Hiya Wizard, yes i did think about that but i also kinda destroyed the bolt itself
Guess my 22 spanner isn't very decent, i also bought a special lambda tool on ebay just to make sure i don't destroy the new one when installing.
If you had a perfect thread, would a pair of vise grips work to install? The reason I ask , if you chased that thread, I wouldn't think twice of re-installing it, however I would get a chasing tap , or take both to a machine shop and have both chased. Key to easy assembly and removal is to use something like Kopr Kote Jet-Lube of Canada | Kopr-Kote - Copper/Graphite High Temperature Anti-Seize
, I used this for over 30 years in some of the harshest environments, including gas heat treat ovens, mainly in the mining industry, high corrosive , where threaded fittings needed to be cut off with a cutting torch after 3 months, when using Kopr kote, 3 years later fittings would come apart. Used on stainless to stainless threading, prevents galling. Pay attention to the temperature rating, not all anti seize are rated for 1800'F, including some of Jet-Lube products.
FYI the adjusters for tightening / adjusting the chain, I use it on those bolts, due to moisture and possibly having the swing arm fill with water ( it has happened on this forum), I had the brake side seize on me( 2015 650 abs), luckily I didn't panic, liberal amounts of wd40, and a few others, getting a small amount of movement, tighten / loosen/ tighten/ more penetrating oil/ repeat--I worked it free. Cleaned the threads and chased the swing arm, put liberal amounts of Kopr Kote on.
