How do I get these oil separator screws out?


Recommended Posts

I have found that when dealing with tight allen head screws not to use a standard L shaped allen wrench.  Get a set that will attach to a 3/8 drive ratchet.  You can put more pressure and leverage on them that way.

That's why it stripped

 

You need a 4mm.  Might still come out with that.

yes. I need at least a .0012 larger driver tip. I didn't think there was that much difference between 5/32" and 4-mm ? but there certainly is. I need to remember what I'm working on.

4mm is still a little loose on these. The bolts (ordered from Subaru) don't seem to be of the hardest steel. I think mine were probably Loctite-d in, will try the Dremel trick, and couple it with an impact screwdriver.

The Lisle (craftsman is the same) impact screwdriver has a 1/2" drive on it. You can adapt this to an Allen socket and get them out that way. You have to use a good snap on allen socket, etc or you will chowder the receptacle.

 

I Usually just use a left hand drill bit - it's faster. Once the thread tension is released they typically back right out. Snap on sells a nice stub length mechanics left hand set of 5 bits that is really excellent.
