Stumped... please offer some insight

[puffine]

I began my orange ATC 70 restoration, but as soon as i got the engine out i ran into a road block. When i got to taking out the rear axle, one hub bolt came off without a hitch, however the other side seemed to be reamed on inside the hub and mushroomed slightly at the end. There is hardly enough bolt protruding to get a socket one and once i start to crank it the socket slips. Im puzzled as to how the previous owner even got the bolt on like that. When i turn the hub the nut rotates slightly as well???? I can take a video to demonstrate, it's very weird. Now i'm stuck and not sure how to proceed further, any suggestions? Do i have to cut it off and try finding a different axle? I would like to not massacre it if possible. thanks -stan








Sorry for so many pictures but i wanted to show the full grasp of this weird situation :S

looks like you have enough sticking out to get it. not to insult, but are you using correct metric socket. if all else fails you can try locking axle in a vise and use a chisel on left edge of flat part of nut thats facing up and strike with . youre not trying to chisel into nut but tying to use the chisel to turn the nut. sounds crazy but does work. if that dont do it, find someone with oxy acetylene torch, heat it up red hot and give it two quick shots of air 180* apart. all you wanna do here is remove some metal from the nut. do not go all the way to the axle threads it will ruin them. you should be able to remove just enough metal that a few strikes with and chisel will break the nut and it will fall off
good luck

You think you have an issue with that hub... Just wait until you try to remove the axle from the frame...

I had to cut the hub off my axle. One drop of water that's not cleaned outta these lil 73/74 70's will stick the parts together like welding after 40 years. No fun

[trike savior]

if hub wont come off heat with oxy acetylene torch. till its good and hot, does not need to be red hot. let it cool a bit and few knocks with will get it right off. if you hit it when its hot the metal can bend easy. hate to make it sound like my answer for everything is torch it but it works. heat makes metal expand and thats what you need in that situation

If all else fails, you could weld an inexpensive wrench to the nut and that should get the nut off.

[symfrog]

Is the other side off? If so you should be able to tap the hub on a little farther exposing more of the axel nut.

[trike savior]

like both of symfrogs ideas
noticed in pics i see a set of blue forks, do you have a blue 110 puffine. if so cool, me too

[kb0nly]

Situations like that i would take a nut of the same size and sit it over that nut and then weld in a few spots around it, welding the new nut to the old nut giving you a new nut to put the wrench on.

Otherwise i agree with trike savior, nothing beats the blue tip wrench!

thanks for all the tips guys i will try getting some heat on it if that fails then weld on another nut. I will keep u guys updated. Trike savior yes its a blue 110 i just took the rear plastics off it because i take it in the trails and dont want to damage them. I believe this little 70 was originally orange and i also have a green US90 that i recently picked up.

lots of good ideas they'll all work

i would avoid the chisel method, i havve done it many times, but it is a bit of an art form, you should use a slightly dull chisel and 3 lb ,

1. i would spray it with rust penetrant overnight, take a 6 point socket [not 12], grind the face down untill the little radius is gone, heat with torch [if you have one] until the nut looks barely red [not too red, hot] should come off.

2. weld nut or wrench to it.

The heat will help save your axle threads.

Also....cut a 1/4 inch off yer socket......Itll be all bite, and it get rid of the chamfer at the end.....old harley sprocket nut trick.

Very good trick that i forget to suggest sometimes. I have a whole set of sockets that i took to a local metal fab shop and had him chuck up in the lathe, he cut them down till they had no chamfer on the end and then had him add a chamfer to the outside edge, they get into anything!! The way a socket should be.

hello

yeah that's why i mentioned grinding the face down. the lathe is obviously the best but it;s not practical for most people trying to do this at home but more people might have some sort of grinder.
