   I've seen it happen to other Delta planers but not as bad as you describe. Try a better loctite like # 262.

   Good suggestion.  The LockTite I have is supposed to be for nuts, screws, etc.;  it is blue.  As I recall, the tougher version is red.  I checked the LockTite website and they don't list a 262; they show a 242 and 271.  I'll see what Lowe's or HD has on the shelf.Bill Arnold - Custom Woodcrafting

   Bill,

   If the pulley or the nut ran loose for a while, and especially if some of the components are aluminum, the pulley, nut, and/or the shaft threads may have worn and they are now too loose to tighten properly and will have too much clearance for a locking compound to hold. 

   Also, check that the pulley still has a key or intact splines to lock it on the shaft, if the pulley can rotate that could cause the nut to loosen.  If all else fails, tighten the nut, drill all the way through it, and drive in a roll pin.  Drill all the way through the nut so you can drive out the pin, if needed, in the future.

   If you discover the cause and/or the cure, I would like to know what you found.

   Good Luck, John W.

   Thanks John, Rick & Dave.

   The pulley is still solid on the shaft, so no problem there.  The nut sits in a recess in the pulley and there is just enough clearance to get a socket wrench on it to tighten it.  Therefore, there is no access to drill through the nut into the shaft unless I do it with the pulley off.  In that case, there would be no sure way to know if the alignment of the holes would be correct, unless I'm missing something.  I'll try the red LockTite and if that doesn't tame the critter I'll try the nail set on the nut approach.

   I never bother with the  blue one. It's made to be loosened by hand. The red (mine is 262) will work the same way with a snall drop and if you put more, you need heat to get it  off. There's higher levels that have to be heated cherry red but that's more than you need. The pulley is cast iron and the red loctite will be sufficient to secure it. I'd say I have run across this a dozen or so times. Just seems to be something that happens easily with no real explanation, probalbly a little more vibration because of how the motor is placed.

   A lock washer?

   The parts diagram does not call out a lock washer nor is there room for one under the nut.Bill Arnold - Custom Woodcrafting

   Rather than going to the trouble of drilling through the nut and shaft, after tightening the nut, take a small nail set or punch, place it right next to the threads and give it a good rap. This will expand the nut a little and help keep it tight(along with the Loctite). Do it in two or three places around the nut.
