Bought a used 93 KDX200.
went about doing some due diligence on it( new chain/ sprockets etc)
Cleaned out rear wheel bearing, decided to replace them as they were rusted/ pitted.
Decided the swing arm needed some attention to be safe.
Took off the swing arm shaft nut and proceeded to to try to slide the shaft. Nothing. It spun by putting a ratchet to the bolt head( but was tight/ could feel resistance) Shaft would spin and spin but would not back out horzintally. Buddy said more than likely major corrosion to the races? or possibly bearings and thus wont let the shaft back out, if that makes sense.
Right now its on it side with penetrating oil. Will let it sit overnight or a couple days then try to basically sledgehammer it out.
Thoughts? if that doesnt work? or other approaches? thought about using a sawzall to cut the shaft but dont have a lot of space on one side unless I take the engine out.
Heat to the frame or swing arm? not a big fan of that as I've never done it. Dont have that type of heat ( other than a small MAP torch) and dont liek the idea of heating the frame maybe possibly weakening it( i guess?)
