I have a Dakota 4 that I purchased at a show already assembled. I can not get one of the screws that holds the blade to loosen up so I can change blades. We've broke 2 allen wrenches and a screwdriver trying to get it loose. Any suggestions besides buying a whole new assembly (which I'm not sure they even sell)?

Try a little heat on it,put a butane torch(or propane) on the head of the screw using a circular motion,do this for about 10 seconds then put allen wrench on screw and tap on it with a hammer,hope this helps,P.S. if your young make sure you have a parent help you.
Good LUCK ! Jeff Smith
Your quicker on the key board then me,LOL
Spray with liquid wrech then heat a bit with the torch.don't get too close as it is flammable
The allen blots are possibly metric and may be stronger than SAE grade.
Place a heat lamp on it for a couple hours. if that does not loosen it.
Buy a impact driver, this will allow you to hit the head of the driver with a hammer and jar the set screw loose.
You may also try a hammer drill with a allen bit in reverse.
Sometimes you can break bolts loose by trying to tighten it a bit.
My last resort would be a torch due to paint burning off.
The penetrating oil is a good idea, but with bronze fittings and steel hubs, I'd recommend dry ice to constrict the metal instead of expand it.
if the allen head is 3mm it measures .118 a 1/8 allen whench measures .125 it is .007 lager. take a pc. of the 1/8 allen about 1 inch long and put a lead on the tip. tap it into the frozen screw and remove with a tap wrench. just do the math on all other sizes.
I'll try those ideas. I already tried soaking in WD40. I thought there was something else, but couldn't remember what it was called.
Jeff, I wish I was that young again (I think), and know what I know now. LOL
I'll let ya'll know how it turns out.
I caught myself doing the exact same thing the first time I changed blades.
Probably left hand threads . Turn the other way!
PB-Blaster is a penterating oil that is just out of this world for stuck even corroded bolts. Spray and wait an hour and try it.
i used it recently to remove a transfer case out of a 86 k-5 took a few sprayings but it done the job. good luck
did try both directions. I got three out, I wouldn't think the fourth would turn different, but I did try it. LOL
My husband took the torch to it. Heat worked.
Thanks guys. BP
some times when the other screws are out the last one gets pinched. slowly loosen all the screws equally.
Parents,Husband,samething,LOL,Glad to here yougot it!
