Topic tags/keywords: table saw arbor nut

After reading the posts about the arbor nut being stuck, I finally got my bade off my table saw. But now the arbor wrench is jammed so tight on there I can’t get it off. Any suggestions???? I’ve tried WD40 and a hammer.

heat it with a bottle torch. (the wrench – not the nut).
if your hammer method is not working ~ you need a bigger hammer !!!

WD-40 is not a penetrant – and will not work on two pieces of steel that is only forced together.
heat and coaxing it apart with force is one way.
if you have an identical wrench, sacrifice the stuck wrench and cut it off
with the angle grinder. (the wrench – not the nut).
a piece of pipe, socket, or something that the nut will fit in would provide equal support
around the nut while tapping it out with a hammer.

Where is it stuck… on the arbor? If so, stick the blade and nut back on there so you can apply force in the opposite direction to back it off and break it loose. In the future, just use a wrench on the nut, not the arbor (just use a 2×4).

I’m assuming that it is one of those flat stamped steel wrenches. If so, it is likely that it is a much softer steel than the arbor nut and since it is stuck that tight, it is probably chewed up and deformed anyway. I suggest that you cut it off and buy a new one. Hopefully your arbor nut is OK.

If brute force isn’t working, it’s because you aren’t using enough.

well – since Lindz, the O/P hasn’t checked back in, he has either fixed
the issue or broke it beyond repair – who knows. . . . . . .
