have a 64 duoglide panhead. stripped it to frame and about to sandblast it.. here is my issue. the guy who owned it before me was a hack. as disassemble started.. more and more finding things that were forced to fit and hacked onto the bike. broken chuncks missing from forks, front end etc. the frame though where the swing arm goes has an axle or a rod that goes through them both. with and without swingarm attached this is what im dealing with.. it does not start threading into frame part of the swingarm mount until its half way through. it also does not bottom out on the outside of it (as picture #3 shows) i feel like all the threads should be hidden inside the frame... (pic # 2) do you think maybe this hack just threw one in that doesnt fit? should it be flush (pic 3)? should the threads go all the way in (pic 2)? or should it fit like that? first pan.. didnt notice this issue until playing with it all and getting familiar. thanks for any feedback

 

your not alone in that problem - have a 66 in the shop that has the threads stripped all the way out -

The fix - cheap way - and i do not care for how the fix is done - a replacement swingarm axle that has a self threading thread on it comes in different oversizes 1 / 2 and even a 3 i think - and what happens is, the axle bolt is air wrenched in < reason i dont like it

i am now looking at helicoils or even time serts as a fix much harder to do as the left side is actually in the way and the right side in a resto you will see the repair a bit still not sure what path i am taking i have in the past just used the re thread like most do and it does the job -

when you replace the swing arm bearings / races with the dents and seals we have a tool using a long bolt and nut and tighten a nut with the swingarm in hand, hit the bolt and keep turning the nut it till it does not become loose after hitting it with a brass hammer - this way a week into riding the back end is not feeling as if its got a wiggle -- johnjzjz
