What a Pain in the butt still didn't get it off so frustrated if anyone has suggestion please thanks
Thanks i was trying not to take the down pipe off but looks like iam gonna have to Ive been PB Blasting it hopefully today i can get it offBreak out the dremel, you start by cutting a slit in the head and using a flat blade screwdriver, or you can roughly cut it to a hex shape and hammer a socket on there, or you can cut the old CPS out of the way to allow more room for vice grip.
Someone else had good luck with one of these:Gator Grip ETC-200MO Universal Socket - Amazon.com
Also removing the downpipe if you haven't already allows better access.
Heating generally causes expansion in metallic objects (though it will encourage the absorption of the penetrating spray) while cooling promotes contraction, though you had damn well be sure to protect the surrounding area, and the wiring harness in particular, from the heat of the flame or you could, potentially, damage other associated/surrounding components.I'm not entirely certain of the positioning of the crank sensor. But if you can safely get a heat source under there like one of those mini butane lights and heat up the screw. Sometimes the heating then cooling will fracture some of the corrosion loose.
The NG900 didn't come with one. For whatever reason the exhaust manifold has the protrusion off the front that you can drill and tap for an 8mm stud so you can bolt a heat shield on. I did that a few years ago. Cast iron is pretty soft and drills very easily, even with a cordless drill.Mine has no heat shield either. After looking at many pics, I don't think it came with one.
