help to remove (rusted) screws from airbox..

Was hoping to change the air filter today, but 4 of the screws in the airbox (Fi 800) are quite corroded and don't seem to want to budge. Grateful for any advice on how to shift them. One of them is at the front of the box and pretty awkward to get to. Many thanks

 

Use WD40 and a reverse (Easy out)

Good luck :thumb:

 

use a impact hammer and soak for at least 2 days in penetrating oil:dizzy::hi2:

 

I'd try an Alden Grab-It with a bit extension. Requires a drill and will destroy the head of the screws. It's ok if the heads are stripped.

 

I had the same problem with mine. I used an impact screwdriver and they came right out.

Another method I've used to great success is with a decently sharp small cold chisel and hammer (this only works if the screw head is above the surface obviously) You come in at the screw head from the side carefully working around in counter clockwise fashion. Build yourself a little shelf by digging into the head of the screw with the chisel. Great method to try if the head is stripped, or even as a preventative to stripping the screw out. I've saved numerous fasteners. The head winds up a bit nicked but the + recess stays intact.

The regular impact driver method mentioned above is great, but I would hesitate to use it if say the screw is in something plastic like a air box.

 

What aboot grabbing it from the side with a small pair of vice-grips (pressure pliers)? You just have to get it broken free and then its down hill, or possibly up hill from there. ; )

 

I never even knew there was a difference - something new to learn every day... Just ordered a JIS screwdriver.!
plan of attack: soak for 48 hours, try the new screwdriver, then an impact driver, then alden grabit or an easy-out, then chisel, and if all that fails - there'll be ample swearing followed by a plea for more help!

 

The J.I.S. screwdrivers are awesome. The screws on japanese bikes with the little dots on them(like on carb bowl screws) are j.i.s. Harbor Freight also sells a cheap set of left hand drill bits that have saved me a lot of hassle.
