I've had issues in the past with the #3 phillips for the screen on the flywheel. I've soaked these for a few days and hit them with the manual impact. Four for 4

Niiiiice. 

 

That manual impact driver was a recommended purchase by the folks here on Redsquare several years ago when we restored my 1974 C160-8 Cinnamon Horse. 

EXCELLENT purchase.  

Whack! To tighten. Then loosen. 

Repeat. Remove.

Sadly, mine was a hand-me-down from the late 40s and doesn’t support sockets. But it DID come with a fat blade for slotted screws which has been terrific on a lot of old furniture work. You have a lot more control than with a powered impact driver. 

 

Lots of good info in these posts!  

 

Tightening to loosen.  That’s huge!  Shock the threads, but don’t gall them.  It was a trick an engineer who came from lab work taught me a long time ago.  It works great with pipe threads especially.

 

Impact drivers.  They are cheap and I use mine often.  Sometimes however, I’ll hang a large box end wrench on my closest screw driver handle and give it some taps with a small hammer or dead blow.  It typically does the trick and costs no money if the tools are available.  I’ve never broken a screwdriver handle using it as an impact, but I have broken plenty using them as chisels.

110%. I just did this with the remainder of a broken cab bolt.

One of the techs at the GM garage I worked at 25 + years ago used to tell us..

You can almost never loosen it, but you can almost always tighten it. 

 

Then loosen. Then tighten. Repeat. Repeat. Repeat. Repeat.

 

What a cool trick. I've even seen a guy use that on the plastic fasteners for a plastic grille.
