Angry How to loosen a stuck set screw?

Hi,

I am changing the bushings on the steering arm of a Volvo Penta 280 and I can not loosen the set screw on the arm that is attached to the steering fork shaft. The set screw got corroded and I can not take it out.

Any suggestions of what to do without damaging any parts????

Thanks !!!

What is Kroil?
I was trying to avoid heat but I think that is the only way. The set screw is completely corroded and the wrench will not grab it.

Left fluted drill bit and run it in reverse in the drill motor. Make sure the drill bit is almost the same size as the threaded hole. Lube the set screw a couple days ahead of time. Or use an easy out.

lLeft drill bits are expensive and break when you try to remove a screw with them. drill it out dead nuts down the center and put a thread repair in it. It's not stainless steel is it?

Shock it with a drift and hammer a few times. Otherwise drill it out and use an easy out.

X2 on the PB Blaster. It works miracles.

Give it a good smack with a hammer and drift. Get a socket drive Torx bit and beat it in. Back it out with a ratchet. Works great for stripped allens.

Let it soak with the PB blaster or Aero Kroil for several days (and renew the penetrating oil) each day. you can use a heat gun, rather than a torch to heat it, and avoid any damage to surrounding areas.
