Having trouble removing the swingarm from my RT3. I have the left side nut removed but it won't push through. The right side only has a two sided wrench edge with a grease fitting. It will turn with quite a bit of wrench pressure. I've hammered on it with a plastic hammer but it's solidly in place.  I haven't applied heat yet. I'm guessing it still has the nylon bushings and that they're probably adhered to the swingarm bolt. Any tricks to this? I've checked the forum search and the answer is probably buried in there somewhere but I haven't located anything yet.

BIGGER HAMMER, just protect the threads with a block of wood before beating the hell out of it

Huge thank you for the advice. Getting the frame and swingarm prepared for powder coating this week. Hope to post some pics at some point on the progress. 

This is what i wrote ages ago below. Pic from post won't load so i'll link the page. I see it was type going through the crankcase "which yours isnt" but same methods apply. Needs a good solid smack.
Heavy tube with a good foot over the bolt head. Then solid object, crank pin in this case--then a large steel sledge hammer. Its gotta move. This pic was my suzuki farm bike so not going through the back of the crankcase like i guess your IT175 is but same method applies. We used this method at work--when i worked--but pic is of at home recently. Arm bolt was rusted into the sleeves--call then spacers through the bushes. Yours will be like 'that' but stuck through the crank case as well. This is why it needs supporting solid on the far end. Have my steel foot on the concrete, not soft ground. I used to have a crankpin with a long handle to get someone brave to hold it but lost it so just balanced a crankpin on the end & don't miss with the hammer. Might be a good idea to leave the nut flush with the end of the thread while hitting although bolt will likely be damaged regardless but at least it will be out.

I was just looking for RT325's old post and pic but see it's linked to now. 

If you really need to wail on it, supporting is essential.   I used to use a length of pipe up against a steel beam of shed with bike on its wheels...  used tie downs to hold bike standing with pipe over head of swingarm bolt up and pipe tight against beam. 

RT325's  method is better to get a good swing.

I tried to get basically bare frame into press but opening between uprights wasn't wide enough...  If you know someplace with a large press, that would be best....  but again need to support frame or you can bend things you don't want to bend. 

I've always wanted to try an induction heater on something like this. Not sure if it would work with bolt being so long but I have seen induction heaters work miracles on rusted fasteners. Maybe someday I'll win the lottery and get one.

This 20 ton hydraulic press from Home Depot has a 21"  vertical opening with the bottom rail set on the lowest position and the ram has a 6" stroke. I prefer to use heat, penetrating oil and a gentle approach to applying extreme force.

I'll upload a picture when I can.

It was the horizontal opening that was the problem with the press we had at work.  Frame needs to fit through uprights on its side and it was a couple inches too narrow.

I got a surplus press for free several years ago that's wide enough...  it's a monster...  but is in pieces and needs rebuilding.  I plan to assemble someday and see if I can use a bottle jack instead of the fancy ram and electric pump that are leaking.  Too many projects.  

Wow, RT. That is some setup. Maybe I'll just start by soaking it for a few days and will add a bit of heat and see if I can press it out under the frame of my 4x4 with a floor jack and a few pieces of pipe. I think the bolt will give before it lifts the truck off the ground. I do have access to a press that might work, that would be easier. Good tips everyone. Thank you.

what's the ID of that induction heater? would a brat fit?
