I have tried both ways and cannot get it to budge! |

I'm guessing it is cemented (literally!)in place. A penetrating oil applied a couple times a day and allowed to soak for a couple days may loosen it up. Not sure if you have access to a socket large enough but if you do and can get a breaker bar and a length of pipe on it you should be able to crack it loose. If all else fails, heat may be your last resort (careful you do not ignite the oil!). So if none of those methods work (and I would try them in the order I put them down) it's time to cut the nut off. Grab your Dremel and a cut off wheel and cut as deep as slot as you can and if possible a slot on each side (or even 3 or 4)then a cold chisel and a wack with a mallet. Hope this helps.

To loosen the nut on any saw you turn in the direction it spins.

I purchased two Covington 20" saws some years back and both had the same problem. I tried soaking with Kroil for several days with no luck. I eventually had to heat the threaded flange nuts on both saws that holds the blade on to make it expand enough to let loose of the saw blade.
If you try this, to reduce the risk of a fire hazard just make sure to REMOVE ALL OIL and CLEAN ALL OIL RESIDUE OUT OF THE SAW before using a torch to break the flange nut loose. And even after doing that I still draped water dampened towels down the inside sides of the saw's oil reservoirs and underneath the blades in the bottom of the reservoirs just to play it safe. Old oil can eventually dry to a hard substance in a saw that has sat unused for a long time, but it can still be flammable. So if possible it would be best to do this outdoors.
Good Luck!
