Default BandSaw Tension Problem

My blade adjustment screw on a Grizzly G0555P Will not loosen or tighten. I am wondering if the adjustment screw got bent or the threads messed up. The picture below is not of mine but is for reference.

On my saw the screw is almost bottomed out to the frame and am guessing that if the blade was tight and then the quick release lever was pulled down to apply tension the screw bent? or the threads got messed up?

If that is the case what is the correct way/easy way to get the old screw out and the new one in?

Dont have that machine so this is not specific..
A threaded bolt shouldnt be so soft that it would compress the threads just from that short lever throw.
Are you sure there isnt a grub screw locking it in place?
If not then its either been cross threaded on the way in, or it has corroded in there.
Some wd 40 lubricant and brute force is your only real answer. If the head strips then youre down to pipe grips, and if that fails its a centre drill and screw extractor.

Actually, Widdley Diddley 40 isn't that good.

Try a 50-50 mix of acetone and ATF. (automatic transmission fluid)

In a series of tests performed by several machinists some time ago, NONE of the proprietary products on the market came close...even though they may cost several times as much.

I buy a gallon of each and mix at a 50-50 ratio, put some in a plastic spray bottle and it lasts for ages. It really does work.

OK, fess up...which one of you clowns stole my sig? It was right here a second ago.

I only use Kroil penterating oil. Try a can of it and I think you will agree. You use so little it last a home DIY a long time.

PS- I like the spray best.

so mix batches by the 250 ~ 500 ML ..
Keith was right on target...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Kroil is definitely an outstanding product. It WILL break out a rusted bolt if allowed to work. Wasted Dollars-40 won't even come close.

As for the cost of Keith's concoction, a gallon of Acetone is around $18 (USD), ATF can be had at discount stores for around $2.50 a quart (any generic will do).

Like Stick says, mix small batches as needed.

$28 for TWO gallons is a lot more cost effective then a $20 a gallon product like WD-40, and you'll get better results.

I learned a long time ago to keep raw components around. There are a lot of "mixtures" that use the same ingredients, that, if combined in the proper ratios will do a whole host of chores.

I got tired of having my expensive gun barrel cleaners either dry up or go bad. Small bottles were too expensive and larger bottles didn't stay fresh.

I started using a homemade solution (Ed's Red Gun Cleaning Solution) that has been around for decades. I Just keep the raw components around (and use them for other things) and mix up as I need it.

Hi, sorry I missed you. I have gone to find myself, but if I return before I get back, please ask me to wait.

Seems like we're concentrating on freeing up the screw and you may have other problems...time to get the ole magnifying glass out and play Sherlock Holmes...

Maybe a picture of yours with closeups...?



...but if you need to make a penetrating solution, I recommend "SnorkSnot"...see picture below of the label...

That 50/50 mix of acetone and ATF is a real winner...and as Bill suggested, mix up as needed and keep raw materials available for other uses...

Not sure what is stuck...#33 or #131 in parts diagram (back of your manual)...? 131 does have a set screw to lock it in place. If 33 is stuck, bottom nut #39 could be the culprit. Typically, adjustment should be made disengaged, then engage to see result. Maybe threads might be damaged in 39 from adjusting under pressure...? Is 131 not adjusted properly not letting you making further adjustments...?

You might also try taking the blade off the saw in case there is too much pressure even when disengaged...see if screw loosens up...
