GL1500 Swingarm Rot From the Inside

Post by superblod » Sat Nov 15, 2014 12:46 pm

I have a 1990 GL1500 in a thousand bits. As I have it stripped down that far, I thought i'd take the swingarm off to paint it. I got it off no bother, but it has a rather nasty rattle, as if it has corroded on the inside and loose rust is moving about. It looks to be in excellent condition from the outside. I am considering drilling a hole to get the loose parts out, spraying the interior with as cavity wax and then tapping the hole and fitting a bolt.

Has anyone any experience of this? The arm looks very good externally and if i wasn't being a bit over the top with painting wouldn't have removed it and found the rattle. Another thing to worry about!

Thanks in advance

That's now the swingarms normally corrode - whether or not yours is too far gone in order to salvage, it's tough to tell. The mitigation technique you describe might be a good idea for a known good swingarm, but without knowing the state of yours, and how much corrosion there is...I'd be hesitant to keep using it.
