Air box removal seizes

[Mariner]

Anyone got any ideas as to removing the bottom nut on a s3 air box. Access is difficult so can't get anything behind it to stop the other side spinning. Cheers

The bolt should have a square head so it doesn't spin.If someone has replaced it with an ordinary bolt you can get a flat bladed screwdriver in from the other side (battery side) and lock the screw head so it doesn't spin.

Never had this problem but if you get a length of wire, coat hanger size or maybe a little thicker, hammer one end into a wedge shape the bend it near that end 90 degrees you should be able to put that end in beside the square head and stop it turning. Just an idea I hope works for you.

Thanks very much I'll try both. I think it probably still is the square bolt but has rounded enough for it to spin. I tried getting a screwdriver in from the bottom of the bracket but to no avail. Thanks again

Dremel.

I think Dremel wins. Tried the other two options.

What I've done in the past is wedge an alan key in there. Stops the nut turning.

That sounds better than my idea!

The Allen key as the first thing I tried but just couldn't seem to get a good grip on it

You dont insert the screwdriver from the bottom you insert it from above the battery tray,or were a battery tray should be if you dont have one on your scooter.
