Can't Remove Knives From My DW735 Planer

Featured Replies

The allen screws are frozen. I stripped on screw and then stripped the allen t-wrench that came with the machine trying to get them out. They are dead frozen, most of them. Anyone have any ideas how to get them loosened up? I currently that some WD-40 soaking on them for now.


I need to get these out so I can put my new knives in!


Help!

John, first, grind a fresh end on your allen wrench.  If you can, put the allen wrench in the set screw and tap on the with a hammer as you apply steady pressure to the allen wrnech.  Sometimes the taping will break the threads free.  If that doesn't work, try C4.  It works every time.

Thanks Ron, I'll go out and try now. On a side note I was over at Accu-Head, and am seriously considering it if this pans out to be a bust and I got to take it into the service department.

Ok, hex heads are rounded in the screws.


Any more ideas?

   Simple tool kit:



Allen headed socket.    Looks like an allen wrench stuck into a socket,  for this size, a 3/8' drive will do


Extentsion for the socket.  Knuckle saver



Adapter to attach the above to an impact type drill/driver.  



Assemble the above, set drill for Impact, and loosen bolts.    Use a ratchet if needed, after the bolt is loose. 



Note: keep a rare earth magnet on the allen wrench, those bolts like to "fly away" on their own.   DAMHIKT.....Tongue.gif

I tried it Steve, I really thought your idea had some great traction to it, but my allen heads are just too buttered up at this point. Thanks for the great suggestion. I am leaning heavily towards just purchasing an accu-head. Just part of doing business.


Ron, I tried your suggestion that we had talked about over the phone and no luck there either. I might not have the right technique or what not.

This sounds like an opportunity to but an Accuhead.

At the factory, I sometimes had to drill out stuck bolts with a left-hand drill bit. "Most" of the time the drill would catch the bolt and back it out. Just be sure you're centered and drill straight. A little heat from a pencil torch helped too.

John, I have removed stripped out screws with one of these.



I most likely would work for your situation. Of course you will be replacing all of the hex head screws anyway.

John,


I have read about this, in anticipation of changing blades on mine. Here is a link to another forum with a bunch of suggestions.

Just checked the Dewalt service page and they are now using Torx head bolts. They have an upgrade kit of bolts and wrench for $17.47. Part# 5140067-11

Stopped by the local Fastenal store and picked up replacement screws for my Dewalt 735. Their part number is 1139910 and they are $6.95 for 24 screws (M6 x 12 BHSCS). The tech there said they were equivalent to grade 8 steel. While I was there I inquired about a penetrating fluid. His recommendation was Loctite freeze and release. Not cheap $13 a can. Also picked up some anti-seize. Off to the shop to see how things go.

I've used wintergreen which you can purchase at drug stores. It's the best penetrating oil I've ever used and I've used them all.
